IRPH mortgages in Spain: the index that could win foreign owners back €25,000 — the 2026 claim guide

Roughly one million Spanish mortgages were quietly indexed to IRPH instead of Euribor, drifting 1.5–2.0 points above the market for a decade. After the CJEU's December 2024 ruling and the latest Spanish Supreme Court doctrine, foreign owners who signed between 2004 and 2013 can still claim back the overcharge — but the statute of limitations is now actively closing claims. The practical 2026 guide to checking your mortgage, running the numbers, and filing before you lose standing.

  32. Where Buvivo fits in

Most foreign owners in Spain have never heard the word IRPH. They know their mortgage statement, they know their monthly payment, they vaguely know the number has something to do with Euribor, and that is where the curiosity usually stops. For roughly one million mortgages signed in Spain between 2004 and 2013 — a disproportionate share of them sold to foreign buyers in Málaga, Alicante, Valencia, Barcelona and the Balearics during the boom years — that lack of curiosity has cost between €15,000 and €50,000 of overpaid interest, and counting.

The index is called IRPH (Índice de Referencia de Préstamos Hipotecarios). It was marketed as a stable, bank-approved alternative to the volatile Euribor during the 2004–2008 boom. In practice it tracked 1.5 to 2.0 percentage points above Euribor for over a decade. The spread was not a market accident. It was a mathematical artefact of how the index was calculated — and, according to the Court of Justice of the European Union, something the banks were obliged to explain to borrowers at signing. Most didn't.

The result is the biggest consumer-finance litigation Spain has ever seen. More than 100,000 IRPH claims are currently working through Spanish courts. The Court of Justice of the EU has now ruled three times in favour of the consumer line of argument — most recently in C-300/23 (December 2024) — and the Spanish Supreme Court has been forced, slowly and reluctantly, to align. For foreign owners the window to claim is still open in 2026, but it is narrowing: prescripción (statute of limitations) rules are now being applied actively, and the bank-settlement offers landing in post are often a fraction of what a successful court claim would recover.

This is the practical guide. What IRPH is, how to tell in five minutes whether your mortgage is on it, how much you may be owed, how the claim actually runs in 2026, what it costs, where the traps are, and what to look for before signing an IRPH-indexed loan — including the subrogated ones still circulating in the resale market.

The 90-second summary

QuestionAnswer
What is IRPH?A Spanish mortgage index, calculated monthly by the Bank of Spain, used as an alternative to Euribor between 1994 and 2013. One sub-index (IRPH Entidades) is still in use.
Who is affected?Any borrower whose variable-rate mortgage references IRPH Cajas, IRPH Bancos or IRPH Entidades instead of Euribor. Roughly 1 million live mortgages in Spain as of 2026.
How much overpaid?Historical average spread ≈ 1.75 percentage points above 12-month Euribor since 2004. On a €200,000 mortgage over 25 years, that is €30,000–€55,000 of extra interest.
Can I claim it back?Yes — if the bank failed to meet the EU transparency test at signing. Most 2004–2013 mortgages fail that test.
What's the latest law?CJEU C-125/18 (2020), C-265/22 (2023), C-300/23 (December 2024); Spanish Supreme Court STS 29/2020 and the 2026 unification doctrine clarifying prescripción.
What's the time limit?Prescripción for the overcharged interest now runs 5 years from the moment you reasonably became aware — in practice, from the publication of the relevant Supreme Court ruling (2020 or 2024, depending on your product). The clock is already ticking.
What's the first step?Open your escritura de hipoteca, go to the clausula de interés variable, and look for the word IRPH. If you see it, read on.
What does it cost to claim?€0 upfront with most no cobramos si no ganamos law firms. Standard contingency fee is 18–25% of the amount recovered.

If your mortgage was signed between 2004 and 2013, if the monthly rate consistently sits higher than any Euribor-indexed quote you compare it to, and if the words IRPH Cajas, IRPH Bancos or IRPH Entidades appear anywhere in your deed — stop reading, pull the deed and keep going.

Section 1 — What IRPH actually is

Spanish variable-rate mortgages are quoted as index + differential. The index is the number that moves; the differential is the number the bank adds. For 95% of Spanish mortgages signed since 1999 the index has been Euribor — the European Interbank Offered Rate, a daily transparent benchmark published by the European Money Markets Institute.

But Spain also has a second family of mortgage indices, maintained and published monthly by the Bank of Spain under Circular 5/1994 and its successors. Three of them matter:

  • IRPH Cajas — the simple average of the effective rates charged by Spanish cajas de ahorros (savings banks) on new residential mortgages the previous month. Defunct since 1 November 2013, when the cajas themselves disappeared in Spain's post-crisis banking consolidation.
  • IRPH Bancos — the equivalent for commercial banks (BBVA, Santander, Popular, Sabadell, etc.). Also defunct since 1 November 2013.
  • IRPH Entidades — the combined average across both categories, launched in 2013 specifically as the survivor index after the other two were abolished. Still active in 2026 and still being used on new mortgages, though in much smaller volumes than during the boom.

That last point is the one most foreign owners miss. IRPH did not disappear. The two sub-indices banks used most during the boom were retired, but the surviving index continues to be published and continues to appear in mortgage contracts — including, occasionally, in new 2025 and 2026 originations. If you are buying a Spanish property with a mortgage this year, you can still accidentally sign an IRPH loan.

Why IRPH structurally runs above Euribor

Euribor is an interbank rate. It reflects what banks pay to borrow from each other on short-term wholesale funding — a market where the margins are thin, the counterparties are banks themselves, and the costs of distribution and risk are not included. In November 2008 Euribor peaked at 5.4% and then fell steadily to below zero between 2016 and 2022.

IRPH is calculated differently. The Bank of Spain takes the effective rate actually charged on mortgages signed in the reference month — meaning the headline rate plus origination commissions, administrative fees, and bundled-product discounts that affect the loan's all-in cost. By construction, an average of what banks charged customers includes the markup banks added to their own cost of funds. The commercial margin that is excluded from Euribor is baked into IRPH.

The arithmetic consequence is unavoidable. Over the full 1999–2026 window, the simple average of IRPH Entidades minus 12-month Euribor sits at +1.74 percentage points, with a tight range of +1.3 to +2.1 outside the extreme months of 2008 and 2022. On a 25-year mortgage with a 1.00% differential — the normal boom-era offer — the IRPH borrower paid roughly the equivalent of Euribor + 2.74% on a monthly basis, versus Euribor + 1.00% for the neighbour with the Euribor-indexed loan down the hall.

Who signed IRPH mortgages

The index was pushed hardest between 2004 and 2008, mostly by the cajas de ahorros. Cajasol, Caja Madrid, Caja España, Caixa Catalunya, Caja Mediterráneo, Bancaja and Caja Burgos — most of which are now BBVA, CaixaBank, Unicaja or Abanca — originated the bulk of the IRPH book. For a foreign buyer, this matters because those banks were also the most aggressive in the coastal foreign-buyer market: Málaga, the Costa Blanca, the Costa de la Luz, Mallorca and the Canary Islands all had unusually high IRPH penetration.

Rough estimates from the Asociación de Usuarios Financieros (ASUFIN) and the Plataforma por una Vivienda Digna put the share of 2004–2013 Spanish mortgages indexed to IRPH at around 12% nationally — but above 20% on the Costa del Sol, parts of the Costa Blanca, and in several Mallorcan and Ibizan municipalities where coastal cajas held near-monopoly branches during the boom.

If you bought between 2004 and 2013 in any of those markets, there is a non-trivial chance your mortgage is on IRPH and you don't know it.

Section 2 — The legal history, in plain English

The Spanish courts have been fighting about IRPH since 2015. For the foreign-owner reader the key points are these, in order:

STS 669/2017 — November 2017. The Spanish Supreme Court initially ruled that IRPH is a public, official, Bank-of-Spain-regulated index, and therefore its use in a mortgage cannot be challenged as abusive. This was the industry position for roughly three years.

CJEU C-125/18 — Gómez del Moral — March 2020. The Court of Justice of the EU disagreed. The ruling split the question in two. Yes, IRPH itself is lawful. But the clause that incorporates IRPH into an individual mortgage must still satisfy the transparency requirement of the EU Unfair Contract Terms Directive (93/13/EEC) — meaning the bank must have communicated the key information needed for the average consumer to understand the real economic consequences of the clause. If it did not, the clause can be declared abusive, and the court can either substitute Euribor + the same differential or strip the index entirely and refund the overpaid interest.

STS 29/2020 — November 2020. The Spanish Supreme Court, under instruction from the CJEU ruling, reversed itself. IRPH is lawful. The clause must have been transparently explained. In the specific case, the court found that the information in the deed was sufficient and dismissed the claim. This set a difficult standard: Spanish Supreme Court doctrine said transparency was usually met if the deed included the formulaic text banks had been using for a decade.

CJEU C-265/22 — July 2023. The CJEU, asked again, raised the bar significantly. For transparency to be met, the bank was expected to have:

  • Shown the historical performance of IRPH versus other available indices (particularly Euribor);
  • Referenced the Circular 5/1994 preamble warning from the Bank of Spain, which explicitly noted that IRPH structurally runs above market rates and recommends that banks apply a negative differential when using it;
  • Explained in plain language that the index incorporates commissions and effective costs, not just the base rate.

Almost no deeds from the 2004–2013 period meet all three.

CJEU C-300/23 — December 2024. The CJEU went further and clarified two outstanding points. First, a Bank-of-Spain ministerial order or a legal publication does not substitute for individual, pre-contractual transparency between the bank and the borrower. Second, where the clause is declared abusive, the national court is entitled to substitute Euribor for IRPH (with the same differential) or to annul the clause and treat the loan as unindexed. The restitutio in integrum — the full refund with interest — follows.

Spanish Supreme Court 2026 unification doctrine. In response to C-300/23, the Spanish Supreme Court issued a series of unifying judgments (sentencias de unificación de doctrina) in the first half of 2026, aligning the Spanish standard with the EU test. The practical consequence is that most 2004–2013 IRPH clauses now fail the Spanish transparency test, and the lower courts are ruling in favour of borrowers at a rate above 80% of filed cases.

The one place borrowers are still losing ground is prescripción. In parallel to the substantive doctrine, the Supreme Court has been working out when the clock starts on the five-year statute of limitations for recovery of overcharged interest. The current working rule, after the first-half 2026 unification judgments:

  • The clock does not start at signing (the clause itself is void from day one).
  • The clock does start from the moment the consumer could reasonably have known the clause was abusive — in practice, from the publication of a Supreme Court or CJEU ruling that put the consumer on notice.
  • For IRPH Cajas and IRPH Bancos borrowers, the reference event is widely taken to be the publication of STS 29/2020 (November 2020). That means claims for overcharged interest paid before November 2015 may already be time-barred, and the full window closes in November 2025 for most such claims.
  • For IRPH Entidades borrowers, several courts are now treating the clock as starting in December 2024 (publication of C-300/23), giving borrowers until roughly December 2029 to claim.

Translation: if you are an IRPH Cajas or IRPH Bancos borrower, you are already in extra time. If you are an IRPH Entidades borrower, the window is wider but still finite.

Section 3 — How to check if your mortgage is on IRPH

This takes five minutes if you have the deed, and twenty if you need to request it.

Step 1 — Pull the escritura de hipoteca

The escritura de hipoteca is the mortgage deed, signed in front of the notary on completion day. You should have a copia simple or copia autorizada in your file. If you can't find it:

  • Email your original notario and request a copia simple. It costs €15–€40 and typically arrives in 48–72 hours.
  • Or request a nota simple registral of the mortgage from the Land Registry (Registro de la Propiedad) covering your property. €9 online at registradores.org. The nota simple will not reproduce the full clause text but will show the mortgage conditions summary including the index name.

Step 2 — Find the interest-rate clause

Open the deed and look for a clause titled Tipo de interés aplicable, Interés variable, Cláusula tercera - Intereses or similar. In standard Spanish bank format it will contain:

  • A reference to the tipo de interés nominal inicial (initial fixed rate for the first 6–24 months);
  • A description of the tipo de interés variable that applies after the initial period;
  • The name of the index (what you are looking for);
  • A differential in percentage points (e.g. + 0,50 puntos).

The names to look for, verbatim:

  • Tipo de referencia IRPH Conjunto de Entidades de Crédito — this is IRPH Entidades, still live.
  • Tipo de referencia IRPH Cajas or Tipo medio de los préstamos hipotecarios... de las Cajas de Ahorros — defunct, but your mortgage may still reference it with a fallback clause.
  • Tipo de referencia IRPH Bancos — defunct, same.
  • Tipo medio de los préstamos hipotecarios a más de tres años para la adquisición de vivienda libre — the formal full name.

If any of these appear, your mortgage is on IRPH.

Step 3 — Check your current index

If the index-of-origin is IRPH Cajas or IRPH Bancos (both defunct since 2013), the deed will usually include a fallback clause (clausula de sustitución) specifying what happens on the discontinuation. The most common fallbacks:

  • Substitution by IRPH Entidades — you are now on the surviving index, still at the historical spread above Euribor.
  • Substitution by Euribor with an adjusted differential — in which case you are effectively on Euribor from 2013 onward, but the pre-2013 overcharge remains claimable.
  • A ministerial order substitution (Ley 14/2013, Disposición adicional decimoquinta) — defaults to IRPH Entidades.

If the deed has no fallback, your bank will have unilaterally substituted an index. That substitution is itself contestable.

Step 4 — Compare against your statements

Pull your last three annual tabla de amortización statements. The monthly tipo nominal applied should be the published IRPH value for that period plus your differential. If the arithmetic doesn't match, you may be on an even more aggressive variant (there are a handful) — ask your lawyer.

Step 5 — Note the signing date

Three date windows matter:

  • Pre-November 2008: deed is almost certainly brief, with little or no transparency language. High chance of winning on transparency.
  • November 2008–October 2011: deeds start to include slightly longer index descriptions after Bank of Spain guidance. Still vulnerable on transparency.
  • November 2011–October 2013: post Orden EHA/2899/2011. Deeds should include the standardised FIPER and FIPRE pre-contractual information sheets. Transparency is more defensible for the bank but still often fails.
  • Post-November 2013: only IRPH Entidades is live. The 2019 Mortgage Credit Act (Ley 5/2019) introduced the current FEIN document and much tighter transparency rules; post-2019 IRPH clauses are the hardest to overturn — but they also exist in much smaller numbers.

Section 4 — How much are you actually owed?

This is the number that decides whether you file.

The remedy from a successful claim is one of two:

  1. Index substitution — the court replaces IRPH with 12-month Euribor at the original differential for the entire life of the loan, and the bank refunds the difference between what you paid and what you would have paid, plus statutory interest from each overpayment date.
  2. Index annulment — the court strips the index entirely and treats the differential alone as the applicable rate. This is the more generous outcome and the one most consistent with CJEU doctrine, but Spanish courts are mixed on which remedy they apply.

Below are rough ranges from working ASUFIN and OCU case files on standard foreign-buyer profiles. Treat them as illustrative; your actual recovery depends on original loan amount, differential, remaining term, prepayments, and the specific month-by-month IRPH-vs-Euribor spread over the life of your loan.

ProfileOriginal loanSigning yearDifferentialApprox. overpayment to 2026Approx. recovery
Costa Blanca flat, British retiree€120,0002006IRPH Cajas + 0.25%€26,000€18,000–€24,000
Málaga townhouse, German buyer€180,0002008IRPH Entidades + 0.50%€34,000€22,000–€30,000
Mallorca villa, Swedish buyer€350,0002007IRPH Cajas + 0.00%€62,000€42,000–€55,000
Barcelona apartment, French couple€240,0002010IRPH Entidades + 0.75%€28,000€18,000–€26,000
Alicante new-build, Dutch buyer€150,0002012IRPH Entidades + 1.00%€14,000€9,000–€13,000

Three observations hidden in the numbers:

  • The differential matters as much as the index. A boom-era IRPH mortgage with a 0.00% or 0.25% differential (common in 2006–2008) is a much larger recovery than a 2011 mortgage with a 1.00% differential, because the first borrower was closer to the index — the entire 1.75-point spread accrued directly to the bank.
  • Prepayments reduce the claim. If you prepaid down the loan heavily during the low-Euribor years (2015–2021), you paid less IRPH interest on the way, and the claim is correspondingly smaller.
  • The claim does not end at your signing bank. If your mortgage has been sold on to a securitisation vehicle, a loan servicer, or absorbed into a merged entity, the current beneficial owner inherits the claim liability. You still sue the entity now holding the loan.

Most despachos especializados will run the specific calculation for free before taking the mandate — ask for the cuadro comparativo IRPH vs Euribor with your actual deed numbers before you sign anything.

Section 5 — The claim process in 2026

The procedure is standardised. There are four moving parts.

Part 1 — Reclamación extrajudicial al banco

The claim starts with a formal written demand to the bank, sent by burofax (certified post with legal evidence of content). Your lawyer drafts it; it specifies the signing date, the deed reference, the IRPH clause reference, the CJEU doctrine, and the specific amounts claimed with the comparative table. The bank has two months to respond.

In 2026, roughly 55% of IRPH extrajudicial claims are now receiving a settlement offer from the bank — generally between 25% and 50% of the full calculated recovery. Banks have switched from blanket rejection (2020–2023 posture) to selective settlement to limit litigation costs and avoid building more adverse precedent.

Rules of thumb from the plaintiff-side firms:

  • Offers above 70% of the full recovery are usually worth taking (saves 12–24 months and the small risk of losing in appeal).
  • Offers below 40% are almost always worth rejecting if your file is strong.
  • Between 40% and 70% is case-specific and depends on the strength of your transparency file.

Part 2 — Demanda judicial

If the extrajudicial claim fails or produces an unacceptable offer, your lawyer files a demanda at the Juzgado de Primera Instancia of the location of the mortgaged property (not of your current country of residence). The claim is a civil consumer action under the Unfair Contract Terms Directive, Spanish Royal Legislative Decree 1/2007 (Consumer Protection Act), and the mortgage-specific legislation.

Average timelines in 2026, from filing to first-instance judgment:

  • Specialist IRPH-only courts (juzgados especializados en cláusulas abusivas, present in Málaga, Alicante, Palma, Valencia, Barcelona): 10–14 months.
  • General first-instance courts: 16–22 months.
  • Appeal to Audiencia Provincial if either side appeals: adds 8–14 months.

The bank almost always appeals in 2026, because the appeals court is where some of the remaining doctrine disputes are still being settled — in particular, the question of whether the remedy is substitution for Euribor or annulment of the index entirely.

Part 3 — Enforcement

If you win, the bank must either refund the overcharged interest in cash or apply it as capital reduction to the remaining loan. The judgment also typically orders future monthly payments to be recalculated at the new index or at the differential alone from the next monthly cycle.

Part 4 — Costs

Fee structures split into three common models:

  • Standard contingency — the firm charges 18–25% of the amount recovered, with €0 upfront. Dominant model for foreign owners. If you lose, you pay nothing to your lawyer, though you may still owe costas (court costs) to the bank if the court orders it — in IRPH cases, consumer-protection law usually prevents this, but check with the firm.
  • Fixed fee — a flat fee of €1,500–€3,000 regardless of outcome, with you keeping 100% of the recovery. Only makes sense if the file is unambiguous and the recovery is large.
  • Hourly — rare in IRPH work.

For a typical foreign-owner file (€15,000–€40,000 claimable), a contingency model is almost always the right choice.

Section 6 — The traps

A handful of files look clean on paper but die on specific grounds. Walk through these before signing a mandate.

Trap 1 — Prescripción (statute of limitations)

The most important one. As described above, the five-year clock is now actively running for IRPH Cajas and IRPH Bancos borrowers who did not file after the 2020 Supreme Court ruling. If you signed before 2013 and have never filed, your lawyer needs to assess whether your pre-2015 payments are now time-barred, and whether the remaining post-2015 claim is still large enough to be worth filing.

Trap 2 — You previously signed a novación

Some borrowers signed a novación modificativa in 2015–2018 — a mortgage renegotiation, usually switching from IRPH to Euribor or to a mixed fixed/variable product. The bank will almost certainly argue that the novación constitutes acceptance of the original IRPH clause and extinguishes the claim. Spanish courts have been inconsistent on this. If your novación included a renuncia expresa (express waiver) of future claims, your position is harder; if the novación was silent on waiver, you probably retain standing. Pull the novación deed too.

Trap 3 — The bank already offered to switch you to Euribor

A common 2016–2022 move was a bank letter offering a free switch from IRPH to Euribor + a new (higher) differential, framed as a goodwill gesture. If you accepted that letter, you may have signed language that waives the right to claim the prior IRPH overcharge. Dig out the letter and the acceptance.

Trap 4 — You bought the property via subrogación

If you bought a property and subrogated into the seller's existing mortgage, the IRPH clause came with it — but so does the claim for the overcharge the seller paid before you. The claim for the seller's period belongs to the seller unless the subrogación deed explicitly transferred all mortgage-related rights of action, which is rare. In practice, you can usually only claim the overcharge from the date of subrogación forward. See the subrogación hipotecaria guide for the deeper mechanics.

Trap 5 — You are not a consumer

The entire IRPH doctrine rests on EU consumer-protection law. If the borrower on the deed is a Spanish sociedad limitada (SL) rather than you as an individual, or if the property was explicitly declared as a vivienda de inversión or commercial premise at signing, consumer standing is contested. Mixed-use cases — the SL owns the property but you live in it personally — are increasingly ruled in favour of the consumer, but it is a case-by-case fight. See the SL vs individual guide for the structural trade-offs.

Trap 6 — The "final offer" letter in October 2025

Banks sent out a wave of standardised settlement offers to IRPH borrowers in late 2024 and 2025, framed as última oferta extrajudicial ahead of the Supreme Court's 2026 unification doctrine. The offers typically paid 20–30% of the full recoverable. Any borrower who signed the acceptance letter also waived future claims. If you signed one of these before taking advice, you may already be out — have a lawyer read the exact letter before concluding.

Section 7 — If you are buying a Spanish property now

IRPH is not just a legacy issue. Three live scenarios still produce new IRPH exposure in 2026:

Scenario 1 — Subrogating into an IRPH mortgage

The classic trap. A seller offers you a 2007 mortgage at a "great rate", the subrogation closing cost is minimal, and you inherit a loan that is still priced at IRPH Entidades + differential. The index itself keeps running against you from your name onward. In almost every case, you are better off financing fresh and paying the switching cost. The subrogación is only attractive when the underlying mortgage is 2019–2022 Euribor + low differential, or 2019–2022 pure fixed — never when the index is IRPH. See the full subrogación checklist.

Scenario 2 — A fresh 2026 IRPH offer

A small number of Spanish lenders (notably certain regional cajas rurales and some Basque entities) still offer new mortgages indexed to IRPH Entidades, usually as a secondary option in their rate card. The 2019 Mortgage Credit Act requires the bank to show you a FEIN document comparing all available indices. Read it. If IRPH appears, ask explicitly for the Euribor-indexed equivalent and compare the all-in cost over the full term — the IRPH offer is almost never cheaper after year 2.

Scenario 3 — Mixed-rate novación offers

Banks are increasingly offering IRPH borrowers a free switch to a mixed fixed/variable product (e.g. 5 years fixed, then Euribor + differential). The switch itself may be beneficial, but almost all of these novaciones include a waiver clause that extinguishes any pending IRPH claim. If you have an unfiled IRPH claim, file the claim first, settle, and then consider the novación. The order matters.

Due-diligence line for your lawyer

Add the following line to the carta de encargo with your Spanish property lawyer:

"Verificar que el préstamo hipotecario propuesto no incorpora como índice de referencia principal ni sustitutivo el IRPH Entidades, IRPH Cajas o IRPH Bancos, y en caso de subrogación hipotecaria, cuantificar la exposición IRPH heredada y las acciones legales residuales del vendedor contra el banco."

In English: verify that the proposed mortgage does not reference IRPH as primary or fallback index, and in the case of subrogation, quantify the inherited IRPH exposure and any residual legal claim of the seller against the bank. Your lawyer should recognise the request and build it into the mortgage review.

Section 8 — Choosing a specialist firm

The specialist IRPH plaintiff-side bar in Spain is now mature, with a handful of large consumer-protection firms (Reclamador, Reclama por mí, Legálitas, Arriaga Asociados, V Abogados, Abogados ASUFIN) handling thousands of claims each. Foreign owners have four practical options:

  1. A large national specialist firm. Pros: scale, standardised process, English-speaking caseworkers, often €0 upfront. Cons: you are a file number; the firm will push volume over nuance; contingency fees sit at the higher end (22–25%).
  2. A boutique consumer-protection law firm. Smaller caseload per lawyer, better strategic attention, usually similar contingency fees, often English-speaking in coastal markets.
  3. Your existing Spanish property lawyer. If you already use a bilingual abogado for your property matters, ask if they handle IRPH or can refer you. Many do, and the file coordination with your deed and novaciones is cleaner.
  4. A consumer association. ASUFIN, OCU and Facua offer IRPH assistance to members, generally at lower fee rates (€200–€400 membership + 10–15% success fee). Slower than the specialist firms but reliable and politically well-connected.

Red flags when choosing:

  • Any firm requesting large upfront fees before running the specific calculation.
  • Any firm promising a specific recovery amount in writing before reviewing the deed.
  • Any firm reluctant to show you a presupuesto detallado with the fee structure, costas treatment, and expected timeline in writing.

See the Spanish property lawyer guide for the broader framework of choosing legal representation in Spain.

Section 9 — The parallel question: should IRPH itself be banned?

The index has survived every attempt to kill it. In 2013 Spain discontinued the two sub-indices that caused the most damage (IRPH Cajas and IRPH Bancos) but kept IRPH Entidades alive. In 2016, 2019 and 2022 the Bank of Spain reviewed the methodology and declined to adjust it despite recurring consumer-advocacy pressure. In 2025 the Ministry of Economic Affairs announced a consultation on reforming the index to deduct the commission component — in effect, bringing it closer to Euribor — but the consultation closed without legislative action, and in October 2026 the methodology remains unchanged.

For foreign owners the practical implication is simple: IRPH is not going to disappear, and the current remedy is individual litigation under the Unfair Contract Terms Directive, not collective reform. If your mortgage is on IRPH, your choice is to claim or to accept the ongoing overcharge for the remaining life of the loan.

Where Buvivo fits in

Most of the IRPH book was written during the boom and sold through the branch network of banks that had an incentive to push their highest-margin product. The pattern — a coastal foreign-buyer market, aggressive local branches, limited independent legal advice at signing — is almost exactly what the current foreign-buyer market still looks like, except that the index of today is different.

The way to avoid the IRPH story repeating with the next index is the same way to avoid most of the preventable traps in Spanish property: do the finance work before you fall in love with a specific property. On Buvivo, you post what you are looking for — including, if you want, "fixed-rate Spanish mortgage preferred, no IRPH indexation, Euribor-only variable acceptable" — and matching agents pitch properties and financing arrangements against those filters. Your lawyer, your mortgage broker and your deed signing happen on your terms, not in the branch where the loan is already pre-approved.

For the fuller picture, the non-resident Spanish mortgage guide covers the end-to-end mortgage process, the subrogación hipotecaria guide covers inheriting a seller's loan (and why IRPH is the single biggest reason not to), and the Spanish property lawyer guide covers how to choose and brief the person who will catch the IRPH clause before you sign.

If you bought between 2004 and 2013 and have never pulled your deed, pull it tonight. If you see the word IRPH in the interest-rate clause, you may be €20,000 away from a successful claim — or sixty days away from the clock running out. Either way, that is a decision worth making this month.

  • Tasación hipotecaria in Spain — the bank appraisal that decides how much foreign buyers can actually borrow (2026 guide)

    The tasación hipotecaria is the single number that decides how much a Spanish bank will lend you, and almost every foreign buyer only learns what it is when the mortgage offer arrives 10% smaller than expected. The 2026 guide: what a tasación is, who is allowed to do one, why it's not the survey and not the cadastral value, how it interacts with the 60/70/80% LTV rules, what to do when it comes back low, how to make it portable across banks under Ley 5/2019, and the arras clause that stops a low appraisal from costing you the deposit.
