IRPH Refund in Spain: Can Borrowers Recover Overpaid Interest?

Many borrowers in Spain may have paid significantly more interest because their mortgage was linked to the IRPH index instead of Euribor.

For years, IRPH mortgages often produced higher interest rates than other reference indexes. As a result, many homeowners paid thousands of euros more than they would have paid under a Euribor-based mortgage.

Following several rulings by the Court of Justice of the European Union and decisions by Spanish courts, borrowers may be able to challenge IRPH clauses and recover overpaid interest.

What Is an IRPH Refund?

An IRPH refund refers to the repayment of interest that a borrower may have overpaid due to the use of the IRPH index in their mortgage contract.

If a court determines that the IRPH clause was not transparent or properly explained, the clause may be declared abusive. When this happens, the mortgage interest may be recalculated using a different index, which can lead to a refund of excess payments.

In many cases, borrowers recover the difference between what they paid under IRPH and what they would have paid under a more common index such as Euribor.

Why Borrowers May Be Entitled to a Refund

European consumer protection law requires banks to provide clear and transparent information about mortgage terms.

When IRPH mortgages were sold, many borrowers were not given enough information about:

• how IRPH is calculated
• how IRPH compares to Euribor
• the long-term financial impact of the index

Because of this lack of transparency, courts may consider the IRPH clause abusive.

If the clause is declared abusive, borrowers may be entitled to recover the additional interest they paid.

How Much Money Can Be Recovered?

The amount of an IRPH refund depends on several factors, including:

• the mortgage amount
• the duration of the loan
• the difference between IRPH and Euribor over time

In many cases, borrowers may have overpaid thousands of euros in interest.

A legal analysis of the mortgage contract is usually required to estimate the potential refund.

Who Can Claim an IRPH Refund?

Borrowers who signed a mortgage linked to IRPH may be able to request compensation if the clause was not properly explained.

This may apply to:

• Spanish homeowners
• foreign property buyers
• investors who purchased property in Spain

European consumer law protects borrowers regardless of nationality.

How to Check if Your Mortgage Uses IRPH

The interest rate index used in a mortgage is specified in the mortgage deed.

You should look for references such as:

• IRPH Entidades
• IRPH Cajas
• IRPH Bancos

If one of these indexes appears in the contract, your mortgage may have been calculated using IRPH.

You can learn how to identify the clause by reading our guide on how to review an IRPH mortgage deed in Spain.

What Happens If the IRPH Clause Is Declared Abusive?

If a court determines that the IRPH clause is abusive, the court may:

• remove the IRPH clause from the mortgage
• replace the index with another reference rate
• recalculate the interest paid
• order the bank to refund overpaid interest

The exact outcome depends on the circumstances of each case.

Many borrowers first estimate how much interest they may have overpaid before deciding whether to start a legal claim.
