How do early repayment charges work?

26th March 2026

By Simon Carr

Early Repayment Charges (ERCs) are fees imposed by lenders when a borrower repays a loan or mortgage either partially or in full earlier than stipulated in the contract, typically during an introductory fixed-rate or discounted period. Understanding these charges is essential for anyone considering remortgaging, selling their property, or making large lump-sum overpayments.

TL;DR: Early Repayment Charges are fees charged by lenders if you repay more than your allowed annual overpayment limit, or pay off the entire loan, typically within an introductory deal period. They are usually calculated as a percentage of the amount being repaid early and decrease over the deal’s duration.

Understanding How Early Repayment Charges Work in UK Finance

Taking out a significant loan, such as a mortgage or a secured homeowner loan, often involves a contractual agreement that lasts many years. To offer competitive interest rates, lenders often secure the commitment of the borrower for an initial period—known as the ‘product period’ or ‘tie-in period’—which typically lasts between two and five years.

The Early Repayment Charge (ERC) is the mechanism lenders use to recover the expected profit margin lost if the borrower breaks this contract early. If you repay the loan in full, or make an overpayment that exceeds your annual allowance while within this contracted period, you may incur an ERC.

What Exactly are Early Repayment Charges (ERCs)?

An Early Repayment Charge is a penalty fee stipulated in your loan agreement. It is not an arbitrary fee; it is a calculation designed to compensate the lender for the administrative and funding costs associated with the loan, which they lose if the principal amount is returned ahead of schedule.

ERCs primarily apply to products that offer a preferential rate for a limited time, such as:

  • Fixed-rate mortgages or secured loans.
  • Tracker mortgages (which track the Bank of England base rate plus a margin).
  • Discounted variable rate loans.

Once the introductory product period ends, the loan typically reverts to the lender’s Standard Variable Rate (SVR), and at this point, Early Repayment Charges generally cease to apply, giving the borrower flexibility to switch or repay the loan without penalty.

How are Early Repayment Charges Calculated?

The calculation of an ERC is defined clearly in your loan offer and varies between lenders and products. ERCs are almost always calculated as a percentage of the amount being repaid early, whether that is the full remaining balance or just the overpaid amount.

The Sliding Scale

Most common ERC structures use a sliding scale, meaning the charge reduces the longer you remain in the fixed-rate product. This rewards borrowers for staying closer to the agreed term.

For example, for a five-year fixed-rate mortgage, the ERC structure might look like this:

  • Repayment in Year 1: 5% of the capital repaid.
  • Repayment in Year 2: 4% of the capital repaid.
  • Repayment in Year 3: 3% of the capital repaid.
  • Repayment in Year 4: 2% of the capital repaid.
  • Repayment in Year 5: 1% of the capital repaid.

If you have a loan with an outstanding balance of £100,000 and choose to repay it completely in Year 3 (when the ERC is 3%), the penalty would be £3,000 (3% of £100,000).

When Do ERCs Apply to Overpayments?

Many UK loan and mortgage products allow borrowers to make annual overpayments without penalty. This is typically limited to 10% of the outstanding loan balance per year.

If your initial loan balance was £200,000, you would typically be permitted to overpay up to £20,000 in the first year without triggering an ERC. If you were to repay £25,000, the 10% ERC would only apply to the excess amount of £5,000.

It is crucial to check the specific terms of your agreement, as some specialist loans or bridging finance products may have different or stricter overpayment rules. You should always confirm the exact terms with your lender before making any significant lump-sum payments.

Understanding ERCs in Secured Lending

When dealing with secured loans, such as second charge mortgages, the implications of Early Repayment Charges need careful consideration, especially if you plan to consolidate debts or sell the property soon. If the secured loan uses a percentage-based ERC structure, that fee will be added to the redemption figure (the amount needed to pay off the loan). This fee must be paid before the security (your property) is released.

If you are considering paying off a secured loan early, it is essential to request a precise redemption statement from your lender. This statement will detail the exact total repayment figure, including any applicable Early Repayment Charges and any outstanding interest accrued.

Crucial Risk Warning for Secured Loans

If you take out any loan secured against property, including mortgages or bridging finance, you must be aware of the inherent risks. Your property may be at risk if repayments are not made. Consequences of default can include legal action, repossession, increased interest rates, and additional charges which compound your debt.

Avoiding or Minimising Early Repayment Charges

While ERCs are a contractual obligation, there are several methods UK borrowers typically use to avoid or minimise paying these fees:

  • Wait for the Product Period to End: The simplest way to avoid an ERC is to wait until your fixed or discounted rate period expires. Once you switch to the lender’s SVR, you can typically repay the loan without charge.
  • Use the Overpayment Allowance: Stick strictly to your annual overpayment allowance (often 10%) if you wish to reduce your balance during the deal period.
  • Porting Your Mortgage: If you are selling your property and buying a new one, many mortgage products are ‘portable’. This means you can transfer the outstanding mortgage balance, including the remaining ERC period and interest rate, to the new property. This allows you to avoid the charge entirely, provided you complete the new purchase quickly and meet the lender’s criteria.
  • Borrower Due Diligence: Before you commit to a new loan, always read the Key Facts Illustration (KFI) or Mortgage Illustration (MI) provided by the lender or broker. This document legally specifies the exact structure and duration of any Early Repayment Charge.

People also asked

What is the typical length of an Early Repayment Charge period?

ERCs usually run concurrently with the introductory interest rate deal, which is typically two, three, or five years. For example, if you take out a five-year fixed-rate mortgage, the ERC will normally apply for those same five years.

Is it always worth paying the ERC to switch to a better rate?

Not always. You must perform a financial calculation comparing the cost of the ERC (and any associated exit fees) against the total savings you would make from the lower interest rate over the remaining period of the original deal. Often, if you are nearing the end of the ERC period, it is cheaper to wait.

Can Early Repayment Charges be negotiated?

Once an ERC is part of a signed contract, it is legally binding and generally non-negotiable, unless there are demonstrable administrative errors in the charging. However, if you are experiencing severe financial difficulty, some lenders may offer temporary forbearance measures, though this usually does not involve waiving the ERC itself.

Do second charge loans always have Early Repayment Charges?

Most fixed-rate second charge loans will include an ERC structure similar to a standard mortgage. However, some specialist products, particularly those with higher variable interest rates, may be designed without an ERC, offering greater flexibility from the outset.

What is the difference between an ERC and an exit fee?

An ERC is a penalty specific to paying off the loan early within a defined introductory period. An exit fee (sometimes called an administration fee or deed release fee) is a small administrative charge levied by the lender when the mortgage account is closed, regardless of when it is repaid.

In summary, Early Repayment Charges are a standard feature of beneficial interest rate products in the UK secured lending market. Always ensure you thoroughly read and understand the ERC clauses in your loan documentation, paying close attention to the percentage structure, the applicable duration, and the rules governing penalty-free overpayments, as this information is key to managing your borrowing costs effectively.
