How do I handle early repayment charges when selling my house with a mortgage?

Handle an early repayment charge by establishing whether your planned completion date falls within the charge period, confirming the amount with your lender, and allowing for it when assessing the net proceeds from the sale. The charge is a contractual mortgage cost, so choosing a different type of buyer does not by itself remove it.

When an ERC may apply

An ERC commonly applies when a mortgage is repaid during a fixed-rate, discounted-rate or other introductory period. The exact conditions depend on the mortgage contract. The charge may be calculated by reference to the balance being repaid, the date of redemption, or a stepped schedule that changes during the product period. It is therefore unsafe to estimate it from the original loan amount or assume that the charge remains the same throughout the year.

Some mortgages have an ERC that ends on a specified date, while others apply a different charge at different stages of the deal. Your lender may also distinguish between repaying the mortgage in full, making an overpayment and transferring the mortgage product to another property. The relevant date is usually connected with redemption of the loan, so ask the lender how the proposed completion date affects the calculation.

Review the mortgage terms before committing to a completion date

Look for the sections covering early repayment, overpayments, product transfer and mortgage redemption. These provisions can explain:

• the dates during which an ERC is payable;
• how the charge is calculated or reduced over time;
• whether an annual overpayment allowance is available;
• whether any separate administration or redemption fees apply; and
• what happens if the mortgage is moved to a replacement property.

If the wording is unclear, ask the lender or your conveyancing solicitor to interpret the practical effect for your sale. Do not rely on a general statement that the charge will disappear at the end of a fixed period; the mortgage terms and the actual redemption date determine the position.

Consider whether porting is suitable

If you are selling because you intend to buy another home, your mortgage may be portable. Porting normally means applying to transfer the existing mortgage product to the new property rather than redeeming it entirely. This may reduce or avoid an ERC, but it is not automatic. The lender will generally need to approve the new borrowing and assess the replacement property and your circumstances. The new purchase must also complete in a way that fits the lender’s requirements.

Porting may not cover any extra borrowing required for the next property. Additional borrowing could be placed on a different product, with separate terms and costs. If the purchase does not proceed, or the lender does not approve the transfer, the original mortgage may still need to be repaid and the ERC may then become relevant.

Compare the cost of waiting with the cost of selling now

Where a charge is due to expire, compare the likely cost of delaying completion with the practical cost of waiting. A later sale date may affect mortgage interest, insurance, council tax, maintenance and the timing of another purchase. Conversely, bringing completion forward may trigger an ERC that would otherwise have ended. Your solicitor can help identify the date on which the mortgage must be redeemed, but only the lender can confirm the applicable charge.

Do not agree a completion date solely on the assumption that a short delay will remove the ERC. Confirm the date and amount in writing, particularly if the charge changes during the mortgage term or if the sale involves more than one borrower or secured loan.

Build the charge into the completion finances

On completion, the conveyancing solicitor normally uses the sale proceeds to repay the mortgage and other secured sums before transferring the remaining balance to you. The ERC therefore reduces the money left after completion. Your financial calculation should also allow for legal fees, estate agency costs where applicable, outstanding mortgage interest and any other amount secured against the property.

If the expected sale proceeds will not cover the mortgage redemption figure and the ERC, tell your solicitor and lender before exchange of contracts. The lender may require an agreed plan for any shortfall before it consents to release its security. A buyer’s offer does not cancel the debt, and completion cannot simply proceed on the basis that the remaining balance will be dealt with later.

Do not make a voluntary payment without checking first

An available overpayment allowance can sometimes reduce the balance used in the final redemption calculation, but making an extra payment does not necessarily eliminate an ERC. It could also affect the amount needed to complete the sale or create a separate charge under the mortgage terms. Ask the lender to explain the effect of any proposed overpayment before sending funds.

The safest approach is to obtain a current redemption calculation, confirm whether the proposed completion date falls inside the ERC period, and ask how porting or an authorised overpayment would alter the amount. Give the confirmed figure to your conveyancing solicitor so the sale statement reflects the actual cost rather than an estimate.
