Are there penalties for early repayment of a mortgage during a home sale?
Yes, repaying a mortgage when selling your home can trigger an early repayment charge (ERC), particularly if the sale completes during a fixed-rate, discounted or other early-repayment period. Check your mortgage offer or ask your lender for a redemption statement, which should show any ERC, outstanding balance and other repayment costs before you commit to the sale.
An early repayment charge (ERC) is a fee your mortgage lender may apply when the mortgage is repaid before the end of an agreed deal or early-repayment period. Selling the property usually requires the mortgage to be redeemed on completion, so an ERC can be payable even when the repayment results from a sale rather than a voluntary overpayment.
When an ERC may apply
ERCs are most commonly attached to fixed-rate, discounted-rate and some tracker mortgages. The charge normally applies only during a specified period set out in the mortgage offer. That period may end before the mortgage’s full contractual term, so check the precise end date rather than assuming that the charge lasts until the final mortgage payment.
Your mortgage terms should explain:
- the dates on which an ERC applies;
- how the charge is calculated;
- whether the charge changes as the repayment period progresses;
- any annual overpayment allowance; and
- whether other administration, discharge or exit fees are payable.
An ERC is separate from the outstanding capital and interest due on the mortgage. It is also separate from a lender’s administration or mortgage discharge fee, although all applicable amounts may appear together on the redemption statement.
Cases where a charge may not be payable
No ERC is normally due once the relevant early-repayment period has ended, provided the mortgage is redeemed after that date. Some mortgages also allow a limited amount of capital to be repaid each year without an ERC. However, using an overpayment allowance does not automatically remove the charge on the remaining balance when the property is sold.
Some products include a porting feature, allowing the borrower to transfer the mortgage to another property. Porting is subject to the lender’s criteria and may involve a new affordability assessment, valuation and mortgage application. If the existing mortgage is repaid and replaced rather than transferred, an ERC may still arise. The lender should confirm how its rules apply before a sale is committed to.
There may also be specific contractual or lender-based exceptions, but these should not be assumed. A change in circumstances, financial difficulty or the fact that the property is being sold does not by itself guarantee that the lender will waive the charge. Ask for any proposed waiver or exception in writing.
How the cost is established
Request an up-to-date redemption statement from the lender and give the intended completion date. The statement should set out the balance required to redeem the mortgage on that date, including any ERC and other applicable fees. A redemption figure can change if completion moves, interest continues to accrue, or the early-repayment period expires between the statement date and completion.
Check whether the statement is valid only for a particular date or short period. If the sale is delayed, ask for a revised figure rather than relying on an earlier calculation. Your conveyancer normally obtains or verifies the final redemption figure and arranges for the mortgage to be paid from the completion monies, but you remain responsible for checking that the lender’s terms are understood.
Ways to reduce or avoid the cost
- Compare the cost of completing during the ERC period with waiting until it ends, taking account of mortgage interest, property costs and the risk that the sale terms may change.
- Ask the lender whether completion on or after the ERC end date would remove the charge.
- Check whether the mortgage can be ported if you are buying another home.
- Use any permitted overpayment allowance only after confirming how it interacts with the planned redemption.
- Obtain written confirmation of any waiver, refund or exception before relying on it.
Waiting may not always be financially preferable. For example, continuing to pay interest and other ownership costs could outweigh the ERC, while a delayed transaction could affect the buyer or the agreed sale. The comparison should use the lender’s current redemption figures and the likely completion date rather than an estimate based solely on the original mortgage paperwork.
What happens if the sale price is insufficient
The sale proceeds must be enough to cover the mortgage redemption figure and any other sums secured against the property before the lender will release its charge. If the proceeds do not cover the balance, the shortfall is not an ERC; it is a separate repayment problem. Speak to the lender and conveyancer before exchange of contracts, as additional funding, a negotiated arrangement or another solution may be required.
Do not exchange contracts assuming that the buyer’s funds will cover the mortgage until the full redemption figure has been checked. Include the ERC and all lender charges in the financial calculation, alongside conveyancing costs and any other costs connected with the sale. This establishes whether the proposed transaction can complete without leaving an unexpected amount to pay.

An early repayment charge is generally assessed when the mortgage is actually redeemed, not when the property is listed or when an offer is accepted. This means the completion date can affect whether the charge applies, particularly if it falls close to the end of the lender’s early-repayment period.
Before agreeing contractual dates, ask the lender to confirm the relevant redemption date and whether the charge would still apply if completion moves. Your conveyancer can then use that information when coordinating the sale and mortgage repayment.
