What are early mortgage repayment charges and how can they affect the selling process?
Early mortgage repayment charges (ERCs) are fees your lender may apply when you repay a mortgage before the end of a fixed, discounted or other agreed period. When selling, an ERC is added to the amount needed to redeem the mortgage, increasing the selling costs and reducing the funds left from the sale.
An early mortgage repayment charge (ERC) is a contractual cost applied when a mortgage, or part of it, is repaid during a period when the lender has agreed to fixed or specially priced borrowing. In a sale, it is normally treated as part of the mortgage redemption figure, so it must be allowed for when calculating the amount of equity likely to remain after completion.
How the charge is calculated
The method depends on the mortgage product and the lender’s terms. An ERC may be set as a percentage of the outstanding balance, a fixed amount, or a stepped charge that reduces as the product approaches its end date. Some mortgages have separate rules for partial repayments, overpayments or repaying only one sub-account of a larger mortgage.
The charge is not necessarily based on the original loan. It may relate to the balance outstanding when the lender receives the repayment. This means that regular capital repayments could reduce the balance on which an ERC is calculated, but the precise treatment must be confirmed with the lender.
Where it appears in the selling process
Your conveyancer will usually request a redemption statement from the mortgage lender. This statement sets out the amount needed to clear the mortgage on a specified date and should identify any ERC, interest, administration fee or other redemption-related cost. The figure is date-sensitive, so a statement obtained early in the transaction may need to be updated before completion.
On completion, the buyer’s funds are transferred through the conveyancing process. The lender is paid the redemption amount first, including any applicable ERC, and the remaining balance is then passed to you after other authorised deductions. If the sale price does not cover the mortgage and its associated costs, you may need to provide additional funds or obtain the lender’s agreement to an alternative arrangement.
Why an ERC can affect your selling strategy
- It reduces net equity: the charge comes out of the money available after the mortgage is redeemed, rather than being an expense that is normally paid separately at the start of the sale.
- It can affect the minimum acceptable price: when comparing offers, assess the expected net proceeds after the mortgage balance, ERC, estate agency costs, legal fees and other selling expenses.
- Timing can matter: if the charge ends on a known date, completing after that date may remove the ERC. However, delaying can involve additional mortgage interest, insurance, maintenance and other ownership costs, as well as the possibility that the eventual sale price or transaction terms change.
- It can influence the choice of buyer: a sale requiring fewer stages may be preferable where the aim is to reach the relevant mortgage end date or avoid a transaction extending beyond a lender’s quoted redemption period. A cash sale does not automatically remove an ERC; the mortgage still has to be redeemed under the lender’s terms.
Options that may reduce or avoid the charge
Check whether your mortgage is close to the end of its ERC period before deciding when to market or complete. Ask the lender for the exact date on which the charge ends and whether the relevant date is the date of completion, the date funds are received, or another date specified in the mortgage conditions. Do not assume that exchanging contracts after the charge period ends is sufficient.
If you are moving to another property, ask whether the mortgage is portable. Porting may allow the existing product to be transferred, subject to the lender’s assessment and the terms of the new borrowing. It does not always avoid every cost, and borrowing more or less than the existing balance can lead to separate product, valuation or arrangement requirements.
You can also ask whether a permitted overpayment allowance is available. Making an overpayment may reduce the balance, but it may not remove an ERC and an overpayment above the permitted amount could itself attract a charge. The lender should confirm the consequences before any payment is made.
In some circumstances, a lender may have specific provisions for transferring a mortgage, changing products or dealing with exceptional events. These provisions vary considerably. Any suggestion that an ERC can be waived should be obtained in writing from the lender rather than assumed from general guidance.
Practical steps before accepting an offer
- Read the mortgage offer, annual statement and current product conditions for the ERC period and calculation method.
- Request a redemption statement and ask the lender to explain each charge included in it.
- Confirm how the figure changes if completion takes place on different dates.
- Give the redemption information to your conveyancer and ask for an estimated completion statement showing the expected net proceeds.
- Compare the cost of completing during the ERC period with the total cost and risks of waiting.
- Check whether any additional mortgage, legal, agency or property costs will arise while the sale is being arranged.
If you are considering a cash sale, the relevant comparison is not simply the headline offer. Set the proposed price against the mortgage redemption figure, including the ERC, and all other selling costs. This gives a more accurate view of the money you would retain and helps you judge whether the certainty and structure of the proposed transaction suit your circumstances.

Early mortgage repayment charges can be more complicated where a mortgage is divided into several sub-accounts. Each part may have its own interest rate, end date and repayment conditions, so selling the property could trigger a charge on one sub-account even if another part is outside its early repayment period.
Ask the lender for a breakdown showing the balance and repayment terms for each sub-account, rather than relying only on the total mortgage balance. Give this information to your conveyancer so the estimated completion statement reflects the correct redemption costs. This is particularly important where the mortgage has been changed, increased or partly fixed during its term, as different borrowing segments may not share the same ERC conditions.
