When people take out a mortgage, most of the focus naturally goes on the interest rate and the monthly payment. What many borrowers do not realise until much later is that some mortgage deals also include something called an Early Repayment Charge – usually shortened to ERC.
An ERC is simply a fee a lender may charge if the mortgage is repaid before the agreed deal period ends. This most commonly applies during fixed-rate deals, although some tracker and discounted mortgages can include them as well.
The reason these charges exist is fairly straightforward. When a lender offers a mortgage product, the pricing assumes the borrower will stay on that deal for a set number of years. If the loan is repaid earlier than expected, the lender loses some of the interest they anticipated receiving.
That is why ERCs matter. Anyone thinking about switching mortgage deals early, selling their property, or making large overpayments during the deal period will usually want to check whether an early repayment charge applies first. It is one of those details that can easily catch borrowers out.
Why Lenders Apply Early Repayment Charges
When lenders price a mortgage deal, they usually expect the borrower to stay on that rate for the full incentive period. That period might be two years, five years, or sometimes longer depending on the product.
If the mortgage is repaid earlier than planned, the lender receives less interest than originally expected. Early repayment charges are designed to offset part of that loss.
This is why many mortgage deals – particularly fixed-rate and discounted products – include ERCs during the initial deal period.
Typical Early Repayment Charge Percentages
Early repayment charges are normally calculated as a percentage of the mortgage balance that is still outstanding when the loan is repaid. In most fixed-rate deals, that percentage gradually reduces as the deal moves through its term.
For example, a five-year fixed mortgage might start with a higher charge at the beginning and then taper down each year. Many deals follow a structure along these lines:
Year 1: 5 percent of the remaining balance
Year 2: 4 percent
Year 3: 3 percent
Year 4: 2 percent
Year 5: 1 percent
What that means in reality becomes clearer when you put numbers against it. Imagine the remaining mortgage balance is £250,000.
Leaving the deal during the first year, when the ERC is still 5 percent, would produce a charge of £12,500.
By year three the percentage has usually dropped. On the same £250,000 balance, a 3 percent charge would come to £7,500.
This is why borrowers often pause before leaving a deal early. Even small percentages can quickly turn into large figures once they are applied to a six-figure mortgage balance.
How Early Repayment Charges Are Calculated
At first glance ERCs look simple because they are shown as a percentage. In practice the amount depends on a few details within the mortgage agreement.
Lenders will usually look at:
- the remaining mortgage balance
- the ERC percentage written into the deal
- where the borrower is within the deal period
- whether the repayment is partial or the mortgage is being cleared completely
The charge is normally applied to the outstanding balance at the time the loan is repaid. If the mortgage balance has already been reduced through regular payments or previous overpayments, the ERC is calculated on that lower figure.
A quick example makes this easier to picture.
Mortgage balance: £300,000
ERC rate: 3%
Early repayment charge:
£300,000 × 3% = £9,000
Even a modest percentage can produce a sizeable charge when it is applied to a large mortgage balance.
Most lenders do allow some flexibility. It is common for borrowers to be able to overpay up to around 10% of the balance each year without triggering an early repayment charge. Exceeding that allowance during the deal period is when the ERC may apply.
Because the rules vary between lenders, many borrowers check the details of their mortgage agreement before making larger repayments or switching deals.
A mortgage broker can help borrowers go over the details of mortgage offers and figure out how repayment fees might work in different situations.
Situations Where Early Repayment Charges Apply
Early repayment charges usually apply while a mortgage is still within its deal period. That is the time when the borrower is benefiting from a specific rate, such as a fixed or discounted deal.
During that period, repaying the mortgage earlier than planned can trigger a charge. It often comes up when someone decides to move their mortgage to a new lender before the deal has finished.
Selling the property can create the same situation. The mortgage has to be repaid as part of the sale, which can bring the ERC into play if the deal period has not ended.
Large overpayments can also trigger it. Many lenders allow some flexibility each year, but going beyond the permitted limit may lead to a charge.
Situations like these are often when ERCs first come to a borrower’s attention. Many people only become aware of them when their fixed rate mortgage deal ends and they begin thinking about whether to remortgage.
Until circumstances change – moving home, refinancing, or paying down the mortgage faster – the clause often sits quietly in the background.
When Early Repayment Charges Do Not Apply
Early repayment charges appear in many mortgage deals, but they are not always triggered.
One simple example is when the deal period has already ended. Once a fixed or discounted rate finishes and the mortgage moves onto the lender’s Standard Variable Rate, borrowers can usually repay the loan or remortgage without any ERC.
There are also situations where the charge may not apply even during the deal period. For example, some lenders allow the mortgage to be ported to another property, meaning the loan moves with the borrower rather than being repaid.
Most mortgages also allow limited overpayments each year. As long as those payments stay within the lender’s permitted allowance, they usually will not trigger an early repayment charge. This allowance is often around 10% of the outstanding balance each year, although the exact figure depends on the lender.
Because the rules vary between lenders and mortgage products, many borrowers review these details with a mortgage advisor before committing to a deal.
Remortgaging vs Staying With Your Current Lender
When a fixed mortgage deal is coming to an end, most borrowers find themselves looking at two options. They can move the mortgage to a different lender, or stay with the one they already have and choose a new deal.
Moving to another lender – often called remortgaging – can sometimes lead to a better interest rate. It also gives borrowers the chance to look at a much wider range of mortgage products across the market.
The timing matters though. If the switch happens before the existing deal period finishes, an early repayment charge may apply, which can make the move more expensive than expected.
Staying with the same lender can feel simpler. The process is usually quicker because the lender already holds the property information and much of the original paperwork. The trade-off is that the rates offered internally are not always the most competitive available.
Because of that, many borrowers speak to a mortgage broker before making a decision. Looking at the numbers properly can show whether switching lenders genuinely saves money once any early repayment charge is taken into account. This is especially important if a borrower is approaching the end of their deal period and trying to decide what happens if you don’t remortgage after a fixed term.
When Paying an Early Repayment Charge Might Still Be Worth It
An early repayment charge sounds like something borrowers should always avoid. In many situations that is true. But occasionally the numbers point in the opposite direction.
This usually happens when mortgage rates have moved a lot since the original deal was taken out. A borrower might be sitting on a fixed rate that is now far higher than what lenders are offering in the market.
Imagine someone with two years left on a mortgage fixed at around 6%. If new deals are available closer to 4%, the gap between those rates starts to matter quite quickly. Even after accounting for the early repayment charge, the lower rate could still lead to a meaningful saving over time.
That is why some borrowers still explore the option of switching early rather than automatically waiting for the deal to finish. The decision normally comes down to the remaining mortgage balance, the size of the ERC and how different the new interest rate really is.
Running those numbers properly usually makes the answer clearer. In some cases the charge ends up being a short-term cost that unlocks a cheaper mortgage overall.
Why Early Repayment Charges Matter When Choosing a Mortgage
When people first take out a mortgage, most of the attention goes straight to the interest rate and the monthly payment. Early repayment charges are often something borrowers barely notice at the start.
The problem is that mortgages can last many years, and life rarely stays the same over that time. Someone might move for work, decide to sell the property, refinance to take advantage of lower rates, or simply want to reduce the mortgage balance more quickly.
That is usually when ERCs suddenly become important. If the terms of the deal are not fully understood, borrowers can be caught off guard by charges when they try to make those changes.
Looking at the flexibility of a mortgage can therefore be just as important as comparing interest rates. A good mortgage broker can help borrowers see how different deals handle early repayments and whether the structure fits their longer-term plans.
Frequently Asked Questions
What does ERC stand for in a mortgage?
ERC stands for Early Repayment Charge.
It is a fee some lenders apply if a mortgage is repaid earlier than the deal allows. This usually happens during fixed or discounted mortgage deals where the lender expects the loan to stay in place for a certain number of years.
How much does an Early Repayment Charge usually cost?
Most Early Repayment Charges fall somewhere between 1% and 5% of the remaining mortgage balance.
The exact percentage depends on the deal. Many mortgages start with a higher charge in the first year, with the percentage gradually reducing as the deal period moves closer to its end.
Do all mortgages have early repayment charges?
No, many mortgages do not include Early Repayment Charges at all.
They are mainly found during the initial deal period of fixed, tracker or discounted mortgages. Once that period ends, borrowers can usually repay the mortgage or switch lenders without any ERC.
Can you avoid paying an Early Repayment Charge?
Often you can avoid an ERC simply by waiting until the mortgage deal period has finished.
Most lenders also allow some overpayments each year without penalties. As long as those payments stay within the permitted allowance, an early repayment charge normally will not apply. Most lenders also allow some overpayments each year without penalties. As long as those payments stay within the permitted allowance, an early repayment charge normally will not apply.
Is it ever worth paying an Early Repayment Charge?
In some situations it can still make financial sense.
If a borrower can switch to a much lower interest rate, the long-term savings on the new mortgage may outweigh the cost of leaving the current deal early.
Do early repayment charges apply when you sell your home?
Yes, they can if the mortgage is still within its deal period.
When a property is sold the mortgage normally has to be repaid as part of the transaction. If that happens before the fixed or discounted deal has finished, the lender may apply an early repayment charge.
Can you make overpayments without triggering an ERC?
Yes, in most cases you can.
Many mortgage deals allow borrowers to pay a little extra off the balance each year without any charge. As long as those overpayments stay within the lender’s allowance – often around 10% of the remaining balance – an early repayment charge usually will not apply.
Why Early Repayment Charges Are Something Brokers Look at Closely
When people choose a mortgage, the interest rate usually gets most of the attention. That is completely normal. What tends to get far less attention is how easy – or difficult – it might be to leave that deal later on.
This is where early repayment charges start to matter. A broker will normally look beyond the headline rate and check how the mortgage behaves if circumstances change. Things like overpayment limits, how ERCs reduce over time, and whether the mortgage can move with the borrower all play a part in that bigger picture.
The best mortgage brokers tend to approach things a little differently. Instead of looking only at the headline rate, they usually look at how the whole deal works over time. That means checking how early repayment charges are structured, how much overpayment is allowed each year and whether the mortgage can be moved to another property if the borrower decides to relocate.
These details can matter later on. A mortgage that looks competitive on paper may turn out to be quite restrictive if circumstances change and the borrower wants to switch deals early.
By comparing lenders across the market, a broker can help borrowers find mortgages that combine reasonable pricing with enough flexibility to handle changes in the future.
Thinking About Switching Your Mortgage Early?
Switching a mortgage before the deal ends can sometimes make sense, but early repayment charges can change the numbers quite quickly.
Before making a move, it helps to look at the figures properly. A mortgage adviser can show how the ERC works on your current deal and whether changing lenders would actually save money once the charge is taken into account.
