The nasty surprise usually arrives when you think you have found a better mortgage deal. You check your current mortgage, spot a lower rate elsewhere, then see the small print: an early repayment charge. So, can I remortgage with early repayment charge? Yes, you can – but whether you should is a completely different question.
This is where plenty of borrowers get caught out. A lower rate does not automatically mean a better deal. Lenders love a headline rate. What matters is the full picture: the charge for leaving early, any arrangement fees on the new mortgage, valuation or legal costs, and how long it will take to recover those costs through lower monthly payments. If you skip that maths, you risk moving too soon and paying for the privilege.
Can I remortgage with early repayment charge and still save money?
Sometimes, yes. Sometimes, absolutely not. It depends on the size of the charge, how much you still owe, how much lower the new rate is, and how long you plan to stay in the new deal.
An early repayment charge, often called an ERC, is a fee your lender applies if you repay all or part of your mortgage during a tie-in period. That tie-in period is usually linked to a fixed, tracker or discounted deal. The lender offered you terms on the basis that you would stay put for a set period. Leave early, and they charge you for it.
In the UK, ERCs are commonly a percentage of the outstanding mortgage balance. That might be 1 per cent, 3 per cent or even more, depending on the product and how far through the deal you are. On a mortgage balance of £200,000, a 3 per cent ERC is £6,000. That is not a rounding error. It is a serious cost, and it can wipe out the benefit of switching if you move at the wrong time.
The key question is not just whether you can remortgage. It is whether remortgaging now leaves you better off overall.
What an early repayment charge actually means
Borrowers often assume the charge is a penalty for bad behaviour. It is better to think of it as a contractual exit fee. It is written into the mortgage terms you agreed to when you took the deal.
That matters because there is no magic workaround just because the fee feels unfair. If your mortgage offer says the ERC applies until a certain date, the lender is entitled to charge it if you redeem the mortgage before then.
There are, however, details worth checking. Some products allow overpayments up to a set annual limit without triggering an ERC. Some only charge the fee during the initial deal period, after which you can switch freely. In some cases, the charge reduces each year. If you are close to the end of the tie-in, waiting a few months may save you thousands.
This is why guessing is expensive. You need the exact ERC amount, the exact end date, and the full cost of the replacement mortgage before making a move.
When paying an ERC can still make sense
This is the bit many banks will not spell out clearly. Paying an early repayment charge is not automatically a bad idea. If the savings from the new mortgage comfortably outweigh the cost of leaving early, it can be the right move.
A common example is someone stuck on a higher rate while market rates available to them are significantly lower. If their mortgage balance is large, even a modest rate drop can produce meaningful monthly savings. Over the next two, three or five years, those savings may more than cover the ERC and fees.
It can also make sense if your current deal is ending soon and your lender’s follow-on rate is poor, or if your circumstances have improved and you now qualify for a much better deal elsewhere. Some borrowers also remortgage early to raise capital for home improvements or to consolidate more expensive borrowing, though that needs careful advice because stretching debt over a mortgage term can cost more in the long run.
Then there are life changes. Divorce, moving home, a change in income, or the end of an interest-only strategy can all force a review. Mortgage decisions do not happen in a vacuum. The cheapest rate is not always the biggest priority if the current mortgage no longer fits your life.
When it usually does not make sense
If the ERC is large and the rate difference is small, the numbers often fail quickly. The same applies if you expect to move house again soon, repay a lump sum, or refinance in the near future. Paying one exit fee only to face another change shortly afterwards can be a costly chain reaction.
It may also be a bad idea if the new mortgage comes with chunky fees that wipe out the apparent saving. A deal with a lower interest rate but a high product fee is not automatically cheaper than a slightly higher rate with low fees. This is one of the oldest tricks in mortgage marketing. Borrowers see the rate and miss the total cost.
And if your credit profile has worsened since you took out the current mortgage, the best deals may no longer be available to you. In that case, remortgaging early can leave you paying an ERC for the privilege of landing on a mediocre new rate.
How to work out if a remortgage stacks up
Start with the hard numbers. You need your outstanding mortgage balance, your current rate, your ERC amount, your monthly payment, the date the charge ends, and the total fees on the proposed new mortgage.
Then compare the total cost of staying versus switching over a realistic period. That period should reflect how long you expect to keep the new deal. If you are comparing a five-year fix but plan to move in two years, using the full five years to justify the switch is not honest maths.
A simple break-even check helps. Add together the ERC and any new mortgage costs. Then estimate the monthly saving from the new deal. Divide the total switching cost by the monthly saving. That gives you a rough break-even point.
If the switching costs are £4,000 and the new mortgage saves you £200 a month, the break-even point is 20 months. If you will still be in the mortgage and on that deal beyond that point, the move may be worth considering. If not, probably not.
But do not stop there. You also need to consider whether the new rate is fixed or variable, whether affordability checks will be tighter, and whether your plans are stable enough to suit the product. Cheap and wrong is still wrong.
Can I remortgage with early repayment charge if I stay with my current lender?
Sometimes you can reduce the pain by looking at a product transfer with your existing lender. That means switching onto a new deal without moving the mortgage to a different bank or building society.
If your current deal is close to ending, this can be a simple route. In many cases, product transfers involve less paperwork and fewer underwriting hurdles than a full remortgage. But if you are still inside the ERC period, the charge may still apply. Staying with the same lender does not automatically exempt you.
The upside is that a product transfer can be useful if your circumstances have changed and a new lender might not offer you attractive terms. The downside is obvious: your current lender only offers its own products. That is not impartial advice. It is a menu from one kitchen.
The traps borrowers miss
The biggest trap is focusing on monthly payment alone. A lower payment feels good, but it does not tell you whether the deal is cheaper overall. Extending the mortgage term, adding fees to the loan, or shifting to interest-only can all lower the monthly figure while increasing the long-term cost.
Another trap is timing. If your ERC expires in a matter of weeks, paying it now may be pointless. Equally, if rates are moving fast, waiting may not save money if the best deals disappear before your charge ends. This is why broad rules do not work well in mortgages. The right answer depends on your numbers and your timing.
There is also the valuation issue. If your property has risen in value, you may drop into a better loan-to-value band and access stronger deals. If values have fallen, the opposite can happen. That can change the remortgage calculation significantly.
What to do before you make a move
Get your current mortgage statement and check the exact early repayment charge, not a rough estimate. Confirm the date it ends. Then compare whole-of-market options against the cost of staying put, not just the best advertised rate you can find online.
This is one of those moments where blunt, expert advice pays for itself. You need someone to look at the structure, not just the headline. Mortgage Genius helps borrowers cut through lender nonsense, compare the real cost of switching, and avoid expensive mistakes dressed up as bargains.
If the numbers support moving early, fine – move with confidence. If they do not, waiting can be the smartest financial decision you make this year. There is no prize for remortgaging quickly. The win is paying less overall and keeping control of the mortgage, instead of letting the mortgage control you.
