Fixed-Rate Break Fees Explained — and Why Yours Might Be Zero
26 February 2026 · Mary Molloy Solicitors
The fear of a break fee keeps many people on uncompetitive fixed rates. Sometimes the fear is justified; often the actual quotation is a fraction of what was imagined, and in some rate environments it is zero. The only way to know is to ask — the quotation is free and does not commit you to anything.
What the law caps the fee at
For mortgages covered by the European Union (Consumer Mortgage Credit Agreements) Regulations 2016, an early redemption charge on a fixed rate cannot exceed the lender's actual funding loss, calculated on the basis set out in your mortgage documentation. In substance: the lender borrowed at fixed rates to fund your fixed rate, and the fee compensates its cost of unwinding that funding early.
Why the fee moves with market rates
The funding loss depends on the difference between interbank rates when you fixed and interbank rates now, applied to your balance for the remaining fixed period. If market rates have risen since you fixed, the lender can typically redeploy the funds at equal or better rates — and the fee is small or zero. If rates have fallen, the fee grows. This is why quotations are valid only briefly and must be refreshed near drawdown.
How to use this when switching
Get the written quotation before committing to a switch and include it in the switching costs line of the comparison. If the fee is large, the arithmetic may still work — or it may be worth waiting out the fixed period. If it is zero, the last objection to switching often disappears. Either way, decide on the actual number, not the feared one.
