How to find the best 3-year fixed rate mortgage
The table above is sorted by interest rate, which is the right place to start but the wrong place to stop. The cheapest headline rate on a 3-year fix frequently carries a product fee of £999–£1,499, and on a smaller loan that fee can wipe out the saving entirely. A deal at 0.15% higher with no fee often works out cheaper over the 3 years.
The honest comparison is total cost over the deal period: the monthly payments you'll actually make for 3 years, plus every fee you pay to get the deal, minus any cashback. Two products with the same rate can differ by four figures once fees, valuation costs and legal work are counted.
Three-year fixes are the thinnest part of the fixed-rate market, so the usual assumption — that more competition drives keener pricing — doesn't hold as reliably here. Always price a three-year deal against the two- and five-year alternatives before committing; the middle option is not automatically priced in the middle.
Check the APRC, then ignore it
APRC assumes you keep the mortgage for its full term and roll onto the lender's standard variable rate afterwards. Almost nobody does that. It is useful for spotting a deal with hidden costs, not for ranking deals you intend to switch away from.
Confirm the loan-to-value band
Rates are tiered by LTV. A product advertised at a headline rate may only be available up to 60% LTV — the same lender's 85% product will be priced noticeably higher.
Match the buyer type
Lenders price the identical product differently for a first-time buyer, a home mover and a remortgage. Use the selector above the table so you're comparing rates you could actually be offered.
Why the 3-year market is smaller
Lenders fund fixed-rate mortgages by buying interest-rate swaps of a matching length. The two-year and five-year swap markets are deep and liquid; the three-year market is less so. That funding reality, plus much lower borrower demand, means many lenders simply don't offer a three-year product, and those that do often price it closer to their five-year deal than their two-year one.
The practical effect is that your choice is narrower. You may find that the lenders offering the sharpest three-year rates aren't the ones you'd otherwise consider, or that the best three-year deal available to you sits at a specific LTV band you don't quite fit.
When three years is the right answer
The genuine case for a three-year fix is a known date. If you can name the thing that changes your situation — a fixed-term contract ending, a child starting school in a particular town, an inheritance or bonus that will let you overpay substantially, a plan to move in about three years — then matching the fix to that date is sensible and specific.
The weaker case is hedging. Choosing three years because you can't decide between two and five is a reasonable instinct, but it isn't a hedge in any meaningful sense: you're still fully exposed to whatever rates do at the end of it. If you genuinely can't decide, compare the total cost of each over the same horizon and let that break the tie.
Fees matter more on a shorter deal
A product fee is amortised over the life of the deal in your head, even though you pay it up front. Spread a £1,499 fee over five years and it's £25 a month; spread it over three and it's £42. On a £200,000 mortgage, a fee-free deal only needs to be about 0.25% cheaper over three years to beat that fee — a gap that shows up regularly.
Adding the fee to the loan makes the up-front cost disappear but not the cost itself. You pay interest on it for the remaining term of the mortgage, which on a 25-year term can more than double what the fee actually costs you.
Common questions
What is a 3-year fixed rate mortgage?
Your interest rate is locked for three years. Payments cannot change during that window, and at the end you revert to the lender's standard variable rate unless you switch to a new deal.
Why do so few lenders offer 3-year fixes?
Partly funding — the three-year swap market lenders use to hedge fixed-rate lending is less liquid than the two- and five-year markets — and partly demand. Most borrowers instinctively pick two or five years, so there's less commercial reason to maintain a full three-year range.
Is a 3-year fix a compromise between 2 and 5?
On commitment length, yes. On price, not necessarily — three-year deals are often priced nearer the five-year end. It's worth treating it as its own option and comparing total cost properly rather than assuming it splits the difference.
What early repayment charges apply to a 3-year fix?
Typically a tapering percentage of the outstanding balance, often around 3% in year one falling to 1% in year three, though this varies by lender. Check the specific product's terms — the taper and the size vary far more between lenders than the headline rates do.
How current are the rates on this page?
We collect product data from the lenders we track from their published information and refresh it regularly, so the three-year deals listed above are the most recent we've seen from these lenders. Lenders can withdraw or reprice a deal at any time, sometimes with a few hours' notice, and a rate shown here is not an offer — availability depends on your circumstances, the property and the lender's own criteria.
