Fixed Rate Remortgage

How Fixed Rate Mortgages Work

A fixed rate mortgage locks in your interest rate for a specified period. During the fix, your monthly payment stays exactly the same regardless of what happens to the Bank of England base rate, swap rates, or the wider economy. At the end of the fix, you revert to the lender's standard variable rate (SVR) unless you remortgage or arrange a product transfer with your existing lender.

Fixed rates available in the UK in 2026 come in five main lengths:

• 2-year fix — the most popular option, gives a short commitment with the lowest fixed rates in most markets
• 3-year fix — a useful middle ground, less commonly offered
• 5-year fix — increasingly popular, offers longer certainty and often similar rates to 2-year deals
• 7-year fix — offered by a handful of lenders, niche but useful if you want medium-term certainty
• 10-year fix — lifetime-style security, typically with higher rates and higher ERCs

Lenders price fixed rates using swap rates rather than the Bank of England base rate. Swap rates reflect what lenders can borrow money for over that period in the wholesale market, and they can move significantly day-to-day based on inflation data, economic news, and central bank guidance. This is why fixed mortgage rates sometimes change even when the base rate has not.

Typical Fixed Remortgage Rates in 2026

Fixed rates in April 2026 reflect a 4.50% Bank of England base rate and moderately elevated swap rates. Typical remortgage rates look like this:

LTV	2-Year Fix	5-Year Fix	10-Year Fix	Typical Fee
60%	4.39% — 4.69%	4.29% — 4.59%	4.79% — 4.99%	£999 — £1,499
75%	4.54% — 4.89%	4.44% — 4.74%	4.89% — 5.14%	£999 — £1,499
85%	4.79% — 5.19%	4.64% — 4.94%	5.09% — 5.39%	£999 — £1,499
90%	5.04% — 5.49%	4.89% — 5.29%	5.34% — 5.69%	£999 — £1,999
95%	5.59% — 6.09%	5.39% — 5.89%	n/a	£0 — £999

The cheapest 5-year fixes are currently 0.10-0.20% lower than the cheapest 2-year fixes, which is a reversal of the historical norm. This reflects market expectations that base rate will drift down over the medium term, so lenders can price longer fixes slightly more aggressively.

Rate Reservation and Timing Your Application

Most UK lenders let you reserve a new fixed rate up to six months before your current deal ends. This is a valuable feature because it means you can lock in today's rates even if swap rates rise between now and your switch date.

The standard timeline

1. 6 months before deal end — start shopping. Get broker quotes, compare direct deals, run numbers
2. 4-5 months before — submit application and reserve the rate
3. 2-3 months before — valuation, underwriting, and mortgage offer issued
4. 1 month before — conveyancer finalises paperwork
5. Deal end date — new fix starts, no gap on SVR

If swap rates fall between reserving your rate and completion, many lenders will let you switch to a cheaper rate from their range, but the rules vary. HSBC, Barclays, and Santander are generally more flexible on this; others are stricter.

If you miss the window and slip onto the SVR, even for one month, you could pay hundreds of pounds more than necessary. At typical SVR of 7.50-8.00%, a £200,000 mortgage on SVR costs around £500-600 more per month than a competitive fixed rate.

Early Repayment Charges on Fixed Rates

Fixed rate deals almost always include early repayment charges (ERCs). These compensate the lender if you repay or remortgage before the fix ends. The ERC is typically a percentage of the outstanding balance that tapers down each year:

Typical 5-year fix ERC structure:

• Year 1: 5% of outstanding balance
• Year 2: 4%
• Year 3: 3%
• Year 4: 2%
• Year 5: 1%

On a £250,000 mortgage in year 3 of a 5-year fix, the ERC would be £7,500. This is substantial, which is why it rarely makes sense to break a fix early unless rates have fallen dramatically.

Most fixed rate products allow you to overpay up to 10% of the outstanding balance each year without triggering an ERC. This is useful if you want to chip away at the balance without committing to a new product.

A handful of lenders (including First Direct on some deals) offer fixed rates with no ERCs, but these usually come with higher headline rates.

Pros and Cons of a Fixed Rate Remortgage

Pros

• Payment certainty — your payment cannot change, which makes budgeting straightforward
• Protection from rising rates — if the Bank of England raises rates, you are insulated until the fix ends
• Rate reservation — you can lock in today's rates up to 6 months ahead
• Wide availability — every major UK lender offers competitive fixed rates, so the market is deep
• Portable — most fixes let you transfer the mortgage to a new property if you move during the fix

Cons

• No benefit if rates fall — if the Bank of England cuts rates, you still pay the fixed rate
• Early repayment charges — expensive to exit early
• Product fees — arrangement fees are typically £999-£1,999, which can erode the savings on smaller loans
• Need to remortgage again — at the end of the fix, you must remortgage or slip onto SVR

How to Choose the Right Fix Length

Fix length comes down to your plans, your attitude to risk, and the rate differential between terms.

Choose a 2-year fix if:

• You think rates will fall significantly in the next 2 years and you want to remortgage to a cheaper deal sooner
• You may move or repay in the next 2-3 years
• The rate gap between 2 and 5-year fixes is large enough to justify shorter-term certainty

Choose a 5-year fix if:

• You value long-term payment certainty
• You are unlikely to move or repay in the next 5 years
• The 5-year rate is similar to or lower than the 2-year rate (as in 2026)
• You want to minimise the number of times you remortgage (saving on fees each cycle)

Choose a 10-year fix if:

• You want maximum long-term certainty
• You are confident you will not move, repay, or need flexibility for a decade
• You are comfortable paying a small premium for that certainty

Product Transfer vs Full Remortgage for a Fix

When you come to the end of your current deal, you have two main routes into a new fixed rate: a product transfer with your existing lender, or a full remortgage to a new lender.

Product transfer means staying with your current lender and accepting one of their new-deal rates. The paperwork is minimal — often just a few clicks online — and there is no need for a new valuation, conveyancer, or hard credit search. Most product transfers complete in 1-2 weeks. The downside is that you are limited to your lender's own range, which may not include the best rates in the market.

Full remortgage means moving to a new lender. This gives you access to the entire UK market, typically hundreds of products, so you can choose the genuinely cheapest rate and most suitable features. The process takes 4-8 weeks, includes a full underwrite, a property valuation, and conveyancing (usually free as part of the remortgage package).

A broker will usually check both options. If your existing lender's best rate is within 0.15% of the cheapest market rate, and the market saving over the fix period is less than £1,000-£1,500, a product transfer is often the sensible choice. If the gap is bigger, full remortgage typically wins.

Many borrowers remortgage every cycle to keep pressure on their existing lender to offer competitive retention rates. Switching is free for most borrowers (free valuation, free legal work included in most remortgage deals), so the only real cost is the arrangement fee on the new product.

Stress Testing and Affordability

When you apply for a fixed rate, lenders will stress-test your affordability at a higher assumed rate. The purpose is to check you could still afford the mortgage if rates rose significantly by the end of the fix. Typical stress rates in 2026:

• 2-year fix: tested at product rate + 3%, or SVR + 1%, whichever is higher
• 5-year fix: usually tested at the product rate itself (no uplift, because the rate is locked for 5 years)
• 10-year fix: tested at product rate only

This is why 5-year fixes often allow larger borrowing than 2-year fixes on the same income. If you are stretching on affordability, a 5-year fix can genuinely increase your borrowing capacity.

Lenders will also assess your committed outgoings: existing credit, loans, car finance, childcare, school fees, and council tax. A typical UK lender will allow 4-4.5x your gross annual income as the maximum loan, but some (Halifax, Barclays, Nationwide) stretch to 5-5.5x for high earners.

Fees, Cashback and Incentives

Fixed rate deals typically come with one or more of these fees and incentives:

• Arrangement fee — £0 to £1,999, payable on completion or added to the loan
• Booking/application fee — £99 to £199, payable at application, non-refundable
• Valuation fee — £0 to £500, though most remortgage deals include a free valuation
• Conveyancing fee — £0 to £800, though most remortgages include free legal work
• Cashback — £250 to £1,000, paid on completion

Choosing the right fee structure depends on your loan size. On a small mortgage (£80,000), a £999 arrangement fee is equivalent to over 1% of the balance, which can wipe out the saving from a slightly lower rate. On a large mortgage (£400,000), the same fee is 0.25% and barely matters compared to the rate.

Always compare total 5-year cost (interest + fees) rather than headline rate alone. A 4.29% rate with a £999 fee on £200,000 costs slightly more than a 4.34% rate with a £499 fee over the first 2 years — the break-even depends on your balance.
