Fixed Rate Mortgages UK: What Brokers Actually Tell Clients in 2026

A fixed rate mortgage is the most popular product in the UK market, and it is also the one most people sign without understanding the trade-offs. Banks sell their own. Comparison sites push a calculator. Building societies publish 900 word definitions. Almost none of them tell you when you should not fix, what the swap market is doing to your rate this quarter, or how to think about early repayment charges in actual pounds.

This guide is the conversation a whole-of-market broker has with a client at the kitchen table. Direct, opinionated, and based on the May 2026 rate environment.

What Is a Fixed Rate Mortgage?

A fixed rate mortgage locks your interest rate for a set period, usually 2, 3, 5, or 10 years. Your monthly payment stays the same for the whole fixed term regardless of what the Bank of England does to the base rate.

When the fixed period ends, the deal does not. The mortgage continues, but it rolls onto the lender’s standard variable rate (SVR), which is almost always higher than what you were paying. The “term” of the fix is not the term of the mortgage. The mortgage itself usually runs 25 to 35 years; the fix is just the rate-protection window inside it.

What Is Driving Fixed Rates in May 2026

To understand the rate you are being quoted, you have to look at the market lenders actually buy money in. Fixed rate mortgages are priced off interest rate swaps (specifically SONIA swaps for 2-year and 5-year terms), not directly off the Bank of England base rate.

The April 2026 Monetary Policy Committee held Bank Rate at 3.75% with an 8 to 1 vote. CPI inflation came in at 3.3% for the year to March 2026, still above the 2% target. The next MPC decision is 18 June 2026, and markets are currently pricing a slow downward path rather than a fast cut.

What this means in practice:

• The average 2-year fix sits at 5.78% (Moneyfacts, 1 May 2026)
• The average 5-year fix sits at 5.68% (Moneyfacts, 1 May 2026)
• Both have fallen for three consecutive weeks as swap rates have softened
• Best buy rates for low loan-to-value borrowers are well below the average, often under 4.5%

If you are seeing higher numbers than this, you are either looking at high loan-to-value tier rates, specialist criteria, or older marketing material. Always check the date on any rate quote.

2 Year vs 3 Year vs 5 Year vs 10 Year: When Each One Is The Right Call

This is where most online guides hedge. They list pros and cons of each term and leave you to it. Here is the actual broker view.

2 Year Fix

Pick a 2 year fix when you think rates are going to fall meaningfully before your term ends. In May 2026, with the base rate at 3.75% and inflation easing, a 2 year fix gives you the option to remortgage onto a lower rate sooner. The downside is you pay arrangement fees twice in the same decade and your payment certainty is shorter.

3 Year Fix

The often-ignored middle option. Useful when you want a bit more certainty than a 2 year but think 5 years is too long to be locked in. Fewer lenders offer them, and pricing is usually similar to the 2 year, so they only make sense in specific scenarios. A broker who has run the numbers will tell you if it stacks up.

5 Year Fix

The right call when you want long-term payment certainty and you do not expect to need to overpay, move, or restructure within five years. Avoid the 5 year fix if you are likely to sell within three years, expect a major income change, or believe rates will be materially lower in two years. Locking in for five years and then trying to escape is expensive.

10 Year Fix

Rarely the right product. The premium you pay for that much certainty is significant, the early repayment charges run for the full decade, and life rarely cooperates with a 10 year plan. We almost never recommend them outside of very specific later-life or investment situations.

Worked Example: What A Fixed Rate Actually Costs

Numbers, not theory. Take a £250,000 repayment mortgage over a 30 year term. Using approximate May 2026 average rates:

• 2 year fix at 5.78%: monthly payment around £1,466. Total interest over 2 years approximately £28,000
• 5 year fix at 5.68%: monthly payment around £1,450. Total interest over 5 years approximately £67,500
• 10 year fix at typically 5.50%: monthly payment around £1,420. Total interest over 10 years approximately £128,000

Now compare to a best-buy rate at 60% loan-to-value, which can be closer to 4.30%. On the same £250,000 loan that is a monthly payment of around £1,238. Over 5 years you save more than £12,000 in interest compared to the market average. This is the difference between accepting your bank’s first offer and actually shopping the whole market.

Early Repayment Charges, Properly Explained

An early repayment charge (ERC) is what a lender takes if you exit a fixed rate before it ends. Almost every page online explains what an ERC is. Almost none show you the actual cost.

Typical ERC structures on a 5 year fix look like this:

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

On a £250,000 balance, a 3% ERC is £7,500. If you sell your house in year three of a 5 year fix and the mortgage is not portable, that is £7,500 gone before legal fees, valuation fees, and the cost of arranging a new mortgage on your next property. Most fixed rate mortgages are portable, which means you can take them with you to a new property, but porting is not automatic. It depends on the lender re-underwriting you against the new property.

If your circumstances might change in the next five years, the 5 year fix is not free certainty. It is certainty with a penalty clause.

What Happens When The Fixed Rate Ends

Your fixed term ends and three things can happen.

1. You do nothing. The mortgage rolls onto the lender’s standard variable rate. SVRs in May 2026 are typically between 7% and 9%. Your payment can jump by hundreds of pounds overnight.
2. You take a product transfer with the same lender. Quick, no affordability check in most cases, but you are only choosing from the rates that one lender offers.
3. You remortgage to a new lender. Full whole-of-market shop. Affordability assessed, but you get the cheapest rate you qualify for.

The lazy default is the product transfer. The lender emails you a button to click six weeks before your rate ends and most people click it because it feels simple. In a competitive market, a remortgage usually wins on rate even after factoring in valuation and legal costs. We cover this in detail in our product transfer vs remortgage guide and our what happens when your fixed rate ends walkthrough.

Fixed Rates For The People Lenders Ignore

Read any high street lender’s fixed rate page and they assume you are a permanent PAYE employee with three years of clean payslips. Most of the people we work with do not fit that template.

Self-Employed

The good news: most mainstream lenders will consider self-employed applicants on two years of accounts or SA302s. A growing number will accept one year. The bad news: high street computer-says-no systems are unforgiving. Specialist lenders use a broader view and accept retained company profit, day-rate contractors, and recent trading dips. Our self-employed first time buyer page goes into the criteria in depth.

Contractors

Day-rate contractors can often borrow on a multiple of weekly rate (day rate x 5 x 48) rather than on net profit. That is a much better outcome than being assessed on retained earnings. Not every lender does this. A broker will know who does.

Buy-to-Let

Fixed rate BTL deals are stress-tested on interest cover ratio (rent must cover the mortgage payment by a set margin, typically 125% to 145%). 5 year fixes use a more generous stress test than 2 year fixes, which is why a 5 year fix can actually let you borrow more on a BTL. This is rarely explained on lender pages.

Limited Company BTL

Lower stress tests, different tax treatment, but a smaller lender panel and higher rates. Worth the trade-off for higher-rate taxpayers in many cases. Tax advice required separately.

Adverse Credit

Defaults, CCJs, missed payments. The high street will reject you. Specialist fixed rate products exist and can be very competitive once the credit event ages. See our bad credit mortgage page.

Visa Holders

5% deposit fixed rate products are available to visa holders with at least 12 months remaining on their visa, and longer in some cases. The lender panel is narrow. Mainstream banks usually decline without explanation.

The Honest Case Against A 5 Year Fix Right Now

This is the section the lender pages will not write.

If you believe the base rate is going to fall to 3.25% or lower by mid 2027, and inflation continues to ease, a 5 year fix in May 2026 locks you in above where the market is likely to settle. You will sit on a 5.5% to 5.7% rate while new borrowers are taking 4% deals. You cannot just remortgage out because of the ERC structure.

The counter-argument is real. Markets price rate cuts into swaps quickly, so by the time the base rate falls the fixed rates available will already reflect it. And inflation has surprised forecasters in both directions for three years running. Locking in payment certainty has a value that is hard to quantify until you have lived through a payment shock.

Our view: in May 2026, a 2 year fix is the more flexible bet for most borrowers who can stomach reviewing their mortgage again in 2028. A 5 year fix is the right call for borrowers who want to forget about it and value certainty over chasing the optimum rate.

Why A Whole-Of-Market Broker Beats Fixing Direct With Your Bank

Your bank shows you their own rates. Their rates are sometimes the best on the market, often not. Even when the headline rate is comparable, the criteria are not. A whole-of-market broker has access to lender panels that the public never see, can place you with specialist lenders if your case is non-standard, and runs the affordability calculations across multiple lenders before submitting anything.

The cost of going direct is invisible. You never see the £4,000 of interest you would have saved over five years because you never knew the cheaper rate existed. Read our mortgage broker vs bank comparison for the full breakdown.

Scotland and Northern Ireland: A Quick Note

Most of the fixed rate market is UK-wide, but valuations work differently in Scotland (Home Reports rather than separate lender valuations in many cases), Land and Buildings Transaction Tax replaces Stamp Duty, and some lenders have narrower presence in Northern Ireland. The rate may be the same, but the timeline and process can differ. Worth flagging at the start of a case rather than discovering it at offer stage.

How To Compare Fixed Rate Mortgages Properly

The headline rate is one of four things that matter. Run any quote past these four:

• Rate (the obvious one)
• Arrangement fee (£0 to £1,999, and a low rate with a £1,500 fee can be worse than a higher rate with no fee)
• Cashback or free valuation (real money, treat as part of the deal)
• ERC structure and portability (the cost of needing to exit)

The “true cost” of a fixed rate over the term is the sum of monthly payments plus fees, minus cashback, plus expected ERCs if you might exit. A good broker quote shows all of this on one page.

Frequently Asked Questions

Is 4.5% a good mortgage rate?

In May 2026, 4.5% is a good rate for a borrower at 60% loan-to-value or below on a 2 or 5 year fix. At higher loan-to-value (85% and above), 4.5% would be a very strong rate. Always compare to the current market averages, not to historical lows.

Will interest rates drop to 3% again?

Not in 2026 based on current MPC guidance. CPI inflation at 3.3% is still above the 2% target. Most forecasters expect Bank Rate to fall gradually over 2026 and 2027 toward the 3% to 3.5% range, but a return to the 0.1% to 1% rates of 2020 to 2022 is not on the table.

What is the current rate for a fixed mortgage?

As of 1 May 2026, the Moneyfacts average is 5.78% for a 2 year fix and 5.68% for a 5 year fix. Best-buy rates at low loan-to-value are well below the average, sometimes under 4.5%. Your actual rate depends on loan-to-value, credit profile, property type, and lender criteria.

Can a 70 year old get a 30 year mortgage?

Not on standard high street criteria. Most mainstream lenders cap the mortgage end age at 70 or 75. Specialist lenders go to 85 or older, and Retirement Interest Only (RIO) products run for life with no end-age cap. The available terms shorten as the borrower’s age increases, and protection requirements change. Worth a specific conversation rather than a generic answer.

Can a fixed rate mortgage change during the fix?

The interest rate does not change during the fixed period. The monthly payment can change if you overpay (most lenders allow 10% per year without ERC), make a part-repayment, request a term change, or add or remove a borrower. The rate itself is locked.

Are fixed rate mortgages portable?

Most are. Porting means taking the same rate with you to a new property when you move. The lender re-underwrites you and the new property; it is not automatic. Always check the portability clause before you fix, especially if you might move within the fixed term.
