Remortgage UK 2026: when to remortgage, how it works and what it costs

Mortgages

Remortgaging is the process of switching your mortgage to a new deal, either by staying with your existing lender on a new fixed or variable rate (a product transfer) or by moving the mortgage to a different lender entirely. Most UK homeowners with a fixed-rate mortgage need to remortgage at the end of the fixed period to avoid reverting to the lender's Standard Variable Rate (SVR), which is almost always significantly higher than the fixed rate and can increase your monthly payments substantially.

The UK remortgage market is one of the largest in the world by volume, reflecting the prevalence of relatively short-term fixed rate deals of two and five years rather than the long-term fixed rates common in other countries. In 2026, millions of homeowners face the transition from low pandemic-era fixed rates to significantly higher current rate deals, making the remortgage decision one of the most financially significant choices many households will make this year. This guide covers how remortgaging works, the cost implications, and what to compare.

Product transfer vs full remortgage

When your fixed rate period ends, you have two main options: a product transfer with your existing lender, or a full remortgage to a new lender. A product transfer is simpler: your existing lender offers you new deals from their current range, and if you accept, the switch happens without a full application process, credit check, or legal work. This is faster and has no legal costs, but you are limited to your existing lender's product range, which may not be the most competitive in the market. A full remortgage involves applying to a new lender, which includes a credit check, income verification, and property valuation, and usually requires using a solicitor for the legal transfer. In return, you access the full market and may secure a better rate. Many lenders offer free legal services and free valuations as remortgage incentives, making the process less costly than it sounds. The FCA's consumer duty requires lenders to inform customers about available options, including the product transfer, before their deal expires.

When to start comparing remortgage deals

Most lenders allow you to lock in a new deal up to six months before your current fixed rate expires, without paying an early repayment charge. Starting your comparison four to six months before the expiry date gives you enough time to assess the market, apply for a new deal if switching lenders, and complete the legal process before your existing rate ends. If you wait until your fixed rate expires and revert to the SVR, you pay a higher rate for every month that passes until you complete the switch. Given current SVR levels, even a two-month delay in switching can add hundreds of pounds in unnecessary interest costs. Set a calendar reminder six months before your fixed rate expiry date and begin comparing at that point.

Early repayment charges and when they apply

Early repayment charges apply if you switch from a fixed rate mortgage before the fixed period ends. ERCs are typically expressed as a percentage of the outstanding loan balance and decline over the fixed period: for a five-year fix, a common structure might be 5% in year one, 4% in year two, 3% in year three, 2% in year four, and 1% in year five. On a £200,000 outstanding balance, a 3% ERC is £6,000. Before switching early, calculate whether the saving from moving to a lower rate outweighs the ERC cost over the remaining fixed period. This calculation is called the break-even analysis: if switching saves £300 per month and the ERC is £6,000, the break-even point is 20 months. If you have less than 20 months remaining on the fix, switching early may still make sense; if you have more, staying until the fixed period ends is typically better value.

Remortgaging to release equity

Some homeowners remortgage to release equity from their property - borrowing more than the outstanding balance - to fund home improvements, pay off other debts, or for other purposes. This is called a capital raising or further advance remortgage. The additional borrowing increases the loan-to-value ratio, which may move you into a higher rate band. Lenders will re-underwrite the full mortgage at the increased amount, including a new affordability assessment. Releasing equity through remortgaging is a significant financial decision: the additional borrowing is secured against your home, so failure to maintain payments risks repossession. The FCA's MCOB rules require lenders to carry out a full affordability assessment for any increase in borrowing, and to consider whether remortgaging is in the customer's best interest under the consumer duty.

Remortgaging costs: what to budget for

A product transfer with your existing lender typically has no legal or valuation costs, though a product fee (also called an arrangement fee) of £500 to £1,500 may apply for lower-rate products. Some lenders offer fee-free rates at a slightly higher interest rate as an alternative. For a full remortgage with a new lender, costs can include: a valuation fee (£150 to £1,500 depending on property value and lender, though many offer free valuations for remortgage applicants); legal fees for the conveyancer handling the transfer (£500 to £1,000, often covered by cashback from the new lender); a product arrangement fee (£0 to £2,000, sometimes added to the mortgage); and a broker fee if using a mortgage broker (typically £300 to £600, though many brokers are fee-free and earn from lender procuration fees). Compare the total cost over the initial fixed period - monthly payment plus all fees - rather than comparing rates in isolation.

Frequently asked questions

What is the standard variable rate and why should I avoid it?

The SVR is the interest rate your lender charges after a fixed, tracker, or discounted rate deal ends, if you do not actively choose a new deal. SVRs are set by individual lenders and are typically significantly higher than fixed rate alternatives - often 7-9% in 2026, compared with fixed rates available from 4-5%. There is no obligation to stay on the SVR; you can switch to a new deal at any time without an ERC once your fixed period has ended.

Do I need a solicitor to remortgage?

For a full remortgage with a new lender, yes. A solicitor or licensed conveyancer handles the legal transfer of the mortgage charge from the old to the new lender. Most lenders offering remortgage deals provide free legal services through a panel conveyancer, which removes this cost from the process. For a product transfer with your existing lender, no solicitor is required as the security remains with the same lender.

Can I remortgage if my property value has fallen?

Yes, but a lower property value means a higher LTV, which may push you into a more expensive rate band or restrict which lenders will consider your application. If your LTV has risen above 90% or 95% due to a fall in value, options are limited. Speak to a mortgage broker who can access the full market and identify lenders that may still offer competitive rates for your LTV. Your existing lender may offer a product transfer without a new valuation in some circumstances.

Can I remortgage to a longer term to reduce my monthly payments?

Yes. Extending your mortgage term during a remortgage reduces monthly payments but increases the total interest paid over the life of the loan. Lenders will assess affordability at the new extended term. There is no regulatory restriction on extending terms, provided the lender is satisfied the loan remains affordable and the term does not extend significantly beyond state pension age for the borrowers. Consider the long-term cost of a term extension alongside the short-term payment reduction before proceeding.

Is it worth using a mortgage broker to remortgage?

A whole-of-market mortgage broker accesses deals from across the market, including products not available directly to consumers, and can compare hundreds of products quickly. They can also advise whether your existing lender's product transfer offer is competitive. Many brokers earn commission from lenders and charge no direct fee to borrowers. For straightforward remortgages, direct comparison via lender websites and comparison tools is also effective. For more complex situations - adverse credit, unusual income, or high LTV - a broker's expertise is more valuable.
