Remortgage Guide UK — Should You Switch?
Thousands of UK homeowners overpay each month by sitting on their lender’s SVR. Learn when and how to remortgage to secure a better deal.
A remortgage is the process of switching your existing mortgage to a new deal — either with your current lender (often called a product transfer or rate switch) or with a completely different lender. It is one of the most effective ways for UK homeowners to reduce their monthly payments, lock in a better interest rate, or release equity that has built up in their property over time. Despite the potential savings, millions of borrowers never get around to remortgaging and end up paying far more than they need to on their lender’s standard variable rate (SVR).
The best time to start thinking about a remortgage is around three to six months before your current deal expires. Most fixed-rate and tracker deals last two, three, or five years, and once they end you are automatically moved onto the lender’s SVR — which is almost always significantly higher than the rate you were paying. Even a difference of one percentage point on a £200,000 mortgage can add more than £100 a month to your payments, so acting before the switch happens is critical.
In this guide we cover the key reasons to remortgage, how to tell if you are on your lender’s SVR, what early repayment charges (ERCs) are and how they affect your timing, the step-by-step remortgage process from application to completion, how equity release works through remortgaging, and the costs you should budget for. Whether you are a homeowner looking to save money each month or an investor wanting to restructure your portfolio, this guide will help you make an informed decision.
When should you remortgage?
The most common trigger is the end of your current fixed-rate or tracker deal. Once that deal expires you land on your lender’s SVR, which is typically 1.5% to 3% higher than the rate you were paying. On a £250,000 mortgage that difference could cost you £200–£400 extra every month.
Other good reasons include: your property has increased in value (giving you a lower LTV and access to better rates), your income has risen and you want to borrow more, you want to switch from an interest-only mortgage to repayment, or you want to consolidate other debts into your mortgage at a lower overall rate. You might also remortgage to release equity for home improvements, a deposit on a second property, or to help a family member onto the property ladder.

Other good reasons to consider a remortgage include: your property has increased in value (giving you a lower LTV and access to better rates), you want to borrow more, switch rate type, or release equity.
Your property value has increased
- A higher property value means a lower LTV ratio, which can unlock significantly better interest rates and save you thousands over the term.
You want to reduce monthly payments
- Switching from an SVR to a competitive fixed or tracker rate can cut your monthly outgoings substantially, freeing up cash for other priorities.
You want to release equity
- Remortgaging for a higher amount than you currently owe lets you access the equity in your home for renovations, investments, or other major expenses.
You want payment certainty
- Moving from a variable rate to a fixed rate protects you against future interest rate rises, giving you a guaranteed monthly payment for the fixed period.
The SVR trap: why it costs you money
Your lender’s standard variable rate (SVR) is the default rate you revert to when your introductory deal ends. Unlike fixed or tracker rates, the SVR is set entirely at the lender’s discretion and can change at any time. Most SVRs in the UK sit between 6% and 8%, compared with competitive fixed rates that may be between 4% and 5.5%.
According to UK Finance mortgage market data, hundreds of thousands of UK mortgage holders are currently sitting on their lender’s SVR, often without realising it. Many assume their rate stays the same after the fixed period ends, or put off the paperwork involved in switching. The cost of inaction can be eye-watering over the remaining term of the mortgage.

SVR vs fixed rate on a £200,000 mortgage (25-year term)
| Fixed rate at 4.5% | SVR at 7.25% |
|---|---|
| Monthly payment: £1,111 | Monthly payment: £1,440 |
| Annual cost: £13,332 | Annual cost: £17,280 |
| Rate guaranteed for deal period | Rate can rise at any time |
| Total interest (2-year fix): £17,064 | Total interest (same 2 years): £28,176 |
Sitting on an SVR for just two years on a £200,000 mortgage could cost you over £11,000 more in interest than switching to a competitive fixed rate.
Early repayment charges explained
An early repayment charge (ERC) is a penalty fee your lender charges if you repay all or part of your mortgage before the introductory deal period ends. ERCs are typically between 1% and 5% of the outstanding loan balance, and they usually decrease each year you are in the deal. For example, a five-year fix might carry a 5% ERC in year one, reducing to 1% in year five.
On a £250,000 mortgage, a 3% ERC would cost you £7,500 — which could wipe out any savings from switching to a lower rate. This is why timing your remortgage to coincide with the end of your deal is so important. Most lenders allow you to apply for a new deal up to six months in advance, so you can have your new mortgage ready to start the day your current deal expires, avoiding both the ERC and the SVR.

Typical ERC costs on a £250,000 mortgage
Start your remortgage early
Most lenders let you apply for a new deal three to six months before your current one expires. This means you can lock in a rate now without triggering an ERC, and your new deal starts seamlessly when the old one ends.
The remortgage process step by step
Remortgaging is typically quicker and simpler than taking out your original mortgage, especially if you are not moving home. The process usually takes four to eight weeks from application to completion, though it can be faster with a product transfer to your existing lender.
You will need similar documentation to a new mortgage application: proof of income (payslips, SA302 forms for the self-employed), bank statements, ID, and details of your existing mortgage. A broker can handle most of the legwork and ensure you are comparing the full market rather than just your current lender’s retention deals.

How a remortgage works
- 01
Review your current deal
Check when your deal expires, your current rate, your outstanding balance, and whether any ERCs apply. Gather your latest mortgage statement.
- 02
Speak to a broker
A whole-of-market broker compares deals from 90+ lenders to find the best rate for your LTV, income, and circumstances. This is free at Clearview.
- 03
Submit your application
Your broker submits the application with supporting documents. The new lender arranges a property valuation (often free for remortgages).
- 04
Solicitor and legal work
A solicitor handles the legal transfer between lenders. Many remortgage deals include free legal work as part of the package.
- 05
Completion
The new lender pays off your old mortgage and your new deal begins. Your monthly payments change to reflect the new rate and term.
Releasing equity through a remortgage
If your property has increased in value since you bought it, or you have paid down a significant portion of your mortgage, you may have built up substantial equity. Remortgaging for a higher amount than your outstanding balance allows you to release some of that equity as cash, which you can use for home improvements, a deposit on another property, or other major expenses.
For example, if your home is worth £350,000 and you owe £200,000, you have £150,000 of equity (an LTV of 57%). You could remortgage for £250,000, which takes your LTV to 71% — still well within the best rate bands — and release £50,000 in cash. The key consideration is that you will be paying interest on the additional borrowing for the remaining mortgage term, so it is worth calculating the total cost of the released funds.
If your property has increased in value since you bought it, or you have paid down a significant portion of your mortgage, you may have built up substantial equity. Remortgaging for a higher amount than your outstanding balance allows you to release some of that equity as cash. Use our LTV calculator to check your current equity position.
Equity release example
Property value: £350,000. Outstanding mortgage: £200,000. Available equity: £150,000. If you remortgage for £250,000 (71% LTV), you release £50,000 in cash while staying in a competitive rate band.

Costs involved in remortgaging
While remortgaging can save you money in the long run, there are upfront costs to be aware of. Some lenders absorb many of these costs through fee-free deals, free valuations, and free legal work, but it is important to factor in all potential charges when comparing offers. A broker can help you weigh up a lower rate with higher fees against a slightly higher rate with no fees.
Common costs include the arrangement fee (typically £500–£2,000, can often be added to the loan), valuation fee (£150–£500, often waived), solicitor or conveyancer fees (£300–£1,000, often included free by the lender), and any early repayment charges on your existing deal. There is no stamp duty to pay when remortgaging because you are not purchasing a new property.
