The best time to remortgage is usually before your current mortgage deal ends, not after you have already moved onto your lender’s standard variable rate. For many UK homeowners, that means starting to review options around six months before the end date. This gives you time to compare your current lender’s offers with deals from other lenders, check the costs of switching, and avoid making a rushed decision.
There is no single date that works for everyone. Good remortgage timing depends on your existing rate, any early repayment charge, your loan-to-value ratio, your plans for the property, and the total cost of a new deal. A lower advertised rate can look attractive without actually making an immediate switch worthwhile.
Start reviewing your mortgage about six months before your deal ends
If you are on a fixed or discounted deal, put its end date in your calendar. MoneyHelper recommends shopping around at least six months before the deal reverts to the lender’s standard variable rate. Starting early does not mean you must switch immediately; it gives you time to understand your choices and prepare.
When a fixed-rate deal ends, borrowers are commonly moved to the lender’s SVR unless they arrange another product. An SVR is set by the lender and can change, so doing nothing may mean paying a higher rate than necessary.
Ask your existing lender what it can offer, then compare that with the wider market. Moving to another deal with the same lender is usually called a product transfer rather than a remortgage. When people look at mortgage renewal UK options, comparing both routes is useful because a product transfer can be simpler while a new lender may offer a more competitive overall deal.
Do not wait until the final week
A remortgage to a new lender can involve an application, affordability checks, a valuation and legal work. Leaving everything until the last minute creates unnecessary pressure and increases the chance that your current deal will end before the new one is ready.
When an earlier remortgage may be worth checking
If mortgage rates fall while you are still tied into a fixed deal, it can be sensible to run the numbers. The key is to include your early repayment charge, not simply compare the old and new interest rates. The FCA notes that borrowers leaving a fixed or discounted deal early may face an ERC, depending on their mortgage terms.
Also include product or arrangement fees, legal costs, valuation costs and adviser fees where applicable. The best time to remortgage is the point when the likely saving is greater than the cost and disruption of switching.
A practical example
Suppose you have eight months left on a fixed deal and find a lower rate elsewhere. Your monthly payment would fall, but your current mortgage has a sizeable ERC. If the saving over those eight months is smaller than the ERC and other fees, waiting may cost less. If the ERC reduces at a known date, that later point could be a better time to review again.
More equity can change your options
Your outstanding mortgage compared with your property value determines your loan-to-value ratio, or LTV. If you have paid down the balance or your home has increased in value, your LTV may have improved since you last arranged a mortgage. A lower LTV can sometimes give you access to a wider or more competitive range of products.
Your future plans matter as much as the rate
Remortgaging is not only a rate decision. If you expect to move home soon, a new fixed deal with a substantial ERC could reduce your flexibility. If your income has recently changed, you are newly self-employed, or you have taken on significant new credit commitments, a new lender may assess your application differently from your existing lender.
Compare the total cost, not just the headline rate
A common mistake is choosing the lowest interest rate without looking closely at fees. A slightly higher rate with a small fee can sometimes be better value than a lower-rate deal with a large arrangement fee, especially when the mortgage balance is smaller.
Compare expected repayments, fees paid upfront, fees added to the loan, ERCs, legal and valuation charges, and incentives such as cashback. If a fee is added to the mortgage, remember that you can also pay interest on that amount.
Useful related areas to review alongside this decision include remortgaging costs, fixed-rate mortgage end dates, and how loan-to-value affects mortgage rates.
Signs it may be time to review your mortgage now
A review makes sense if your fixed or discounted period has six months or less remaining, you are already on an SVR, your equity position has improved, your current deal no longer suits your plans, or the likely saving from switching appears comfortably greater than the costs.
If you still face a large ERC and there is no urgent reason to change, immediate switching may not make sense. You can still prepare by comparing deals and identifying the date when leaving your current mortgage becomes less expensive.
Frequently asked questions
How early should I start looking to remortgage?
Around six months before your current fixed or discounted deal ends is a practical starting point. It gives you time to compare your existing lender with other lenders and organise an application before the current deal expires.
Can I remortgage before my fixed rate ends?
Yes. You can remortgage before a fixed deal ends, but an early repayment charge may apply if the switch completes while that charge is still in force. Check your mortgage terms and compare the charge with the potential saving.
Should I remortgage as soon as interest rates fall?
Not automatically. Consider the ERC, product fees, legal and valuation costs, your outstanding balance and how long you expect to keep the new deal. A lower rate does not guarantee a lower overall cost.
Is remortgaging the same as renewing with my current lender?
No. Moving to a different lender is generally a remortgage, while choosing another deal from your existing lender is usually a product transfer. Comparing both options can help you find the better combination of cost, convenience and flexibility.
Choose the timing that works on the full numbers
For many homeowners, the strongest approach is to start reviewing the market about six months before the current deal ends. Earlier switching can sometimes work, but an ERC and other fees can quickly cancel out the apparent saving.
Before deciding, compare the total cost of staying versus switching and think about your plans for the next few years. Good remortgage timing is less about predicting the perfect rate and more about avoiding unnecessary SVR costs, understanding your fees, and choosing a mortgage that fits your finances.
