Loan-to-value is one of the quiet numbers that can make a big difference when you remortgage. It affects how a lender views the risk of the loan, which products may be available, and sometimes the rate you are offered. Two homeowners with similar incomes and credit histories can see different options simply because one has more equity in the property.
Your remortgage loan to value is not fixed forever. It changes as you repay the mortgage, make overpayments, borrow more, or as your home’s value rises or falls. Understanding the ratio before you apply can help you decide whether to wait, reduce the balance, or adjust how much equity you want to release.
What does loan-to-value mean when remortgaging?
Loan-to-value, usually shortened to LTV, compares the amount secured against your home with the property’s current value. Divide your outstanding mortgage balance by the property’s value, then multiply by 100.
If your home is valued at £300,000 and you owe £210,000, your mortgage loan to value is 70%. That means roughly 30% of the property’s value is equity before allowing for selling costs or other secured borrowing.
A remortgage lender normally works from the value it accepts for the property, not simply the figure you hope the home is worth. That valuation can therefore change the LTV used for your application.
Why a lower LTV can widen your options
A lower LTV gives the lender a larger equity cushion if the property later has to be sold. That generally makes lower-LTV borrowing less risky. Homeowners with more equity may therefore have access to a wider selection of remortgage products and, in many cases, more competitive pricing.
LTV is not the only test. Lenders can also consider income, regular expenditure, credit history, mortgage term, property type and the borrowing requested. A strong remortgage LTV does not automatically overcome affordability or eligibility issues elsewhere.
How LTV bands work in the UK
Mortgage lenders often group products into LTV bands rather than pricing every percentage point separately. Common market thresholds can include levels around 60%, 75%, 80%, 85%, 90% and 95%, although the exact bands and maximum LTV depend on the lender, product and applicant.
This is why moving from just above a lender’s threshold to just below it can matter. A borrower at 76% LTV may not qualify for the same product range as someone at 75%. When comparing LTV bands UK homeowners should look at actual lender criteria rather than assuming every provider uses identical cut-offs.
A practical threshold example
Suppose your home is valued at £320,000 and your mortgage balance is £244,000. Your LTV is 76.25%. Reducing the balance to £240,000 would bring it to exactly 75%. That does not guarantee a better deal, but it shows why checking the numbers before applying can be worthwhile.
If you are considering an overpayment, first check any early repayment charge or overpayment limit on your current deal. Our guide to mortgage overpayments can help you weigh the potential saving against the value of keeping cash available.
Property value can move your LTV in either direction
Homeowners often focus on the mortgage balance, but the property’s value matters just as much. If your mortgage falls from £200,000 to £190,000 while your home rises from £250,000 to £280,000, your LTV falls from 80% to about 68%. That can materially change the products you are eligible to consider.
The reverse is also possible. If property values fall, your LTV can rise even while you keep making payments. A large fall can leave a homeowner with very high LTV or negative equity, where the mortgage exceeds the property’s value, making a switch to a new lender more difficult.
Online estimates are useful for planning, but the figure that matters for a remortgage is the valuation accepted by the lender. If it comes in lower than expected, ask what evidence the lender may consider if comparable local sales or substantial improvements support a higher figure.
Releasing equity changes the calculation
If you remortgage and borrow extra money, calculate LTV using the new total mortgage balance, not what you owe today. For example, a £168,000 mortgage on a £240,000 home gives a 70% LTV. Increasing the loan to £180,000 raises the ratio to 75%.
Borrowing beyond that would push the LTV above 75%, potentially placing the application in a different product band. Our guide to releasing equity when remortgaging explains the wider trade-offs, including the effect of spreading extra borrowing over a long mortgage term.
Ways to improve your LTV before applying
If your ratio is close to a useful threshold, confirm your latest mortgage balance, get a realistic property value and calculate how much you would need to repay to reach the next band. If an overpayment is affordable, compare the potential mortgage saving with the benefit of retaining an emergency cash buffer.
Reviewing your options before your current deal ends gives you time to check the likely valuation, your credit file and the difference between a new lender and a product transfer. Our mortgage affordability checks guide can help you prepare for the wider assessment.
Do not judge a remortgage on LTV alone
A lower LTV can improve your position, but the cheapest headline rate is not automatically the cheapest remortgage. Product fees, valuation or legal costs, cashback, early repayment charges and the length of the new deal can all affect the total cost.
Compare what you are likely to pay over the period you expect to keep the mortgage, not just the advertised rate.
Frequently asked questions
What is a good LTV for remortgaging?
There is no single best LTV. Lower ratios generally give lenders more security and can widen product choice, but the useful threshold depends on current lender criteria and your wider application.
Can I remortgage at 90% LTV?
Some lenders offer high-LTV remortgage products, but availability varies. Eligibility also depends on factors such as affordability, credit history and the property, so check current criteria rather than assuming a 90% option will always be available.
Does my LTV automatically fall as I repay the mortgage?
Repaying capital reduces the balance and can lower LTV if the property value stays the same. However, a fall in the property’s value can offset some or all of that improvement.
Which property value is used for a remortgage?
The lender uses the valuation it accepts for the application. This may come from an automated valuation, a remote assessment or a physical inspection, depending on the lender and property.
Making LTV work in your favour
Loan-to-value is one of the clearest numbers you can calculate before comparing remortgage deals. Check your balance against a realistic property value, then see whether you are close to a lender’s pricing threshold. A small reduction in borrowing can sometimes open more options, while releasing equity can move you into a higher band.
Use LTV as a starting point rather than a verdict. A sound remortgage decision combines a sensible equity position with affordability, suitable product features and a comparison of the full cost of switching.
