Think carefully before securing other debts against your home. You may have to pay an early repayment charge to your existing lender if you remortgage and other fees may be payable. Your home may be repossessed if you do not keep up repayments on your mortgage.

What is a remortgage?

If you are already paying a mortgage, switching to a new deal is called a remortgage. Your new mortgage is used to pay off your existing one.

For example, if your house is worth 200,000 and you have an outstanding mortgage of 100,000, you could get a new mortgage for 100,000. This would be used to pay off the old one, and you can then start repaying your new mortgage instead.

Getting a new mortgage with a new lender or your current one could save you money if you are able to get a deal with a lower interest rate.

When can you get a remortgage?

You can switch your mortgage deal at any time but you may have to pay fees.

If you have a fixed, discount, tracker or capped mortgage, you will get a promotional interest rate for a specific number of years.

If you pay off your mortgage before that deal ends you will usually have to pay an early repayment charge. This applies whether you clear the balance yourself or get a remortgage.

When the promotional term ends, your lender will usually put you on their standard variable rate (SVR), which is normally higher. You could switch after then to avoid the higher interest rate and because you will not usually have to pay the early repayment charge.

You can also remortgage if you want to move to a new fixed rate deal for the security of an interest rate that will not increase for several years.

Should you remortgage?

It is worth getting a remortgage if the amount you can save is more than how much you have to pay in fees.

How much does it cost?

You will have to pay:

  • Fees for paying off your old mortgage: You may pay an early repayment charge and an exit fee of 50 to 200.

  • Fees that come with your new mortgage: These include application fees charged by the lender, solicitor fees for the searches you need and survey fees* charged by your lender for valuing the property.

*However, you may not need to have a full survey when you remortgage if you had a home buyer's report or a full structural survey completed when you bought your home.

Here is everything you need to know about all of the fees charged on mortgages.

How much are early repayment charges?

Early repayment charges are usually a percentage of the amount you owe. Some charge a flat rate like 4%. On a 50,000 remaining balance, that would come to 2,000.

Other lenders charge a higher percentage the longer you have left on your mortgage. For example, a five year fixed mortgage could charge:

  • 5% if you pay it off in the first year (2,500 on a 50,000 balance)

  • 4% in the second year (2,000 on a 50,000 balance)

  • 3% in the third year (1,500 on a 50,000 balance)

  • 2% in the fourth year (1,000 on a 50,000 balance)

  • 1% in the final year (500 on a 50,000 balance)

You can check the costs on your mortgage statement, in your terms and conditions or by asking your lender for a redemption statement. This will confirm how much you owe and what fees you need to pay to clear the balance.

How much can you save?

If you can get a new mortgage with a lower interest rate you could pay:

  • Less overall because the total amount of interest you pay will fall

  • Lower monthly repayments

For example, if you had an outstanding balance of 130,000 and 20 years left on a mortgage with 4% interest, it could be cheaper to switch to a fixed rate deal with 2.5% interest. You could pay:

MortgageInterest rateMonthly paymentCost over 5 years
Current deal4%78847,280
New fixed rate2.5%68941,340

How to decide

If you want to get a remortgage to save money, make sure the new lower interest rate is not cancelled out by fees.

Work out how much money you will save with a cheaper mortgage and subtract the fees to find out how much better off you will be with a new mortgage.

For example, with a balance of 130,000, 20 years left and 3% interest, it could be cheaper to switch to a fixed rate deal with 2.5% interest if fees were 500. You could pay:

MortgageInterest rateCost over 5 years Cost with fees
Current deal3%43,26043,260
New fixed rate2.5%41,34041,840

How to get a remortgage

  1. 1.

    Check how much your property is worth - this guide explains how.

  2. 2.

    Check how much you owe on your mortgage by asking your lender for a redemption statement or by checking your mortgage statement or online account.

  3. 3.
  4. 4.

    Find a new deal through our remortgage comparison table or use a mortgage broker.

  5. 5.

    Make sure you will still save money by remortgaging even after you have paid all the fees on your old and new mortgage.

  6. 6.

    Check that you can afford the new mortgage you choose.

  7. 7.

    Apply for the new mortgage. When it completes, your solicitor will arrange the transfer of the funds to pay off your old mortgage.

Here is everything you need to know about buying a home, including getting your home valued and appointing a solicitor.

How long does it take?

Getting a remortgage usually takes between four and eight weeks. It can take longer if there are any complications like an application being rejected.

The process is likely to take longer if you switch lenders instead of getting a new deal with your current mortgage company.

If you want your new deal to start when your current one expires, start the process at least two months before.

Will you be able to remortgage?

When you apply for a remortgage, your new lender will decide whether to accept you based on the same criteria as getting a brand new mortgage.

Each lender has different requirements, but they will look at your income, current financial situation and your credit record.

Here is how lenders work out if they think you can afford a mortgage.

What happens to your current equity?

Mortgages let you borrow a percentage of a property's value, which is called its loan to value (LTV). A lower LTV usually means you can get a lower interest rate.

You can often get a better deal because the amount you borrow is usually a smaller percentage of your property's value than when you got your first mortgage.

For example, if you originally bought your home for 200,000 with a 90% LTV mortgage, your mortgage would have been for 180,000 (the other 10% would be covered by a 20,000 deposit).

If you have now repaid 80,000 of your capital and have 100,000 left to pay, your new LTV would be 50%, assuming your home is still worth 200,000.

You should be able to find a much cheaper mortgage with a 50% LTV than with 90%. This means building equity in your property can save you money whenever you remortgage.

Your LTV will be lower still if your property has gone up in value since you got your last mortgage.
