Remortgaging is replacing your current mortgage with a new one from a different lender, often when your deal is ending or you're looking for a different rate.

What is a remortgage example?
Sarah's mortgage deal has ended and she's now on her lender's Standard Variable Rate (SVR), which is higher than the rate she was paying before. She has £150,000 left on her mortgage and is paying £950 a month.
She shops around and finds a lower-rate mortgage with a different lender. After remortgaging, her monthly payment reduces to £850 a month, saving her £100 each month.
By changing to a new mortgage rate, Sarah could save money compared to staying on the SVR.
How to remortgage
Before you start the remortgage process, there are a few steps to follow to make sure remortgaging is right for you.
-
1
Find out what your property is worth
Your new mortgage provider will need to know how much your current property is worth. You could find out an estimated value using online valuation tools or asking an estate agent to provide a valuation (some estate agents may charge for this service).
If you decide to remortgage with NatWest, we will obtain our own valuation which may differ from other valuations obtained.
-
2
Check how much is left to pay
Look at your last mortgage statement to see how much is left to pay on your current mortgage. This can be used as a guide to know how much you need to borrow for your next mortgage.
-
3
Apply for an Agreement in Principle (AIP)
Once you’ve compared mortgages and found the right one for you, you can get a mortgage AIP which will give you an indication of what we could lend you based on your remortgage requirements.
-
4
Compare our remortgage rates and deals
Just enter a few details into our mortgage rate finder to find out how much your monthly repayments might be. It only takes a few minutes and it could help you decide how much you would like to borrow.

Check all remortgage costs
When considering all remortgage options, consider any additional costs that may be associated with the remortgage process:
- Interest rates vs product fee: Understand the total remortgage costs, for example, considering a higher interest rate without a product fee vs a lower interest rate with a product fee.
- Valuation fee: This is to confirm the property value. The cost will range depending on the value of the property.
- Broker fee: If you use a broker to help you remortgage, they should let you know if they charge a fee or if it’s a fee-free service.
If you remortgage to NatWest
If you move a mortgage to us from another provider, we'll pay your valuation and legal costs (exclusions apply).

Apply for your mortgage
Now that you have an AIP, you could be ready to apply for your remortgage. There are a few documents you’ll need to provide such as, proof of ID, proof of income, financial circumstances (loans or credit commitments) and current mortgage details.

Final step for completing a remortgage
The lender will carry out various checks to verify your current circumstances and will arrange for the property to be valued to enable the remortgage product to be approved.
Getting prepared to remortgage
You can view and compare the rates you may be eligible for by completing an Agreement in Principle. It’s a personalised indication of what we could offer you.
Alternatively, you can arrange to speak to a mortgage professional to help discuss your options. Contact us if you need help with your mortgage.
The following steps can help you understand your current situation and needs before applying for a remortgage.
1. Look out for exit or repayment fees
Unless you're at the end of an existing mortgage deal, you may have to pay an Early Repayment Charge (ERC) depending on your current mortgage terms and conditions. Check your paperwork for an ERC, if you're unsure, contact your mortgage provider to get the details.
These fees are also something to consider when looking for your new mortgage.

2. What do you need from your next mortgage?
Depending on your situation and needs, the lowest interest rate may not always be the best option.
For example, you might find that a more flexible mortgage with a higher interest rate that allows you to easily exit the mortgage, is better suited for you.
If you're unsure, you can always speak to a mortgage professional to understand your options.

3. Check your credit score
As the lender will be making a credit check to assess your circumstances, it can be beneficial to review your credit score. This will ensure there are no mistakes in your credit history and check if there are any quick wins that may help improve your score, before submitting your mortgage application.
