What is a remortgage?

A remortgage is when you take out a new mortgage deal on a property you already own. This might be to replace an existing mortgage or to borrow additional money against the property.

You may be looking to remortgage for several reasons - you could be coming to the end of the initial rate on your current mortgage and want to move to a different deal with your existing lender. Or you might be looking to switch your mortgage to a new lender.

In both of these situations, the aim is usually to avoid going on to your existing lenders' standard variable rate (SVR) so you can make savings. This is because most lenders' SVRs are higher than the initial rate that comes with a new mortgage.

Other reasons to remortgage could include if you’re looking to borrow more on your mortgage to free up some cash for a home renovation or extension, or to help pay off some debts.

Whatever your motivation, remortgaging can be a great way of finding better mortgage terms or getting better interest rates and ultimately saving money on your mortgage payments.

How do remortgages work?

Simply put, remortgages switch your current mortgage deal to a new one. You'll use your existing property as security just as you did with your original mortgage deal. If you're looking to move homes and want to take your current mortgage deal with you, take a look at how to port your mortgage.

Our remortgages partner, Koodoo, can help you compare remortgage deals from a range of different lenders. These include high street banks and building societies like Santander, Nationwide and many more. If you're looking to remortgage, simply go through the application process. You'll then be able to compare and we'll help you find the best deal for your financial situation. Alongside each deal we clearly show the total cost of the initial period so it's easy to compare different deals. If you need more detail, you can also view and compare account rates, fees and incentives for each deal.

Why and when should I remortgage?

There are many reasons why you might want to remortgage:

  • Your current mortgage deal is coming to an end
  • Your variable rate mortgage has a high interest rate
  • You're not happy with your current lender
  • You'd like to start mortgage overpayments
  • The value of your property has increased
  • You'd like to borrow more on your mortgage

Your current mortgage deal is coming to an end so you'll be moved to the lender's standard variable rate (SVR). This rate is usually higher than your fixed rate deal. By remortgaging, you could find a new deal with a better interest rate.

Your variable rate mortgage has a high interest rate and a rise in the Bank of England's base rate could increase your mortgage payments. You could find a more competitive deal by remortgaging.

You're not happy with your current lender or with the level of service you're currently receiving. Choosing not to remortgage with your current lender means you're free to find a new one with better service and a better reputation.

You'd like to start mortgage overpayments but if your current deal doesn't allow or has restrictions on overpayments, you could find a remortgage deal that lets you start or increase your overpayments.

The value of your property has increased, and you'd like to see if you now qualify for better interest rates. If you're lucky enough to own a property that has increased in value, your new lower loan-to-value (LTV) could help you when applying for better interest rates when you remortgage.

You'd like to borrow more on your mortgage in order to get a lump sum to help consolidate debts, for some home improvement or for something else. You can remortgage to release some of the equity from your property.

If you're over 50 years old, you may be eligible for equity release.

How much can I borrow with a remortgage?

Lenders will only lend you as much as they believe you'll be able to pay back.

They work this out by looking into your financial situation - taking into account your income, expenses and your credit history to get the best idea of how much to lend you and how much you're borrowing relative to the value of your property.

What are the costs and fees of remortgaging?

The cost of remortgaging largely comes down to the interest rate that's set by your chosen lender. Lenders offer a number of different rates but the rate you get is decided by things like your personal financial situation, credit history and your home's loan-to-value rate (LTV).

Some of the fees that typically come up during the remortgaging process include:

  • A property valuation
  • Arrangement fees
  • Admin fees
  • Legal fees
  • Early repayment fees

A property valuation is often part of the remortgaging process. This is so the lender can decide if your home is worth the amount you're looking to remortgage for.

Arrangement fees are the fee for the mortgage product. Sometimes known as the product fee, they can cost up to a couple of thousand pounds. Some lenders may let you add the fee to the mortgage amount.

Admin fees may be charged to you by the lender for setting up your remortgage deal.

Legal fees might come up if you need to pay for a solicitor to take care of the legal side of things. For example, if you're looking to switch and remortgage with a different lender.

Early repayment fees are normally charged if you change mortgage products before the end of the introductory period. The bulk of charges will be taken up by this kind of fee.

Exit fees may have to be paid if your existing mortgage deal hasn't come to the end of it's term yet and you're ending it early. Depending on your mortgage deal, you might still make savings by remortgaging, even if there are exit fees.

Some lenders may offer free fees with a remortgage deal, but it's important to take into account all fees when working out if you'll save money overall with a new deal.

What types of remortgage deals can I take out?

Finding a remortgage deal is very similar to taking out your first mortgage. The most common types are:

  • Fixed rate mortgage
  • Tracker deal mortgage
  • Capped rate mortgage
  • Discounted mortgage
  • Offset mortgage

A fixed rate mortgage has a fixed interest rate for a set amount of time. Good for when you want to know exactly how much your mortgage payments will be every month. Fixed rate deals typically last between 2 and 10 years.

A tracker deal mortgage has variable rates that track the Bank of England’s base rate at a set percent just above theirs. Your payments rise and fall depending on how high or low the base rate is each month.

Capped rate mortgages are similar to variable rate mortgages. A capped rate mortgage ties your payments to how high or low the rate is every month. This type of mortgage differs slightly though as there is a limit on how high the rate can go. Perfect if you want to avoid high, unaffordable payments.

A discounted mortgage is another type of variable mortgage, but this offers a discounted rate on the lender’s SVR for the duration of the initial period. The difference between a discount mortgage and a tracker mortgage is that the discount mortgage has an interest rate that is a set percentage of the lender’s SVR. While the interest rate on a tracker mortgage is a set percentage on top of the Bank of England’s base rate.

An offset mortgage is a type of mortgage that can help to reduce the interest you pay by offsetting your savings against the balance or total amount of your mortgage.

How does the loan-to-value rate of my home affect remortgaging?

Different lenders may have different rates of interest, depending on how much of the value of the property you want as a loan.

Should I revalue my house before I remortgage?

You should only revalue your property if you’re changing mortgage lender. If you’re staying with your current lender, there’ll be no need for a valuation.

If you’re looking to borrow more against the value of your home, you might want to get it revalued to see if it’s increased in value.

Is there an age limit on remortgaging?

Different mortgage lenders will have different age limits, so it’s best to check with yours first if you’re thinking about remortgaging. Some may have an age limit for starting a mortgage, and others for when the mortgage term comes to an end. However, the most important consideration for remortgaging will be if your income is high enough to cover the monthly payments, just like with your first mortgage.

How long does it take to remortgage?

Remortgaging your home is usually faster than buying your first property. It could be even faster if you’re staying with your current lender and if you’re not looking to borrow extra.

If you’re switching to a new deal, be sure to start the remortgaging process early enough to move straight to your new deal. This means you won’t switch to your lender’s SVR - which is typically more expensive - when your current mortgage term runs out. As a rough guide, start looking around 14 weeks before your rate is due to end.

How can I improve my chances of being accepted for a remortgage?

If you choose to stay with your current lender, there usually won’t be any additional checks to be accepted for a new deal. If you’re looking to remortgage with a different lender, to improve your chances you should consider:

  • Paying your bills on time
  • Checking your credit report for any mistakes
  • Checking if you’re on the electoral register
  • Your debts - don’t build up too much debt or borrow more than you can afford
  • Your credit history and score - see if there are ways to improve your credit score
