In a nutshell

Remortgaging to release equity is when you take out a larger mortgage to unlock some cash that was tied up in your house. You can then use this cash for whatever you want!


Own a property? Want some extra cash in your pocket? You may want to remortgage to release equity. Here, we’ll take a look at what that means, why you might want to do it and how to go about it.

What is remortgaging to release equity?

Remortgaging is where you take out a new mortgage on a property you own. If you’re a homeowner, then chances are you’ll want to do this at some point or other – usually to get a better deal, reduce your monthly repayments or shorten the length of your mortgage (known as your mortgage term).


Remortgaging to release equity, on the other hand, is when you remortgage to get some cash. By taking out a new, bigger mortgage that covers more of the value of your property, you reduce the amount of equity you own and get some of the money you once put into the property back in cash.

What is equity?

Equity refers to how much of your property you own outright. Basically, even though you do own your house when you buy it, if you haven’t paid off your mortgage, you still owe the mortgage lender a proportion of your house’s value. 

Let’s imagine you sell your house and don’t buy a new one. The equity is the amount that will go straight into your pocket. The rest of the property’s value will go back to your mortgage lender in order to pay off the loan.

Most of the time, the equity you have in your property will go up. This is for two reasons:

  1. As time passes, you’ll usually pay off more of the loan, which means more of the property will be yours outright.
  2. Your house will probably increase in value.

The more equity you have in your house, the easier it is to remortgage to release it.

Why remortgage to release equity?

The problem with equity is that a proportion of your wealth is tied up in your property. This is essentially money that you own but you can’t spend.

Imagine this, for example: you own a lovely house but you don’t have the spare cash you need to replace your boiler, pay for your child’s uni fees or build an extension. How frustrating!

One thing you could do to get that cash is sell your house. But what if you don’t want to?

That’s where remortgaging comes in.

If you remortgage to release equity, you get to buy whatever it is you’ve set their heart on – without having to sell up. 

A lot of people use this as a way to make improvements to their home. For example, they might use the money to knock down walls, build an extension, renovate a bathroom… the list goes on. This can be a really smart thing to do as making home improvements could add value to your house – giving you more equity in the long run! Is it just us with dollar signs in our eyes right now?!

What’s the catch with remortgaging to release equity?

Remortgaging to release equity might sound like the best thing you’ve ever heard of. Especially if you’ve got your eye on something special that you don’t have the cash for.

But watch out: it’s not all sunshine and roses. So, weigh up the pros and cons carefully before making a decision.


  • Keep hold of your house: If you need cash and the only way you can get hold of it is by releasing equity, remortgaging will allow you to do so without selling your house.
  • Pay for home improvements: Releasing equity could give you the cash flow you need to carry out home improvement projects, like building an extension. This could add value to your home and so increase the equity you hold in the long run.
  • Pay off debts: Mortgages usually have lower interest rates than bank loans, credit cards and other kinds of loans. So, you might want to remortgage to pay off other debts. Just watch out because you’ll probably end up paying more interest overall if you spread these repayments out over a longer period.

  • Increase your loan: Remortgaging to release equity will increase the size of your loan. This means you’ll end up paying more interest overall.
  • Reduce your equity: Watch out that you don’t reduce the equity you have in your property by too much. House prices can occasionally go down, and you don’t want to end up with a loan that’s larger than the value of your property, known as negative equity. This could make it hard to remortgage or move home in future. 
  • Get a worse rate: If you drastically reduce your equity, you may end up falling into a lower loan-to-value bracket (to do with how much you’ve borrowed in comparison to the amount of equity you own). This could mean you end up with a worse deal than your current one.
  • Early repayment charges: If you remortgage while you’re in the fixed rate period of your mortgage, you could face an early repayment charge, which could be thousands of pounds. You might also have to pay other fees to cover the admin involved.

How much equity do I own?

If you’re wondering how much cash you could get by releasing equity, the first thing you’ll need to find out is how much equity you actually own!

You can get a rough idea of how much your home is worth by looking at what other, similar properties have sold for in your area. The Land Registry can help you out here, but you can also get some information from sites like Rightmove.

Alternatively, why not just get an estate agent to come over and give you an estimate? Most will do this for free, as they’re hoping that you’ll sell your house and use them as your estate agent. Be careful though: some estate agents will inflate their estimations as a way of getting you to pick them. It’s usually best to get a few estimates so you build up a clearer idea of how much your home is really worth.

Now you’ll need to subtract the amount you still owe your lender (your outstanding mortgage amount) from the amount that your property is worth. That’s how much equity you own. Simple!

How much equity could I release from my home?

Ideally, you’ll want to steer clear of remortgaging to release equity unless you have a decent amount of equity built up in the property. This is because if you dramatically change your loan-to-value ratio (the amount you’ve borrowed in comparison to the equity you own), you could end up paying a lot more interest.

If you own your entire property outright then now’s when you get to act smug. Usually, this will give you access to the very best deals (check out our piece on remortgaging when you own your house outright for the full lowdown).

Some mortgage lenders have calculators available on their websites that can give you an estimate of how much equity you could release. However, it’s always best to speak to a mortgage broker for advice. They’ll be able to give you an idea of what the different lenders are looking for. Plus, they’ll guide you through the whole remortgaging process. What more could you want?!

How long does it take to remortgage and release equity?

It normally takes around 4 to 8 weeks to get the funds after you’ve submitted an application to remortgage. So, make sure you start the process nice and early, particularly if you need the cash for something specific!

How long does a remortgage take?

Wondering why it takes so long to remortgage and release equity? Well, your lender will need to check your finances and credit score to work out what kind of deal they’re willing to offer you, just like they did when you first took out your mortgage. 

That’s just one reason why getting a mortgage broker involved is the way to go. They can give you a picture of how strong your application is before you go to your lender. That way, you’ll know what to expect and you can avoid wasting time on applications that are likely to get rejected.
