Quick Answer: When you remortgage to release equity, you take a new (and larger) mortgage on your existing property, receiving the difference as cash. Many UK lenders let you borrow around 75% to 85% of a property's value. The most common reasons behind such remortgages include home improvements, debt consolidation, and BTL investments.

What remortgaging to release equity really means

Equity is the value you own in a property after deducting your outstanding mortgage.

For example, suppose you purchased a property in London 8 years ago. At the moment, you owe £180,000 out of the total property price £420,000. So, your equity in the house will be £240,000.

Now, suppose you need an additional £40,000 for a loft conversion; you can remortgage and use the raised equity without taking out a separate loan.

This is what remortgaging to release equity is all about. It replaces your existing mortgage with a larger one, letting you encash the equity earned so far.

Considering the UK property trends, homeowners are likely to have built more equity than they realise. If necessary, they can release it with the right remortgage with the same lender or a new one.

How much equity can you release?

Generally, you cannot borrow against all of your equity. Most UK lenders limit borrowing to around 75% to 85% loan-to-value (LTV). This depends on the property, borrower, and purpose of releasing equity.

The approval also depends on whether you continue with the same lender or switch to a new one. Existing lenders are likely to be more lenient with affordability and valuation. However, take a expert mortgage broker's help to explore deals from new lenders based on your requirements.

Which properties qualify for remortgaging to release equity?

The properties qualifying for such an arrangement depend on whether specific lenders consider remortgage for equity relese.

Standard residential homes across the UK generally have broader access to lender markets. For example, a Victorian terrace or a conventional semi-detached property can give you suitable lender options for remortgaging.

However, here are the properties most UK lenders put restrictions on when it comes to raising equity-while remortgaging:

Ex-local-authority flats
Flats above commercial premises
Leasehold properties with short remaining leases
Properties with unusual construction types

It is important to note that cladding is no longer a barrier for properties qualifying for such mortgages. EWS1-cleared buildings are now accepted by many lenders across the UK.

Why do UK homeowners remortgage to release equity?

Some of the common reason for remortgage are:

Home improvements

Remortgage for home improvements is the most common purpose behind remortgages with additional funds. Homeowners often take out new mortgages for extensions, loft conversions, kitchen renovations, bathroom improvements, and related fixes. Known as Remortgage for home improvement.

Debt consolidation

Many homeowners also raised equity when remortgage to consolidate their debts. If you have multiple spread-out debts and they are getting difficult to manage, you can take a single loan to consolidate them. However, this may change some of your unsecured debts into a debt secured against your property. This means that you may lose your home if you do not keep up with mortgage repayments.

Buying another property

Remortgage to release equity helps many homeowners buy new residential property or invest in buy-to-let properties across the UK. Funds can be use as a deposit for purchase or to buy property outright.

How much does remortgaging to release equity cost?

When you release equity through a remortgage, you increase your overall monthly repayment and total interest. This is because you take a bigger mortgage to earn the balance as profit.

The most common costs associated with such a mortgage include:

Product or arrangement fees: £999 to £1,999
Valuation fees: can be free if you work with the same lender or some offer free valuation.
Legal costs: £300 to £800 but some cases this is paid by lender.
Early repayment charges: depending on the lender, if you end a deal too soon before expiry of the fixed mortgage term.
Broker Fees: Most mortgage broker charge broker fee when remortgaging to release equity. But Fee Free Mortgage Broker can save you broker fees.

Remember that your LTV may rise after releasing equity. If you move to a higher LTV band, the new mortgage deal can come with a higher interest rate.

When does remortgaging to release equity not make sense?

Releasing equity is not always the best financial decision. It is viable only if you really need additional funds without taking out a separate loan.

High early repayment charges (if applicable) should be a major warning sign before you finalise your decision. As this can be in 1% or more of the outstanding mortgage amount.

Consider what you are borrowing for.

Remortgaging to release equity will extend your overall mortgage and keep you in debt for longer. Go ahead with your plans only if you have the bandwidth.
