Remortgaging to release funds

Releasing equity means turning some of the value you’ve built up in your home into cash. For many homeowners, remortgaging is a common route because it uses the property as security, typically with regular monthly repayments.

This guide explains how remortgaging to release equity works, the main options available, and the factors that commonly influence how much you may be able to borrow.

What “equity” means

Equity is the difference between your property’s value and the total amount of debt secured against it.

A simple way to think about it:

• Property value (what the home is worth)
• Minus secured borrowing (your mortgage and any other loans secured on the property)
• Equals equity (the portion of value you effectively own)

If a home is worth £200,000 and you have £80,000 left on your mortgage, your equity is £120,000. If there is also a second charge (a further loan secured on the property), that second charge must be included when calculating total secured debt.

Negative equity: If the property value falls below the total secured debt, you may be in negative equity. In that situation, releasing equity is usually not possible because there isn’t enough value left after covering the debts secured on the home.

Releasing funds against your home: the main routes

A full remortgage, a further advance and a second-charge loan are different ways to borrow against home equity. Which route is most suitable depends on your current mortgage terms, your equity position, and whether the lender is comfortable with the purpose of the extra borrowing.

With a full remortgage to release equity, you typically:

1. Apply for a new mortgage (often with a different lender and/or deal).
2. The new mortgage is set at a higher amount than your current mortgage.
3. The new mortgage pays off your existing mortgage.
4. The difference between the new mortgage amount and your current balance is released to you as cash.

Borrowing more usually means higher monthly repayments, because you’re increasing the amount of capital you owe and paying interest over the mortgage term.

Full remortgage (swap your existing mortgage)

A full remortgage replaces your current mortgage with a new one. If you’re increasing the loan size, the extra borrowing can be used to release equity.

This route is often used when:

• you want to consolidate existing borrowing into one mortgage
• you want to change the term or repayment structure
• you’re aiming to release a larger amount of equity
• Your existing deal is nearing the end of its term
• You want to compare a wider range of rates and structures
• Your current lender’s further-advance terms aren’t competitive

A full remortgage can also be relevant if you need a different mortgage type or structure to support the borrowing you want.

Further advance (additional borrowing with your existing lender)

A further advance is an increase to your mortgage balance with your current lender.

Typical benefits include:

• You may be able to avoid switching lenders
• The process can be simpler in some cases

However, it still depends on whether your lender will agree to the additional borrowing and whether you can meet their criteria for LTV and affordability. For more detail, see the further advance mortgages guide.

Second charge / secured loan (keep your existing mortgage)

A second charge is an additional loan secured against the property, taken out alongside your existing mortgage.

This route may be considered when:

• you don’t want to replace your main mortgage
• you want to borrow against remaining equity while keeping your current mortgage in place
• your circumstances mean a full remortgage isn’t the best fit

If you have (or plan to have) a second charge on the property, the remortgage can be more complex. The new lender will need to understand the existing arrangement, and there may be additional legal work involved.

How much equity you can release

The amount you can raise depends on a combination of property value, how much equity you have, and how lenders assess affordability and risk.

Loan-to-value (LTV)

Most lenders use an LTV (loan-to-value) ratio, which compares the size of the loan to the property value.

• Lower LTV generally means less risk to the lender.
• Higher LTV usually means stricter checks and potentially different product availability.

Because your existing mortgage balance and any other secured loans reduce the equity available, LTV is often the starting point for what’s realistically possible.

Property value and equity available

Your remortgage amount is influenced by:

• the current value of the property
• the outstanding balance on your mortgage
• any other secured borrowing (including second charges)

If the property value is lower than expected, it can reduce the maximum loan size.

Affordability (income and outgoings)

Even if you have sufficient equity, lenders will still assess whether the repayments are affordable based on your financial circumstances.

Affordability is typically influenced by:

• your income (including how stable it is)
• your monthly commitments (credit cards, loans, existing mortgage payments, childcare costs, etc.)
• your credit history

Purpose of the loan

The reason you want to borrow can affect how lenders view the risk and, in some cases, the maximum loan size.

Commonly, lenders are more comfortable where the purpose is clearly linked to improving or securing the property, or where the funds are used in a way that doesn’t create unusual uncertainty.

Purposes that may be treated more cautiously include spending that could be harder to evidence or outcomes that depend on factors outside your control.

What can you use released equity for?

People release equity for a range of reasons. Common uses include:

• Home improvements: Extensions, renovations, repairs, and upgrades. In many cases, improving the property can help maintain or increase its value.
• Debt consolidation: Replacing higher-cost borrowing (such as credit cards or personal loans) with mortgage borrowing. This can reduce monthly outgoings for some borrowers, but it also changes the nature of the debt, because the borrowing becomes secured on your home.
• Large or planned expenses: For example, major purchases, weddings, or other significant costs.
• Supporting family: Some borrowers use equity to help family members, such as contributing to a deposit.
• Investing or business funding: This is sometimes considered, but it carries risk. Any investment plan should be assessed carefully, particularly if your mortgage repayments could become harder to manage.

For a closer look at one of these uses, see remortgaging to consolidate debts.

Worked scenarios (simplified)

These examples show the logic lenders often apply, though actual offers can vary depending on product rules, fees, and individual circumstances.

Borrowing against a mortgage-free property

• Property value: £420,000
• Outstanding mortgage: £0
• Potential borrowing based on LTV: up to 75% (illustrative)

A lender might consider a loan up to £315,000. If you’re using the borrowing to release equity, the cash you receive is the loan amount minus any costs and any amounts used to settle existing debts (if applicable).

For more on this scenario, see borrowing against a property you own outright.

Important considerations before you release equity

Releasing equity can be helpful, but it’s not always the right move. Consider the following points.

You’re increasing your debt

Even if the cash helps immediately, you’re taking on a larger mortgage balance. That means:

• higher monthly repayments, and
• paying interest on the additional borrowing.

Total interest can be significant

Extending borrowing over a longer term can increase the overall interest cost. The longer the term and the higher the amount borrowed, the more interest may accumulate.

Debt consolidation changes risk

If you consolidate unsecured debts into a mortgage, you’re effectively securing that borrowing against your home. If your circumstances change and you can’t keep up with repayments, the consequences can be more serious than with unsecured borrowing.

Early repayment charges (ERCs)

If you remortgage before your current deal ends, you may face early repayment charges. These can affect whether remortgaging now is financially worthwhile. Read more about early repayment charges and the cost of remortgaging.

Other fees and total cost

Additional borrowing doesn’t remove the usual remortgage cost considerations. The exact costs depend on your current deal and the route you take.

Some mortgages charge a product fee. If the fee is added to the loan amount, it can increase the total borrowing and the interest paid over time. There may also be product transfer fees or admin charges for further advances.

A lender will usually require a valuation before lending. Legal work is also typically needed for the mortgage completion and any changes to charges.

A careful comparison of the total costs, rather than focusing only on the headline rate, helps ensure the decision is based on the full picture.

Depending on your goals, unsecured borrowing may be more appropriate.

Factors that can affect approval or the loan amount

Even where you have equity, lenders may reduce the amount offered or decline an application based on additional risk factors.

Age

Many lenders have upper age limits for mortgage terms or at the point the loan must be repaid. Different lenders apply different rules, so it’s important to consider how your age affects the structure of the borrowing.

Employment and income type

Lenders generally want confidence that repayments can be maintained.

Income may be assessed differently depending on whether you’re employed, self-employed, retired, or receiving other income types.

Credit history

A less favourable credit profile can lead to:

• lower maximum borrowing
• higher scrutiny of affordability
• product restrictions

Remortgaging itself doesn’t automatically damage your credit record, but the process can involve credit-related activity.

Things that can affect your credit profile include:

• Missed payments on your current mortgage
• Multiple new credit applications in a short period
• Any changes to your financial circumstances during the application process

Keeping repayments on track and managing applications carefully can help reduce avoidable complications.

Reviewing your credit report can help you understand what lenders may see.

Size of the borrowing

Larger remortgages can involve additional underwriting checks and may require specialist products or different criteria.

Property type, condition, and location

Lenders may adjust the value they’re willing to lend against if the property is:

• non-standard construction
• in poor condition or requiring significant repairs
• in an area that increases risk (for example, flood risk)

The age and type of the property can influence valuation and lending appetite. If the property doesn’t meet typical lending standards, it may affect the maximum LTV.

If your application has been declined, an adviser can help you explore what may still be possible.

What the remortgage-to-release-equity process typically involves

While each case is different, the process often looks like this:

1. Review your current mortgage

   • Identify your end date and any early repayment charges.

2. Estimate your property value

   • Lenders will require a valuation; online estimates can help you form an initial view.

3. Work out what you need to borrow

   • Consider the amount required for your goal, and how that affects repayments.

4. Assess affordability

   • Lenders will check income, outgoings, and overall affordability.

5. Compare mortgage options

   • Deals can vary by term, interest rate type, and repayment structure.

6. Submit an application

   • Expect similar stages to a standard mortgage application.

7. Completion and funds released

   • The new mortgage repays the old one, and the released cash is paid to you (subject to the mortgage completion process).

When remortgaging to release equity may be a good fit

It can be more suitable when the released funds are likely to:

• improve the property (for example, works that add value),
• genuinely reduce overall costs (for example, consolidating debts where repayments become more manageable), or
• address a planned need where alternatives are more expensive or less practical.

When it may be less suitable

It may be harder to justify if:

• you’re likely to struggle with higher repayments,
• you’re concerned you may build up new unsecured debt after consolidation,
• the need is short-term and could be met in other ways,
• or you’re approaching retirement and future income may be more limited.

Remortgaging to release equity vs other options

Depending on your goals and circumstances, remortgaging may not always be the only route to access home value.

Some homeowners consider alternatives such as:

• equity release products designed for later life
• selling and downsizing to release equity without borrowing
• other forms of borrowing depending on affordability and property suitability

The right approach depends on your timeframe, repayment capacity, and how much flexibility you need. See equity release or remortgage and lifetime mortgages for more on later-life options.

Key takeaway

A remortgage to release equity can turn part of your home’s value into cash, but it also increases your mortgage balance and repayment commitment. The most important step is making sure the plan fits your budget now and in the future, and that you understand the costs and risks involved.
