Financing home improvements: considering your options

Home improvements can be a practical way to improve comfort, energy efficiency and property value. For many homeowners, the question isn’t whether they can afford the work, it’s how to finance it in a way that fits their current mortgage position.

This guide compares your funding options. For more detail, see:

• Further advance mortgages, for a detailed look at the further advance product itself.
• Secured loans and second charge mortgages, for how a separate secured loan works.
• Remortgaging to release funds, for comparing a full remortgage with other ways to raise funds.

If you already have a mortgage, there are two borrowing routes that often come up:

• A further advance (additional borrowing with your current lender)
• A second charge loan (additional borrowing secured against your home with a different lender)

Understanding how each option works, what it can cost, and what risks to consider can help you choose the most suitable approach.

Further advance: borrowing more from your existing mortgage

A further advance is additional borrowing from your current mortgage lender, secured against the same property.

How it typically works

• You request extra funds without switching your existing mortgage.
• The additional borrowing is assessed using factors similar to those used for the original mortgage decision, such as affordability, credit profile, and available equity.
• The further advance is added to your existing mortgage relationship with the lender (for example, as additional borrowing under the same overall arrangement).

Why homeowners consider it

A further advance can be attractive when you want to:

• Avoid early repayment charges that may apply if you remortgage or move lenders
• Keep the benefits of your current mortgage arrangement (for example, if you’re part-way through a fixed-rate period)
• Borrow within your existing lender’s framework

Key points to consider

• Repayment planning matters: because the borrowing is secured on your home, you’ll need to be confident you can meet the repayments.
• Timing and flexibility: if your current mortgage term ends before the further advance is fully repaid, it may affect how the overall borrowing is managed in the future.
• Lender criteria still apply: even if you’re an existing customer, the lender will still review whether you can borrow more.

Second charge loans: additional borrowing secured on your home

A second charge loan is a separate loan secured against your property, taken out with a new lender. It sits behind your existing mortgage in terms of security, meaning your current mortgage is the first charge, and the additional loan is the second charge.

How it typically works

• You keep your existing mortgage in place.
• A second lender provides additional funds secured against the property.
• The second charge is typically set up as a separate agreement with its own terms and repayment schedule.

Why homeowners consider it

A second charge loan may be considered where:

• Your current lender is not able or willing to offer additional borrowing
• Your circumstances have changed and you no longer meet the current lender’s borrowing requirements
• You want to avoid moving your existing mortgage, particularly if you have a rate you want to keep or you’re part-way through a fixed period

Key points to consider

• It’s still secured borrowing: if you can’t make repayments, the risk to your property remains.
• You may need consent: taking out a second charge typically requires permission from your existing mortgage lender.
• Costs can differ: second charge products often have different pricing and fee structures compared with further advances.

Comparing further advances and second charge loans

Both options can provide funds for improvements, but they can differ in how they’re assessed, priced and managed. It can be helpful to consider how each route may affect future decisions, such as:

• whether you may want to remortgage later
• how changes in income or expenses could affect affordability
• how the overall borrowing structure might be handled if you sell the property

Other factors that influence your borrowing options

When planning home improvements, lenders will often look beyond the project itself. Common considerations include:

• Property value and equity: the amount of borrowing available can depend on how much equity you have.
• Affordability: lenders assess income, outgoings and existing commitments.
• Credit profile: borrowing decisions can be influenced by credit history.
• Loan structure and term: the way the borrowing is set up can affect monthly payments and total cost.
• Fees and charges: product fees, arrangement costs and any relevant charges can change the overall affordability.

Choosing the right route for your circumstances

There isn’t always a single “best” option, what works depends on your current mortgage position, your borrowing needs and your ability to manage repayments.

In many cases, starting with the option that keeps you with your existing lender can be beneficial, particularly if you’re trying to avoid switching your mortgage part-way through a fixed period. If that isn’t available, a second charge loan can be an alternative route to access funds while leaving your existing mortgage in place.
