Further Advances on Your Mortgage Explained

Edited: February 2026

A further advance on your mortgage is one option to consider if you need to borrow additional funds. Instead of replacing your existing mortgage, a further advance allows you to borrow more from your current lender while keeping your original loan in place.

For some borrowers, this can be a practical and cost-effective solution. In particular, it may suit those who want to avoid early repayment charges or who already hold a competitive mortgage rate. However, a further advance is not always the best option, and alternatives should be considered carefully.

This guide explains how further advances work, when they are appropriate, and what to consider before proceeding. It is written by the specialist mortgage team at GPS Financial, who regularly advise homeowners and landlords on mortgage restructuring and additional borrowing.

What Is a Further Advance?

A further advance is an additional loan taken with your existing mortgage lender. It is secured against your property and runs alongside your current mortgage rather than replacing it.

In most cases, lenders charge a higher interest rate on a further advance than on the original mortgage. Even so, this type of borrowing is often cheaper than unsecured options such as personal loans or credit cards.

Because the borrowing is secured, lenders carry out affordability and credit checks. As with any secured borrowing, your property is at risk if you fail to keep up repayments.

What Criteria Do You Need to Meet?

Although criteria vary by lender, having sufficient equity in your property is essential.

Equity is the difference between your property’s value and the outstanding mortgage balance. For example, if your home is worth £300,000 and your mortgage balance is £200,000, you have £100,000 in equity.

Most lenders cap total borrowing at around 85 percent loan to value. Using the example above, this could allow a further advance of approximately £55,000, subject to affordability.

In addition, lenders often require:
• A minimum further advance amount, commonly around £10,000
• A minimum loan term, typically two years
• Your existing mortgage to have been in place for at least six months
• Satisfactory affordability and credit checks

Because limits and requirements differ, taking advice before making assumptions is important.

What Can a Further Advance Be Used For?

Borrowers commonly use further advances to:
• Raise a deposit for a second property, including Buy to Let or holiday homes
• Fund home improvements or renovations
• Consolidate existing debts into a single monthly payment
• Release funds for major life events such as weddings or university fees

However, it is important to assess whether a further advance is the most cost-effective solution. In some cases, remortgaging or alternative borrowing options may better suit your rates, fees, and long-term plans.

Advantages and Disadvantages of a Further Advance

A further advance can be attractive if you want to keep your existing mortgage deal, especially where early repayment charges make remortgaging expensive.

Potential advantages include:
• No need to replace your existing mortgage
• Often cheaper than unsecured borrowing
• Useful where early repayment charges apply

However, there are also disadvantages to consider:
• The additional borrowing is secured against your home
• Missed repayments place your property at risk
• Longer loan terms can increase the total interest paid

For this reason, debt consolidation using secured borrowing should always be approached with caution and fully understood before proceeding.

How Long Does It Take to Receive the Funds?

Most lenders require confirmation that you have received mortgage advice before releasing funds.

Timescales vary, but in many cases it takes around six to eight weeks from approval for funds to be released. Delays can occur where valuations, underwriting, or documentation require further review.

What Are the Alternatives to a Further Advance?

Depending on your circumstances, alternatives may include:
• Remortgaging to a higher loan amount
• A second charge mortgage
• Equity release, where appropriate
• A personal loan
• Using savings or investments

Each option involves different costs, risks, and suitability considerations.

Frequently Asked Questions

Is a further advance the same as a remortgage?
No. A further advance adds borrowing with your existing lender and runs alongside your current mortgage. A remortgage replaces your mortgage with a new one.

Are further advance rates higher than my current mortgage rate?
Often, yes. However, they are usually cheaper than unsecured borrowing.

Can I use a further advance for Buy to Let purposes?
Some lenders allow this, but criteria vary. Advice is essential, particularly where funds support property investment.

Does a further advance affect my existing mortgage deal?
No. Your original mortgage remains in place. The further advance has its own rate and conditions.

Is my home at risk with a further advance?
Yes. Because the borrowing is secured, missed repayments could lead to repossession.

How much can I borrow with a further advance?
This depends on your property value, existing mortgage balance, lender loan-to-value limits, and affordability.
