What Is an Offset Mortgage?

An offset mortgage is a type of home loan that links your savings and current accounts to your mortgage balance. Instead of earning interest on your savings, the lender uses that amount to reduce—or “offset”—the portion of your mortgage on which interest is charged. This can save you money over the life of your loan.

How Does an Offset Mortgage Work?

With an offset mortgage, your savings don’t directly reduce your mortgage balance, but they reduce the interest you owe. The lender calculates your interest payments based on the mortgage amount minus your linked savings. This means you’ll pay less interest overall while maintaining access to your savings when needed.

Example:

Mortgage balance: £300,000 

Savings account: £60,000 

Offset balance: £240,000 (the amount interest is charged on) 

Instead of paying interest on the full £300,000, you only pay interest on £240,000. This reduces your interest payments by 20%, resulting in significant long-term savings.

Who Is Eligible for an Offset Mortgage?

Anyone with savings can consider an offset mortgage. It’s particularly beneficial for: 

People with fluctuating or irregular incomes (e.g., freelancers, contractors, or self-employed individuals). 

Those who receive large bonuses or have lump sums of savings. 

Parents or families looking to help children with their mortgage costs.

Eligibility Criteria for an Offset Mortgage

Eligibility for an offset mortgage varies between lenders, but most follow similar requirements of most mortgage products. Here’s an overview of what will be considered.  

Savings Account: The account used for offsetting is often required to be held with the same lender. It must be a personal account, not a limited company account, and some lenders may set a minimum balance, often as low as £100. 

Deposit: Many lenders require a deposit of at least 20 or 25%. Lower deposit options may be available, but these may be limited to existing customers switching to an offset deal. 

Employment Type: Offset mortgages are available to both employed and self-employed applicants. Self-employed borrowers may need specialist advice but can qualify by providing proof of income. Some lenders also offer contractor-specific products. 

Affordability: Borrowing is typically calculated as a multiple of your disposable income, often between 4 and 5 times. You can get an idea of what you may be able to borrow below.

Advantages of offset mortgages

Save Money in interest: Offset mortgages reduce the amount of interest you pay over the life of the loan. 

Flexibility: Monthly mortgage payments can fluctuate based on how much is in your savings account. 

Immediate Access to Savings: Unlike paying a lump sum off your mortgage, your savings remain accessible for emergencies or other needs. 

Tax savings: While it’s important to note The Mortgage Pod does not offer tax or legal advice, offset mortgages can provide tax advantages. Instead of earning taxable interest in a savings account, your savings offset your mortgage, delivering a tax-free “return” through reduced interest costs. This can be especially beneficial for higher-rate taxpayers who would pay 40% or 45% tax on savings income.

Disadvantages of Offset Mortgages

Higher Deposit Requirements: Offset mortgages often require a larger deposit, typically 20-25% of the property’s value. 

Limited Options: Fewer lenders offer offset mortgages, which means less competition and fewer choices. 

Higher Interest Rates: These mortgages may come with slightly higher rates than standard repayment mortgages. 

Savings Tie-In: You may need to hold your savings with the same lender, limiting your options. 

Impact of Withdrawals: Taking money out of your savings account can reduce the amount offsetting your mortgage, which can increase your interest payments.

Can Parents Use Their Savings to Offset a Child’s Mortgage?

Yes, parents can use their savings to help reduce their child’s mortgage costs. This approach can be an excellent way for families to offer financial support without simply gifting their savings. By linking their accounts to a child’s offset mortgage, parents can lower the interest charged while still retaining access to their funds.
