Endowment mortgages were once one of the most popular ways to repay a home loan in the UK, particularly throughout the 1980s and 1990s. However, many borrowers later discovered their endowment mortgage policy might not generate enough money to fully repay the mortgage.
If you currently have an endowment mortgage or an existing endowment policy approaching maturity, understanding your options is crucial. Here, we’ll explain how endowment mortgages work, whether they’re still available in the UK, what to do if you face a shortfall, and how specialist mortgage advice can help.
What is an endowment mortgage?
It’s a type of interest-only mortgage linked to an investment policy known as an “endowment policy”. Instead of repaying the mortgage principal each month, borrowers pay only the interest to the lender.
Alongside this, separate monthly payments are made into the endowment policy, which is designed to grow over time and eventually repay the mortgage at the end of the term.
How do these mortgages work?
An endowment mortgage policy typically combines:
-
An interest-only mortgage
-
A life insurance policy
-
An investment or savings component
The idea was that the investment growth within the endowment policy would eventually repay the original mortgage balance and potentially produce a surplus (additional money on top).
However, the investment performance didn’t always meet expectations, leading many borrowers to face potential shortfalls.
Can you still get them in the UK?
They’re no longer widely available in the UK and are largely considered outdated compared to modern repayment mortgage products.
Most lenders stopped actively offering endowment mortgage products after widespread concerns about investment underperformance and mortgage shortfalls that emerged during the late 1990s and early 2000s.
Although new endowment mortgages are rare, there are lots of people in the UK who have older endowment policies that are still active or approaching maturity.
Steps to take if you have a shortfall on an endowment policy
If your provider has warned that your endowment policy may not fully repay your mortgage, it’s important to act early rather than waiting until the policy matures.
Here are some potential steps you can take to get ahead of any further issues:
-
Review your projected shortfall: Most providers issue regular projections showing whether your policy is on track to repay the mortgage balance. Understanding your estimated shortfall can help you assess how much action may be needed.
-
Speak with a mortgage advisor: An advisor experienced in endowment mortgage policies can review your current structure and remaining balance, and assess available repayment options to help reduce a potential funding gap.
-
Consider switching: Some borrowers choose to switch all or part of their mortgage onto a repayment basis to gradually reduce the outstanding balance before the endowment policy matures.
-
Make additional mortgage repayments: Depending on your lender’s terms, overpaying your mortgage could help reduce the amount you still owe when the endowment policy ends.
-
Review your investment strategy: In some cases, reviewing your endowment policy's investment performance with expert advice may help determine whether to keep or replace the current investment.
The earlier you address a projected shortfall, the more options you’ll find you have to reduce financial pressure later on.

FAQs
Typically, the investment policy matures and pays out its final value. This money is then usually used to repay the outstanding mortgage balance.
If the policy value is lower than expected, you may still owe the lender money and need to repay the remaining shortfall separately.
Yes, many borrowers choose to switch from an endowment mortgage to a repayment mortgage, particularly if their endowment policy is projected to fall short of repaying the outstanding balance.
Switching usually involves changing all or part of the mortgage from interest-only repayments to capital repayment, allowing you to gradually reduce the balance owed over the remaining mortgage term.
Possibly. Some borrowers may have taken out Payment Protection Insurance (PPI) alongside their mortgage or related financial products.
However, PPI was separate from the endowment policy itself and would not usually form part of the investment arrangement.
Mortgage interest tax relief linked to endowment mortgages was gradually phased out in the UK and is no longer generally available for most residential borrowers.
Tax treatment can vary depending on the type of policy and your individual circumstances, so professional tax advice may be appropriate if you’re unsure.
It depends on the performance of the underlying investment within the policy. Some endowment policies generated enough growth to fully repay the mortgage and even some extra on top, while others fell short.
Most providers now issue projection statements indicating whether the policy is likely to meet its target or not.
This was a type of guarantee offered by some insurers to help reduce potential shortfalls for qualifying policyholders whose endowment investments underperformed. The terms and eligibility criteria varied depending on the provider and specific policy type.
It was a product designed to start with lower monthly payments in the early years of the mortgage term, then increase later on.
These products were intended to make mortgage costs more manageable initially. However, repayments would usually increase later in the term, which could make the mortgage more expensive over time.
Yes, in most cases, borrowers can make overpayments on the mortgage itself, depending on the lender’s terms and any early repayment restrictions. Making overpayments can help reduce the outstanding balance and potentially lower the impact of any future endowment shortfall.
