Endowment Mortgage vs Repayment Mortgage UK 2026: What Homeowners Should Know
An endowment mortgage pairs interest-only borrowing with a separate investment policy meant to repay the capital, but many older policies fell short of their target. A repayment mortgage guarantees the capital is cleared through regular monthly payments. Here is what borrowers with either arrangement should know for 2026.
TL;DR - 30-Second Summary
- - Endowment mortgage: interest-only payments plus a separate investment policy, which for many older policies fell short of clearing the mortgage
- - Repayment mortgage: higher monthly payments, but capital is guaranteed to be cleared by the end of the term
- - If you still have an endowment: check your latest projection and consider switching some or all to repayment
Side by Side: Endowment vs Repayment Mortgage
| Feature | Endowment Mortgage | Repayment Mortgage |
|---|---|---|
| Monthly mortgage payment | Interest only (lower) | Capital plus interest (higher) |
| How capital is repaid | Separate endowment policy — not guaranteed | Built into the mortgage payment — guaranteed if kept up |
| Shortfall risk | Yes — many older policies underperformed | None |
| Life insurance included | Often bundled into the endowment | Usually arranged separately |
| Available to new borrowers today | Very rarely | Standard, widely available |
What Is an Endowment Mortgage?
An endowment mortgage is structured on an interest-only basis, meaning your monthly mortgage payment covers only the interest charged on the loan, with the original capital remaining outstanding throughout the term. Separately, the borrower pays premiums into an endowment life insurance policy, designed to grow through investment returns and mature at the end of the mortgage term with enough value to repay the outstanding capital in full. These were common in the 1980s and 1990s but proved controversial when many policies underperformed their original growth projections.
What Is a Repayment Mortgage?
A repayment mortgage (capital and interest mortgage) is today's standard structure, where each monthly payment is calculated to cover the interest due plus a portion of the capital, gradually reducing the balance over the term until it reaches zero. This gives certainty that the mortgage will be paid off by the end of the term, provided payments are kept up, without needing to rely on the performance of a separate investment.
What Should You Do?
If you still have an endowment mortgage...
- - Request a current projection from your endowment provider
- - Consider switching some or all of the balance to repayment
- - Plan for a shortfall if the projection shows one
- - Review any life insurance gap if you surrender the endowment
If you are taking out a new mortgage...
- - A repayment mortgage is the standard, safest choice
- - Arrange separate term life insurance if you have dependants
- - Consider interest-only with an approved repayment vehicle only with strong financial planning
- - Compare rates using a repayment mortgage calculator
Frequently Asked Questions
What is an endowment mortgage?
An endowment mortgage is a mortgage structured on an interest-only basis, where the borrower pays only interest to the lender each month while separately paying into an endowment life insurance policy intended to grow enough by the end of the term to repay the original capital in one lump sum. These were widely sold from the 1980s through the 1990s but are rarely arranged for new borrowers today.
What is a repayment mortgage?
A repayment mortgage is the standard modern mortgage structure, where each monthly payment covers both interest and a portion of the capital borrowed, so the balance steadily reduces to zero by the end of the agreed term, guaranteeing the mortgage is paid off (assuming payments are kept up) without relying on a separate investment.
Why did many endowment mortgages fall short of repaying the loan?
Endowment policies were often sold with optimistic projected growth rates that assumed strong long-term stock market and with-profits fund performance. When actual returns fell short — particularly after the market downturns of the early 2000s — many policies failed to grow enough to clear the mortgage balance, leaving borrowers with a shortfall to make up from other savings.

What should I do if I still have an endowment mortgage today?
Contact your endowment provider for a current projection showing whether your policy is on track, ahead, or behind to repay your mortgage balance at maturity. If there is a projected shortfall, options include increasing monthly savings elsewhere, switching part of the mortgage to a repayment basis, overpaying the endowment premium, or extending the mortgage term, depending on your lender's flexibility and your circumstances.
Can I switch from an endowment mortgage to a repayment mortgage?
Yes, most lenders allow borrowers to convert some or all of an interest-only endowment mortgage balance to a repayment basis, which then guarantees the capital is paid off through your regular mortgage payments rather than depending on the endowment policy's performance. You typically keep the endowment policy running separately as a savings or life insurance product, or surrender it, depending on its remaining value and any penalties for doing so.
Does a repayment mortgage cost more each month than interest-only?
Yes, monthly payments on a repayment mortgage are higher than the interest-only element of an equivalent endowment mortgage, because you are also repaying capital each month rather than saving separately for it. Over the full term, however, a repayment mortgage removes the risk of a shortfall and guarantees the debt is cleared, provided payments are maintained.
Is life insurance still needed with a repayment mortgage?
Yes, a repayment mortgage does not include life insurance automatically — many borrowers arrange separate decreasing term life insurance (aligned to the falling mortgage balance) or level term life insurance to protect dependants if they died before the mortgage was paid off, whereas an endowment mortgage typically included a life insurance element as part of the endowment policy itself.
Are endowment mortgages still available to new borrowers in 2026?
Very rarely. Mainstream lenders overwhelmingly offer repayment mortgages, or interest-only mortgages with an approved separate repayment vehicle such as an ISA or pension, rather than the traditional endowment-linked structure, reflecting the shortfall problems experienced with older endowment policies and tighter mortgage regulation since the 2014 Mortgage Market Review.
