Interest rates are one of the most important things to understand when considering a lifetime mortgage — not because they work in a complicated way, but because the effect of roll-up interest over a long period can be significant, and knowing what to expect from the outset helps you make a more informed decision.
How lifetime mortgage interest rates work
Lifetime mortgage interest rates are fixed for life at the point you take out the plan. Unlike a standard mortgage where rates are typically fixed for 2, 3 or 5 years before reverting to a variable rate, a lifetime mortgage locks in a single rate that applies for the entire duration — however long that turns out to be.
This is actually one of the more overlooked advantages of a lifetime mortgage: you know exactly what rate you're paying from day one, and that rate will never change regardless of what happens to interest rates in the wider market. There's no risk of your costs increasing because the Bank of England raises rates.
What are typical lifetime mortgage rates?
Rates vary by lender, your age, the loan-to-value ratio, and the features you choose (such as drawdown, inheritance protection, or voluntary repayment options). As a general guide, rates in the current market tend to fall broadly in the following ranges:
| Product type | Approximate rate range | Notes |
|---|---|---|
| Standard lump sum | 5.5% – 7.5% AER | Lower LTV and older applicants may access the lower end |
| Drawdown lifetime mortgage | 5.5% – 7.5% AER | Interest only charged on funds drawn, not the reserved facility |
| With inheritance protection | Slightly higher | You ring-fence a percentage of your property's value for your estate |
| Enhanced / impaired health | Often lower | Health conditions can qualify you for a better rate or higher release |
These are indicative figures only — the rate on any specific plan depends on your individual circumstances and the lender. A whole-of-market adviser will compare rates across all providers to find the most suitable option for you.
How roll-up interest works — and why it matters
With a standard lifetime mortgage, you make no monthly repayments. Instead, interest is added to your loan balance each month and compounds over time. This is called roll-up interest, and it's the aspect of lifetime mortgages that people most commonly underestimate.
Because the interest compounds, the total amount owed grows at an accelerating rate over time. The longer the loan runs, the more significant the effect.
Initial loan: £100,000
Interest rate: 6.0% AER (fixed for life)
After 10 years: approximately £179,000
After 15 years: approximately £240,000
After 20 years: approximately £321,000
These figures assume no repayments are made. If the property value grows over the same period, the equity remaining in the property may still be significant — but it's important to understand the trajectory before committing.
The no-negative-equity guarantee means you (or your estate) can never owe more than the sale proceeds of your property — even if the rolled-up loan exceeds its value. This is a requirement of all Equity Release Council member products.
Can you reduce or stop the roll-up?
Yes — most modern lifetime mortgage products allow you to make voluntary repayments, either partial or full interest payments, without penalty. This is one of the most important features to look for when comparing products, and one that can make a significant difference to the overall cost.
- Paying all the monthly interest stops the roll-up completely — your balance stays flat and your estate is fully protected from compounding.
- Paying partial interest slows the roll-up proportionally.
- Making no payments allows the balance to compound as in the example above.
Crucially, with most products these payments are voluntary — meaning if your circumstances change and you can no longer afford to make them, you can stop without penalty and revert to the standard roll-up structure. This flexibility makes the voluntary repayment feature worth understanding carefully.
How rates compare to standard mortgages
Lifetime mortgage rates are generally higher than standard residential mortgage rates. This reflects the nature of the product — the lender has no certainty of when the loan will be repaid, receives no monthly payments to offset the interest, and carries the risk of the no-negative-equity guarantee.
However, the comparison isn't straightforward. A standard mortgage requires you to make monthly payments, which has its own cash flow implications. A lifetime mortgage with no payments frees up that cash but at the cost of a higher rate and compounding balance. For many people the relevant comparison isn't "which has a lower rate" but "which structure suits my situation and priorities."
Does your health affect your rate?
Yes — many lifetime mortgage lenders offer enhanced terms for applicants with certain health conditions or lifestyle factors. This is called an enhanced or impaired-life lifetime mortgage. If you have conditions such as heart disease, diabetes, certain cancers, or a history of smoking, you may qualify for a higher release amount, a lower rate, or both.
It's worth completing a full health questionnaire as part of the advice process rather than assuming standard terms will apply.

Yes. Most modern lifetime mortgage products allow voluntary interest payments — partial or full — without penalty. Paying all the monthly interest stops the roll-up entirely. These payments are typically voluntary, meaning you can stop if circumstances change.
Generally yes, reflecting the nature of the product. However, the comparison isn't straightforward — the relevant question is usually which structure suits your situation, not which has a lower headline rate.
