An index linked annuity can potentially offer you a secure income in retirement, and one that protects you against rising prices and inflation over time. Here, we’ll explain what an index-linked annuity is, how it works, how it compares with fixed annuities, the pros and cons, and where to find the best index linked annuity rates in the UK.
What is an index linked annuity?
An index linked annuity is a type of pension product that provides you with income in retirement that rises over time, usually in line with inflation. So, for people worried about the cost of living increasing after you’ve stopped working, this type of annuity can provide valuable long-term protection.
Because an index-linked annuity is designed to maintain your purchasing power, it can be particularly valuable if you expect to live many years in retirement. However, it also comes with trade-offs that you need to understand before making a decision.
Index-linked annuities are also sometimes referred to as increasing annuities or inflation-linked annuities.
How do they work?
Unlike a fixed annuity, where your income remains at the same level, index-linked annuities provide you with payments that increase each year based on an inflation measure, typically the Retail Prices Index (RPI), or a fixed escalation rate.
Here’s how an index-linked annuity usually works:
-
You exchange part or all of your pension pot for a guaranteed income
-
Your income increases each year by a specific measure or rate
-
Payments continue for life (or for joint lives if selected)
The amount you receive with an index or inflation-linked annuity depends on factors such as:
-
Your age and health
-
Interest rates at the time of purchase
-
Whether income increases are linked to inflation or another figure
-
Whether you choose a single or joint life annuity
-
Optional features like guarantee periods or value protection
Fixed versus index linked annuities
The biggest decision when buying an annuity is often whether to choose a fixed (level) income or one that increases over time (index-linked, for example). Here’s how they compare:

Which type should you choose?
On paper, an index-linked annuity might seem like a no-brainer, but because payments are expected to rise over time, the initial income is usually significantly lower. So, you need to last long enough in retirement to see the added value.
Firstly, there’s the breakeven point at which your annuity payments cross your original lump sum. And then, over future years, the increasing payments may catch up and eventually exceed the fixed option.
Compared to a fixed annuity, index or inflation-linked annuities are particularly suited to people who:
-
Expect a long retirement
-
Have another source of income
-
Are in good health, potentially living for many years
-
Want a predictable rising income
-
Have concerns about the risk of inflation
How to get the best index-linked annuity
Finding the best index-linked annuity rate usually involves more than simply accepting your pension provider’s offer. Here are some key steps to find the most competitive annuity:
-
Get professional advice: It’s well worth having a chat with an expert because annuities are usually irreversible once purchased. Independent advice can help ensure the structure matches your retirement goals and offer you access to the best annuity rates.
-
Look at the whole market: A major benefit of getting independent advice is that your adviser can compare annuity rates and products from all providers, not just where your current pension is held. Shopping around can significantly increase your annuity income.
-
Check enhanced annuity eligibility: Health conditions, lifestyle factors, or medications may mean you qualify for a higher income and better index-linked annuity rates. If you have a partner, you might also want to consider a joint life index-linked annuity.
-
Compare escalation types: Some UK RPI-linked annuity rates increase with RPI, while others use fixed percentages, such as 3% or 5%. The best overall choice depends on your inflation expectations, priorities, and circumstances.

FAQs
A calculator can provide rough estimates of potential income and show how payments might grow over time. However, calculators cannot account for personal health factors, current provider rate differences, or detailed retirement planning, so you should only use an index-linked annuity calculator as a starting point.
