Annuity Types Explained: A 2026 UK Retirement Guide

Quick answer

An annuity is an insurance product that turns your pension savings into a guaranteed income. The main types are the lifetime annuity (paying for the rest of your life) and the fixed-term annuity (paying for a set number of years). Within those, you choose level or rising income, single or joint life, guarantee periods, and enhanced rates for health conditions. The income is taxed as earned income.

What an annuity actually is

When you reach retirement with a defined contribution pension, you have to decide how to turn that pot into an income. One option is to buy an annuity. You hand a lump sum to an insurer and, in return, they promise to pay you a set income on a fixed schedule. The key appeal is certainty: the payments do not depend on how stock markets behave, so you know exactly what lands in your account.

That certainty comes at a price. With most lifetime annuities you give up access to the underlying capital, and once the contract starts you generally cannot change your mind. So choosing the right shape of annuity matters enormously, because you are locking in a decision that may run for 20 or 30 years.

Before buying, you can normally take up to 25% of the pot as a tax-free lump sum (subject to the lump sum allowance), then use the remainder to buy income. Work through the trade-off with our

The two core structures

Lifetime annuity

A lifetime annuity pays income for as long as you live, however long that turns out to be. This is the classic product people picture when they hear the word annuity. The headline benefit is that you cannot outlive the income, which removes longevity risk entirely. The downside is that if you die early, you may receive far less than you paid in unless you added protection features.

Fixed-term annuity

A fixed-term annuity pays a guaranteed income for a chosen period -- often five or ten years -- and then returns a maturity value. That maturity sum can be used to buy another annuity, moved into drawdown, or used in some other way. Fixed-term annuities suit people who want guaranteed income now but prefer to keep their options open, perhaps because they expect annuity rates or their own health to change.

The income-shape options

Within a lifetime annuity, several choices shape how much you receive and what happens over time.

Level vs escalating

A level annuity starts higher, but inflation steadily eats into its real value. Over a long retirement, prices can rise considerably, so the same payment buys less each year. An escalating annuity starts lower but increases annually, protecting your spending power. The catch is that it can take many years for the total received from an escalating annuity to overtake a level one, so your health and life expectancy weigh heavily on the decision.

Single vs joint life

A single-life annuity pays only you and usually stops when you die. A joint-life annuity continues paying a percentage -- commonly 50% or 100% -- to your spouse or partner after your death. Couples who rely on the income to cover shared bills often choose joint life despite the lower starting figure, because it protects the survivor.

Guarantee periods and value protection

A guarantee period ensures the annuity keeps paying for a set number of years even if you die soon after buying it, so the money is not simply lost. Value protection works differently, returning a portion of the original purchase price to your estate on death. Both reduce your starting income but soften the risk of dying early.

Enhanced and impaired-life annuities

If your health or lifestyle is likely to shorten your life expectancy, you may qualify for an enhanced annuity. Because the provider expects to make payments for fewer years, it offers a higher income for the same pot. Qualifying factors can include smoking, diabetes, high blood pressure, heart conditions and many others.

This is one of the most overlooked sources of extra retirement income. Many people accept a standard quote without disclosing health details and end up with less than they were entitled to. Always answer health and lifestyle questions fully and honestly when getting quotes -- the uplift can be significant.

Investment-linked annuities

An investment-linked annuity ties part of your income to the performance of underlying funds. Income can rise if investments do well but can also fall, sometimes subject to a guaranteed minimum. These products sit between a conventional annuity and drawdown: you keep some growth potential while retaining a degree of guaranteed income. They are more complex and carry investment risk, so they suit confident investors rather than those who want pure certainty.

Annuity vs drawdown

The main alternative to an annuity is income drawdown, where your pot stays invested and you take flexible withdrawals.

Neither is universally better. A common approach is to use an annuity to cover essential, non-negotiable bills -- so the basics are always met -- and keep the rest in drawdown for flexibility and potential growth. That blend gives a secure floor with upside. The new full State Pension of GBP 241.30 per week (around GBP 12,548 a year) already provides a guaranteed base, which influences how much extra guaranteed income you actually need from an annuity.

How annuity income is taxed

Income from an annuity bought with pension savings is treated as earned income and taxed through PAYE. It uses your Personal Allowance of GBP 12,570, then is taxed at the basic rate of 20% on income between GBP 12,571 and GBP 50,270, the higher rate of 40% up to GBP 125,140, and the additional rate of 45% above that. Scottish taxpayers pay Scottish rates instead, which run from a 19% starter rate up to a 48% top rate.

Because the annuity income stacks on top of your State Pension and any other income, it is easy to drift into a higher band than expected. A purchased life annuity bought with non-pension money is taxed differently, with part of each payment treated as a return of capital and only the rest as taxable income.

How to compare quotes

You are not tied to your existing pension provider. The open market option lets you buy an annuity from any insurer, and rates differ widely. Shopping around -- and disclosing every relevant health and lifestyle detail -- can add a meaningful amount to your lifetime income.

When comparing, make sure each quote uses the same options: the same escalation, the same single or joint life basis, and the same guarantee period. Comparing a level single-life quote against a joint-life escalating quote tells you nothing useful, because they are fundamentally different products.

Key questions to settle before you buy:

• How much guaranteed income do I actually need once the State Pension is counted?
• Do I want level income now or protection against inflation later?
• Does my partner need an income if I die first?
• Could a health condition qualify me for an enhanced rate?
• Would a fixed-term annuity keep my options open?

The bottom line

An annuity is the simplest way to turn a pension pot into a guaranteed income you cannot outlive, and the type you choose -- lifetime or fixed-term, level or escalating, single or joint life -- shapes both how much you receive and how protected your family is. Disclose your health, use the open market option, and weigh the certainty of an annuity against the flexibility of drawdown. For most people the right answer is a thoughtful blend rather than all of one or the other.
