TL;DR

An annuity converts pension savings into a guaranteed lifetime income but the decision is irreversible once the policy starts. Rates vary significantly between providers and depend on health — smokers and those with serious health conditions may qualify for enhanced annuity rates up to 30% higher than standard.

What an annuity is

An annuity is an insurance product that converts a pension lump sum into a guaranteed income for life or a fixed period. Once purchased, the terms are fixed and irreversible — the capital is exchanged for the income guarantee. The annuity rate determines the annual income paid; rates depend on the annuity provider, the policyholder's age, health, the options selected and prevailing gilt yields.

The risks most people do not check

Taking the pension provider's default annuity rate is almost always suboptimal. The open market option allows you to shop around for the best annuity rate rather than accepting what your pension provider offers. Rates vary significantly between providers — the difference between the best and worst rates can be 20 percent or more, representing thousands of pounds over a lifetime.

Health conditions can significantly increase the rate. Enhanced annuities, also called impaired life annuities, pay higher rates to people with health conditions that may reduce life expectancy. Conditions including diabetes, heart disease, high blood pressure, obesity and smoking history can qualify for rates 10 to 30 percent above standard. Always declare health information when obtaining annuity quotes.

The decision is irreversible. Once an annuity starts, the capital is exchanged for the income stream. If you die shortly after purchase, the remaining capital may be lost to the insurance company depending on the guarantee period selected. A five-year or ten-year guarantee period ensures payments continue to beneficiaries for the guaranteed period even if death occurs earlier.

Inflation erodes level annuity income over time. A level annuity pays the same nominal amount throughout retirement. Over 20 years at three percent inflation, the real value of a level income falls by approximately 45 percent. Inflation-linked annuities start at a lower income but maintain real value.

What to verify before purchasing

Obtain quotes from at least five providers using an independent annuity broker or comparison service. Disclose all health conditions accurately. Model level versus inflation-linked income over your expected retirement duration. Consider joint life options if you have a partner who would continue to need income. Understand the guarantee period options and their cost.

Where to complain

Unsuitable annuity advice or misrepresentation of terms goes to the Financial Ombudsman Service after the provider's internal complaints process.

Frequently asked questions

Can I change my mind after buying an annuity?

There is typically a 30-day cooling-off period after an annuity is issued during which you can cancel. After this period, the decision is irreversible. Ensure you are fully committed before the cooling-off period expires.

What is an enhanced annuity?

An enhanced or impaired life annuity pays a higher income rate to people with health conditions or lifestyle factors that may reduce life expectancy. Always obtain an enhanced rate quote by disclosing all relevant health information, even if you consider your condition minor or well-controlled.

What happens to my annuity when I die?

This depends on the options chosen at purchase. A single life annuity with no guarantee period ceases at death. A joint life annuity continues payments to a spouse or civil partner at a reduced rate. A guaranteed period ensures payments continue for the period even if death occurs earlier.

What is the open market option?

The open market option is your right to shop around for the best annuity rate rather than accepting your pension provider's default offer. Exercising the open market option is strongly advisable as rates vary significantly between providers.

How are annuity rates set?

Annuity rates are primarily determined by gilt yields (UK government bond returns), which represent the return the insurer can earn on the capital invested. They also reflect the insurer's mortality assumptions for the annuitant's age and health profile. When gilt yields are high, annuity rates are more favourable.
