UK Retirement
Planning Hub

The PLSA Retirement Living Standards, the most widely cited UK benchmark, suggest a single retiree needs around £14,400/year for a minimum lifestyle, £31,300/year for moderate, and £43,100/year for comfortable (2024 figures). Using the 4% rule, that implies retirement pots of roughly £360,000, £780,000 and £1.08m respectively, on top of a full state pension. The exact number depends on your target lifestyle, where you live, whether you own your home outright, and your other income sources.

For most UK workers, the order is: workplace pension up to the employer match first (free money), then LISA if eligible (25% government bonus on £4,000/year), then Stocks & Shares ISA, then additional pension contributions. Pensions get tax relief at your marginal rate but are locked until 55 (rising to 57 in 2028). ISAs have no tax relief but are fully flexible and tax-free on withdrawal. Splitting between both usually produces the best combination of tax efficiency and access.

FIRE, Financial Independence, Retire Early, is a framework for quitting work decades before traditional retirement age. The core calculation is your annual spending multiplied by 25 (based on the 4% safe withdrawal rate). If you spend £30,000/year, your FIRE number is £750,000. UK FIRE has specific nuances: the state pension kicks in at 67, you can access pensions from 55/57, and ISAs are your main pre-pension-age vehicle. A blended approach, ISAs for early years, pensions for later, is the standard UK FIRE strategy.

Yes, but the rules are changing. Currently you can access a personal or workplace pension from age 55, with 25% tax-free and the rest taxable as income. From 6 April 2028 that minimum age rises to 57. ISAs have no age restriction, so if you are targeting retirement before 55/57, you will need to bridge the gap with ISA savings. Our FIRE Calculator and Retirement Compound Calculator both let you model an early retirement date.

The 4% rule says you can withdraw 4% of your portfolio in year one of retirement, increase that withdrawal with inflation each year, and have a very high probability of not running out over 30 years. It comes from US data (the Trinity Study) and is based on a mixed stock/bond portfolio. UK-specific studies suggest a slightly more conservative 3.5% sustainable withdrawal rate for UK investors, particularly because UK equity returns have historically been lower than the US. Either way, the rule is a starting point, not a guarantee, sequence-of-returns risk in the first 5-10 years matters more than the average return.
