Can You Switch Water Supplier? Why the Answer's No

Geopolitical Risk: The One Threat to Your Portfolio You Can't Hedge

In 1979 the Warsaw Pact planned to nuke West Germany, Belgium and Denmark, but not Britain or France. The lesson for your portfolio: the risk you can't hedge is the one that should never make you sell.

What Is Financial Nihilism?

Young people aren't reckless for betting on crypto instead of saving. A Chicago paper shows it turns rational once a house is out of reach. The catch is it locks in the loss.

Frequently asked questions

What is FIRE in the UK?
FIRE stands for Financial Independence, Retire Early. The idea is to save aggressively, invest in low-cost index funds inside tax-efficient wrappers like ISAs and SIPPs, and build a portfolio large enough that the safe withdrawal rate covers your annual expenses. Read our brutal-reality intro to UK FIRE for the full playbook.
How does a UK Stocks & Shares ISA work?
A Stocks & Shares ISA is a tax-free wrapper. You can pay in up to £20,000 per tax year (the total ISA allowance, shared with Cash ISAs and LISAs) and any capital gains, dividends, and interest earned inside the wrapper are completely free of UK tax. There is no need to declare anything on a self-assessment. See our platform comparison.
How much do I need to retire in the UK?
A common rule of thumb is 25× your annual spending (the "4% rule"). On a £30,000-a-year retirement that means a portfolio of £750,000 outside the State Pension. Our FI Number Calculator works this out for your numbers and projects how long it will take at your savings rate.
What is the difference between an ISA and a pension?
An ISA gives you tax-free growth and tax-free withdrawals at any age, with no upfront tax relief. A pension gives you tax relief on the way in (a 20% basic-rate top-up or higher) but locks the money away until age 57 (rising to 58 by 2028) and taxes withdrawals above the 25% tax-free lump sum at your income tax rate. Most UK savers use both.
Is Freedom Isn't Free really free?
Yes. Every article, calculator, and comparison on the site is free to use without an account, and we don't sell user data. Some links to platforms or books are affiliate links, which means we earn a small commission if you sign up, and we sometimes run clearly-labelled sponsored placements. We always disclose these. The site is also supported by readers via Buy Me a Coffee.
