How to choose
Percentage vs flat-fee platforms
Percentage platforms (0.25–0.45%) win for small pots. Flat-fee platforms (£10–£15/month) win once you cross ~£50,000. Switch as your pot grows.
Active vs passive
Low-cost global index funds (0.1–0.25% OCF) beat 80%+ of active funds over 10+ years. Start there unless you have a genuine edge.
Use your full allowance early
£20,000 invested on 6 April vs 5 April next year is one extra year of compounding — about 7% more on average.
Don't panic-sell
Time in the market beats timing the market. Set up a monthly direct debit and ignore the news.
