Investing looks harder than it is. Most UK long-term wealth is built with three ingredients: a tax wrapper (ISA or SIPP), a low-cost global index fund or ETF, and a monthly standing order. Everything on this hub is designed to help you understand those three ingredients well enough to run them yourself, or to recognise when active choices are worth the extra cost.

For DIY ETF portfolios, InvestEngine at 0% platform fee. For Vanguard-only holdings, Vanguard Investor UK at 0.15%. For larger pots (£100k+), Interactive Investor's flat fee often wins. See Best investment platforms UK.
Workplace pension employer match first (free money). Then it depends on tax band and time horizon. Higher-rate taxpayers get more benefit from SIPP; those needing pre-55 access lean ISA. See ISA vs Pension.
Under 0.5% all-in is achievable for a passive DIY UK investor. Under 0.3% is possible on InvestEngine + broad-market ETFs. Anything over 1% deserves scrutiny. See Investment fees explained.
