An ISA and a SIPP are different tax wrappers that do different jobs, so it isn’t necessarily an either/or choice — many people hold both.
- Individual Savings Account (ISA): accessible at any time, with no tax on gains and income within the account
- Self-Invested Personal Pension (SIPP): designed for retirement, includes tax relief on contributions, and is generally not accessible until the normal minimum pension age
InvestEngine offers a SIPP with no account fees on its DIY service (you pay only the underlying ETF costs), alongside its ISA, so you can hold both in one place. Whether a SIPP is right for you depends on your goals and circumstances.
