SIPP Guide: Self-Invested Personal Pensions Explained

investments2026-03-058 min readBy CalculatorZone

What Is a SIPP?

A Self-Invested Personal Pension (SIPP) is a pension wrapper that gives you full control over your investment choices. Unlike workplace pensions that typically offer a limited selection of funds, a SIPP lets you invest in individual stocks, bonds, funds, ETFs, investment trusts, and commercial property.

Tax Benefits

SIPPs receive the same generous tax relief as other pensions:

  • Basic rate (20%): Contribute £80, the government adds £20
  • Higher rate (40%): Claim an extra £20 back via Self Assessment
  • Additional rate (45%): Claim an extra £25 back

Your investments grow free of income tax and capital gains tax inside the SIPP. The annual allowance is £60,000.

Who Should Use a SIPP?

SIPPs are ideal for: self-employed people without a workplace pension, experienced investors wanting more control, higher earners maximising tax relief, and anyone consolidating multiple old pensions.

Costs

SIPP platform fees range from 0.15-0.45% per year. Popular platforms include AJ Bell (0.25%), Hargreaves Lansdown (0.45%), and Interactive Investor (flat fee £11.99/month). For larger pots, flat-fee platforms become better value.

Accessing Your SIPP

From age 55 (rising to 57 in 2028): take 25% as a tax-free lump sum, then drawdown, annuity, or a combination. You can also take smaller lump sums, each 25% tax-free.

Risks

With greater control comes greater responsibility. Poor investment choices can reduce your retirement income. If you are not confident investing, consider a ready-made portfolio or seek financial advice.

Frequently Asked Questions

What is the difference between a SIPP and a workplace pension?

A SIPP gives you full control over investment choices (stocks, funds, ETFs), while workplace pensions offer a limited fund selection. SIPPs also lack employer contributions unless you arrange them.

Can I transfer my workplace pension to a SIPP?

Usually yes. You can transfer most defined contribution pensions to a SIPP. Check for exit fees and whether you'd lose any valuable benefits (like guaranteed annuity rates) before transferring.
