What is a SIPP and is it right for me?
A Self-Invested Personal Pension gives you full control over your pension investments. That control is an advantage — but only if you want it.
- ▸A SIPP (Self-Invested Personal Pension) is a pension wrapper that lets you choose your own investments — funds, shares, ETFs, investment trusts, and sometimes commercial property.
- ▸SIPPs get the same tax relief as any other pension: basic-rate relief added automatically, higher/additional rate claimed via self-assessment.
- ▸They suit people who want investment choice, are consolidating old pensions, or want lower fees than their workplace scheme. They don't suit people who prefer not to make investment decisions.
- ▸Total costs on a low-cost SIPP with a passive fund can be as low as 0.2–0.4% per year — often cheaper than workplace defaults with active management.
SIPP definition and how it works
A SIPP is a type of personal pension. Like all registered pension schemes, it benefits from tax relief on contributions, tax-free growth within the wrapper, and the option to take 25% as a tax-free lump sum from age 55 (rising to 57 in 2028).
The "self-invested" part means the account holder selects the investments, rather than having a fund manager or employer make the choice. Most SIPP providers offer access to thousands of funds, individual shares, ETFs, investment trusts, and government bonds. Some "full" SIPPs also allow commercial property and unquoted shares, though these are specialist products with higher fees and additional complexity.
The contribution and withdrawal rules are identical to any other defined contribution pension:
- Annual allowance of £60,000 (2025/26), reduced for very high earners
- Tax relief at the individual's marginal rate
- No access before minimum pension age (55, rising to 57 in 2028)
- 25% tax-free lump sum, with the rest taxed as income via drawdown or annuity
The SIPP is a wrapper, not an investment. What matters for returns is what goes inside it.
Who a SIPP suits (and who it doesn't)
A SIPP is a good fit for someone who:
- Wants to choose their own investments rather than accepting a default fund
- Is consolidating multiple old workplace pensions into one account
- Wants access to low-cost index funds that their workplace scheme does not offer
- Is self-employed and has no workplace pension
- Has maximised employer contributions and wants to top up in a separate wrapper
A SIPP is a poor fit for someone who:
- Has no interest in choosing investments (a workplace default fund does this automatically)
- Has an employer match they haven't yet maximised (employer contributions go into the workplace pension, not a SIPP)
- Has a small pot where the SIPP's fees — even at low-cost providers — would be proportionally high
The critical point: a SIPP does not replace a workplace pension if the employer is still contributing. It supplements it. Always capture the full employer match first, then consider whether additional contributions go into the workplace scheme or a SIPP.
SIPP vs workplace pension: the key differences
| Feature | SIPP | Workplace pension |
|---|---|---|
| Investment choice | Full range — funds, shares, ETFs | Limited menu chosen by employer/provider |
| Employer contributions | Not directly (employer must set up payroll) | Yes — auto-enrolment minimum 3% |
| Tax relief method | Relief at source or net pay (varies) | Typically net pay (salary sacrifice) or relief at source |
| Typical total cost | 0.15–0.45% (low-cost provider + passive fund) | 0.3–0.75% (varies widely) |
| Flexibility at retirement | Full drawdown options | Some schemes restrict drawdown |
The main guide on SIPPs at /guides/sipps covers provider comparisons and fee structures in more detail.
Choosing a SIPP provider
Several factors differentiate providers:
Fee structure: Some charge a percentage of the pot (e.g. 0.15–0.45%), others charge a flat annual fee (e.g. £50–£120/year). Percentage fees suit smaller pots. Flat fees suit larger pots (roughly above £40,000–£80,000 depending on the provider). The pension fee calculator models the crossover point.
Fund range: Most mainstream SIPPs offer several thousand funds. The key question is whether they offer the specific low-cost index funds you want — typically global equity trackers with OCFs under 0.25%.
Drawdown capability: Not all SIPPs offer flexible drawdown at retirement. If the SIPP is intended to be the account from which income is eventually drawn, check that drawdown is available without transferring to another provider.
FSCS protection: SIPP providers are covered by the Financial Services Compensation Scheme up to £85,000 for investment claims. The investments within the SIPP (funds, shares) are held separately from the provider's own assets, so provider insolvency does not typically affect the holdings.
The Pension Bible provider directory lists SIPP providers with fee comparisons, though the directory is informational and does not constitute a recommendation.
- ▸A SIPP is a registered pension scheme regulated by the FCA. Contributions qualify for tax relief on the same basis as any other UK pension. [FCA]
- ▸The FSCS protects SIPP investments up to £85,000 per provider in the event of provider failure, though investments held in nominee accounts are typically ring-fenced from creditors. [FSCS]
- ▸Auto-enrolment requires a minimum employer contribution of 3% of qualifying earnings. This contribution goes into the workplace pension, not a SIPP. [The Pensions Regulator]
