A Self-Invested Personal Pension (SIPP) and a standard personal pension are both types of defined contribution pension. You pay in, your employer may pay in, the government adds tax relief, and the money is invested to grow over time. When you reach age 55 (rising to 57 from April 2028), you can access the pot. The fundamental difference between them is the range of investments available and the level of control you have.
Key Differences at a Glance
SIPP vs Personal Pension Comparison
| Feature | SIPP | Personal Pension |
|---|---|---|
| Investment choice | Wide — shares, ETFs, investment trusts, bonds, commercial property | Limited — selected funds from the provider |
| Charges | Platform fee + fund charges + dealing fees | Often a simpler single charge (AMC) |
| Control | You choose investments (or your adviser does) | Provider's fund range only |
| Complexity | Higher — requires investment knowledge | Lower — choose a fund and contribute |
| Minimum investment | Varies (some from £1) | Varies |
| Drawdown | Usually built in | May need to transfer for drawdown |
| Suitable for | Active investors, those with advisers | Those wanting simplicity |
When a SIPP Makes Sense
- You want control over investments: If you want to choose individual shares, ETFs, investment trusts, or specific bond funds, a SIPP gives you that flexibility.
- You work with a financial adviser: Many advisers use SIPPs as the vehicle for managing their clients' pension investments, as SIPPs support the widest range of investment options.
- You have a larger pension pot: The percentage-based platform fees on SIPPs become more cost-effective at larger pot sizes, particularly with providers that cap their platform fee.
- You want specific assets: Commercial property, for example, can only be held in a SIPP (not a standard personal pension). Some SIPPs also allow unquoted shares and certain alternative investments.
- You want drawdown built in: Most SIPPs offer flexible drawdown as standard, allowing you to take income in retirement without transferring to a different product.
When a Personal Pension Makes Sense
- You want simplicity: If you prefer to pick a fund (or accept the default) and make regular contributions without managing investments, a personal pension is straightforward.
- You are just starting out: For smaller pension pots, the simpler charging structure of a personal pension can be more cost-effective than a SIPP.
- Your workplace pension is a personal pension: Auto-enrolment pensions are often personal pensions (such as those from Nest, Scottish Widows, Aviva, or Legal & General). There is nothing wrong with staying in these — the default funds are typically well-diversified and low-cost.
- You do not want to make investment decisions: A personal pension with a well-chosen default fund (such as a target-date or lifestyle fund) can be a perfectly good long-term solution.
Charges Comparison
Typical Charges
- SIPP Platform Fee
- 0.15%–0.45% per year
- Plus fund charges (0.05%–0.80%) and dealing fees (£0–£12 per trade)
- Personal Pension (all-in)
- 0.50%–1.00% per year
- Typically a single annual management charge covering platform and fund
Charges vary widely between providers. A SIPP invested in low-cost index funds can have a total cost below 0.30%, while a personal pension with actively managed funds might cost 0.75%–1.00%. Over a 30-year saving period, even a 0.5% difference in annual charges can reduce your final pot by 10–15%.
Tax Treatment Is Identical
There is no difference in tax treatment between a SIPP and a personal pension. Both receive tax relief on contributions in the same way:
- Tax relief: Basic rate (20%) is added automatically; higher (40%) and additional (45%) rate relief is claimed via Self Assessment.
- Annual allowance: The same £60,000 annual allowance applies to both.
- Pension Commencement Lump Sum (PCLS): You can take 25% of your pot tax-free from either type (up to £268,275).
- Tax-free growth: Investments in both SIPPs and personal pensions grow free from income tax and capital gains tax.
Transferring Between Them
You can transfer from a personal pension to a SIPP, or vice versa, at any time. Transfers are common — for example, you might consolidate old workplace personal pensions into a SIPP for more investment control, or transfer a SIPP into a simpler personal pension as you approach retirement. Transfer times vary (typically 4–8 weeks) and some providers charge exit fees, so check before transferring. In-specie transfers (transferring investments without selling them) are possible between some providers, avoiding the need to sell and rebuy.
