A Self-Invested Personal Pension (SIPP) is one of the most powerful savings vehicles available in the UK. Unlike a workplace pension, a SIPP gives you direct control over your investments — and with that control comes the potential to significantly grow your retirement savings.
For the wider cluster covering core SIPP rules, provider choice and workplace comparisons, use the main SIPP hub.
This guide covers everything you need to know to manage a SIPP effectively.
What Is a SIPP?
A SIPP is a type of personal pension that allows you to build up a pension pot while choosing your own investments. It works like any other registered pension scheme for tax purposes:
- Contributions attract income tax relief at your marginal rate
- Growth is free from capital gains tax and income tax
- You can access benefits from age 55 (rising to 57 in April 2028)
- 25% of the pot can be taken tax-free (up to £268,275 lifetime limit)
- The rest is taxed as income when withdrawn
What Can You Invest In?
Allowed SIPP Investments
| Investment type | Notes |
|---|---|
| UK listed shares | Directly via stockbroker |
| Overseas shares | Available on most platforms |
| Investment trusts | Closed-ended funds, listed on LSE |
| ETFs (Exchange-Traded Funds) | Low-cost index trackers |
| Unit trusts / OEICs | Managed funds, active or passive |
| Government bonds (gilts) | UK government debt |
| Corporate bonds | Company debt |
| Cash | Bank/savings accounts within SIPP |
| Commercial property | Offices, shops, factories — not residential |
NOT Allowed in a SIPP
- Residential property (buy-to-let, holiday lets)
- Life insurance policies
- Fine wine, art, antiques, jewellery
- Tangible moveable property (unless HMRC-exempt)
- Loans to yourself or connected persons
Full SIPPs vs Low-Cost SIPPs
Full SIPPs (offered by specialist firms) allow commercial property and esoteric assets. Annual costs typically £500–£1,500.
Low-cost SIPPS (offered by investment platforms like Vanguard, Hargreaves Lansdown, AJ Bell, II) focus on funds, ETFs, and shares. Most investors don’t need a full SIPP.
Choosing a SIPP Provider
| Provider | Best for | Annual platform fee | Notes |
|---|---|---|---|
| Vanguard | Low-cost passive index investing | 0.15% (cap £375) | Own funds only |
| iWeb | Large lump sums (low % fee) | £100 flat | Trades £5 each |
| Interactive Investor (ii) | Regular investors | £143.88–£239.88/yr flat | Good for larger pots |
| AJ Bell | Balance of choice and cost | 0.25% (capped) | Wide fund range |
| Hargreaves Lansdown | Largest range, best service | 0.45% (capped at £200) | Expensive for large pots |
| Pensionbee | Simple, fully managed | 0.5–0.95% | Good if you want simplicity |
Key principle: For large pots (£100,000+), flat fee platforms (iWeb, ii) are typically cheaper than percentage fee platforms.
The Charges Audit
Always calculate the total annual cost before opening or staying with a SIPP:
- Platform fee (annual charge as % or flat fee)
- Fund charge (OCF — Ongoing Charges Figure of the fund)
- Transaction costs (dealing fees to buy/sell)
Example: 0.45% platform + 0.20% fund OCF = 0.65%/year. On a £200,000 pot, that is £1,300/year, every year.
SIPP Contribution Rules 2026/27
| Scenario | Maximum annual contribution |
|---|---|
| Employed/self-employed with earnings | Lower of earnings or £60,000 |
| No earned income | £3,600 gross (£2,880 net) |
| MPAA triggered (in flexible drawdown) | £10,000 |
Carry Forward
If you contributed less than the Annual Allowance in the past three years, you can “carry forward” unused allowance — but you must use the current year’s allowance first, and you must have been a member of a pension scheme in those years. Carry forward is calculated on the gross amount, not the net contribution.
Higher Rate Tax Relief — Don’t Miss It
Higher rate taxpayers must claim the extra relief via Self-Assessment. The pension provider only adds basic rate (20%) relief automatically.
| Taxpayer | Effective cost of £10,000 contribution |
|---|---|
| Basic rate (20%) | £8,000 net cost |
| Higher rate (40%) | £6,000 net cost |
| Additional rate (45%) | £5,500 net cost |
| Scottish top rate (48%) | £5,200 net cost |
Investment Strategy Inside a SIPP
For Long-Term Growth (20+ Years to Retirement)
A simple multi-asset portfolio is usually appropriate:
- Global equity index tracker (e.g., MSCI World ETF, Vanguard FTSE All-World): long-term core
- UK equity tracker (optional UK home bias)
- Bonds (as a % to reduce volatility as retirement approaches)
A common rule of thumb: hold (100 – your age)% in equities. A 40-year-old: 60% equities.
Lifestyling
Many workplace pensions automatically “lifestyle” — shift from equities to bonds/cash as you approach retirement. With a SIPP, you manage this yourself. If you plan to go into drawdown (rather than buy an annuity), you may not want to go very low on equities — you need growth to sustain 20–30+ years of income.
Low-Cost Strategy
Research by Vanguard and others consistently shows that total annual investment costs below 0.5% outperform active funds in the long run. A portfolio of:
- Vanguard FTSE All-World UCITS ETF (0.22% OCF)
- Vanguard UK Government Bond Index (0.12% OCF)
…costs less than 0.25% all-in on the fund side, before platform fees.
Pension Consolidation Into a SIPP
If you have multiple old workplace pensions, consolidating into a SIPP may make sense:
- Simpler management
- Potential lower charges
- Access to wider investment choice
Before Consolidating, Check
| Check | Why it matters |
|---|---|
| Does the old scheme have protected pension age of 55? | Transferring may remove this |
| Does the old scheme have guaranteed annuity rates (GARs)? | These can be very valuable — don’t give them up without advice |
| Is this a defined benefit (final salary) scheme? | Transfers over £30,000 require regulated financial advice |
| Are there exit penalties? | Older pensions sometimes have penalty charges |
Transferring a defined benefit pension is generally irreversible. The Pension Regulator strongly advises that DB→DC transfers are usually only appropriate in specific circumstances.
SIPP in Drawdown
From age 55 (57 from April 2028) you can move a SIPP into drawdown. See the related Pension Drawdown Income Tax Planning guide for full detail on taking income tax-efficiently.
Key drawdown facts:
- No need to purchase an annuity
- Remaining fund stays invested (continues to grow or fall with markets)
- No minimum or maximum withdrawal (you choose)
- Flexible income — take more or less each year
- On death, remaining fund passes to nominated beneficiaries
SIPP vs Other Pension Options
| Feature | SIPP | Workplace pension | Annuity |
|---|---|---|---|
| Investment control | Full | Limited (few funds) | None |
| Flexibility | High | Medium | None |
| Charges | Varies | Often employer-subsidised | Built in |
| Death benefits | Flexible | Varies | Limited |
| Employer contributions | No | Yes | N/A |
If you have an employer offering pension contributions, always maximise those first — employer contributions are essentially free money. Supplement with a SIPP for additional savings.
Common SIPP Mistakes
| Mistake | Impact |
|---|---|
| Not claiming higher rate relief via Self-Assessment | Leaves 20% tax relief unclaimed |
| Paying in over the Annual Allowance | 40%+ annual allowance charge on excess |
| Triggering MPAA early (drawdown while still working) | Caps future contributions at £10,000 |
| Holding excess cash (not invested) | Inflation erodes value — cash in SIPP rarely pays competitive rates |
| Ignoring charges over time | Difference of 0.5%/year in costs = £30,000+ on £200k pot over 20 years |
| Not nominating a beneficiary | Pension goes to estate and may incur more tax |
