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.
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 from 6 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- The rest is taxed as income when withdrawn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
Several major platforms changed their charging structures during 2026 — figures below are published rates as of September 2026; confirm current terms directly with the 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) | One-off account opening fee | Check current dealing charges |
| Interactive Investor (ii) | Regular investors | Core £5.99/month, Plus £14.99/month, Premium £39.99/month | One fee now covers ISA, SIPP and trading account (since Feb 2026 repricing) |
| AJ Bell | Balance of choice and cost | 0.25% on funds (tiering down above £250k) | Shares/ETFs capped at £10/month |
| Hargreaves Lansdown | Largest range, best service | 0.35% (first £250k), reducing above — cut from 0.45% in March 2026 | Shares/ETFs capped at £12.50/month |
| Pensionbee | Simple, fully managed | 0.50–0.95% (halved above £100k) | Good if you want simplicity |
Key principle: For large pots (£100,000+), flat fee platforms (iWeb, ii) are typically cheaper than percentage fee platforms — but compare current tiers against your actual pot size, since several providers repriced in 2026.
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: 0.35% platform + 0.20% fund OCF = 0.55%/year. On a £200,000 pot, that is £1,100/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 |
| Tapered annual allowance | Reduces by £1 per £2 of adjusted income above £260,000 (where threshold income exceeds £200,000), down to a £10,000 floor at £360,000 adjusted income |
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 a protected pension age below 55/57? | 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 6 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 |
