SIPP for self-employed — how to choose.

A Self-Invested Personal Pension is the most common pension vehicle for self-employed workers. It offers flexible contributions, broad investment choice, and full portability. Here's what matters when choosing one.

Why a SIPP suits the self-employed

A SIPP — Self-Invested Personal Pension — is a personal pension that gives the holder control over investment choices and contribution timing. Unlike workplace pensions, which are set up by an employer with limited fund options, a SIPP is chosen and managed by the individual.

For self-employed workers, this flexibility is particularly relevant. Self-employed income is often irregular — a freelance designer might earn £8,000 one month and £2,000 the next. A SIPP accommodates this: contributions can be made monthly, quarterly, annually, or irregularly. There is no minimum contribution frequency, and most providers allow contributions to be paused and restarted without penalty.

Investment choice is the other advantage. A typical workplace pension offers 10–30 funds. A SIPP typically offers thousands — including index trackers, ETFs, individual shares, investment trusts, and bonds. For a self-employed person who wants to invest in a simple global index tracker at the lowest possible cost, a SIPP makes this straightforward.

Key factors in choosing a SIPP

The differences between SIPP providers come down to a few variables:

Total annual cost. This is the platform fee (charged by the provider) plus the ongoing charges figure (OCF) of the funds held. A low-cost SIPP with a global index tracker might cost 0.15% platform fee + 0.22% fund OCF = 0.37% total. A more expensive provider with an actively managed default fund might cost 0.45% + 0.80% = 1.25% total. Over 25 years on a £100,000 pot, that gap compounds to over £80,000.

Fee model. Some providers charge a percentage of assets; others charge a flat annual fee (e.g., £50–£120 per year regardless of pot size). Flat-fee providers become more competitive as pot size grows. For pots under £50,000, percentage-based providers are usually cheaper. The provider comparison page shows the cost breakdown.

Fund range. For most self-employed savers, a single global equity index tracker is sufficient. If the provider offers this at a low OCF, the range of other funds is largely irrelevant. For those wanting more exotic options (individual shares, investment trusts, bonds), a broader range matters.

Drawdown options. At retirement, the SIPP needs to support income drawdown — the ability to take flexible income from the pot while the rest remains invested. Most modern SIPPs include this as standard, but some older or low-cost providers charge extra for drawdown setup or administration. The drawdown guide covers the mechanics.

Transfer ease. Self-employed workers who have had previous employment may have old workplace pensions to consolidate. A SIPP that accepts transfers in-specie (without selling and rebuying holdings) and does so without fees is preferable.

NEST for self-employed: the alternative

NEST (National Employment Savings Trust) is the government-backed workplace pension scheme designed to support auto-enrolment. It is primarily an employer scheme, but self-employed individuals can also join.

NEST charges 0.3% AMC and a 1.75% contribution charge on each payment in. The contribution charge is unusual — it reduces the initial value of each contribution by 1.75% before it is invested. On a £1,000 contribution, £17.50 is deducted, and £982.50 is invested.

For small, regular contributions over a long period, the contribution charge is relatively minor — the low ongoing AMC compensates. For large lump-sum contributions, the 1.75% charge is more significant and may make NEST less competitive than a low-cost SIPP with no contribution charge.

NEST's investment options are limited to a handful of retirement date funds and a few alternatives (ethical, Sharia). There is no option to hold individual shares, ETFs, or choose from a wide fund range.

For a self-employed person who wants simplicity and low ongoing costs, and is contributing modest regular amounts, NEST is a reasonable option. For anyone wanting investment flexibility or making larger contributions, a SIPP is typically preferable.

Contribution timing: tax year deadline

Pension contributions receive tax relief in the tax year they are made. The tax year runs from 6 April to 5 April. A contribution made on 4 April counts in the current tax year; a contribution made on 6 April counts in the next.

For self-employed workers claiming higher-rate tax relief, the timing interacts with self-assessment. The pension provider automatically claims basic-rate relief (20%) from HMRC. Higher-rate (40%) and additional-rate (45%) relief is claimed through the self-assessment tax return for the year the contribution was made.

This means a contribution made in March 2026 (tax year 2025/26) is claimed on the 2025/26 self-assessment return, typically filed by 31 January 2027. The additional relief appears as a reduction in the tax bill or a refund.

For self-employed workers with variable income, the end of the tax year is often the best time to make pension contributions — by then, annual profits are clearer, and the contribution can be sized accordingly.
