SIPP vs Workplace Pension UK 2026: Which Should You Use?

How auto-enrolment workplace pensions and Self-Invested Personal Pensions compare on fees, contributions, investment choice, and tax relief.

Last reviewed: 11 May 2026.

What is a workplace pension?

A workplace pension is a pension arranged by your employer. Under auto-enrolment rules in place since 2012, every UK employee aged 22 or over earning above £10,000 a year must be enrolled in their employer's qualifying workplace pension. You can opt out (with consequences) but you cannot opt out and demand the employer contribution be paid as cash.

Minimum contributions under auto-enrolment:

• Employee: 5% of qualifying earnings (gross, then 20% tax relief added by the scheme).
• Employer: 3% of qualifying earnings.
• Qualifying earnings: Earnings between £6,240 and £50,270 (lower and upper thresholds for 2025-26).
• Many employers contribute more than the 3% minimum, sometimes matching employee contributions up to 5% to 10%. This is the most valuable feature of a workplace pension.

Workplace pensions can be either defined contribution (DC, the modern norm) or defined benefit (DB, mostly historic in the public sector and a few private-sector schemes). This guide focuses on DC; DB is a different product with its own rules.

What is a SIPP?

A SIPP is a Self-Invested Personal Pension. It is a pension you open with a provider yourself, fund yourself, and choose investments within yourself. Tax relief works the same way as a workplace pension: contributions get 20% relief at source (basic rate), with higher-rate or additional-rate relief reclaimed via your tax return if applicable.

Inside a SIPP you can typically invest in:

• UK and international shares listed on recognised exchanges.
• Investment funds (OEICs and unit trusts).
• Exchange-traded funds (ETFs).
• Investment trusts.
• UK gilts and corporate bonds.
• Commercial property (in some SIPPs, with specialist providers).
• Cash and money market funds.

Most retail SIPPs do not allow residential property, hedge funds, or unlisted shares. Specialist "full" SIPPs offer wider ranges with higher fees.

Cost comparison

Workplace pension fees vary widely. Some master-trust schemes are very competitive (around 0.30% to 0.40% all-in); some older legacy schemes can be 1% or more. Check your annual benefit statement for the fee.

Tax relief: how it works

Both workplace pensions and SIPPs offer tax relief on contributions at your marginal rate. The mechanics differ slightly:

Relief-at-source (most SIPPs and some workplace schemes)

You pay in net of basic-rate tax. The provider claims 20% from HMRC and adds it to the pot. Higher-rate (40%) and additional-rate (45%) taxpayers claim the extra 20% or 25% through their Self Assessment tax return.

Net pay arrangement (most workplace pensions)

Contributions are deducted from your gross salary before income tax is calculated. You automatically get relief at your full marginal rate. No tax return needed. Cleaner for higher-rate taxpayers.

Salary sacrifice (some workplace pensions)

You agree to a lower gross salary in exchange for an increased employer pension contribution equal to the cut. This saves both income tax and National Insurance for the employee, and saves employer NI for the company. Many employers pass the NI saving back to the employee as additional pension contribution. Salary sacrifice cannot reduce gross pay below National Minimum Wage.

Salary sacrifice is materially more efficient than the other two methods for higher-rate taxpayers. If your employer offers it, use it.

Annual allowance

The annual allowance is the maximum that can be contributed to all your pensions combined (employee + employer + tax relief) in a single tax year without an annual allowance tax charge. For 2025-26 the standard annual allowance is £60,000.

For very high earners, the allowance tapers down to £10,000 minimum when adjusted income exceeds £260,000. Anyone who has triggered the Money Purchase Annual Allowance is capped at £10,000 a year for DC contributions.

You can use unused allowance from the previous three tax years if you have one or more of those years' membership in a pension scheme. This is "carry forward".

When a SIPP makes sense as an addition

• Your workplace pension's investment options are limited and don't include a global equity tracker, gilts, or other components you want.
• Your workplace pension fees exceed 0.6% all-in, where a SIPP would be materially cheaper.
• You want to consolidate old workplace pensions from previous employers into one place. SIPPs are commonly used as a transfer destination.
• You're self-employed or have variable freelance income on top of PAYE work - a SIPP gives you a single retirement vehicle you control.
• You're a higher-rate taxpayer and your workplace scheme uses relief-at-source rather than net pay, making a SIPP with relief-at-source no worse but with better fund choice.
• You've already contributed up to (or beyond) the employer match in your workplace pension and have additional money to contribute beyond that level.

When workplace alone is enough

• Your workplace pension is a master-trust scheme with all-in fees under 0.50% and includes a global equity tracker default fund.
• Your employer matches contributions generously (e.g., 6% to 10%), and you're already maxing the match.
• You don't want the admin of running a separate SIPP and would prefer to focus your investing energy on one wrapper.
• Your other tax-advantaged accounts (ISA, LISA) are not yet maxed and would be a better use of additional contribution capacity.

Transfers

You can transfer pensions between workplace schemes and SIPPs in most cases. Restrictions and considerations:

• Defined benefit: Transfers out of a defined benefit pension worth over £30,000 require regulated financial advice. Most DB transfers are not in the saver's interest because of the loss of guaranteed lifetime income.
• Guaranteed Annuity Rates: Some older personal pensions have GARs (often 7% to 10%) which are valuable and lost on transfer. Always check before transferring an old pension.
• Employer match: Transferring your workplace pension to a SIPP usually requires you to leave the employer scheme. Continued employment usually triggers re-enrolment, so the employer contribution continues into the workplace scheme. Some employers allow ongoing contributions to a personal pension instead - check policy.
• Exit fees: Some old personal pensions have exit penalties on transfer (capped at 1% for ages 55+ by FCA rules).

Frequently Asked Questions

Can I have both a SIPP and a workplace pension?

Yes. Many people do. Your contributions to both count towards the same annual allowance (£60,000 in 2025-26).

Is a SIPP riskier than a workplace pension?

Not inherently. The risk depends on what you invest in inside each. A workplace pension's default fund is usually a moderate-risk diversified mix; a SIPP can be invested similarly or more aggressively/conservatively depending on your choices.

Can my employer contribute to my SIPP?

Yes, in principle, but most employers won't because their auto-enrolment compliance is built around their chosen workplace scheme. Some employers allow it after explicit request, particularly for senior staff.

What if I leave my employer?

Your workplace pension stays where it is - it doesn't disappear. You can leave it (and continue to benefit from market growth and any ongoing fees), transfer it to your next employer's scheme, or transfer it to a SIPP. There is no rush to act.

Can I access a SIPP at 55?

Yes, but the minimum pension age is rising to 57 from April 2028. The same rules apply to SIPPs and workplace pensions.
