Workplace Pension vs SIPP: Which Should You Use?
A workplace pension comes with your employer's money attached. A SIPP gives you choice and control. People often frame this as a choice between the two, but the sensible answer for most is an order of priority, and it starts with never turning down the employer contribution.
What each one is
A workplace pension is the scheme your employer enrols you into automatically. Under auto-enrolment rules, a minimum of 8% of your qualifying earnings (the band between £6,240 and £50,270 in 2026/27) must go in, made up of at least 3% from your employer, with the rest from you including tax relief (source: GOV.UK auto-enrolment review 2026/27). Your money lands in a default investment fund unless you choose otherwise.
A SIPP (self-invested personal pension) is a pension you open yourself with an investment platform. Nobody pays in except you (and the taxman, via tax relief). In exchange you choose from a far wider menu: funds, index trackers, shares, investment trusts.
The comparison that matters
| Workplace pension | SIPP | |
|---|---|---|
| Employer money | Yes, 3% minimum, often more | No |
| Tax relief | Yes | Yes |
| Charges | Default fund capped at 0.75% a year | Varies by platform; can be cheaper or dearer |
| Investment choice | Limited fund list | Very wide |
| Effort required | None, it runs itself | You pick and manage investments |
| Salary sacrifice possible | Often | No |
Rule one: bank the employer money first
The employer contribution is the single best return available in pensions. Pay in enough to get every pound of match your employer offers before a SIPP even enters the conversation. If your employer matches beyond the 3% minimum, take all of it. Nothing a SIPP offers beats free employer money.
If your scheme offers salary sacrifice, that tips things further towards the workplace pension, because sacrifice saves National Insurance and SIPP contributions cannot.
You can have both
There is no rule against holding a workplace pension and a SIPP at the same time. The £60,000 annual allowance covers everything going into all of them combined. Many people keep the workplace scheme for the match and use a SIPP for extra saving or for gathering up old pots.
When a SIPP earns its place
- You have maxed the match. Contributions beyond what your employer will match are a fair fight between your scheme and a SIPP, and the SIPP may win on cost or choice.
- You have old pensions scattered about. A SIPP is a common home for combining old pots, putting everything where you can see it.
- You want investments your scheme does not offer. Workplace default funds are deliberately middle-of-the-road. If you have the interest and the patience, a SIPP lets you build something more deliberate.
- You are self-employed. No employer, no workplace scheme, so a SIPP (or a personal pension) is the standard route.
Watch the charges in both directions
Workplace default funds are capped at 0.75% a year, and many large schemes charge well under that. SIPP costs come in different shapes: some platforms charge a percentage of your pot, others a flat monthly fee, plus the cost of the investments themselves. A flat fee tends to suit bigger pots and a percentage fee smaller ones, so run your own numbers rather than assuming the SIPP is automatically cheaper. A percentage point of extra charges compounds into a serious dent over decades.

Each employer enrols you into their own scheme, which is how people end up with a trail of small pots. Your old workplace pensions keep growing (and keep charging) after you leave, they just stop receiving contributions. A SIPP can act as the permanent home that follows you from job to job: each time you move on, you can transfer the old pot in. Check for exit fees or valuable guarantees before transferring anything, and see our guide to finding and combining old pensions first.
The short version
- Take every pound of employer match in your workplace pension. Always.
- Use salary sacrifice if your employer offers it.
- Saving more on top? Compare your workplace scheme's charges and funds against a SIPP, and use whichever serves you better.
- Self-employed? A SIPP is the obvious starting point.
