Can I Have a SIPP and a Workplace Pension Together?

Yes. Most UK workers eventually hold both — an active workplace pension funded through their employer plus a self-directed SIPP they’ve opened themselves. There’s no rule against contributing to multiple pensions in the same tax year. The constraint is the £60,000 annual allowance for 2026/27 which applies to your combined contributions across all pensions (yours, your employer’s and HMRC’s tax relief), plus the tapered annual allowance for high earners.

This is how the two products combine and where the trade-offs land.

What each product does

Workplace pension:

• Set up by your employer.
• You’re auto-enrolled (minimum 8% combined contribution).
• Employer contributes alongside you (typically 3–5%+ of salary).
• Limited investment choice via the scheme’s default fund or fund menu.
• Fees usually 0.30–0.75% per year.
• Salary sacrifice often available for additional tax/NI efficiency.

SIPP (Self-Invested Personal Pension):

• You open it yourself, with a provider of your choice.
• You direct the investments — funds, ETFs, individual shares, bonds.
• Same tax wrapper rules as the workplace pension.
• Platform fees range from £10/month flat to 0.45% per year, plus dealing fees.
• No employer contribution.

Both get the same tax treatment: contributions reduce taxable income (or get tax relief added); growth is tax-free; 25% can be taken as a tax-free lump sum at retirement; remaining 75% is taxable income when drawn.

How the £60,000 annual allowance works across both

The annual allowance is your maximum contribution across all pensions combined in a tax year while still getting tax relief.

For 2026/27:

• Standard annual allowance: £60,000.
• This includes: your contributions + employer contributions + HMRC tax relief.
• Excess contributions don’t get relief and may be subject to an annual allowance charge.

Tapered annual allowance for high earners:

• Adjusted income above £260,000 starts reducing the allowance by £1 for every £2 over.
• Minimum allowance: £10,000 (reached at £360,000+ adjusted income).

MPAA (Money Purchase Annual Allowance):

• Triggered by flexibly accessing a DC pension (taking taxable income beyond 25% tax-free).
• Caps DC contributions at £10,000 per year, no carry-forward.

The detail is at HMRC: pension annual allowance.

Why use both?

Three main reasons:

1. Workplace gets the employer match

Most workplace pensions match your contributions up to some level. A 3-and-3 match (3% employer if you contribute 3%) doubles your contribution’s effective value — a guaranteed 100% return on the matched portion.

The match is free money — there’s no SIPP equivalent. Always capture the full match before contributing to a SIPP.

2. SIPP for investment choice

If your workplace scheme has limited fund options, high fees on its choice funds, or a default fund you’re not happy with, a SIPP gives you:

• Wider fund choice (Vanguard, iShares, BlackRock, Fidelity etc.).
• Individual shares and ETFs if you want.
• Lower fees on broad index funds (sometimes 0.10% on a SIPP vs 0.50% on the workplace default).

For investors who want to take active control, the SIPP supplements the workplace.

3. Consolidation vehicle for old workplace pensions

When you change jobs, you typically leave a workplace pension behind. Over a career you may accumulate 5–10 old pots.

A SIPP can be the destination for consolidating these — transfer the old workplace DC pensions into the SIPP, reduce admin overhead, and unify investment management.

(DB pensions should not be transferred to a SIPP without regulated advice — they’re too valuable to give up casually.)

The contribution prioritisation

For most UK earners, the order of priority is:

1. Workplace match: contribute enough to capture all employer matching.
2. High-interest debt: clear before discretionary pension contributions.
3. Additional workplace contributions (if salary sacrifice is available and the workplace fund range is OK).
4. SIPP contributions for further pension building beyond the workplace.

The reason salary sacrifice in the workplace often beats SIPP contributions:

• Salary sacrifice saves employee NI (currently 8% main rate).
• Salary sacrifice saves employer NI (15%) — some schemes pass this into your pension.
• Net effective relief can be higher than a SIPP’s relief-at-source mechanism.

If the workplace fund range is restrictive, you can still do the workplace contributions for the NI saving and use a SIPP for “extra” beyond what the workplace offers.

How tax relief flows in each

The mechanism for relief differs slightly:

Workplace pension via salary sacrifice:

• Contribution comes out of gross salary before income tax and NI.
• All relief is automatic.

Workplace pension via net pay arrangement:

• Contribution comes out before income tax (after NI).
• Income tax relief automatic; NI not saved.

Workplace pension via relief at source:

• Contribution comes from net pay.
• Provider claims basic-rate relief (20%) into the pension.
• Higher/additional rate reclaimed via Self Assessment.

SIPP:

• Always relief at source.
• Provider claims basic-rate relief.
• Higher/additional rate reclaimed via Self Assessment.

For higher-rate taxpayers using a SIPP, filing Self Assessment to claim the extra 20% relief is essential. Without it, the SIPP is materially less tax-efficient than a salary-sacrifice workplace contribution.

Consolidating old workplace pensions into a SIPP

The process for combining old workplace pensions into a SIPP:

1. Identify the old pensions — request statements from previous employers or use the Pension Tracing Service.
2. Confirm they’re DC, not DB. DB transfers require regulated advice for transfers above £30,000.
3. Choose a SIPP provider. Compare platform fees, fund range, dealing costs.
4. Initiate the transfer through the SIPP provider. They contact the old workplace pension scheme.
5. Wait — transfers can take 4–12 weeks, sometimes longer.
6. Invest the consolidated pot in your chosen funds.

After consolidation, you have a single pension pot you can manage easily. The current workplace pension stays separate (it’s still receiving live contributions) — you can consolidate that one too when you eventually leave the employer.

Worked example: 35-year-old with workplace + SIPP

Sarah is 35, earns £70,000, on a workplace pension with 5% employer match (so 5+5 = 10% total).

Her contribution structure:

• Workplace pension (via salary sacrifice): £7,000/year employee (10% of salary), £3,500/year employer (5%) = £10,500/year total via workplace.
• SIPP: £200/month = £2,400/year + 25% relief at source = £3,000/year gross.
• Total annual pension contributions: £13,500.
• Annual allowance: £60,000 — well within.

After 25 years (assuming 5% real returns):

• Workplace pension: ~£500,000.
• SIPP: ~£140,000.
• Combined: £640,000.

She can keep the workplace pension separate or transfer it into the SIPP when she eventually leaves the employer. Either way, both pots contribute to her retirement plan.
