SIPP vs. Workplace Pensions

2026-02-145 min read

Should you stick with your employer or go it alone? The pros and cons explained.

The Big Two

Most private retirement savings in the UK sit in one of two buckets:

  1. Workplace Pension: Set up by your employer.
  2. SIPP (Self-Invested Personal Pension): Set up by you, privately.

Which one is better? It usually depends on "Free Money" vs "Control".

Workplace Pensions: The Default Choice for a Reason

If you are employed, this is almost always the first place to put your money.

The Smart Way to Save

Your employer contributes too! By law, they must contribute at least 3% of your qualifying earnings, but many pay much more. Never say no to free money.

Pros:

  • Employer Contribution: Free cash on top of your salary.
  • Salary Sacrifice: Many schemes reduce your NI bill (saving you 8% or 2%).
  • Done for You: Automatic enrolment and investment management.

Cons:

  • Limited Choice: You usually only have a few funds to choose from.
  • Higher Fees?: Some older schemes have high management charges (though a 0.75% cap applies to defaults).

SIPP: For The Control Freak (In a Good Way)

A SIPP is a personal pot of money that follows you, not your job. You have total control over where it is invested (Shares, ETFs, Funds).

Pros:

  • Unlimited Choice: Invest in almost anything (Apple, Vanguard, UK Gilts).
  • Consolidation: Combine 5 old workplace pots into one view.
  • Low Fees: Modern providers (like Vanguard, AJ Bell, Interactive Investor) can be very cheap for larger pots.

Cons:

  • You Do The Work: You must choose your investments.
  • No Employer Match: Unless your employer agrees to pay into your SIPP (rare), you miss out on their contribution.

Which order should I prioritise?

For most people, the "Waterfall" method works best:

  1. Max out the Workplace Match: Pay in whatever is needed to get the maximum contribution from your boss. That is a guaranteed 100% (or similar) return instantly.
  2. Pay High Interest Debt: Clear expensive credit cards or loans.
  3. Consider a SIPP: For any extra savings on top, a SIPP allows you to choose better/cheaper funds.

Guidance, not advice.

Investment values can go down as well as up. Ensure you understand the fees of any platform you switch to.
