Master trusts have become the dominant vehicle for workplace pension saving in the UK since auto-enrolment began in 2012. If you joined your employer’s pension scheme in the last decade and your employer is a small or medium-sized business, there is a good chance you are in a master trust. Understanding what that means for your money, your governance, and your rights is worth knowing.
What Sets Master Trusts Apart
| Feature | Single-employer trust | Master trust |
|---|---|---|
| Who sets it up | One employer, for its own staff | Professional trustees, shared by many employers |
| Number of employers | One | Many (can be thousands) |
| Trustees | Employer-appointed + member-nominated | Professional board; independent of any employer |
| TPR authorisation required | No (but regulated) | Yes — mandatory since 2021 |
| Common for | Large established organisations | Auto-enrolment for small/medium employers |
The Major UK Master Trusts
| Provider | Key facts | Charge structure |
|---|---|---|
| NEST | Government-backed; open to any employer; 12m+ members | 0.3% AMC + 1.8% on contributions |
| The People’s Pension | B&CE charitable trust; widely used by small employers | 0.5% AMC |
| NOW: Pensions | Danish parent company; strong in hospitality/retail | ~0.3% AMC |
| Smart Pension | Tech-forward; strong app and member experience | Tiered; typically 0.3–0.5% |
| Cushon | ESG focus; suitable for sustainability-conscious employers | 0.49% AMC |
All of the above are TPR-authorised master trusts.
TPR Authorisation — What It Means for You
The Pension Schemes Act 2021 introduced mandatory TPR authorisation for all master trusts. To receive authorisation, a master trust must demonstrate:
- Fit and proper trustees (criminal record checks, competence requirements)
- Sound financial sustainability
- A robust business strategy
- Adequate systems and processes for administration
- Scheme documentation that meets TPR standards
Unauthorised master trusts cannot legally operate. This provides a baseline assurance that did not exist before 2021.
What Happens if a Master Trust Fails
Master trusts must hold ring-fenced capital — the “scheme funder continuity strategy” — sufficient to wind up the trust and transfer members to an authorised alternative scheme if needed. This is not FSCS protection, but it does mean members cannot be left without their pot.
TPR has intervention powers to:
- Appoint independent trustees
- Supervise a wind-up
- Ensure the transfer of members to an authorised master trust
In practice, no large UK master trust has failed in a way that harmed member assets.
NEST — The Government-Backed Default
NEST was set up by the government to ensure every UK employer had access to a qualifying pension scheme for auto-enrolment. Key points:
- Open to any employer and any worker — no employer can be refused
- Contribution levels: 8% total minimum (5% employee, 3% employer of qualifying earnings) under auto-enrolment rules
- Charges: 0.3% AMC + 1.8% on each contribution. For a £10,000 pot and no new contributions, the 1.8% contribution charge is not relevant — only the 0.3% AMC applies
- Self-employed can also join NEST directly
Is Your Employer’s Master Trust a Good Choice?
Factors to consider:
- Charges: All charges should be clearly stated; compare against the 0.75% auto-enrolment charge cap
- Default fund: Check the lifestyling approach and whether it aligns to your planned retirement age and income strategy
- Online tools: Quality of member portal, app, and projection tools varies significantly
- Transfer options: Can you transfer in old pensions? Can you transfer out freely when you leave the employer?
You can also open a SIPP alongside your master trust to supplement contributions or take more control of investments.
