NEST vs Other Master Trust Workplace Pensions: Comparing Fee Structures (2026)
NEST and commercial master trusts like The People's Pension or Smart Pension all meet the same auto-enrolment minimums, but their fee structures differ in ways that meaningfully affect your retirement pot. Here's how to compare them.
What a master trust actually is
A master trust is an occupational pension scheme used by multiple, unconnected employers, rather than each employer setting up and running its own dedicated pension scheme. This model became especially important after automatic enrolment made workplace pension provision compulsory for virtually every employer, since setting up an individual trust-based scheme is impractical for most small and medium businesses. Instead, they join an existing, professionally governed master trust.

Open Auto-Enrolment calculatorNEST (National Employment Savings Trust) is itself a master trust, but a distinctive one: it was specifically established by government to guarantee that every UK employer, regardless of size or sector, would have access to a workplace pension scheme for auto-enrolment purposes, with a public service obligation to accept any employer that wants to use it.
Fee structures compared
Master trusts (including NEST and its commercial competitors, such as The People's Pension, Smart Pension, and various others) typically use one or a combination of these charging structures:
| Charge type | How it works |
|---|---|
| Annual management charge (AMC) | A percentage of your total fund value, deducted annually (e.g., 0.3%-0.5%) |
| Contribution charge | A percentage deducted from each new contribution as it goes in (e.g., 1.8% historically used by NEST on new contributions) |
| Combined structure | Both an AMC and a contribution charge applied together |
| Flat annual fee | A fixed pound amount per year, regardless of fund size (less common for workplace default schemes) |
Worked example: two fee structures over a career
Consider two hypothetical master trusts, both receiving identical annual contributions of £3,000, growing at an assumed 5% investment return before charges, over a 30-year working life.
| Structure | Fee details | Illustrative pot value after 30 years |
|---|---|---|
| Contribution charge + low AMC | 1.8% charge on contributions in, 0.3% AMC | Slightly reduced growth, front-loaded cost |
| Pure AMC, no contribution charge | 0.5% AMC only | Different total cost profile — can be higher or lower depending on the specific rates and time horizon |
The precise outcome depends heavily on the exact rates each scheme charges and how long the money remains invested — money contributed early in a career and invested for decades is affected far more by an ongoing AMC than a one-off contribution charge, while the reverse can be true for shorter time horizons or later-career contributions.
The auto-enrolment charge cap
To protect employees defaulted into a workplace pension (rather than actively choosing one), the government imposes a charge cap of 0.75% a year on the default investment fund of qualifying automatic enrolment schemes. This cap applies to the default fund specifically — schemes can still offer higher-charging fund options for employees who actively choose to invest outside the default, but the fund most people are automatically placed into cannot exceed this cap.
| Feature | Detail |
|---|---|
| Charge cap | 0.75% per year, on the default fund |
| Applies to | Default fund of qualifying auto-enrolment schemes |
| Does it cover contribution charges too? | The cap calculation methodology accounts for combined charge structures to keep the effective annual cost within the cap threshold |
Why employees usually can't choose the scheme themselves
For the vast majority of employees, the employer decides which workplace pension provider (including which master trust, if any) to use for automatic enrolment — this is a business decision made once, applied to the whole eligible workforce, rather than a per-employee choice. Employees typically retain the ability to:
- Choose from a range of investment fund options within whatever scheme the employer has selected (e.g., ethical funds, higher-growth equity funds, lower-risk funds).
- Opt out of the scheme entirely, though this forfeits the valuable employer contribution.
- Separately open and contribute to their own personal pension or SIPP alongside the workplace scheme, for anyone who wants more control over provider choice and fees for additional savings.
What to actually check as an employee
While you generally can't change your workplace scheme provider individually, it's still worth understanding your specific scheme's fee structure, since it affects how much of your — and your employer's — contributions ultimately reach your retirement pot:
- Find your scheme's annual statement or member portal and identify the specific AMC and/or contribution charge that applies.
- Check whether you're in the default fund or have actively chosen an alternative — default funds are subject to the 0.75% cap, but chosen alternatives may not be.
- Compare against a personal pension or SIPP if you're considering directing additional voluntary contributions outside your workplace scheme, since a low-cost personal SIPP can sometimes offer a more competitive fee structure for extra savings beyond the employer-matched minimum.

Frequently asked questions
What is a master trust?
A master trust is a multi-employer occupational pension scheme, regulated and authorised by The Pensions Regulator, used by many small and medium employers to meet their automatic enrolment duties without setting up their own individual company pension scheme.
Is NEST different from other master trusts?
NEST (National Employment Savings Trust) is itself a master trust, but a public body one, set up by government specifically to ensure every employer has access to a pension scheme for auto-enrolment, regardless of size. It sits alongside commercial master trusts as one option among several.
Do all master trusts charge the same fees?
No. Fee structures vary between master trusts — some charge a percentage of your fund (an annual management charge), some add a contribution charge on money going in, and some combine both, meaning identical contributions can grow into meaningfully different pot sizes over a career depending on which master trust an employer chooses.
Can employees choose their own workplace pension provider?
Generally no — the employer selects the workplace pension scheme (including which master trust, if any) for all eligible staff, though employees can typically choose their own investment fund options within that scheme, and can separately open their own personal pension or SIPP if they want more control.
Why does the fee structure matter so much for a workplace pension held for decades?
Because workplace pensions are typically held for 20-40+ years, even a small percentage-point difference in annual charges compounds significantly over such a long period, similar to the effect of fees on any other long-term investment.
