NEST vs qualifying workplace pension schemes: UK employer guide

Every UK employer has a legal duty to auto-enrol eligible workers into a qualifying workplace pension and to pay contributions. The choice of scheme, NEST or a commercial alternative, determines your monthly administrative load, the member experience, the investment options and the ease of moving between providers. This article is a practical comparison for UK employers and for international employers standing up UK payroll for the first time. It is framework-level, not a product review, and it assumes you already know the basics of auto-enrolment.

Auto-enrolment in one paragraph

Since 2018, every UK employer must automatically enrol eligible jobholders (aged 22 to State Pension Age, earning above the earnings trigger, working in the UK) into a qualifying workplace pension. Minimum contributions are currently 8 per cent of qualifying earnings, of which at least 3 per cent must come from the employer. The employer must handle enrolment, opt-outs, opt-ins, re-enrolment (every three years), communications, and a declaration of compliance to The Pensions Regulator every three years. Get any of this wrong and TPR can issue fixed penalty notices and escalating fines.

This is general guidance; for tailored advice on your scheme choice, contact info@octagon.nl.

What makes a pension scheme "qualifying"

A qualifying scheme must meet statutory tests set out in the Pensions Act 2008 and Pension Schemes Act 2017, and enforced by TPR and the Financial Conduct Authority. The headline requirements:

• Minimum contribution level. The scheme must be able to receive at least the 8 per cent statutory minimum on qualifying earnings, or an equivalent "set 1", "set 2" or "set 3" certification basis for defined-contribution schemes.
• Default fund. Members who do not make an active investment choice must be enrolled in a default arrangement designed for the scheme's membership. The default must follow the TPR default strategy guidance.
• Charges cap. The default fund in a DC scheme used for auto-enrolment is subject to a 0.75 per cent annual charges cap on the member's pot. Some non-default funds and pre-existing arrangements are exempt.
• Governance. Master trusts require TPR authorisation under the Master Trusts Authorisation Regime. Contract-based group personal pensions require an Independent Governance Committee under FCA rules.
• No barriers. The scheme must allow members to join and leave without penalty and must accept transfers in and out.

Any scheme that meets these tests is usable for UK auto-enrolment. The commercial question is which one to use.

NEST: government-backed, built for the job

The National Employment Savings Trust (NEST) was set up under the Pensions Act 2008 specifically to guarantee that every employer, especially the smallest, had access to a qualifying scheme. It is a not-for-profit master trust, governed by NEST Corporation as trustee, and designed to meet auto-enrolment obligations with minimum employer friction.

Key characteristics:

• Public service obligation to accept any UK employer and any eligible worker. No risk rating, no minimum headcount, no minimum contribution volume.
• No employer set-up fee and no ongoing employer admin fee. Member charges sit within the statutory cap and are funded from a combination of an annual contribution charge (currently 1.8 per cent on each contribution) and an annual management charge on the pot (currently 0.3 per cent).
• Default fund is the NEST Retirement Date Fund, a target-date glide path suited to first-time savers.
• Limited fund range beyond the default: ethical, higher-risk, lower-growth and Sharia variants, plus a pre-retirement fund. NEST is not designed for members who want active-management choice.
• Transfers in and out are permitted without restriction, which makes NEST easy to leave.
• Support channels are designed for high-volume use: employer web portal, payroll-provider integrations, and a member-facing app.

For employers whose priority is to meet the statutory duty with the smallest possible ongoing admin load, NEST is the path of least resistance. For employers whose priority is to build a high-engagement scheme for higher earners, it is often not the right choice.

Commercial alternatives at a framework level

Four commercial providers cover most of the auto-enrolment master-trust and group personal pension market for UK employers: The People's Pension, Smart Pension, Aviva, and Scottish Widows. Each has its own fee structure, fund range, and service model. The framework-level differences:

• The People's Pension. Master trust. Low-charge, broadly NEST-alternative in positioning, with a wider default-fund choice and a more flexible member experience. Strong for mid-sized employers wanting a simple, low-touch commercial alternative.
• Smart Pension. Master trust. Digital-first, API-friendly, built for payroll-provider integration. Strong for tech-enabled employers and groups standing up UK payroll as part of a wider international operation.
• Aviva Workplace Pension. Group personal pension plus master trust options. Strong investment fund range, full active and passive choice, well-regarded member communications. Strong for employers with a higher-earner population and a desire to offer real investment flexibility.
• Scottish Widows Retirement Account. Master trust and GPP. Lloyds-owned, integrated with wider workplace benefits and banking, reasonably broad fund range. Strong for employers wanting one provider across pension, protection and savings.

Outside the big four, other master trusts (including Legal and General, Aegon, Standard Life and Cushon) serve specific segments well. This article deliberately does not rank them; the right provider is specific to the workforce.

Commercial schemes typically differ from NEST on four dimensions:

1. Employer fees. Commercial schemes more often charge an employer implementation fee, an ongoing administration fee or a minimum contribution requirement. NEST does not.
2. Member charge structure. NEST's split between a contribution charge and a pot charge is unusual. Most commercial master trusts use a single annual management charge on the pot. Over long careers with steady contributions, the effective member cost can be very similar; in the first few years of saving, NEST looks more expensive because the contribution charge front-loads costs.
3. Fund range. Commercial schemes normally offer a broader range of funds, including active management options, beyond the default.
4. Service model. Commercial schemes invest in named account managers and dedicated employer support for larger clients. NEST's employer support is standardised and volume-oriented.

Cost of ownership for employers

The employer cost of running an auto-enrolment scheme is not the scheme charge (that is a member cost). The employer cost has four layers.

1. Implementation. Setting up the scheme, configuring the payroll integration, issuing initial communications, and running the first enrolment cycle. With NEST, this is usually self-service and free. With commercial providers, it may involve implementation fees between GBP 0 and low four figures depending on headcount and provider.
2. Contribution handling. Monthly. Your payroll provider calculates qualifying earnings, deducts member contributions and remits them with the employer contribution to the scheme by the statutory deadline (the 22nd of the following month for electronic payments). Modern payroll software with a provider integration makes this effectively zero-effort. Manual remittance, for example a one-off joiner mid-cycle, adds a few minutes per transaction.
3. Communications. Statutory auto-enrolment, opt-out, opt-in, re-enrolment and charges-cap disclosures. Most scheme providers generate these templates; the employer is responsible for distribution and timing.
4. Governance and compliance. The declaration of compliance every three years, the re-enrolment cycle, and any TPR inspection. Schemes with a good employer portal make this easy; schemes without, or employers without a dedicated HR lead, find this is where errors creep in.

For a small employer with under 50 UK employees, the cost of ownership of NEST and a low-fee master trust is similar, usually dominated by payroll-integration fit. For a larger employer with several hundred UK employees, the differences start to matter: integration quality, employer-portal reporting, and scheme account-management quality have real operating-cost implications.

When NEST is the right choice

NEST is typically the right choice when:

• The UK workforce is small (fewer than 50 eligible jobholders).
• The priority is compliance with the minimum employer admin load.
• Most of the workforce is at or near the statutory minimum contribution levels, and no salary sacrifice arrangement is in place.
• The employer does not want to negotiate an implementation fee or minimum contribution volume.
• The UK population is part of a wider international group where the pension offer is expected to be basic-plus, with richer benefits delivered through other vehicles.

NEST is also a common default for EOR employers, because the EOR provider can onboard new UK employees in days rather than weeks.

When a commercial scheme is the right choice

A commercial scheme is typically the right choice when:

• The UK workforce is larger (more than 100 eligible jobholders) and the employer wants dedicated account management.
• The employer wants to offer salary sacrifice on pension contributions to both employer and employees. NEST supports salary sacrifice, but many commercial schemes have more developed payroll integrations for it.
• The workforce includes higher earners who value investment fund choice and self-directed funds.
• The UK operation is part of a global mobility population and the employer wants the pension provider to sit alongside protection, savings and wider workplace benefits.
• The employer is building a UK scheme to position competitively in the local talent market, where a commercial master trust with richer communications supports the story.

In practice, many employers move from NEST to a commercial scheme as they grow past the 100-employee mark, or retain NEST for legacy populations and use a commercial scheme for new hires. Running both is legitimate; dual schemes raise admin load but not by a lot.

Scheme-switching: easier than it looks

Auto-enrolment schemes are designed to allow transfers without penalty. Moving a UK workforce from NEST to a commercial master trust, or between commercial master trusts, typically takes two to four months from decision to go-live, broken down roughly as: due diligence and provider selection (4 to 6 weeks), payroll-integration build (2 to 4 weeks), member communications and transfer window (4 to 8 weeks), and parallel-running in the first month. The compliance risk of a move is low if the sequencing is clean and the member communications are TPR-compliant. The operational risk is higher: payroll-integration errors in the first month account for most post-migration incidents.

FAQ

Is NEST automatically a qualifying scheme?

Yes. NEST was established by statute to be a qualifying scheme for auto-enrolment purposes. Its default fund complies with the charges cap and the governance framework set out by TPR and the FCA. Using NEST satisfies the employer's duty to provide a qualifying scheme.

Can an employer use more than one pension scheme?

Yes. Employers can use multiple qualifying schemes, for example NEST for the general workforce and a group personal pension for senior employees, provided each eligible jobholder is enrolled into a qualifying scheme. The admin load is higher and the communications need careful design, but it is a legitimate structure.

How does the 0.75 per cent charges cap work?

The cap applies to the default fund of a DC scheme used for auto-enrolment and limits the total annual charge borne by the member to 0.75 per cent of the pot. NEST's contribution charge does not sit inside this cap in the usual way; it is applied before the pot accumulates, and is assessed in combination with the annual management charge under TPR's guidance. Non-default funds are not subject to the cap.

What happens if the employer misses a contribution deadline?

Contributions are due by the statutory deadline, normally the 22nd of the month following payroll for electronic payments. Late or missed contributions must be reported to TPR if material and may trigger a penalty notice starting at GBP 400 for a fixed breach, rising for ongoing non-compliance. Repeated breaches can result in escalating penalties and, for severe cases, prosecution. Schemes will chase missing contributions and, if they cannot resolve the issue, escalate to TPR.

Does an EOR need its own pension scheme?

Yes. When an EOR employs your UK worker, the EOR is the legal employer and must auto-enrol the worker into its own qualifying scheme. This is usually a commercial master trust or NEST under the EOR's own master agreement. The client's own scheme is not used.

What is re-enrolment and when does it happen?

Every three years from the employer's staging or duty start date, employers must identify workers who have opted out or ceased active membership, re-enrol those who still meet the eligibility criteria, and file a re-declaration of compliance with TPR. The re-enrolment date sits within a six-month window around the three-year anniversary and the employer chooses the precise date.

Are international workers on UK payroll in scope?

If the worker is an eligible jobholder (ordinarily working in the UK, meeting the age and earnings tests), they are in scope regardless of nationality. Short-term assignments of less than three months in the UK may be excluded under specific rules, but the default position is that UK payroll equals in-scope.

What this means for UK employers

The scheme choice is not usually the biggest lever on employer cost of ownership. The bigger levers are payroll integration quality, accuracy of qualifying-earnings calculations, and the compliance discipline around re-enrolment and communications. A well-run NEST scheme outperforms a badly integrated commercial master trust on cost of ownership every time. Conversely, a growing UK workforce running on NEST with minimal integration will start to see admin load creep in around 80 to 120 eligible jobholders, and a move to a commercial scheme with good API integration becomes worth the effort.

Four practical recommendations. First, if you are setting up UK payroll for the first time and the UK population is under 50, start with NEST. You can move later. Second, if you are setting up UK payroll for 100+ from day one, run a short RFP across three or four master trusts against your payroll provider's integrations. Do not skip the payroll integration test; it determines your admin load. Third, if you are already on NEST and considering moving, sequence the switch at a natural break (fiscal year, a payroll provider change, a re-enrolment cycle) to minimise member confusion. Fourth, whoever you choose, build the re-enrolment schedule into your HR compliance calendar on day one. The three-year cycle is where most employer errors happen.
