Aipedia: Payroll bureaux
Auto-enrolment duties sit with the employer, but a bureau that runs the assessment with AI can be liable to the employer for missed enrolments. Backdated contributions and remedial costs can build up quietly across a workforce.
Part of: AI in payroll bureaux
In short
Many bureaux run auto-enrolment assessments inside payroll, sometimes with AI that categorises workers and calculates contributions. The legal duty belongs to the employer, which must enrol eligible staff aged 22 to State Pension age earning at least £10,000 a year and write to them within six weeks of becoming eligible. The Pensions Regulator deals with the employer, not the bureau. If the bureau's tool misassesses workers, the employer may claim its remedial costs. PI usually responds to that negligence claim, subject to the wording, while regulatory penalties and contributions the employer always owed are usually treated differently.
Each pay period, payroll must assess every worker by age and earnings, enrol those who qualify, deduct and pay contributions, and send the right letters. Bureaux use AI to classify workers, handle variable earnings, apply postponement, track opt-outs and re-enrolment, and reconcile contribution files with pension providers.
The risk is that assessment rules are hidden inside a tool. A worker who crosses the earnings trigger in one period, or turns 22, may be missed if the tool smooths or misreads the data. Bureaux also pass contribution files to pension providers, so an error can travel outside payroll before anyone notices.
GOV.UK's guidance on workplace pensions for employers says employers must enrol staff and make an employer's contribution if they are aged between 22 and State Pension age, earn at least £10,000 a year and normally work in the UK. If someone becomes eligible because their age or earnings change, the employer must enrol them and write to them within six weeks. The Pensions Regulator supervises employers on these duties, so the bureau's exposure is to its client rather than to the regulator.
The bureau owes the client reasonable care and skill under section 13 of the Supply of Goods and Services Act 1982. Assessment and enrolment involve personal data, so Article 28 processor terms apply, and automated decisions about whether to enrol someone may need to be considered under UK GDPR Articles 22A to 22D.
Illustrative scenario: a bureau uses an AI tool to assess a hospitality client's workforce, where hours swing from week to week. The tool averages earnings over several periods instead of assessing each one, so workers who cross the trigger in busy weeks are never enrolled. When the error comes to light, the employer must put the workers back in the position they should have been in, pays professional fees, and deals with the regulator.
Other errors include postponement letters sent to the wrong staff, opt-outs processed outside the permitted window, or contributions calculated on the wrong earnings definition. Each one is small. Across a workforce and a few years, the total can be significant.
Where the employer claims that the bureau negligently assessed workers, PI usually responds to compensation and defence costs, subject to the policy terms. Contributions the employer always owed are not normally the bureau's loss. The employer's extra administrative costs, the cost of correcting records with the pension provider, and advisers' fees are the parts more likely to fall within a negligence claim. Regulatory penalties imposed on the employer are usually excluded or uninsurable. See fines and penalties under PI.
Because one assessment rule applies to everyone, aggregation can matter. See gross-to-net errors for how multi-employee claims are often treated, and does payroll PI cover AI mistakes for how wordings approach tool-driven errors.

Apex arranges professional indemnity for payroll bureaux. A broker can check how your wording treats claims for remedial pension costs and whether your limit reflects the workforces you assess. More in AI in payroll bureaux.
The employer holds the legal duty and deals with The Pensions Regulator. A bureau that runs the assessment owes the employer a contractual duty of reasonable care and skill, so it can be liable to the employer if its process misassesses workers.
GOV.UK guidance says staff aged between 22 and State Pension age, earning at least £10,000 a year and normally working in the UK. Someone who becomes eligible because of a change in age or earnings must be enrolled and written to within six weeks.
Usually not the contributions the employer always owed, which are its own liability. The employer's extra administrative costs, the cost of correcting records and professional fees may be claimed against the bureau and may be covered, subject to the policy terms.
It is sensible to describe how assessments are run when completing a proposal form or at renewal. Insurers ask about the services provided and the controls in place, and a clear description helps avoid later arguments about what was disclosed and what the policy was meant to cover.
