Thirty-six Northern Ireland employers were named this week for underpaying staff. Twenty of them owed under £100 a head.

Reacting to: NI employers named for not paying staff minimum wage (BBC News NI, 3 September 2026) →

The Department for Business and Trade published its latest minimum wage naming round this morning: nearly 660 employers across the UK, £4m returned to more than 27,000 workers, £7m of penalties. The national coverage has gone to B&Q and Five Guys, and we have written up the mechanisms that caught them separately. This is the Northern Ireland cut, because the local list has a different shape and a different set of consequences attached to it.

Thirty-six of the named businesses are here — a care provider, hotels, solicitors, nurseries, filling stations, butchers, a golf club and a cleaning co-operative, spread from Belfast to Castlederg. Add the Northern Ireland entries up and they come to £147,393 owed to 1,241 workers, an average of £118.77 a person. That is the wrong shape for a story about employers choosing to underpay, and it is worth saying so before anyone reaches for "named and shamed".

Twenty of the thirty-six owed under £100 a head

Sort the local list by arrears per worker rather than by total and it stops looking like a rogues' gallery. Twenty of the thirty-six averaged under £100 a worker. Nine averaged under £50. The business at the top of that ranking owed £23.78 each to 138 people. Nobody sets out to underpay 138 staff by twenty-four pounds — that is a payroll setting, running quietly, for a while.

So four in five of the workers on the Northern Ireland list were owed less than £100. The severity is not in the individual error. It is in the multiplier and in what the state does about it afterwards.

The number that decides whether you appear is £500

An employer is only eligible for naming if the total value of arrears owed across all its workers exceeds £500. Not £500 each — £500 across the whole payroll, across however long the underpayment ran. The smallest Northern Ireland entry in this round was £529.51 owed to two people. Twenty-nine pounds and fifty-one pence over the line.

Against April 2026 rates that bar is easy to clear. The rate for workers aged 21 and over rose 50p to £12.71, the 18 to 20 rate rose 85p to £10.85, and under 18s and apprentices sit at £8.00. At £12.71, one minute of unpaid time costs 21.2p.

What £2,722 of arrears actually costs, three ways

An illustration built from the published rules rather than a client file. Take a 38-person hospitality and retail business paying weekly, most of the team on £12.71. Over thirteen weeks it manages an £18 uniform deduction from 22 new starters (£396), six unpaid handover minutes a shift for 20 people (£1,321.84), and two staff who turned 21 and stayed on the 18 to 20 rate for nine weeks (£1,004.40). Total arrears £2,722.24 across 34 people — £80.07 a head, right in the middle of the Northern Ireland pattern.

The penalty on a notice of underpayment is 200% of the total underpayment, with a floor of £100 per notice and a ceiling of £20,000 per worker. It halves to 100% if the arrears and the penalty are paid within fourteen days of service. But there is a third column most people never see, because it only exists before HMRC opens a case.

The gap between the first row and the last is £5,444 and a permanent entry on a government list — for identical underpayments, identically repaid. Other than in exceptional cases there is no naming and no penalty on arrears you declare to HMRC and repay yourself. The Fair Work Agency's own enforcement statement says the same: where a business self-corrects before an investigation begins, it will not pursue enforcement on what has been voluntarily disclosed and satisfactorily corrected. That door closes the moment a case opens.

Reserved rates, devolved everything else

Two forces pull in opposite directions here, and getting them the wrong way round is how Northern Ireland employers end up badly advised.

The minimum wage is reserved. Stormont has never set the rates and cannot. A Newry employer faces exactly the rates, the penalty regime and the naming rounds a Manchester employer does, and the Fair Work Agency's enforcement statement confirms it operates across England, Wales, Scotland and Northern Ireland, subject to the jurisdictional arrangements in each nation. HMRC does the minimum wage work on its behalf. Nothing about being here softens any of it.

Everything around the minimum wage is devolved and different. Holiday pay and working time sit with the Assembly, so the Agency widening into those areas in Great Britain does not by itself reach Northern Ireland. More immediately, the route a worker takes is not the Great Britain route. Claims here go to an industrial tribunal, not an employment tribunal. Since 27 January 2020 a claimant must first notify the Labour Relations Agency and consider Early Conciliation before a claim can proceed at all, and the LRA issues a certificate whose number the tribunal requires. Early Conciliation runs for up to a calendar month, extendable by a fortnight. A claim for unpaid wages needs no minimum service, so someone three weeks into a job can bring one.

This is where a lot of generic advice fails. Guidance written for Great Britain tells an employer who finds a problem to ring ACAS first. ACAS has no remit in Northern Ireland. The equivalent here is the LRA's Workplace Information Service on 03300 555 300, and it is free. If your staff handbook, your HR platform or your template contracts name ACAS or an employment tribunal, they were written for somewhere else — the ground the Northern Ireland employment law guide covers.

Three things worth doing this week

Run the arithmetic on your lowest-paid person, not your average. Take one pay period. Take their gross pay, subtract every deduction and every unreimbursed cost they carried for the job, and divide by every minute they were required to be there. If the answer starts with 12.7 you are fine. If it does not, you have found it before anyone else has.

List every deduction running through your payroll and ask what each one is for. Uniform, tools, training, till shortages, salary sacrifice, parking. Anything connected with the job reduces minimum wage pay. Twenty minutes of work and the highest-yield check on this list.

If you find arrears, declare them before anyone opens a case. HMRC runs a voluntary declaration process for employers who identify and repay arrears themselves — that is the £2,722 column rather than the £8,167 one. Request the form by emailing voluntarydeclaration.nmw@hmrc.gov.uk, and HMRC's employer factsheets set out the self-review method to use first.

What is still open

Two things are unsettled. The Fair Work Agency's expansion into holiday pay and statutory sick pay enforcement has been legislated for but is not in force, and how much of it lands here turns on the reserved and devolved split rather than on the Agency's intentions. No commencement date has been published for either. And there is no fixed calendar for naming rounds, so a business currently under investigation has no date by which it will know its position — the Department has published these lists at irregular intervals for years and said nothing this morning about when the next one falls.

What is settled is the arithmetic. £500 of total arrears puts you on the list, the penalty is double the arrears unless you clear everything inside fourteen days, and declaring it yourself first costs neither. If you would rather have your payroll checked than discovered, that is what our payroll team does, and what our Northern Ireland office in Ballymena is here for.
