UK businesses are facing a fresh "onerous responsibility" over holiday entitlement and pay compliance, following the Government's April 6 launch of the Fair Work Agency (FWA) alongside updated regulations, according to business specialists.
The latest annual business activity data from the Office for National Statistics shows there are 2.73 million VAT and/or PAYE registered businesses across the UK, suggesting substantial numbers of firms could face implications.
Six-year record-keeping requirement
Employers must now retain holiday entitlement and pay documentation for six years, mirroring National Minimum Wage record-keeping requirements. Documentation must detail annual entitlements, dates when leave is utilised and employee payments for each period of leave, including any pay in lieu of holiday upon employment termination.
While the concept appears straightforward, the practical implementation proves considerably more intricate, according to Hannah-Jane (H-J) Dobbie, head of HR consultancy at Azets, a UK top 10 accountancy and business advisory firm.
HR and payroll must work together
She explained: "Typically, HR will deal with holiday entitlement calculations and payroll will deal with holiday pay. But with the new onerous responsibility requiring all the data to be in one place and easily accessible, it means HR and payroll will need to work more closely together than ever before."
Holiday entitlement for workers with variable hours and variable pay can be calculated using the 'percentage method', while holiday for those with fixed hours and fixed pay is relatively straightforward, H-J explained. However, she cautioned that this is far from the case for workers with fixed hours but variable pay.
She added: "For example, if they regularly work overtime, receive allowances or commission or are paid shift premiums. The calculation for these workers, based on the 'calendar method', is so complicated that employers often don't know where to start.
"What has come to light is that employers do not understand the calendar method or how to calculate holiday pay correctly. We are identifying underpayments where workers have not had variable pay components, such as regular overtime, shift premiums, etcetera, included in their holiday calculations."
Employers in a state of panic
Employers are in a state of panic as they don't know how much will be owed to employees when the extent of the underpayments is known, especially as they may have to go back as far as two years to make good with their workers. What's more, they are terrified that the new Fair Work Agency (FWA) will impose hefty fines or open criminal investigations for worker exploitation even though they are trying to do right by staff.
"I'm getting calls from bosses of well-run companies worried sick about falling foul of compliance through no fault of their own; they want to ensure staff are paid what they are owed, but the calculation method is so difficult for what appears to be the largest group of workers, that it leaves them exposed, and as of now, we haven't found two employers tackling this in the same way," H-J said.
"Bear in mind that holiday pay has to be calculated each time a worker takes leave, so this is not just a one-off annual calculation, rather it has to be carried out multiple times per worker, per year. It wouldn't be an overstatement to say that thousands of businesses, particularly smaller ones without experienced HR and payroll teams, are struggling with the concept of the paperwork that is required to comply."
While the majority of employees receive monthly salaries, the calculation must be performed on a weekly basis. H-J noted that practical guidance on navigating this process remains virtually non-existent, with no employer yet identifying a relevant example within the government's official documentation.
She added: "Incredibly, there is no payroll or HR system capable of handling this holiday pay scenario, based on the so-called 52-week calendar method, which is why this particular rule is causing employers such a headache. It is also daft calling it the 52-week calendar method, as employers may have to go back up to 104 weeks to count sufficient weeks."
The regulations are primarily designed to safeguard employees on fixed hours who receive variable pay elements, such as overtime, bonuses, commission and allowances, as well as holiday paid in lieu upon termination of employment.
"Few businesses are getting their heads around this 52-week calendar method," H-J said. "They're coming up with all sorts of weird and wonderful ways to calculate what they think the differences are, but the sums don't add up."
H-J warned: "Getting holiday pay calculations wrong not only invites an investigation by the FWA, but opens the door to a costly employment tribunal and compensation pay-outs. Asking someone to forgo holiday entitlement to cover for other colleagues, due to staff shortages, will only end in financial tears."
FWA enforcement powers and R-Day
Launched in April, the FWA carries enforcement powers to examine premises, request records and levy unlimited fines or criminal penalties for those failing to comply. Government findings revealed the true extent of the problem: 900,000 UK workers annually have holiday pay withheld, worth £2.1 billion, with nearly 20% of minimum wage workers receiving insufficient payment.
From April 6, marking the beginning of the new tax year and referred to as R-Day (Records Day), all employers must centrally maintain precise records of holiday entitlement, holiday pay calculations and annual leave processed through payroll for a period of six years. Robust systems must be put in place to ensure records are securely stored and readily available to authorised personnel, whether held digitally or in physical form.
Earlier this year, Azets drew attention to the potential pitfalls surrounding R-Day. "Many businesses haven't seen this coming and are not prepared – it's been like a bolt out of the blue," warned Julie Gunnell, associate director for growth payroll at Azets, cautioning at the time.
"R-Day is a wake-up call. Employers need clear protocols for record access and ownership. If the FWA comes knocking and records are fragmented across HR and payroll, it becomes an admin emergency."
Julie went on to say: "This legislation is a game-changer - it ensures HR and payroll teams work collaboratively, rather than maintaining separate records, to create a single source of truth. Without this alignment, businesses risk compliance failures and potential criminal prosecution for worker exploitation."
In a recent employment tribunal ruling, a long-serving former employee was awarded £391,942.77, before tax and National Insurance, because his employer failed to pay the claimant's holiday entitlement which amounted to 827.25 days.
A Fair Work Agency spokesperson said: "The Fair Work Agency combines prevention, intelligence, support and enforcement to tackle labour market harms. By identifying risks early and improving compliance, we aim to prevent problems before they arise while taking firm action where necessary.
"Most employers want to comply with the law and we will provide guidance and support to help them do so. However, where workers are deliberately exploited or employers repeatedly fail to meet their obligations, we will take robust enforcement action.
"Holiday pay can be complex in some circumstances, particularly where individuals work irregular hours, work for part of the year, or where pay varies. Subject to implementation decisions and consultation outcomes, holiday pay enforcement is expected to begin in 2027. We will take a compliance-first approach, supported by clear guidance for employers before enforcement starts.
"We can impose financial penalties on employers who fail to pay Employment Tribunal awards or ACAS settlement agreements. Penalties are not automatic and apply where employers fail to pay within 42 days of a judgment or breach the terms of a COT3 agreement.
"Our enforcement powers complement existing routes of redress by providing a more accessible and proactive approach to tackling non-compliance. We encourage businesses to review pay, working time, deductions, agency worker arrangements and record keeping, and to address any issues before they escalate."
