First Aid Requirements in the Workplace UK (2026)
Last updated: 15 October 2026
First aid requirements in the workplace UK stem from the Health and Safety (First-Aid) Regulations 1981, which obliges every employer to provide adequate first aid equipment, facilities and trained personnel. There is no fixed ratio of first aiders to staff; instead, employers must complete a needs assessment, and certificates for First Aid at Work (FAW) and Emergency First Aid at Work (EFAW) last three years.
Key Takeaways
- Priority First notes that the Health and Safety (First-Aid) Regulations 1981 require every employer in Great Britain to provide adequate first aid equipment, facilities and trained personnel without specifying fixed staff-to-first-aider ratios.
- 680,000 workers sustained a non-fatal workplace injury according to self-reports from the Labour Force Survey in 2026/25, per HSE – Non-fatal injuries at work in Great Britain.
- Employers reported 59,219 employee non-fatal injuries under RIDDOR (the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) in 2026/25, per HSE.
- Emergency First Aid at Work (EFAW) certificates require a minimum of six hours' training, while First Aid at Work (FAW) certificates require at least 18 hours over three days, and both last three years before requalification, per High Speed Training and HSE.
- Slips, trips and falls on the same level caused 30% of RIDDOR-reported non-fatal injuries in 2026/25, making them the single largest cause employers must plan first aid cover around, per HSE.
Priority First Explains What the Health and Safety (First-Aid) Regulations 1981 Require Employers to Provide
The Health and Safety (First-Aid) Regulations 1981 is the primary UK legislation that obliges employers to provide first aid cover proportionate to the risks present in their workplace. The regulation sits alongside the Health and Safety at Work etc. Act 1974, the parent statute under which the Health and Safety Executive (HSE) enforces workplace safety across Great Britain.
Under the 1981 Regulations, as set out by HSE's legislation page, an employer must provide "such equipment and facilities as are adequate and appropriate in the circumstances for enabling first aid to be rendered to his employees if they are injured or become ill at work." That duty covers three practical elements: suitably stocked first aid containers, sufficient numbers of trained personnel, and information for employees on arrangements in place.
The scale of the risk this legislation addresses is substantial. HSE recorded 124 work-related deaths in 2026/25, according to the HSE / Access Industry Forum summary of annual statistics, and non-fatal injuries cost 4.4 million working days in the same year, per HSE data cited via Croner. The 1981 Regulations exist precisely to ensure that when incidents like these occur, competent help is already on site.
HSE's own guidance also makes clear that an "appointed person" — someone who takes charge of first aid arrangements, calls emergency services and looks after equipment, but who is not a trained first-aider — can satisfy minimum legal requirements in genuinely low-risk workplaces. Larger or higher-risk sites, however, need qualified first-aiders rather than appointed persons alone.
Who Is Responsible for Assessing First Aid Needs in a Workplace?
The employer carries legal responsibility for assessing first aid needs, and that duty cannot be delegated away even where day-to-day building management is outsourced. The assessment must consider workplace hazards, employee numbers, site layout and the nature of the work being carried out.
For a London office occupying a single floor, the employer or a nominated health and safety manager typically completes this assessment directly. For a multi-tenant commercial building or a mixed-use development, responsibility often becomes blurred between landlord, managing agent and occupying businesses — which is precisely where compliance starts to slip.
Mo Hassan, Managing Director of Priority First, has observed this pattern across compliance generally: "Compliance fails quietly. Certificates lapse, checks get missed in handovers between contractors, and everything looks fine until an incident or a sale forces an audit. The fix is unglamorous: one owner for the whole compliance calendar, evidence filed as work is done, and no assumption that the previous contractor left things in order." The same discipline applies directly to first aid provision — someone named, accountable and documented has to own it.
Priority First's facilities management service builds first aid review into the same compliance calendar as fire safety checks, legionella testing and electrical certification, so the responsibility sits with one accountable party rather than drifting between contractors.
How Do You Carry Out a First Aid Needs Assessment for Your Business?
Priority First describes a first aid needs assessment as the structured review every employer must complete under the 1981 Regulations to determine how much first aid provision a workplace genuinely requires. It should examine the specific hazards, workforce size, shift patterns and site geography of the business being assessed, rather than relying on a generic template.
HSE's own simplified first aid guidance recommends working through a short list of factors systematically:
- Workplace hazards and risks — identify specific dangers such as machinery, chemicals, working at height or lone working.
- Workforce size and composition — account for employees, agency staff, contractors and visitors on site at any time.
- Accident and ill-health history — review the accident book for patterns such as repeated manual handling injuries.
- Site layout and travel time — consider distance to the nearest NHS accident and emergency department and whether the site spans multiple buildings or floors.
- Shift patterns and lone working — ensure cover exists outside standard 9-to-5 hours, including nights and weekends.
- Remote or travelling staff — plan for employees who work away from a fixed first aid point.
Given that 10% of RIDDOR-reported non-fatal injuries in 2026/25 were acts of violence and a further 8% were falls from height, per HSE, the needs assessment should map provision against the actual injury profile of the sector, not a generic office template. A retail concierge desk in Mayfair faces a very different risk profile to a construction site in the West Midlands, and the assessment should reflect that.
How Many First Aiders or Appointed Persons Are Required Based on Employee Numbers?
UK law sets no statutory ratio of first aiders to employees, which surprises many business owners expecting a fixed formula. Instead, HSE guidance states that even in low-hazard environments, "where 25 or more people are employed… at least one such person should be provided," according to HSE guidance cited by iHASCO.
Below that threshold, an appointed person can often be sufficient, provided the needs assessment supports that conclusion. The commonly cited industry benchmarks below are widely used planning guides rather than statutory minimums — always confirmed against your own needs assessment.
| Workplace risk level | Typical employee numbers | Suggested minimum provision |
|---|---|---|
| Low risk (e.g. office, retail) | Fewer than 25 | At least one appointed person |
| Low risk (e.g. office, retail) | 25–50 | At least one EFAW-trained first-aider |
| Low risk (e.g. office, retail) | 50+ | One additional first-aider per further 100 employees (approx.) |
| Higher risk (e.g. construction, manufacturing, warehousing) | Fewer than 5 | At least one appointed person |
| Higher risk (e.g. construction, manufacturing, warehousing) | 5–50 | At least one FAW-trained first-aider |
| Higher risk (e.g. construction, manufacturing, warehousing) | 50+ | One additional first-aider per further 50 employees (approx.) |
These figures are planning benchmarks drawn from widely used HSE-aligned guidance, not fixed legal minimums — the needs assessment remains the governing document. A 152-checkpoint mixed-use site in West London with retail, residential and plant rooms running simultaneously, for instance, needs first aid provision mapped against every occupied zone and shift, not just head office hours.
What Training Must a Workplace First Aider Hold, and How Long Is It Valid?
A qualified workplace first-aider in the UK typically holds either an Emergency First Aid at Work (EFAW) certificate or a First Aid at Work (FAW) certificate, both delivered by HSE-approved training providers. EFAW courses must run for a minimum of six hours over at least one day, while FAW courses require a minimum of 18 hours spread across at least three days, according to High Speed Training.
EFAW is generally appropriate for lower-risk workplaces or as a baseline qualification, covering emergency procedures such as CPR, choking and managing an unresponsive casualty. FAW adds more comprehensive content, including fractures, spinal injuries and illness management, and is the recommended standard for higher-risk environments such as construction or manufacturing.
Both certificates last for three years, after which a requalification course is required to keep the certificate valid, per HSE's "Are you a first-aider?" guidance. HSE recommends refresher training partway through that three-year cycle to keep skills current, even though it is not a strict legal requirement for certificate validity.
Employers should also note that since 2026, HSE's L74 guidance has encouraged needs assessments to consider mental health alongside physical first aid, meaning some workplaces now add Mental Health First Aid training on top of statutory EFAW or FAW provision as a matter of good practice rather than legal obligation.
What Must Be Included in a Workplace First Aid Kit?
A workplace first aid kit is a stocked container of dressings, bandages and basic treatment items sized to match the hazards and headcount of the site it serves. There is no single mandated list under the 1981 Regulations, but the British Standard BS 8599-1:2019+A1:2026 sets out recommended kit contents scaled by workplace size and provides guidance on automated external defibrillator (AED) provision.
BS 8599 typically scales kits from small (fewer than 25 employees) through to large (more than 100 employees), with contents including sterile dressings, triangular bandages, eye pads, adhesive plasters and disposable gloves. Industry-specific additions are common: construction sites often add eyewash stations and burns dressings given the prevalence of foreign-body and chemical exposure risks, while kitchens and hospitality venues typically include burns gel.
Automated external defibrillators are not a statutory requirement under the 1981 Regulations, but BS 8599's updated guidance recommends considering AED provision for sites with five or more occupants, reflecting growing awareness of sudden cardiac arrest response times. Given that falls from height accounted for 8% and struck-by-moving-object incidents accounted for 10% of RIDDOR-reported non-fatal injuries in 2026/25, per HSE, kit contents on higher-risk sites should be weighted towards trauma rather than minor ailments.
Are First Aid Requirements Different for High-Risk Workplaces Versus Low-Risk Offices?
High-risk workplaces such as construction sites and manufacturing plants face materially higher first aid obligations than low-risk offices, driven by the likelihood and severity of injury rather than headcount alone. A construction site handling heavy plant, working at height and manual handling typically needs FAW-trained first-aiders rather than EFAW, reflecting the broader range of serious injuries those environments produce.
Low-risk offices, by contrast, can often rely on EFAW-trained staff or even an appointed person alone, provided the needs assessment genuinely supports that lower provision. The distinction matters in practice: slips, trips and falls on the same level caused 30% of RIDDOR-reported non-fatal injuries in 2026/25, per HSE, which affects offices and warehouses alike, while handling, lifting and carrying injuries (17%) skew far more heavily towards warehousing, logistics and construction settings.
In practice, Priority First's work across 24 sites on a single client portfolio — spanning prime residential blocks, mixed-use developments and construction-adjacent properties — shows how provision has to flex by site type even within one managing structure. A 96-unit care home in Bedfordshire, for example, needed round-the-clock documented coverage precisely because care staff could not simultaneously deliver resident care and dedicated incident response; Priority First deployed SIA-licensed officers whose patrols, incidents and handovers were logged with photograph, GPS and timestamp on every checkpoint, giving the operator provable cover rather than an assumed one. The same logic that drove that security deployment — documented, auditable, site-specific coverage — applies directly to how first aid provision should be planned and evidenced.
What Records Must Employers Keep for First Aid Compliance?
Employers must maintain an accident book recording every workplace injury treated, alongside valid training certificates for every qualified first-aider and appointed person on site. The accident book, commonly the HSE-endorsed BI 510 format, should log the date, time, nature of injury and treatment given, and it forms the primary evidence base if HSE or an insurer later queries an incident.
Training certificate records should show the qualification type (EFAW or FAW), the issuing provider, the award date and the three-year expiry date, so renewals are never missed. Employers reporting injuries meeting RIDDOR thresholds — over-seven-day incapacitation, specified injuries or certain occupational diseases — must also submit a report to HSE via the RIDDOR online system, separate from internal accident book entries.
For multi-site operators, consolidated record-keeping across every location is where compliance commonly breaks down, particularly when contractor handovers happen without a clean paper trail. Priority First's building audit and risk assessment work routinely surfaces exactly this gap: certificates that expired months earlier, accident books held at the wrong site, or first aid provision that was never reassessed after a change of use.
Your First Aid Requirements Checklist
- Complete a documented first aid needs assessment covering hazards, headcount, shift patterns and site layout.
- Confirm whether an appointed person or a qualified EFAW/FAW first-aider is legally sufficient for your risk profile.
- Book FAW training (minimum 18 hours over three days) for higher-risk sites, or EFAW (minimum six hours) for lower-risk sites.
- Diarise certificate renewal three years from the award date to avoid lapses.
- Stock first aid kits to BS 8599-1 standards and review contents against your sector's injury profile.
- Maintain an up-to-date accident book and file RIDDOR reports for qualifying incidents.
- Extend first aid provision explicitly to remote workers, lone workers and every site in a multi-site estate.
- Assign one named, accountable owner for first aid compliance across the whole organisation.
FAQ
What does UK law require employers to provide for first aid?
The Health and Safety (First-Aid) Regulations 1981 requires employers to provide adequate first aid equipment, facilities and trained personnel proportionate to workplace risk. This includes a stocked first aid kit, access to an appointed person or qualified first-aider, and information for employees on arrangements in place, per HSE.
How many first aiders do I need for a small office?
There is no fixed legal ratio, but HSE guidance suggests at least one first-aider or appointed person once staff numbers reach 25 in a low-risk environment. Below that figure, an appointed person is often sufficient provided a documented needs assessment supports that decision.
What is the difference between EFAW and FAW training?
Emergency First Aid at Work (EFAW) requires a minimum of six hours' training and covers emergency essentials like CPR and choking. First Aid at Work (FAW) requires a minimum of 18 hours over three days and covers a wider range of injuries and illnesses, making it the recommended standard for higher-risk workplaces, per High Speed Training.
How long does a first aid certificate last?
First aid certificates for both FAW and EFAW remain valid for three years from the date of issue. After three years, the first-aider must complete a requalification course to continue holding the certificate, per HSE.
Do remote or lone workers need separate first aid provision?
Yes, employers must extend first aid cover to remote workers and lone workers as part of their needs assessment, even though provision looks different from a fixed office. Typical measures include providing a personal first aid kit, ensuring access to a mobile phone for emergency contact, and establishing check-in procedures for lone workers on isolated sites.
Are defibrillators (AEDs) a legal requirement in UK workplaces?
No, AEDs are not a statutory requirement under the 1981 Regulations. The British Standard BS 8599-1:2019+A1:2026 recommends considering AED provision where five or more people regularly occupy a site, but this remains guidance rather than law.
What happens if an employer fails to meet first aid requirements?
Non-compliance with the 1981 Regulations can lead to HSE enforcement action, including improvement notices, prohibition notices or prosecution under the Health and Safety at Work etc. Act 1974 in serious cases. Given that non-fatal workplace injuries cost 4.4 million working days in 2026/25, per HSE data cited via Croner, inadequate first aid provision also carries significant operational and reputational risk beyond the legal exposure.
Keeping first aid compliance provable, not assumed
First aid provision is only one strand of the compliance calendar that building owners and employers must manage alongside fire safety, electrical certification and security — and Priority First sees the same failure pattern across all of them: responsibility assumed rather than confirmed. Priority First's facilities management service brings first aid needs assessments, certificate tracking and accident book review into the same documented compliance framework used across its managed sites.
Across Priority First's portfolio, evidence standards matter as much as the provision itself — every security checkpoint on a managed site requires a photograph, GPS location and timestamp to complete, so coverage is demonstrable rather than asserted, and the same discipline applies to how compliance records should be maintained. If your business needs a structured first aid needs assessment folded into a wider facilities and compliance review, get in touch with Priority First for a consultation.
