While the legal duties have not fundamentally changed in 2026, updated HSE guidance and the introduction of the amended BS 8599-1:2019+A1:2026 British Standard for workplace first aid kits are prompting many organisations to reassess whether their first aid provision remains suitable for today's workplace.

First aid provision must be "adequate and appropriate"

Under UK law, every employer has a duty to provide adequate and appropriate first aid equipment, facilities and personnel for their workplace. The level of provision required depends on a workplace-specific first aid needs assessment rather than a fixed legal requirement.

Employers should consider a range of factors when carrying out their assessment, including:

• The nature of the work being undertaken.
• Workplace hazards and associated risks.
• The number of employees and visitors.
• Shift patterns and lone working arrangements.
• Employees working remotely or off-site.
• Previous accident history.
• The availability and response time of local emergency services.

The HSE recommends reviewing the assessment whenever workplace activities, staffing levels or risks change.

Reviewing first aid kits in line with current standards

One of the most significant developments during 2026 is the publication of the amended BS 8599-1 standard for workplace first aid kits.

Although compliance with the British Standard is not a legal requirement, many employers use it as a benchmark when selecting or updating their first aid supplies. The revised standard places greater emphasis on matching first aid equipment to the specific risks identified within the workplace rather than relying on a generic kit for every environment.

Higher-risk industries such as manufacturing, engineering, warehousing and construction may require additional items beyond a standard workplace first aid kit to reflect the injuries most likely to occur.

Choosing the right level of first aid training

The HSE does not specify exactly how many trained first aiders every business must have. Instead, employers are expected to determine appropriate staffing through their first aid needs assessment.

In lower-risk workplaces, such as small offices or retail premises, a suitably stocked first aid kit and an appointed person may be sufficient. However, organisations with higher-risk activities or larger workforces are likely to require trained Emergency First Aid at Work (EFAW) or First Aid at Work (FAW) personnel.

Employers are also responsible for ensuring first aid certificates remain valid and that adequate cover is available during holidays, sickness and shift changes.

Mental health remains part of the conversation

Since amendments to HSE guidance in 2024, employers have been encouraged to consider employees' mental health and wellbeing when carrying out their first aid needs assessment.

Although Mental Health First Aid training is not a legal requirement, many organisations are incorporating wellbeing support into their wider health and safety strategies as part of a proactive approach to workforce welfare.

Heat safety becoming a growing workplace issue

The recent periods of extreme summer temperatures have also increased attention on workplace safety. While the UK currently has no legal maximum workplace temperature, employers still have a duty under health and safety law to assess heat-related risks and take reasonable steps to protect workers.

The government has confirmed that the HSE intends to consult on workplace heat safety, following growing calls from trade unions, campaigners and politicians for clearer guidance on managing high temperatures at work.

Practical steps employers can take

To remain compliant with current HSE expectations, employers should regularly:

• Review and document their first aid needs assessment.
• Ensure first aid kits are suitable for workplace risks and checked routinely.
• Confirm that trained first aiders hold current qualifications.
• Inform employees about first aid arrangements and emergency procedures.
• Reassess first aid provision whenever staffing levels, premises or workplace risks change.

Looking ahead

Workplace first aid continues to evolve alongside changing working practices, updated clinical guidance and new British Standards. Although the legal framework remains centred on providing "adequate and appropriate" first aid arrangements, employers who regularly review their procedures, equipment and training are better placed to protect both their workforce and their business.

With increased attention on risk-based first aid provision, mental wellbeing and heat-related safety, 2026 is shaping up to be an important year for organisations committed to maintaining high standards of workplace health and safety.
