Key takeaways
  • As the employer in the premises you are the responsible person for fire safety in your demise, including the fire risk assessment.
  • The electrical installation and gas appliances in your demise are yours to maintain, evidenced by an EICR and a gas safety record.
  • Portable equipment and the water outlets you control are yours too: PAT testing and a legionella assessment for the systems within the demise.
  • Your landlord keeps the structure, common parts and shared plant. Ask for their certificates and give them yours.

Taking a commercial lease moves more than the rent onto your desk. The moment your staff are working in the unit you are the employer in it, and the fire, electrical, gas and water safety law is written around the employer. The landlord owns the building; you control the space. Control is what the law follows. This guide sets out what is yours, what stays with the landlord and how to be sure.

Fire safety: you are the responsible person

Under the Fire Safety Order the responsible person for a workplace is the employer. That is you, for the space you occupy. You need a recorded fire risk assessment for your demise, extinguishers serviced annually, any alarm and emergency lighting within your space maintained, escape routes kept clear and staff trained. The landlord covers the common parts and should give you the information you need about the building's fire strategy. Start with the fire risk assessment.

Electrical: the installation and the appliances

Regulation 4 of the Electricity at Work Regulations puts the duty to maintain electrical systems on the employer. In practice the fixed wiring in your demise, from your distribution board onwards, is yours to inspect, typically every five years with an EICR. Everything you plug in is covered by the same duty and handled through PAT testing at risk-based intervals. If the landlord supplied the installation, ask for the last EICR at the start of the term and keep it.

Gas: appliances in your space

If there is a boiler, water heater or catering equipment in your demise, regulation 35 of the Gas Safety Regulations makes you, as employer, responsible for keeping it safe. An annual inspection by a Gas Safe registered engineer with commercial categories, recorded on a CP17 or CP42, is the recognised standard. Central plant that serves the whole building usually stays with the landlord. See commercial gas safety.

Water: legionella in your demise

The legionella duty follows control of the water system. If your unit has its own hot water, showers or little-used outlets, the risk assessment for those is yours. The landlord covers shared tanks, calorifiers and risers. In a small office with a single kitchen and toilets the assessment is short, but it has to exist. See legionella risk assessment.

Asbestos: your fit-out, their fabric

In a pre-2000 building the duty to manage asbestos sits with whoever has the maintenance obligation. Under most leases that means the landlord for the structure and you for your fit-out and any alterations you make. Before any works in your demise, ask the landlord for the asbestos register, and commission a refurbishment survey of the areas you will disturb. See asbestos surveys.

The general duty and the paperwork

Behind the specific duties sits the employer's general duty under the Health and Safety at Work Act to assess and manage risks to staff and visitors, which HSE expects to be recorded for any business with five or more employees. Keep every certificate and report together, give the landlord copies of what they ask for, and get copies of theirs. At lease end those records also feed the dilapidations conversation, because a well-maintained unit is easier to hand back.

Frequently asked questions

What compliance is a commercial tenant responsible for?+
As the employer in the premises: the fire risk assessment and fire equipment in the demise, the electrical installation and portable appliances, any gas appliances in the space, the legionella assessment for water systems it controls, and asbestos management for its own fit-out. The landlord keeps the structure, common parts and shared plant.
Is the tenant or the landlord responsible for the fire risk assessment?+
Both, for different parts. The tenant, as employer, is the responsible person for the space it occupies. The landlord is the responsible person for common parts and the structure. They must cooperate and share information.
Does a commercial tenant need an EICR?+
Yes, for the fixed installation in its demise. The Electricity at Work Regulations place the duty to maintain electrical systems on the employer, and a periodic inspection is how it is evidenced. Ask the landlord for the last report at the start of the lease.
Does a commercial tenant need a legionella risk assessment?+
Yes, for any water system it controls within the demise. Shared systems such as tanks and risers are usually the landlord’s. For a small office the assessment is proportionate and inexpensive.
