Who is the "Responsible Person" in a Commercial Lease?

You have finally signed the lease on your new commercial premises. The ink is dry, the fit-out is complete, and suddenly, the local fire authority or an insurance inspector asks to see your Fire Risk Assessment. Your immediate thought? "Surely that’s the landlord's job?"

Unfortunately, assuming your landlord handles all building compliance is one of the most common—and financially devastating—mistakes made by commercial tenants in the UK. Under UK fire safety law, accountability does not automatically default to the person who owns the bricks and mortar.

To avoid massive fines, invalidated insurance, and potential prosecution, you must understand exactly who the law defines as the "Responsible Person" in a commercial lease setup.

The Law: The Regulatory Reform (Fire Safety) Order 2005

In the UK, commercial fire safety is governed by the Regulatory Reform (Fire Safety) Order 2005 (often referred to as the FSO). This legislation shifted the burden of fire safety away from the fire brigade issuing certificates, and placed it squarely on the shoulders of the "Responsible Person."

Article 3 of the FSO defines the Responsible Person in a workplace as the employer. If you run a business from the premises and employ staff, you are automatically the Responsible Person for the area under your control. If the premises is not a workplace, the Responsible Person is the person who has control of the premises (usually the tenant holding the lease).

The Multi-Tenant Trap: Where Lines Blur

The situation becomes highly complex in multi-tenanted commercial buildings, such as large office blocks or shopping centres. In these scenarios, there is rarely just one Responsible Person.

Generally, the division of responsibility works like this:

• The Landlord / Managing Agent: Is responsible for the communal areas. This includes shared stairwells, lobbies, communal fire alarms, and shared escape routes. Property managers handling block management will usually arrange the communal risk assessments.
• The Commercial Tenant: Is responsible for everything inside their leased unit. This includes their own emergency lighting, internal fire doors, staff training, and a dedicated FRA for their specific business operations.

However, under Article 22 of the FSO, there is a strict legal requirement for Co-operation and Co-ordination. If your internal fire door fails, it compromises the landlord's communal escape route. Therefore, landlords will frequently demand to see a copy of your FRA to ensure your negligence doesn't put the wider building at risk.

Who Pays? Look at Your Lease (FRI Leases)

Even in situations where the landlord agrees to arrange the compliance checks for the whole building to ensure standardisation, don't expect a free ride.

Most modern commercial leases are Full Repairing and Insuring (FRI) leases. Under an FRI lease, the costs of maintaining the building—including all statutory compliance checks like Health and Safety Audits and communal FRAs—are legally passed down to the tenants via the service charge. So, while the landlord might organise the paperwork for the shared spaces, you are still footing the bill.

Beyond Fire: Electrical and Water Compliance

It is vital to understand that the concept of "control" extends to other areas of statutory compliance.

If you have a staff kitchen, bathrooms, or air conditioning systems within your leased area, you are the Duty Holder under HSE ACoP L8, meaning you must arrange your own Legionella Risk Assessments.

In summary: read your lease carefully, but operate under the assumption that if you have the keys and employ the staff, the legal liability rests with you. Do not wait for an inspection to find out you are in breach of the law.
