Every non-domestic building in the UK has a legal duty to carry out a fire risk assessment, yet many businesses aren't sure how often it's needed, who's responsible, or what it actually costs. Here's a clear breakdown of what's involved, who needs one, and how CTS can help you stay compliant without the jargon.
Every non-domestic building in the UK has a legal duty to keep its people safe from fire, and that starts with a proper fire risk assessment. Our qualified assessors identify hazards, flag what needs fixing, and give you a clear, actionable report, so you know exactly where you stand and what to do next.
A fire risk assessment is a systematic review of a building to identify fire hazards, the people at risk, and the measures needed to reduce that risk to an acceptable level. It covers everything from escape routes and fire doors to alarm systems, signage, and staff training. Under the Regulatory Reform (Fire Safety) Order 2005, it’s a legal requirement for almost every non-domestic building in England and Wales, and the “responsible person” for the premises must ensure one is carried out and kept up to date.
If you’re responsible for a non-domestic building, in most cases the answer is you. That includes:
The specifics vary by building type and occupancy, but the underlying legal duty is the same: identify the risk, document it, and act on it.

There’s no single fixed interval set out in law. Instead, the assessment must be reviewed regularly and whenever something changes, whichever comes first. In practice, most low-risk premises are reviewed annually, while higher-risk buildings such as care homes or sites with vulnerable occupants are reviewed more frequently. A new assessment is also required after any significant change to the building’s layout, use, or occupants.
If you’re not sure whether yours is overdue, we can tell you exactly where you stand during an initial site visit.
Responsibility sits with the “responsible person,” usually the employer, building owner, or managing agent, whoever has control of the premises. This person doesn’t have to carry out the assessment themselves, but they are legally accountable for making sure a suitable and sufficient one exists and is acted upon. Getting this wrong can mean enforcement action from your local fire authority, invalidated insurance, or prosecution following an incident.
Cost depends on the size, complexity, and use of the building; a small office will cost considerably less to assess than a multi-storey care home or HMO with several communal areas. Rather than quote a generic figure that may not reflect your building, we provide a fixed price after an initial conversation about your site, so you know exactly what you’re paying for before you commit.

We keep our fire risk assessment service independent from the works it may recommend, so you can trust the findings are about your safety and compliance, not selling you more than you need.
