Construction sites face a range of fire hazards, from flammable materials to hot works and temporary electrics. A Fire Risk Assessment (FRA) is not only best practice but a legal requirement under UK fire safety law. It’s an essential tool for identifying risks, protecting workers and preventing costly incidents.

In this guide, we explain what a Fire Risk Assessment involves, the key legal duties under CDM 2015 and the Fire Safety Order 2005, how to complete an FRA effectively, and how Majestic Construction supports clients with full fire safety compliance.

  • Fire Risk Assessments are a legal requirement on construction sites under UK regulations, helping identify fire hazards, protect workers and ensure compliance with laws such as the Regulatory Reform (Fire Safety) Order 2005 and CDM 2015.
  • An effective assessment follows a structured process, including identifying hazards and people at risk, implementing control measures, creating emergency plans and regularly reviewing documentation to maintain safety and compliance throughout the project.

What is a Fire Risk Assessment and why is it important?

A Fire Risk Assessment is a structured process used to identify fire hazards, evaluate risks and outline the control measures required to prevent fire incidents. It ensures all persons on site understand the emergency arrangements and that fire safety measures are properly maintained.

FRAs are vital because they:

  • Are legally required under CDM 2015 and the Fire Safety Order 2005
  • Reduce the risk of fires caused by hot works, storage and electrical faults
  • Support safe evacuation planning and staff training
  • Protect construction firms from enforcement and financial loss

Majestic Construction provides comprehensive Fire Risk Assessments for construction projects of all sizes.

Legal requirements for FRAs in construction

Fire safety in construction is governed by several key regulations:

  • The Regulatory Reform (Fire Safety) Order 2005: Requires all sites to maintain a current FRA and appoint a responsible person to manage fire safety.
  • CDM 2015: Principal contractors must include fire safety measures within the Construction Phase Plan and oversee compliance.
  • Health and Safety at Work Act 1974: Employers must assess and control fire risks to protect workers and the public.

Failure to complete or maintain an FRA can lead to HSE enforcement, fines and even project shutdowns.

How to conduct a Fire Risk Assessment

An effective FRA follows a systematic approach:

Step 1: Identify fire hazards

Review potential ignition sources such as hot works and temporary electrics, and identify combustible materials like timber or insulation.

Step 2: Identify people at risk

Consider all persons on site, including subcontractors, visitors and the public, as well as vulnerable groups such as lone or night workers.

Step 3: Evaluate risks and apply controls

Store flammable materials safely, enforce Hot Works Permits, install fire extinguishers, and ensure electrical systems are regularly tested and maintained.

Step 4: Create an emergency plan

Define escape routes, muster points and communication procedures. Display fire action notices and conduct fire drills to ensure all workers understand what to do.

Step 5: Record and review regularly

Keep FRA documentation on site and update it when site conditions change. Schedule regular reviews to maintain compliance throughout the project.

Common fire safety mistakes and how to avoid them

  • Not completing an FRA: Carry out and update FRAs from the start of every project.
  • Poor storage of flammable materials: Designate secure fire-safe zones for fuels and chemicals.
  • Lack of equipment: Provide fire extinguishers and train staff in their use.
  • No worker training: Deliver toolbox talks and fire safety inductions to all personnel.
