Construction Fire Risk Assessment
What is a Construction Fire Risk Assessment?
A Construction Fire Risk Assessment is a structured, legal requirement that evaluates the fire risks on a live construction site, not the finished building.
It’s about identifying how fire could start and spread during the construction phase, assessing whether the right precautions are in place, and recommending what needs to change to keep people safe and protect the project.
Havio carries this out on behalf of the Responsible Person (typically the Contracts Manager or Construction Director).
If you’re working on a project over £2.5m, or anything considered high risk, you’re likely signed up to the Joint Code of Practice.
You’ll also be legally bound by the Regulatory Reform (Fire Safety) Order 2005.
Failure to comply puts your project, reputation, and insurance position at serious risk.
We don’t just look at the paperwork. We assess the real-world site conditions, logistics, and materials in play.

In these short videos, we cover the most common questions we get asked about Construction Fire Risk Assessments
The need for a Construction Fire Risk Assessment
There are three key reasons this matters, and not one of them is optional:
-
Legal:
If you’re the Responsible Person, it’s your duty to ensure a suitable and sufficient fire risk assessment is in place, and kept updated. This isn’t a one-off tick-box. -
Financial:
A fire on site can devastate a business. Delays, insurance complications, legal action, and ruined client relationships. It’s a commercial risk you really can’t afford to ignore. -
Moral:
Lives are at stake here. Fire risks are real, especially with hot works, temporary electrics, and fast-moving logistics.
Common issues we find on site
Electrical problems are often an ignition source, and overlooked.
Most sites either don’t have a valid assessment at all, or it’s been handed to a site manager who doesn’t know what to look for. That’s not good enough, because we’re seeing issues like this all the time.
- Poor compartmentation of temporary fire escape routes
- Over-extended travel distances
- Inappropriate or missing fire extinguishers
- Fire alarm setups that don’t match site scale or phase
- Outdated or missing fire signage
- Flammable storage areas too close to ignition sources
- Excessive use of hot works when alternatives exist
Why choose Havio?
Because we know construction, and we know fire. You need both.
Our team blends deep site experience with technical fire knowledge (not just theory). Our assessors have completed specialist training in construction fire safety and are backed by senior Health & Safety expertise. They’ve got deep site experience with technical fire knowledge. We’ve also built a dedicated Fire Risk Assessment tool into Altitude to help them.
We’re not fire engineers focused on completed buildings. We focus on the risks during the build, where things change fast and site-specific insight matters.
Here’s how we do it:
- We start where possible at pre-construction, carrying out an initial risk review during tender or design stage. This is so you can plan and cost requirements like stair cores or fire-resistant hoardings before they become last-minute problems.
- We then complete a full fire risk assessment on site, giving you a detailed action plan.
- From there, we provide ongoing reviews throughout the construction period, or help you train your own team to maintain the standard.
Our Fire Risk Assessment process
1. Site visit and survey
Depending on the stage of construction, we will visit your project to complete a site survey to gather the information to allow for the fire risk assessment to be completed.
2. Create the Fire Risk Assessment
We will request proposed building drawings so we can write the fire risk assessment with a view on what is there in the present but with one eye in mind on how the project will change in the months ahead.
3. Provision of document
Once drafted, we will send your construction fire risk assessment in word format. This document will then be the responsibility of the on-site manager to keep updated.
4. Document maintenance responsibility
Havio can be requested to update this document, although we encourage on-site management to take responsibility for this as they are always on-site.
5. Competent Person support
If you have access to our competent person service, we will be on hand to provide support on fire safety-related issues throughout your construction project.
