Hot work controls: lessons for property managers from an HSE prosecution

What HSE has newly reported

On 30 October 2026, the Health and Safety Executive published the outcome of a prosecution concerning a roof fire at an apartment building under construction in Staines-upon-Thames, Surrey. The incident happened on 26 July 2024; the court hearing was on 29 October 2026. HSE reported that welding sparks ignited exposed insulation and four workers escaped using a single roof opening and ladder. Its investigation found failures to plan, manage and monitor the hot work, with no task risk assessment, method statement or welding permit in place despite company procedures requiring them. HSE also reported absent alarm arrangements and extinguishers. The contractor pleaded guilty to a construction-management offence and was fined. These are published findings, not speculation about an ongoing fire.

Why this matters beyond the construction site

The new development is the enforcement report, not a new rule introduced this week. For property owners and managing agents appointing contractors, it provides a practical reason to check whether agreed precautions are actually implemented. The Surrey incident should not be presented as a Kent or London fire. Our discussion concerns projects in England; the applicable legal framework and responsibilities must be checked for work elsewhere. Do not assume a building's normal management arrangements automatically cover a temporary work area or construction activity.

Start with the work, not just the paperwork

HSE's process-fire guidance identifies hot work as an ignition source and describes precautions such as removing combustible materials, providing suitable extinguishers and watching carefully during the work. We recommend asking the contractor to identify the activity, location, surrounding materials and precautions before it begins. If a proposal changes, establish who will review the risk and authorise the revised arrangement. A generic document naming the project does not demonstrate that the conditions at the particular work location have been considered.

A permit supports assessment; it does not replace it

HSE explains that a permit-to-work system communicates the work, timing, hazards, controls and responsibilities. It is not a substitute for a robust risk assessment, nor does issuing a permit itself make a job safe. For work needing this control, we recommend confirming who may authorise it, who checks that precautions are in place and how completion and handover are recorded. Agree monitoring during and after the activity using the appropriate construction guidance and task assessment; do not borrow a watch period from an unrelated job.

Protect the people already using the building

HSE's construction fire-safety guidance says work in occupied buildings must not interfere with existing escape routes, fire separation, alarms, dry risers or sprinkler systems. The arrangements need to reflect the changing work. For a landlord or agent in Gillingham, Medway, elsewhere in Kent or South East London, we recommend discussing how the contractor's area interfaces with residents, staff and neighbouring occupiers. Keep reporting contacts and emergency instructions clear. These are premises-specific questions, not new local requirements or permission to alter protective systems.

Get the right support before commissioning work

If existing FRA findings are unclear, 1st Aid Fire can discuss an agreed-scope explanation and next steps. Construction-phase planning, hot-work authorisation and specialist technical decisions need the appropriate competent people; a desktop FRA review does not approve a contractor's method or certify site safety.
