Hot Works Permit Template

Hot works permits are written authorisations for activities involving heat, sparks or open flame on UK construction sites. Welding, grinding, soldering, brazing and cutting all qualify as hot works. Hot works are the single largest cause of preventable construction fires - a permit-to-work system is industry standard practice and frequently insurance-mandated.

What is a hot works permit template?

A formal document that authorises specific hot works at a specific location for a specific time period, with specific safety controls in place. The permit is signed by the authorising person before work starts and signed off by the worker on completion (with a fire watch period afterwards).

Who needs one?

Any UK contractor whose work involves heat, sparks or open flame on a construction site. Most main contractors require permits for all hot works. Insurance underwriters typically mandate them. The Principal Contractor authorises permits; individual contractors comply with them.

Example permit: Welding repairs to steel beam, 3rd floor, north elevation. Duration: 3 hours. Pre-work checks: combustibles removed (insulation rolled back 5m, plywood sheeting protected), 2x CO2 extinguishers positioned, fire blanket within reach, ventilation confirmed.

Common mistakes

  • !Permits issued without verifying pre-work fire safety checks
  • !No fire watcher nominated or fire watcher leaves before 60-minute post-work period
  • !Permits covering an entire shift rather than the specific work activity
  • !Combustibles not actually removed despite permit saying they were
  • !Workers not informed about emergency procedures specific to the work area

FAQ

What activities require a hot works permit?+

Welding, grinding, cutting, soldering, brazing, blow torches, any work that produces sparks, flame or significant heat.

Who issues the permit?+

Typically the Principal Contractor's site manager or H&S coordinator. Anyone authorised to control the work area.

How long does the permit last?+

Typically same shift only - issue at start of work, sign off at end. Multi-day work needs renewed permits each day.

What is the 60-minute fire watch?+

Industry standard - hot works embers can smoulder for hours before flames appear. A trained fire watcher monitors the area for 60 minutes after work ends to catch any developing fire.

Are hot works permits insurance-mandated?+

Most UK contractor insurance policies require permit-to-work systems for hot works. Failure to use them can void insurance cover for fire damage.
