Why choose Surefire
Fire performance where space is constrained
Surefire provides a fire-rated portable building solution for projects where site layout does not allow the preferred separation distance between temporary and surrounding buildings.
Security built in
Robust galvanised steel construction, high-security doors and anti-vandal security features provide dependable protection for people, equipment and assets.
Built for repeated use
Durable construction supports repeated deployment across changing sites and project requirements.
Relocate and reuse
Surefire is designed to be repositioned and redeployed as requirements change, supporting a more flexible approach to temporary accommodation.
Configure around your requirements
Different sizes, internal arrangements and fit-out options allow Surefire to be adapted around how the finished space needs to work.
Enhanced efficiency when required
Where greater thermal and operational energy performance is required, Surefire can be specified as Surefire Eco.
When is fire-rated site accommodation required?
The fire-performance specification required for temporary accommodation depends on its position, configuration and the findings of the site fire-risk assessment.
A fire break of at least 6 metres
The Joint Code of Practice recommends providing as wide a fire break as reasonably practicable, aiming for at least 10 metres and maintaining a minimum of 6 metres wherever possible.
Where buildings are stacked vertically, additional fire-resistance requirements apply. The floor and roof assembly must achieve 30-minute REI fire resistance, with supporting members achieving 30-minute R fire resistance.
A fire break of less than 6 metres
Where it is not reasonably practicable to maintain a fire break of at least 6 metres, temporary buildings must meet the enhanced fire-performance criteria set out in Section 13.3 of JCoP 10.2.
Properly maintained buildings manufactured before 1 January 2025 that comply with Section 13.3 of the Ninth Edition may continue to be used until retired. Buildings manufactured after that date must meet the requirements of the current edition.
Surefire accommodation is developed for sites where enhanced fire performance is required, helping customers select an appropriate specification around their site layout, building configuration and fire-safety assessment.

Doors
High-security fire-rated doors.
Windows and security
Aluminium windows with fire-rated anti-vandal security shutters. Double-glazed UPVC windows can be specified where required.
Roof
Fully welded galvanised steel roof construction.
Insulation
Non-combustible glass-wool fibre insulation to roof and wall cavities.
Stacking and levelling
Telescopic jack legs support levelling and double-stacked configurations.
Lifting and relocation
Designed to support transport, positioning and repeated relocation.
Layout and finish
Available in different sizes and internal arrangements, with bespoke finishes and colour options.
Compliance & performance
JCoP Section 13.3
Surefire is designed for temporary building applications where a fire break of at least 6m cannot reasonably be achieved, meeting the relevant requirements of JCoP Section 13.3.
JCoP Section 13.6
Surefire can also be used in vertically stacked configurations meeting the relevant requirements of JCoP Section 13.6.
Fire performance
Surefire incorporates enhanced fire-performance construction, including fire-rated doors and security features.
Site and deployment requirements
Surefire is designed as a transportable and relocatable building and can be specified around the requirements of the site, intended use and required fire-performance strategy.
HSG168
Surefire can be specified with reference to relevant HSE fire-safety guidance for construction environments.
Energy performance
Thermal and operational energy performance depends on the final building configuration and specification. Where enhanced performance is required, the Surefire Eco specification provides additional insulation and energy-efficiency measures.
Configure Surefire around your requirement
Surefire can be fitted out around how the finished space will be used, with options available across internal layout, building services, finishes and thermal performance.
Internal layouts
Partitions and internal configurations to suit the required use.
Electrical & IT
Electrical and data provision configured around operational requirements.
Plumbing
Plumbing and welfare facilities available where required by the application.
Heating & cooling
Heating, cooling and ventilation options to support comfort and day-to-day use.
Finishes & branding
A choice of internal and external finishes, including bespoke colour and branding options.
Enhanced insulation
Additional insulation can be specified where greater thermal performance is required.
Surefire Eco
Enhanced thermal performance on the Surefire platform
Surefire Eco builds on the same fire-performance, security and relocatable characteristics as standard Surefire, with an enhanced specification designed to improve thermal performance and operational energy efficiency. Eco variants
What the Eco specification adds:
- Enhanced roof insulation
- Enhanced wall insulation
- Insulated base
- Energy-efficient electrical provision
- Double-glazed UPVC windows available as an upgrade
- Same Surefire fire-performance, security, stacking and JCoP positioning
