Regulation 38 of the Building Regulations 2010 (as amended) is a critical compliance requirement that governs the handover of fire safety information following construction work in England and Wales. The information ensures the building’s management team knows exactly how to limit a fire’s spread, maintain all safety systems, and execute a safe evacuation.

Regulation 38 generally applies to non-domestic buildings and the common parts of multi-occupied residential buildings where the Regulatory Reform (Fire Safety) Order 2005 will apply post-completion. For Higher-Risk Buildings (HRBs) and complex projects, this process is intrinsically linked to the ‘Golden Thread’ requirements of the Building Safety Act 2022, ensuring continuity of safety management between the construction phase and the occupation phase.

Which Buildings Does Regulation 38 Apply To?

Regulation 38 is triggered primarily by the building’s function or use, not its size, height, or number of stories.

It applies to any building work that falls under the scope of Part B (Fire Safety) of the Building Regulations and where the finished building will be subject to the Regulatory Reform (Fire Safety) Order 2005 (FSO).

In simple terms:

• It applies to the majority of non-domestic premises, regardless of size or height:
  • Offices, shops, factories, and warehouses.
  • Hotels and B&Bs.
  • Hospitals, schools, and university buildings.
• It applies to the common parts of multi-occupied residential buildings:
  • The entrance lobbies, corridors, stairs, and plant rooms in blocks of flats or apartments.
• It does NOT apply to:
  • A private, single-family dwelling (a purely domestic premises).

While the level of detail required in the Reg 38 file significantly increases for large, complex, or high-rise buildings (especially Higher-Risk Buildings under the Building Safety Act), the initial legal requirement to provide the file is based on the building’s operational use under the FSO.

When is the Fire Safety Information (Regulation 38 File) Required?

Regulation 38 applies when building work:

1. Consists of or includes the erection or extension of a relevant building.
2. Is carried out in connection with a relevant change of use of a building.
3. Imposes a requirement in relation to Part B (Fire Safety) of Schedule 1 of the Building Regulations.

The legislation mandates a specific handover timeline:

The person carrying out the work must give the fire safety information to the Responsible Person no later than the date of completion of the work or the date of occupation of the building or extension, whichever is the earlier.

Crucially, the Responsible Person must also issue a notice acknowledging receipt and confirming the information is sufficient for them to understand, operate, and maintain the building. Failure to provide complete, accurate, and timely information can result in prosecution and delay handover and occupation.

What is the Regulation 38 File?

Regulation 38 legally requires the person carrying out building work (typically the Principal Contractor or Client) to prepare and deliver a comprehensive package of “Fire Safety Information” to the Responsible Person for the building.

This file serves as the definitive, “as-built” record of the building’s fire safety strategy. It must contain sufficient detail about the design, construction, services, fittings and equipment provided to allow the Responsible Person to safely operate and maintain the premises.

The file’s content typically includes, but is not limited to:

• As-Built Fire Strategy Drawings: Comprehensive, dimensioned drawings indicating final escape routes, maximum occupant capacity for each area, and the precise location of all critical fire safety equipment, including manual call points, alarm sounders, and fire extinguishers.
• Passive Fire Protection System Records: Detailed documentation showing the exact locations, fire resistance periods (FR), and integrity/insulation (EI) ratings of all fire-separating elements (walls, floors, ceilings), and precise certification records for cavity barriers and fire-stopping penetration seals.
• Active Fire System Technical Manuals: Full operating and maintenance manuals for all active systems (e.g., fire detection and alarm systems, voice alarm systems, sprinklers, and smoke control systems), including cause and effect logic matrices and mandatory routine maintenance schedules as per relevant British Standards.
• Fire Component Certification and Installation Data: A register of all installed fire-critical products (e.g., fire doorsets, self-closers, emergency lighting units, fire-rated glazing), including manufacturer data sheets, product fire test certificates (where applicable), and details of their proper installation methods.
• Fire Safety Management Assumptions & Procedures: A documented list of all necessary operational controls assumed in the fire design (e.g., security access protocols, fire patrol frequencies, or specific evacuation procedures) to ensure the building performs as intended under fire conditions.

Regulation 38 File Format Requirements

The effectiveness of the Regulation 38 file relies heavily on its format and structure, ensuring the Responsible Person can easily access, understand, and use the information.

• Accessibility: While historically submitted in hard copy, the information is now almost exclusively required in digital format (e.g., structured PDFs or within a Common Data Environment/CDE).
• Logical Structure: The file must be clearly indexed and grouped to mirror the building’s fire safety strategy, enabling quick cross-referencing between system descriptions, maintenance schedules, and as-built drawings.
• The Golden Thread: For Higher-Risk Buildings (HRBs) and increasingly for all complex projects, the Regulation 38 data must align with the principles of the Golden Thread—meaning the information is accurate, up-to-date, understandable, and accessible throughout the building’s life cycle. This emphasizes the need for well-structured, named files and clear version control.

Why is the Regulation 38 File Critical?

The core purpose of Regulation 38 is to bridge the gap between building completion and facility management, providing the Responsible Person with the tools necessary to fulfil their duties under the Regulatory Reform (Fire Safety) Order 2005 (FSO).

The file is essential because it allows the Responsible Person to:

1. Understand the Strategy: Grasp the building’s intended fire safety design and how various passive and active systems work together.
2. Maintain Systems: Establish accurate and effective maintenance regimes for all life-safety critical equipment and materials.
3. Conduct Fire Risk Assessments (FRAs): Use the as-built information as the foundation for a suitable and sufficient FRA, which is a legal requirement under the FSO.

Recent changes, especially those linked to the Building Safety Act 2022, emphasize the need for accurate, digitally accessible information (part of the “Golden Thread”), making the quality and precision of the Regulation 38 document more important than ever.

Outsourcing Technical Documentation

For contractors and project managers, compiling the Regulation 38 file often presents a significant challenge due to time pressure, technical expertise and need to focus on on-site duties. Outsourcing to specialist technical writing experts becomes invaluable in these situations to ensure that documentation is accurate, concise, delivered on time and cost effective.
