If you’re a fire engineer or fire consultant working in or around central London, you already know that a Fire Strategy Report is more than a compliance document. It’s a technical justification, a design tool, and often the difference between a smooth approval process and months of back-and-forth with Building Control or the London Fire Brigade.
This article explains what a Fire Strategy Report is, how it fits within UK Building Regulations, and what matters most when delivering one for complex London projects.
What Is a Fire Strategy Report?
A Fire Strategy Report sets out how a building will meet the fire safety requirements of the Building Regulations 2010, primarily Approved Document B (ADB).
In practice, it brings together:
- Life safety principles
- Means of escape
- Fire compartmentation
- Structural fire protection
- Fire detection and alarm systems
- Smoke control
- Firefighting access and facilities
For London schemes, the report often needs to address non-standard layouts, mixed-use buildings, basements, heritage constraints, and tight site boundaries.
Where Fire Strategy Fits in UK Building Regulations
Under UK Building Regulations, fire safety is covered mainly by:
- Approved Document B – Volume 1 & 2
- Regulation B1 to B5
- Regulation 38 (fire safety information)
- Regulation 7 (materials and workmanship)
A Fire Strategy Report demonstrates how the design achieves compliance, whether by:
- Following ADB guidance, or
- Using a fire engineered approach where prescriptive guidance is not suitable
In central London, full ADB compliance is often impractical. This is where a clearly justified, well-structured fire strategy becomes essential.
Why Fire Strategy Reports Matter More in Central London
Central London projects face challenges you don’t see elsewhere:
- Constrained escape routes
- Deep or multiple basements
- Adjoining structures on all sides
- Air rights developments
- Listed buildings and conservation areas
- Higher scrutiny from Building Control and Fire Authorities
A generic fire strategy will not survive this level of review. Authorities expect:
- Clear assumptions
- Logical engineering arguments
- Consistency between drawings, calculations, and narrative
For higher-risk buildings, expectations increase again under the Building Safety Act 2022, particularly at Gateway stages.
Key Components of a Robust Fire Strategy Report
A strong Fire Strategy Report for UK Building Regulations should include, at minimum:
1. Building Description
- Use, height, floor areas, and occupancy
- Relevant risk profile
- Phasing if applicable
2. Means of Escape
- Travel distances
- Exit capacities
- Stair design and numbers
- Evacuation strategy (simultaneous, phased, or stay put)
3. Fire Compartmentation
- Compartment sizes
- Fire resistance periods
- Treatment of penetrations and interfaces
4. Fire Detection and Alarm
- System category (BS 5839-1 or BS 5839-6)
- Cause and effect overview
5. Smoke Control
- Natural or mechanical systems
- Design standards (e.g. BS 9991, BS 9999)
- Interfaces with architecture and MEP
6. Firefighting Facilities
- Firefighting shafts
- Access distances
- Water supplies
7. Compliance and Deviations
- Explicit identification of departures from ADB
- Engineering justification for each
This clarity is critical when coordinating with Building Control bodies operating across Greater London.
Common Issues Seen in Fire Strategy Reviews
From experience across London boroughs, the most frequent problems include:
- Strategies that don’t match architectural drawings
- Assumptions not supported by calculations
- Smoke control designs without operational detail
- Late changes not captured in updated reports
- Poor coordination with Regulation 38 information
A Fire Strategy Report should evolve with the design. Static documents rarely hold up under scrutiny.
Fire Strategy Reports and Planning vs Building Control
In London, fire strategy input is often required at planning stage, particularly for:
- Tall buildings
- Residential schemes
- Mixed-use developments
However, a planning fire statement is not a Building Regulations fire strategy. Fire engineers and consultants need to manage this transition carefully, ensuring:
- Early concepts are technically realistic
- Commitments made at planning are deliverable at detailed design
Failing to align the two can create major delays later.
Final Thoughts
A Fire Strategy Report for UK Building Regulations is not a tick-box exercise, especially in central London. It’s a technical document that must stand up to detailed review by Building Control, fire authorities, and increasingly, the Building Safety Regulator.
For fire engineers and fire consultants, the focus should always be on:
- Clear reasoning
- Practical solutions
- Strong coordination with the wider design team
Get those right, and the strategy becomes a tool that supports the project, not an obstacle.
