Since the introduction of the Building Safety Act 2022, fire safety responsibilities have expanded dramatically across the UK construction industry. From design teams and contractors to building owners and facilities managers, organisations must now demonstrate compliance throughout a building’s entire lifecycle, not just at project completion.
Following significant legislative reforms introduced in response to the Grenfell Tower tragedy, organisations involved in the design, construction, refurbishment and management of buildings now face greater responsibility than ever before.
Compliance is no longer simply about meeting building regulations at project completion. It requires a proactive approach that embeds fire safety throughout every stage of a project’s lifecycle.
From maintaining comprehensive records to ensuring competent installation and ongoing maintenance, every stakeholder has a role to play in creating safer buildings.
This guide explores the latest legislative changes, the fire safety systems affected, and how effective planning, quality management and digital documentation help deliver compliant, resilient buildings across complex construction projects.
Why Fire Safety Regulations Have Changed
The UK’s approach to fire safety has evolved over the past decade. While Building Regulations have long set minimum standards for protecting life and property, recent events exposed shortcomings in how fire safety was managed throughout the construction process.
The Grenfell Tower fire in 2017 highlighted widespread issues relating to design decisions, product specification, quality assurance and accountability. The subsequent Hackitt Review concluded that the industry required fundamental cultural change, placing greater emphasis on competence, transparency and responsibility throughout the entire lifecycle of a building.
Rather than relying on compliance at isolated project milestones, legislation now encourages continuous oversight from concept design through construction, handover and occupation.
Construction companies are now expected to demonstrate not only that fire safety systems have been installed correctly, but also that every decision can be evidenced through clear documentation and traceable processes.
Recent Legislation Shaping Fire Safety Requirements
Several pieces of legislation now influence how fire safety installations are managed.
Building Safety Act 2022
The Building Safety Act establishes new responsibilities for duty holders, strengthens regulatory oversight and introduces stricter requirements for information management throughout a building’s lifecycle.
It also reinforces the need for competent professionals, robust quality assurance processes and effective collaboration between project teams.
Fire Safety Act 2021
The Fire Safety Act clarifies the scope of fire risk assessments by ensuring external walls, balconies, cladding systems and entrance doors to individual flats are included where relevant.
Although primarily aimed at occupied buildings, its implications influence design decisions made during construction and refurbishment.
Approved Document B
Approved Document B continues to provide detailed guidance on meeting Building Regulations relating to fire safety.
Recent revisions have strengthened requirements surrounding:
- Means of escape.
- Fire compartmentation.
- Structural fire resistance.
- Fire detection systems.
- Smoke control.
- Firefighter access.
- Materials and external wall systems.
Design teams must ensure these requirements are considered collectively rather than in isolation.
Regulation 38
Regulation 38 requires key fire safety information to be provided to the client or Responsible Person upon completion of construction work.
This information supports ongoing building management by ensuring those responsible for operating and maintaining the building understand its fire safety systems.
Typical documentation includes:
- Fire strategies.
- As-built fire drawings.
- Product specifications.
- Operation and maintenance manuals.
- Testing certificates.
- Commissioning reports.
Regulation 38 also complements the Golden Thread by ensuring critical information continues to support safe building management long after construction has finished.
British Standards and Industry Guidance
Compliance with legislation is supported by numerous British Standards covering fire detection, suppression systems, emergency lighting, smoke control, passive fire protection and ongoing maintenance.
Following recognised standards helps demonstrate competence, consistency and best practice throughout project delivery.
Who Are the Duty Holders Under the Building Safety Act?
Under the Building Safety Act, Duty Holders have clearly defined responsibilities to ensure fire safety is considered throughout design, construction and occupation.
- Client: Appoints competent Duty Holders and ensures projects are properly planned, resourced and managed to achieve compliance.
- Principal Designer: Coordinates the design process, ensuring fire safety risks are identified, managed and integrated across all disciplines.
- Designers: Produce Building Regulations-compliant designs, specify suitable materials and coordinate building systems to minimise fire risk.
- Principal Contractor: Manages the construction phase, overseeing subcontractors, quality assurance and the correct installation of fire safety systems.
- Contractors and Specialist Installers: Install fire safety systems in accordance with approved designs and standards, while maintaining installation records and supporting testing, commissioning and handover documentation.
- Building Owners and Responsible Persons: Following completion, ensure fire safety systems are inspected, maintained and documented throughout the building’s operational life.
Clearly defined responsibilities help maintain accountability and ensure fire safety remains a priority throughout the entire building lifecycle.
The Impact of the Building Safety Act on Fire Safety Installations
The Building Safety Act 2022 represents the most significant reform to building safety legislation in decades. It establishes a new regulatory framework designed to improve the safety of higher-risk buildings while raising standards across the wider construction industry.
Increased Accountability Throughout the Project Lifecycle
One of the most important changes introduced by the Building Safety Act is increased accountability for everyone involved in delivering a building.
Instead of responsibility being concentrated at project completion, duty holders are expected to demonstrate compliance throughout planning, design, procurement, construction and handover.
This means organisations must:
- Maintain accurate project records.
- Demonstrate that compliant products have been specified and installed.
- Record design changes and approvals.
- Verify testing and commissioning activities.
- Ensure fire safety information remains accessible throughout the building’s life.
This continuous record of information forms part of the Golden Thread, creating a transparent audit trail that supports safer decision-making both during construction and after occupation.
Higher Standards for Design and Construction
Fire safety is now expected to be embedded into project planning rather than addressed towards the end of construction.
This requires close coordination between architects, structural engineers, MEP designers, fire engineers, specialist contractors and principal contractors to ensure fire protection measures work together as a complete system.
Key considerations include:
- Early fire strategy development.
- Coordination between passive and active fire protection systems.
- Selecting compliant, tested products.
- Preventing clashes between building services.
- Maintaining fire compartmentation throughout installation.
- Ensuring quality assurance processes verify installation standards before completion.
For turnkey contractors such as Sweet Projects, this integrated approach helps reduce design risk, minimise costly remedial work and ensure compliance is maintained throughout delivery.
The Role of Documentation and the Golden Thread
Robust documentation has become central to modern fire safety management. Rather than simply demonstrating compliance at project completion, organisations are now expected to maintain accurate, accessible records throughout the entire lifecycle of a building.
What Is the Golden Thread?
The Golden Thread is a digital record of key building information that is created during design, updated throughout construction and maintained during occupation.
Its purpose is to ensure that critical safety information remains accurate, accessible and up to date for everyone responsible for the building.
Rather than relying on fragmented paper records or disconnected systems, the Golden Thread brings together information such as:
- Design intent.
- Fire strategies.
- Product specifications.
- Installation records.
- Inspection reports.
- Testing certificates.
- Commissioning documentation.
- Maintenance records.
For fire safety installations, this creates complete traceability, allowing building owners and facilities managers to understand exactly how systems were designed, installed and maintained.
Documentation Required for Fire Safety Installations
Effective documentation supports compliance, simplifies future maintenance and demonstrates that fire safety systems have been installed correctly.
Typical records include:
- Product data sheets and certification.
- Third-party approvals and test evidence.
- Installation records.
- Inspection reports.
- Commissioning certificates.
- Fire strategy documentation.
- As-built drawings.
- Maintenance schedules.
- Operation and maintenance manuals.
- Handover documentation required under Regulation 38.
Maintaining accurate documentation throughout the project not only satisfies legislative requirements but also helps reduce future risk, supports building alterations and ensures fire safety systems continue to perform as intended throughout the life of the building.
What Fire Safety Installations Are Covered by Legislation?
Alongside firefighter facilities such as dry risers, fire hydrants, wayfinding signage and firefighting shafts where required, legislation and guidance place specific requirements on a range of active and passive fire protection systems.
Fire Detection and Alarm Systems
Fire detection and alarm systems provide the earliest warning of a fire, allowing occupants to evacuate safely and emergency services to respond quickly.
To remain compliant, systems must be correctly designed for the building’s intended use, installed by competent professionals and regularly tested and maintained. Accurate records of inspections, servicing and any modifications should also be retained as part of the building’s fire safety documentation.
Fire Suppression Systems
Fire suppression systems help control or extinguish fires before they spread, reducing the risk to occupants and limiting damage to buildings and critical infrastructure.
Depending on the environment, suppression systems may include:
- Sprinkler systems
- Water mist systems
- Gas suppression systems for sensitive environments
- Specialist suppression solutions for high-risk applications
Each system must be designed for its intended purpose, installed in accordance with relevant British Standards and regularly inspected to ensure continued performance.
Passive Fire Protection Measures
Passive fire protection forms the backbone of a building’s fire strategy by helping to contain fire and smoke, protecting escape routes and preserving structural integrity.
Key passive fire protection measures include:
- Fire compartmentation
- Fire stopping around service penetrations
- Fire-resistant walls, floors and ceilings
- Fire doors and associated hardware
- Fire-resistant ductwork and service enclosures
Even minor defects or poorly installed services can compromise compartmentation, making quality assurance and inspection essential throughout construction.
Smoke Control and Ventilation Systems
Smoke is often a greater risk to life than flames themselves. Smoke control systems are designed to remove smoke from escape routes, improve visibility and assist firefighting operations.
These systems must be carefully coordinated with the wider fire strategy, particularly in complex or multi-storey buildings where smoke movement can significantly affect evacuation procedures.
Emergency Lighting and Escape Routes
Emergency lighting ensures escape routes remain visible during power failures or fire incidents, helping occupants evacuate safely.
To remain compliant, emergency lighting systems require regular inspection, functional testing and maintenance. Escape routes must also remain unobstructed throughout both construction and occupation.
Planning Fire Safety Installations from the Start
Successful fire safety management begins long before construction starts. Integrating fire safety from the start helps minimise risk, reduce costly redesigns and ensure compliance can be demonstrated throughout the project lifecycle.
Embedding Fire Safety into Design
Fire safety should be considered as a fundamental design principle rather than a final compliance exercise.
Early collaboration between architects, engineers, fire consultants and contractors helps ensure:
- Fire strategies are developed from the outset.
- Passive and active fire protection systems work together.
- Building services do not compromise compartmentation.
- Firefighter access and means of escape are fully integrated into the design.
- Future maintenance requirements are considered.
Selecting Appropriate Fire Safety Systems
Every building presents different fire risks depending on its size, occupancy and operational requirements.
Selecting suitable systems involves considering:
- Building use and occupancy.
- Fire load and associated risks.
- Applicable legislation and British Standards.
- Product certification and third-party approvals.
- Long-term maintenance requirements.
- Future adaptability of the building.
Choosing tested, compliant products from reputable manufacturers helps reduce installation risks while supporting long-term compliance.
Working with Qualified Specialists
Fire safety systems should only be designed and installed by competent professionals with the appropriate knowledge, training and experience.
Working with qualified specialists like Sweet Projects helps ensure:
- Installations comply with legislation and industry standards.
- Approved products are used correctly.

- Review specifications against current guidance.
- Engage fire engineering specialists where appropriate.
Maintaining up-to-date knowledge reduces the risk of non-compliance and costly project delays.
Product Selection and Certification
Not all construction products offer the same level of fire performance.
To demonstrate compliance, project teams should ensure:
- Products are suitable for their intended application.
- Appropriate third-party certification is available.
- Tested installation methods are followed.
- Product substitutions are properly assessed and approved.
Careful product selection helps maintain the integrity of the building’s overall fire strategy.
Maintaining Compliance After Project Completion
Fire safety responsibilities continue long after practical completion.
Building owners and Responsible Persons should ensure:
- Fire safety systems are regularly inspected and maintained.
- Records remain accurate and up to date.
- Fire risk assessments are reviewed when buildings change.
- Regulation 38 documentation is securely retained and readily accessible.
Providing complete handover information supports ongoing compliance throughout the building’s lifecycle.
How Technology Is Improving Fire Safety Management
Digital technology is transforming how fire safety information is managed, making it easier to demonstrate compliance, improve collaboration and maintain the Golden Thread throughout a building’s lifecycle.

- Independent inspections where required.
- Recording test results and certification.
- Producing comprehensive handover documentation in accordance with Regulation 38.
A structured inspection and testing process provides confidence that fire safety installations comply with legislation while supporting the Golden Thread and long-term building management.
Data Centres & Fire Safety
Data centres present unique fire safety challenges due to the concentration of critical equipment, high electrical loads and the need to maintain continuous operations. Server components can operate at temperatures exceeding 80°C, robust fire protection is essential not only to safeguard personnel but also to protect valuable digital infrastructure and minimise operational downtime.
Recent incidents have highlighted the importance of designing resilient fire protection strategies from the outset. Fires linked to battery energy storage systems and electrical equipment failures have demonstrated how quickly incidents can escalate without appropriate detection, compartmentation and suppression measures.
For this reason, fire safety in data centres extends far beyond regulatory compliance. It requires a carefully coordinated approach that integrates passive fire protection, intelligent detection systems, suppression technologies and ongoing monitoring into a single fire strategy.
Fire Safety Considerations for Data Centres
When delivering data centre projects, fire safety should be embedded into every stage of design and construction. Key considerations include:
- Early fire detection, including aspirating smoke detection (ASD) systems capable of identifying smoke particles before a fire develops.
- Fire compartmentation to contain potential fires within individual rooms or plant areas, limiting damage and protecting critical infrastructure.
- Appropriate fire suppression systems, such as clean agent gas suppression or water mist systems, selected to minimise damage to sensitive electronic equipment.
- Smoke control and ventilation to support safe evacuation and assist emergency services.
- Resilient electrical infrastructure, reducing the risk of equipment failure leading to fire.
- Comprehensive testing and commissioning before handover to verify all fire protection systems perform as intended.
- Ongoing compliance and maintenance, supported by accurate digital records that contribute to the Golden Thread.
