Active Fire Protection Tenders in the UK: The Complete Guide

Active fire protection refers to systems that require mechanical, electrical or electronic operation to detect fire, warn occupants or control fire development.

These systems are typically designed by fire engineers and building services consultants as part of the building's overall fire strategy.

In most commercial environments, active systems operate alongside passive fire protection measures such as:

• compartmentation systems
• fire stopping
• fire doors
• fire-rated glazing

For example:

• fire alarms detect fire conditions and trigger evacuation procedures
• smoke control systems manage smoke movement through escape routes
• sprinkler systems suppress fire growth
• emergency lighting ensures safe evacuation during power loss

Because these systems interact with each other, they are frequently procured as part of coordinated fire protection programmes.

Projects involving active systems often run alongside passive protection works such as Fire Stopping Tenders in the UK or Fire Door Installation & Remediation Tenders.

Active fire protection includes several specialist disciplines, each governed by its own technical standards and installation practices.

Fire Alarm Systems

Fire alarm systems provide early warning of fire conditions through automatic detection and manual call points.

Modern commercial alarm systems often integrate with other building systems including:

• smoke control systems
• lift controls
• fire door release mechanisms
• voice alarm systems

Installation, commissioning and tendering considerations for these systems are explored in Fire Alarm System Tenders in the UK.

Sprinkler Systems

Automatic sprinkler systems suppress fires by discharging water directly onto the fire source once heat activates sprinkler heads.

They are widely used in:

• warehouses and logistics facilities
• residential high-rise buildings
• retail environments
• commercial office developments

Sprinkler systems are often installed as part of building compliance requirements or insurance conditions, particularly in high-risk environments such as storage facilities.

Contractor strategy and procurement considerations for these systems are explored in How to Win Sprinkler System Tenders.

Smoke Control Systems

Smoke control systems manage smoke movement during a fire incident to protect escape routes and support evacuation.

These systems may include:

• mechanical smoke ventilation
• natural smoke vents
• stair pressurisation systems

Smoke control systems are particularly common in residential towers, atrium buildings and underground structures where smoke accumulation presents significant life safety risks.

Tendering and procurement considerations are explored in Smoke Control System Tenders Explained.

Fire Suppression Systems

In environments where water-based sprinklers are not suitable, alternative suppression systems may be used.

Examples include:

• gas suppression systems
• water mist systems
• foam suppression systems

These systems are commonly installed in:

• data centres
• plant rooms
• energy facilities
• critical infrastructure environments

Procurement considerations are explored in Fire Suppression System Procurement in Commercial Buildings.

Emergency Lighting Systems

Emergency lighting systems provide illumination for escape routes during a power failure caused by a fire incident.

These systems typically cover:

• escape corridors
• staircases
• emergency exits

These installations are required in most commercial buildings to ensure occupants can evacuate safely if normal lighting fails.

Compliance and procurement considerations are explored in Emergency Lighting Compliance & Tendering.

Fire Extinguishers

Portable fire extinguishers provide manual fire suppression capability during the early stages of a fire incident.

They are installed throughout commercial premises and require routine inspection and servicing to maintain compliance.

Maintenance and contract structures are explained in Fire Extinguisher Servicing Contracts Explained.

System	Primary Function	Typical Environments
Fire Alarms	Detect fire and warn occupants	Offices, residential, healthcare
Sprinklers	Suppress fire development	Warehouses, high-rise buildings
Smoke Control	Manage smoke movement	Residential cores, atriums
Suppression Systems	Protect specialist risks	Data centres, plant rooms
Emergency Lighting	Support evacuation	All commercial buildings
Fire Extinguishers	Early-stage suppression	Most occupied premises

Each system supports a different stage of fire response, and effective fire strategies rely on their coordinated operation.

Active fire protection systems must comply with a range of British Standards and industry guidance documents.

Examples include:

• BS 5839 — Fire detection and fire alarm systems
• BS EN 12845 — Fixed firefighting systems (sprinklers)
• BS 7346 — Smoke control systems
• BS 5266 — Emergency lighting systems

Compliance with these standards affects system design, installation methods, commissioning procedures and long-term maintenance requirements.

Tender documentation should clearly reference the applicable standards to ensure contractors price compliant installations.

Active fire protection systems rarely operate independently. In most commercial buildings they function as part of an integrated fire safety strategy.

For example, in a typical office or residential development:

• a fire alarm detector activates when smoke is detected
• the alarm system signals evacuation warnings
• smoke control systems activate ventilation to remove smoke
• emergency lighting illuminates escape routes
• sprinkler systems suppress fire growth

At the same time, passive fire protection measures such as compartmentation and fire doors help contain the fire within specific building zones.

This coordinated approach ensures occupants can evacuate safely while preventing fire spread.

Because these systems interact closely, installation projects often require coordination between several specialist contractors.

Active fire protection projects are usually procured through structured commercial tender processes.

These tenders may be issued by:

• developers
• managing agents
• main contractors
• facilities management providers

The tender scope may involve:

• new installations
• system upgrades
• remedial compliance works
• long-term maintenance contracts

Because different systems involve different disciplines, tender documentation must clearly define:

• system design requirements
• compliance standards
• integration requirements
• commissioning expectations

Without this clarity, contractors may interpret scope differently, resulting in inconsistent pricing.

Clients preparing tenders for active fire systems should ensure the documentation includes several key elements.

Fire Strategy Documentation

The building fire strategy defines the role of each fire protection system within the life safety design.

It typically establishes:

• system categories
• evacuation strategy
• integration requirements
• building zoning logic

Technical Specifications

Tender documents should clearly identify:

• applicable British Standards
• system performance requirements
• equipment specifications

System Layout Drawings

Tender documentation may include:

• device layouts
• plant equipment locations
• cable routing drawings

Incomplete drawings often result in inconsistent tender submissions.

Integration Requirements

Active fire systems frequently interact with other building systems.

Tender documentation should clearly define:

• alarm interfaces
• smoke control activation logic
• sprinkler monitoring signals

Contractors bidding for active fire protection work must demonstrate technical capability as well as installation experience.

Clients may evaluate submissions based on several criteria:

• compliance with technical specifications
• contractor experience and references
• system integration capability
• commissioning procedures
• overall cost and programme delivery

Contractors seeking guidance on improving their tender success rates can refer to How Fire Contractors Can Win More Commercial Tenders.

Active fire protection systems require regular inspection, testing and maintenance to remain compliant throughout a building's lifecycle.

Typical maintenance activities include:

• alarm system testing
• sprinkler inspections
• emergency lighting discharge tests
• smoke control servicing
• extinguisher inspections

Many commercial organisations therefore tender long-term maintenance contracts in addition to installation works.

Maintenance programmes ensure that systems continue to operate correctly and remain compliant with relevant fire safety regulations.

Several recurring issues affect active fire protection tenders.

Incomplete System Design

Where design documentation is incomplete, contractors may price assumptions rather than defined scope.

Poor Coordination Between Systems

Active fire systems frequently interact with passive fire protection and building services.

Poor coordination between disciplines can cause installation conflicts.

Informal Procurement Processes

Email-based tendering can lead to inconsistent contractor responses and poor comparison between submissions.

Structured procurement approaches significantly reduce these issues.

Structured procurement platforms are increasingly used to improve how specialist fire protection work is sourced and evaluated.

These platforms allow clients to:

• define scope clearly
• standardise contractor responses
• compare submissions consistently
• maintain auditable procurement records

For contractors, structured procurement improves visibility of relevant commercial opportunities while ensuring submissions are evaluated using consistent criteria.

Commercial organisations often need to source specialist contractors across several active fire disciplines.

Structured procurement platforms allow clients to identify qualified contractors and run tenders that clearly define system scope and compliance requirements.

For contractors, identifying relevant commercial fire protection opportunities can be difficult when procurement is fragmented across multiple channels.

Structured tender marketplaces provide visibility of opportunities aligned with specific fire protection disciplines and allow contractors to submit responses through standardised procurement frameworks.

What is the difference between active and passive fire protection?

Active fire protection systems detect, control or suppress fires through mechanical or electrical operation. Passive fire protection relies on fire-resistant construction to contain fire and smoke.

Are active fire systems usually tendered together?

Some projects combine several systems within a single package, but many systems are tendered separately due to the specialist expertise required.

Who designs active fire protection systems?

Systems are usually designed by fire engineers or building services consultants as part of the building's fire strategy.

Do active fire systems require regular maintenance?

Yes. All active fire protection systems require regular inspection, testing and maintenance to remain compliant.

Why is structured tendering important for active fire projects?

Structured procurement ensures contractors are pricing the same system scope and allows clients to compare submissions consistently.
