Fire Safety Equipment Buying Guide

Fire safety equipment for UK buildings is selected against three things: the building type, who uses it, and the fire risk assessment required by the Regulatory Reform (Fire Safety) Order 2005. For most non-domestic premises that means a BS 5839-1 fire detection and alarm system, BS 5266 emergency lighting, BS 5306 fire extinguishers, and passive fire protection such as intumescent fire and smoke seals on fire doors. This guide explains how to choose each, in plain terms, so you can specify a compliant set of products with confidence.

Quick Decision Summary

Use this summary for fast procurement decisions before reviewing the full guidance below.

  • Best for: Commercial buildings, HMOs, hotels and managed properties that need a BS 5839-aligned alarm system, emergency lighting and certified passive fire protection.
  • Avoid if: You only need single-room domestic smoke-alarm advice with no compliance obligations — a standalone BS 5839-6 alarm is usually enough.
  • Recommendation: Start from your fire risk assessment, fix the alarm system category (M / L1–L5 / P), then add emergency lighting, extinguishers and fire-door seals, and book scheduled maintenance from day one.

Key Points to Remember

Start from the fire risk assessment

The Fire Safety Order requires the 'responsible person' to hold a current fire risk assessment. It sets the alarm category and equipment you actually need — specify products against it, not from a generic checklist.

Match the alarm system to the building (BS 5839)

Non-domestic premises follow BS 5839-1 (categories M, L1–L5, P1–P2); domestic and HMO premises follow BS 5839-6 (grades A–F, categories LD1–LD3). The category decides how many detectors and which type.

Add emergency lighting and extinguishers

Escape routes need BS 5266-1 emergency lighting; extinguishers are selected by fire class (A, B, C, electrical, F) to BS 5306. Both are part of a compliant set, not optional extras.

Don't forget passive fire protection

Fire doors only perform if gaps are sealed: intumescent fire and smoke seals (e.g. Astroflame) expand in heat to stop fire and smoke spread. Check certification and fit them to every fire door.

Who is responsible, and what does the law require?

In England and Wales the Regulatory Reform (Fire Safety) Order 2005 places the duty on a 'responsible person' — usually the employer, building owner, landlord or managing agent. That person must arrange a fire risk assessment by a competent person, act on its findings, and keep fire safety equipment maintained and in working order. The assessment is the foundation of every purchasing decision on this page: it identifies the hazards, the people at risk, and the detection, warning, escape-lighting and firefighting equipment the building needs. Buy to satisfy the assessment, not the other way around — over-specifying wastes money, under-specifying is a compliance and safety failure. If you do not have a current assessment, commission one before ordering equipment.

How do I choose the right fire alarm system?

Choose the alarm system by the category your fire risk assessment specifies under BS 5839. For non-domestic buildings, BS 5839-1 defines categories by purpose: M is manual (call points only); L1–L5 protect life with automatic detection (L1 is whole-building coverage, L5 is a designed solution for a specific risk); and P1–P2 protect property. Hotels, HMOs and care settings typically need an L-category system. For domestic and most HMO premises, BS 5839-6 applies instead, using grades A–F and coverage categories LD1–LD3. Once the category is fixed, the number and type of detectors follow — optical/smoke detectors for escape routes and bedrooms, heat detectors for kitchens. Specify the panel, detectors, sounders and manual call points as one compatible system.

What emergency lighting do escape routes need?

Escape routes and key safety points need emergency lighting designed to BS 5266-1 so the building can be evacuated safely if mains power fails. As a rule of thumb, provide illumination at every change of direction, at stairs and exits, at fire alarm call points and firefighting equipment, and outside final exits. Specify the duration your assessment requires — typically three hours for premises with sleeping accommodation such as hotels and HMOs, and one hour may suffice elsewhere. Maintained fittings stay lit at all times (useful in public areas); non-maintained fittings only illuminate on power failure. Self-test or addressable emergency luminaires reduce the burden of the monthly function test and annual full-duration test that BS 5266 requires.

Which fire extinguishers should I provide?

Select extinguishers by the fire classes present in each area, following BS 5306 for selection, siting and maintenance. The classes are A (carbonaceous solids such as paper and wood), B (flammable liquids), C (gases), electrical (live equipment), and F (cooking oils and fats). Water and foam suit Class A offices and corridors; CO2 suits electrical risks and is common beside server rooms and consumer units; wet chemical is required for Class F commercial kitchens. Site extinguishers on escape routes near exits, mount them at the recommended height, and label them clearly. A competent provider should commission them on installation and service them annually — keep the certificates with your fire safety records.

Passive fire protection: fire and smoke seals

Passive fire protection keeps fire and smoke contained so people have time to escape — and a fire door is only as good as its seals. Intumescent fire and smoke seals fit into the door edge or frame and expand under heat to close the gap, while a brush or fin blade controls cold smoke at normal temperatures. Kent Traders stocks Astroflame intumescent fire and smoke seals and fire-stop products for exactly this purpose. Match the seal to the door's fire rating (commonly FD30 for 30 minutes or FD60 for 60 minutes), confirm it carries third-party certification, and fit seals to every fire door including flat entrance doors in HMOs. Pair the seals with certified fire-door hardware and intumescent fire-stopping around service penetrations for a complete compartment.

Certification and ongoing maintenance

Specify certified products and plan maintenance from day one, because compliance is judged on evidence as much as equipment. Look for recognised third-party certification (for example BAFE schemes, LPCB or UKCA/CE marking against the relevant British Standard) rather than self-declared claims. Fire alarms should be tested weekly from a different call point each time and serviced by a competent engineer at the interval BS 5839 recommends; emergency lighting needs a monthly function test and an annual full-duration test; extinguishers need an annual service; and fire doors and their seals should be inspected regularly for damage. Keep a fire logbook recording every test, service and remedial action — it is the documentation an enforcing authority or insurer will ask to see.

Step-by-Step Guide

  1. Obtain or review your fire risk assessment

    Confirm you hold a current assessment by a competent person and note the alarm category, escape-lighting and equipment it specifies.

  2. Specify the alarm system

    Fix the BS 5839 category, then list the panel, detectors (optical vs heat), sounders and call points as one compatible system.

  3. Add emergency lighting and extinguishers

    Plan BS 5266 emergency lighting for every escape route and exit, and select BS 5306 extinguishers by the fire class in each area.

  4. Fit passive fire protection and book maintenance

    Fit certified intumescent fire and smoke seals to every fire door, then set up weekly, monthly and annual testing with a logbook.
