Professionally designed and installed fire alarm systems for homes, HMOs, offices, and commercial premises across Essex and East London. KLIC ELECTRICAL installs Grade D and Grade A systems to BS 5839 — fully certified.
A properly designed and installed fire alarm system is one of the most important safety investments in any building — giving occupants the earliest possible warning and the maximum time to evacuate safely. The specification of the system must match the building type, occupancy, and risk — a domestic Grade D system is appropriate for most homes, while commercial premises and HMOs require Grade A addressable or conventional systems.
KLIC ELECTRICAL designs and installs fire alarm systems for all property types across Essex and East London — from Grade D interlinked mains alarms for rental properties to full Grade A conventional and addressable panel systems for offices, warehouses, and commercial premises. All installations are completed to BS 5839 Parts 1 and 6, with commissioning certificates issued on completion.
We assess your property, occupancy, and risk level to specify the correct system grade, detector types, and coverage — ensuring BS 5839 compliance from the outset.
Fire-rated cable installed to all detection and alarm devices — routed to minimise disruption to existing décor and concealed where possible.
Smoke detectors, heat detectors, and multi-sensor devices installed in the correct locations per BS 5839 coverage areas — ensuring the fastest possible detection in each zone.
Grade A conventional or addressable panel, or Grade D control unit, installed and configured — with zone mapping for larger premises and visual/audible alarm outputs.
Full commissioning of the installed system — testing every detector and manual call point, verifying alarm outputs, and confirming correct panel operation throughout.
Installation and commissioning certificate issued on completion — including the as-installed zone plan, device schedule, and test results, as required by BS 5839.
An incorrectly designed or installed fire alarm system may fail when it matters most — with potentially fatal consequences.
Commercial premises are subject to the Regulatory Reform (Fire Safety) Order 2005, requiring a suitable fire detection and alarm system. New residential developments must comply with Building Regulations Part B. Both require compliant, certified installations.
HMO licensing conditions specify minimum fire detection requirements — typically Grade A or D systems with specific detector types in each room type. Failure to meet these conditions risks licence revocation.
Buildings and contents insurance policies for commercial premises typically specify that a fire alarm system must be installed and maintained to BS 5839. Our commissioning certificate provides the documented compliance evidence insurers require.

Grade A vs Grade D — Which Do You Need?
Grade D systems use mains-powered interlinked smoke and heat alarms — appropriate for most homes and smaller rental properties. Grade A systems use a central control panel with dedicated cabling — required for most commercial premises, HMOs with more than 3 storeys, and complex residential developments. We advise on the correct grade for your specific property and occupancy.

Common questions about fire alarm installation in Essex and East London.
A Grade D system uses mains-powered interlinked smoke and heat alarms (the type you commonly see in domestic ceilings) with battery backup. Appropriate for most houses and smaller rental properties. A Grade A system uses a central fire alarm control panel with dedicated fire-rated cabling and addressable or conventional detectors — required for most commercial premises, HMOs above a certain size, and complex developments.
A Grade D domestic interlinked system typically costs £400–£900 depending on the number of devices and cable run distance. Grade A commercial systems are priced on a project basis depending on floor area, number of zones, and panel type. We provide fixed written quotes after a free site survey.
Under BS 5839 Part 6, smoke detectors should be installed in every circulation area (hallways, landings) on each storey. Heat detectors are typically installed in kitchens (where cooking fumes would cause nuisance activations from smoke detectors). Bedrooms require smoke detectors for sleeping risk. The exact specification depends on the property type and risk assessment — we advise on this during the site survey.
Yes — HMO licensing conditions in England specify minimum fire detection requirements. For most HMOs this means a Grade A or Grade D system with smoke detectors in each bedroom, the kitchen, and all circulation areas, plus a heat detector in the kitchen. The exact requirement varies by local authority — we are experienced with Essex and East London council HMO conditions.
BS 5839 Part 1 recommends that installed fire alarm systems receive a formal inspection and test at least every 6 months (Grade A systems) or annually (Grade D systems). We provide maintenance contracts covering periodic inspection, testing of all devices and the panel, and a service certificate on completion.
Yes — we assess existing systems and carry out upgrades, expansions, and full replacements as required. Where an existing system is obsolete, obsolete panel types are end-of-life, or additional coverage is required to meet updated HMO or commercial licensing conditions, we design and install the replacement system and issue a new commissioning certificate.
