Fire Alarm
Installation

The regulations behind every fire alarm installation

Two separate sets of rules sit behind a domestic fire alarm installation in England. The first is the Smoke and Carbon Monoxide Alarm (England) Regulations 2015, amended with effect from 1 October 2022, which set the bare minimum a landlord has to provide. The second is BS 5839-6, the British Standard code of practice for the design, installation, commissioning and maintenance of fire detection and fire alarm systems in domestic premises. That standard is what a council, an insurer or an HMO licensing officer will measure your system against.

The Regulations themselves are short. At least one smoke alarm must be fitted on every storey of the property on which there is a room used as living accommodation, and a carbon monoxide alarm must be fitted in any room used as living accommodation that contains a fixed combustion appliance, gas cookers excepted. Alarms have to be tested and confirmed working on the first day of a new tenancy, and repaired or replaced once a tenant reports a fault.

The government publishes a plain-English explanation of those duties for landlords and tenants as guidance on GOV.UK. It is worth ten minutes of any landlord’s time before a first system goes in, because it settles most arguments about who is responsible for what.

Where the standard goes further than the minimum

Meeting the 2015 Regulations is not the same as meeting BS 5839-6. The Regulations ask for an alarm per storey and say nothing about interlinking, grade or category. The standard sets out how the system should actually be designed: which grade of equipment is appropriate, which rooms get a detector, how loud the alarm has to be at the bedhead of a sleeping occupant, and how the finished system is commissioned and recorded.

In practice most London letting agents, licensing teams and insurers write the standard into their own requirements. A compliant system in a rented property is therefore normally a Grade D interlinked installation rather than a handful of standalone battery alarms bought from a DIY shed.

Where a building has common parts — a converted house in flats, a purpose-built block, a shop with a flat above — the Regulatory Reform (Fire Safety) Order 2005 also applies to those shared areas. The responsible person must hold a current fire risk assessment, and the detection system in the common parts is designed around whatever that assessment concludes.

Enforcement, penalties and the evidence you keep

Local housing authorities enforce the 2015 Regulations. Where a council is satisfied that a landlord has breached a duty it serves a remedial notice, and where that notice is not complied with it may arrange the work itself and impose a penalty charge of up to £5,000. HMO licence breaches are dealt with separately under the Housing Act 2004 and carry heavier consequences, up to prosecution or a civil penalty.

Whatever the enforcement route, the evidence a landlord needs is the same: a commissioning certificate naming the standard the system was installed to, the grade and category achieved, the position of every detector, and the date of the work. That document is issued at the end of every job we carry out, and it is the piece of paper a licensing officer asks for first.

Testing, servicing and the ten-year clock

A detection system is not a fit-and-forget purchase. BS 5839-6 expects a weekly test of the system by the occupier — press the test button on one detector, confirm every other device sounds — and a periodic inspection by a competent person. In a rented property the landlord provides the alarms and keeps them working; the tenant presses the button.

• Weekly: occupier test of one device, checking that the interlink carries to every other alarm in the property.
• Start of every tenancy: the landlord tests and records that all alarms are working on the first day of the term. This is an explicit duty under the 2015 Regulations.
• Annually: a competent-person check of the detectors, the interlink, the supply and the standby batteries, documented for the licence file.
• Every ten years: replacement of the detector heads. Sensors drift with age, and a sealed lithium cell reaches the end of its service life at roughly the same point.

Faults reported by a tenant have to be dealt with, not diarised. If a device is chirping, discoloured, sounding without cause or simply past its replacement date printed on the casing, it needs swapping, and we can usually do that on the same visit as a service.

Why landlords book their fire alarm installation with us

We are NICEIC and NAPIT registered electrical contractors working across all 32 London boroughs, and detection work is a daily job rather than an occasional sideline. Every system is designed to a grade and category before anyone picks up a drill, wired in neat surface trunking, commissioned properly and handed over with a BS 5839 installation and commissioning certificate the same day.

Because we are electricians first, we can also deal with what the survey turns up. If the lighting circuit intended to feed the alarms is not fit to carry them, or the consumer unit has no spare way, we will tell you on site and quote for the remedial work rather than leaving you to find a second contractor. An EICR certificate on the same visit is often the cheapest way to find that out before the job starts.

Bundle the visit with your other compliance work and there is one appointment, one engineer and one set of paperwork. Book your fire alarm installation online and pick a slot that suits the tenants, or call the office and we will scope it with you over the phone.
