Fire Detection Systems York: Smoke & CO Alarms (2026)

We design and install fire detection systems for York rental property, HMOs and owner-occupier homes. Compliant with the 2022 Regulations, specified to BS 5839-6 Grade D2 LD2 as standard, mains-wired and interlinked so a fire anywhere in the property triggers every alarm.

The 2022 Regulations in plain English

The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 apply to every private rented and social rented property in England ^[1]. The legal minimum:

• At least one smoke alarm on every storey where a living space exists.
• A CO alarm in every room used as living accommodation that contains a fixed combustion appliance (other than a gas cooker).
• Landlords must ensure alarms are in working order at the start of each new tenancy.
• Faulty alarms must be repaired or replaced as soon as reasonably practicable when reported.

Grade D vs Grade F, LD1 vs LD2 vs LD3

Why the difference matters for landlords

The 2022 Regulations set the minimum to avoid a fine. BS 5839-6 LD2 exists because it actually protects the property and the tenants.

• What Grade F LD3 means in a kitchen fire: a battery alarm in the hallway triggers once smoke reaches it. By then the kitchen is well into the fire. The kitchen needs stripping, adjacent rooms have smoke and heat damage, the tenant is displaced, your rental income stops.
• What Grade D2 LD2 means in the same scenario: a mains-wired heat alarm in the kitchen triggers at the first sign of abnormal heat. Every interlinked alarm sounds. Tenant out in the first minute or two. Fire service arrives to a contained incident. Repair time is days, not months.
• Civil liability: a landlord whose tenant suffers injury or property damage in a fire can face civil claims. We met the legal minimum is a defence. We installed what BS 5839-6 recommends for rental property is a much stronger one.
• Insurance: some insurance policies specify mains-wired alarms as a condition. Check yours. The premium saving can recover the upgrade cost inside a few years.

What I install

• Optical smoke detectors. Detect slow-burning, smouldering fires (upholstery, bedding, electrical). Correct for living rooms, hallways, bedrooms.
• Heat detectors. Trigger on abnormal temperature rise. Correct for kitchens, where cooking fumes would false-trigger a smoke detector.
• CO alarms. Required in every room with a fixed combustion appliance under the 2022 Regulations. Combined smoke/CO units available where a single device in a room covers both.
• Mains interlinked wiring. Alarms wired to the mains (usually off the lighting circuit) and interlinked. Triggering one triggers all. Battery backup for power cuts.
• Wireless RF interlinked. Where mains wiring is impractical, 10-year sealed-battery alarms with RF interlinking. Grade F1 instead of Grade D2, still a significant upgrade on standalone battery alarms.

Combined with EICR and CO compliance

For landlords the most efficient approach is to address the EICR, the fire detection system, and CO alarm compliance in a single visit. I carry out the EICR, check and document the existing alarm system, install any additional alarms, and confirm overall compliance with the 2022 Regulations and BS 5839-6 all on the same day.

You get a single paperwork pack: EICR, fire detection design and installation certificate, CO alarm record, and a summary for your compliance file, ready to hand to your tenant or local authority. See the landlord hub for the full electrical compliance picture, the smoke and CO alarm installation page for the 2022 Regulations baseline, and the smoke and CO detector regulations blog for the plain-English summary.

A note on cost

I scope every install on the property: storey count, existing wiring, whether plaster access allows mains-wired alarms, and whether the EICR is being done alongside. Get in touch with the property type and address and I'll come back with a written estimate before I book. Book a survey.
