Smoke and CO Alarm Regulations for Landlords

Since October 2022, all landlords in England must comply with the Smoke and Carbon Monoxide Alarm (Amendment) Regulations. Here is what the law requires.

Smoke Alarms on Every Floor

You must have at least one working smoke alarm on every storey of your property where there is living accommodation. This applies to both private and social landlords, and alarms must be in working order at the start of each new tenancy.

CO Alarms in Every Fuel-Burning Room

A carbon monoxide alarm must be fitted in any room containing a fixed combustion appliance, such as a gas boiler, wood-burning stove, or open fire. Gas cookers are currently excluded in England, but not in Wales.

Penalties for Non-Compliance

Landlords who fail to comply can be fined up to £5,000 by the local authority. If a tenant reports a faulty or missing alarm, you are legally required to repair or replace it as soon as reasonably possible.

Why You Need Smoke and CO Alarms

Landlord Legal Requirement

Since October 2022, all rented properties in England must have working smoke alarms on every floor and CO alarms in rooms with fuel-burning appliances. Non-compliance carries fines of up to £5,000.

Protect Against CO Poisoning

Carbon monoxide is odourless and invisible. Around 60 people die from CO poisoning in the UK each year. A correctly placed CO alarm gives early warning and saves lives.

Home Safety and Insurance

Working smoke and CO alarms reduce fire risk and may be required by your home insurance provider. Upgrading to interlinked alarms means every alarm sounds when one detects danger.

Types of Alarms We Install

We supply and fit a full range of smoke and carbon monoxide alarms to suit every property. All alarms meet current British Standards.

Optical Smoke Alarms

Best for detecting slow-burning fires from furnishings and overheated wiring. Suitable for hallways, landings, and living areas. Required on every storey of rented properties.

Heat Alarms

Designed for kitchens and garages where steam or cooking fumes would trigger a smoke alarm. Heat alarms respond to rapid temperature rise rather than smoke particles.

Carbon Monoxide Alarms

Essential in any room containing a gas boiler, wood burner, open fire, or other fuel-burning appliance. A legal requirement in all rented properties since 2022.

Interlinked Alarm Systems

When one alarm detects danger, every alarm in the system sounds. Interlinked alarms provide whole-property coverage and are the recommended standard for HMOs and larger homes.

FAQs

Common questions about smoke alarm and CO detector installation, regulations, and what to expect.

Interlinked alarms are not a legal requirement in all properties, but they are strongly recommended. When one alarm sounds, all connected alarms sound throughout the property. This is especially important in HMOs, larger homes, and properties with multiple floors. Scottish regulations require interlinked alarms in all homes.
Smoke alarms should be replaced every 10 years, and CO alarms every 5 to 7 years depending on the manufacturer. Landlords must also check that all alarms are working at the start of each new tenancy. We can set up a reminder service so you never miss a replacement date.
Smoke alarms should be fitted on the ceiling of every storey, ideally in hallways and landings. CO alarms should be placed in any room containing a fuel-burning appliance such as a boiler, fire, or wood burner. We position every alarm according to manufacturer guidelines and current British Standards.
Yes. After every installation, we issue a certificate confirming that your smoke and CO alarms have been installed and tested in accordance with current UK regulations. Landlords can use this as evidence of compliance with the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022.
The cost depends on the number of alarms needed and the size of your property. For a standard residential property, expect to pay between £150 and £400 including alarms, fitting, testing, and a compliance certificate. We provide a fixed-price quote with no hidden extras before any work begins.
