We provide professional carbon monoxide alarm installation starting from just £45, helping landlords, property managers, and homeowners meet their legal responsibilities and protect lives.
Protect Lives with Compliant Carbon Monoxide Alarm Installation
Carbon monoxide (CO) is an odourless, colourless, and highly toxic gas produced by faulty gas appliances such as boilers, cookers, and heaters. Without a working CO alarm, it’s impossible to detect and exposure can be fatal.
That’s why UK law now requires carbon monoxide alarms to be fitted in all rental properties with gas appliances or solid fuel-burning systems, including those in HMOs, flats, and residential lettings. Our qualified engineers ensure every alarm is installed correctly and positioned in compliance with the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022, helping you avoid fines, enforcement notices, and — most importantly — prevent tragedy.
We install tamper-proof, long-life detectors in key areas, provide installation certificates for your records, and offer same-day service across London and surrounding regions. For landlords, housing associations, and letting agents, we also offer bulk discounts for multi-property portfolios.

Protecting Lives Through Early Detection
Carbon monoxide (CO) is a silent killer. It is colourless, odourless, and tasteless, making it virtually undetectable without the right alarm. Faulty boilers, gas cookers, fires, or poorly ventilated fuel-burning appliances can release this toxic gas, posing a serious risk to lives. Early symptoms of CO poisoning, such as headaches, fatigue, and dizziness, are often mistaken for common illnesses, allowing exposure to go unnoticed until it becomes life-threatening.
At HSE Property Checks, we help you prevent this danger with professional carbon monoxide detector installation that meets current legislation and protects your home or rental property. Our alarms can save lives, offering 24/7 monitoring, fast activation during a leak, and peace of mind for occupants.
