Fire Alarm Certificates in London: Everything Landlords Need to Stay Compliant
Introduction
If you’re a landlord or property manager in London, keeping your tenants safe isn’t just a responsibility — it’s a legal requirement. One of the key safety obligations under UK law is obtaining a valid Fire Alarm Certificate.
This certificate confirms that your property’s fire alarm system has been professionally inspected, tested, and meets all British Standards (BS5839).
At Anode Electric, our qualified electricians in London provide fire alarm testing, certification, and maintenance to help landlords stay compliant and protect their properties from potential risks and fines.
What Is a Fire Alarm Certificate?
A Fire Alarm Certificate is an official document issued after a qualified electrician inspects and tests your fire alarm system.
It confirms that the installation meets UK safety standards and is in full working condition.
In London, these certificates are commonly required for:
- Rental properties (HMOs, flats, shared accommodations)
- Commercial premises (shops, offices, schools)
- New builds and renovated properties
For complete electrical safety compliance, landlords should also obtain an EICR – Electrical Safety Certificate.

Legal Requirements for Landlords in London
Under the Regulatory Reform (Fire Safety) Order 2005 and The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022, landlords must:
- Install and maintain working fire alarms on every storey
- Ensure alarms are interconnected in HMOs
- Conduct regular testing and inspections
- Hold valid certification issued by a competent electrician
Failure to comply can result in fines up to £5,000 or more for serious breaches.
