A tenant turns on the heating on a cold winter morning. The boiler starts, but something is wrong. Carbon monoxide fills the property. The tenant becomes ill. You're called to investigate. The fire service finds your boiler hasn't been serviced in three years. Now you're facing a £6,000 fine, criminal charges, and a tenant with a serious injury claim.
This scenario happens to landlords every year. Yet it's completely preventable with proper gas safety compliance.
Gas safety certificates are mandatory for all rental properties with gas appliances. Yet many landlords don't understand the requirements, leading to violations and fines. As a landlord, you are legally responsible for ensuring gas safety in your rental properties.
