If you’re renting out a property in London, gas safety is not optional—it’s a legal requirement. Under UK law, landlords must ensure all gas appliances, fittings, and flues are safe for tenants. Failure to comply can result in heavy penalties, loss of insurance, and more importantly, risk to life.
At Citywide Plumbers, we help London landlords meet their legal gas safety responsibilities with reliable inspections, annual reminders, and same-day certification services.
Key Legal Duties Under the Law
Landlords’ gas safety responsibilities are outlined in the Gas Safety (Installation and Use) Regulations 1998. These duties include:
1. Annual Gas Safety Checks
All gas appliances and flues must be checked once every 12 months by a Gas Safe registered engineer. This includes boilers, cookers, gas fires, and any appliance connected to the gas supply.
2. Issuing a Gas Safety Certificate (CP12)
After inspection, the engineer issues a CP12 Gas Safety Certificate. You must:
-
Provide a copy to existing tenants within 28 days
-
Provide it to new tenants before they move in
-
Keep a copy yourself for at least two years
3. Maintaining Gas Appliances
You’re legally responsible for maintaining all gas appliances and pipework in safe working condition throughout the tenancy—even if a tenant rarely uses a particular appliance.
4. Gas Safe Registered Engineers Only
You must only use engineers registered with the Gas Safe Register to carry out inspections and maintenance. DIY or uncertified work is illegal and dangerous.
What Happens If You Don’t Comply?
Non-compliance is treated very seriously. Penalties include:
-
Fines up to £6,000 per appliance
-
Criminal prosecution or imprisonment in serious cases
-
Invalidation of landlord property insurance
-
Risk of carbon monoxide leaks, fire, or explosion
It’s not just about ticking a legal box—it’s about protecting lives.
