Gas safety checks in TW20: Homeowners vs renters

Homeowners:

You're not legally required to book an annual gas safety check, but it's a good idea to do so, especially if your boiler or appliances haven’t been looked at in a while. If you’re selling your home, some buyers may request proof of recent inspections.

Landlords:

You’re legally required to get a landlord gas safety certificate (CP12) every 12 months for every rental property you own. This covers all fixed gas appliances, pipework, and flues. A copy must be shared with tenants within 28 days of the check.

Renters:

If you’re renting, your landlord is responsible for arranging annual gas safety inspections. If you’re unsure whether your property has been checked, ask your landlord or letting agent for a copy of the latest certificate.
