Gas Safety Certificate Cost | Homeowner & Landlord

Landlord Gas Safety Certificate (CP12) cost

A landlord gas safety check for a typical rental property with one or two gas appliances costs between £50 and £85 including VAT. Properties with more appliances cost slightly more — we quote a fixed price when you book.

Homeowner gas safety check cost

Homeowners don't legally need a certificate, but many request one for peace of mind, before selling or after building work. Prices are similar to landlord certificates — from around £50–£85 depending on appliances.

Combining with a boiler service

Booking a gas safety check at the same time as an annual boiler service is cheaper than two separate visits and keeps everything up to date in one appointment.

Frequently asked questions

Is a gas safety certificate a legal requirement?

For rental properties, yes — landlords must have a valid CP12 renewed every 12 months. For owner-occupied homes it's optional but recommended.

What happens if an appliance fails?

The engineer will explain the defect, make the appliance safe if required, and quote for remedial work. Once fixed, we re-test and issue the certificate.
