Landlord gas safety certificates
Every rented property with gas appliances needs a CP12 gas safety record each year, and it is the landlord's responsibility to keep it current. We check the boiler, any gas fires and the pipework, then issue the certificate the same day by email.
We book around your tenants, contact them directly if you would rather we did, and can put the property on a yearly reminder so the certificate never lapses.

What do you need doing?
We will get back to you the same day.
Common questions
Most full systems take two to four days depending on the size of the property and how much pipework needs running. We give you a firm timescale with the quote and stick to it.
If radiators are cold at the bottom, the system is noisy or the water runs black when you bleed it, there is sludge in the system and a power flush will help. We check the system first and tell you honestly whether it is worth doing.
Yes. We move radiators for kitchen and bathroom refits, decorating and layout changes, re-running the pipework and making good as we go.
Yes. We fit and set up Hive, Nest, Tado and standard programmable thermostats, and show you how to use them before we leave.
No. Quotes and call outs are free, with no obligation to book the work.
