Highlights
"Jamie was clearly very experienced, very professional and very friendly. He followed through with everything he said he would. Was punctual and cleaned up after himself every day."
"Jamie contacted the tenant for access and carried out the check. He reported back to me on the condition of the boiler and what might need to be done next year. A very prompt, efficient & smooth procedure, and a fair cost."
"Jamie installed a new boiler, pipework and radiators as part of a house renovation 3 years ago, can't fault his work to be honest. Had an issue with the boiler which turned out to be a warranty issue. The engineer from Valliant said it made a nice change to see an installation where the installer clearly knew what they were doing and was very complimentary about his work."

Gas work is restricted by law to Gas Safe registered engineers. If they'll touch a boiler or any gas appliance, confirm they're currently on the register before you hire - it's free and takes a minute.

Smart checks
Before you hire a gas engineer
By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
