Highlights
"Outstanding Work and Professional Service! Mehdi first came to our home about a year ago to install an air conditioning unit in our living room, and he did such a fantastic job that we didn’t hesitate to call him back for more work. This time, he installed additional units in the hallway and our master bedroom. As before, the job was completed right on schedule, and the quality of the finish was excellent. Both my wife and I are really impressed—the installations look great and blend in beautifully with our home. Thank you, Mehdi, for your reliability, professionalism, and high-quality work"

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.
