Can’t recommend enough. Used a few times and have always been impressed. Punctual, professional, neat and tidy and fairly priced. Will always be my first choice now.

Kirk H., Excellent Service
My heating and electrics developed a fault which lead to my property being without heating and an electrical circuit. I then had a gas engineer sent out by my insurance company who was unable to find the problem and after 2 hours he explained that I needed an electrician. My insurance then sent two electrical engineers out who proceeded to lift floor boards and dismantle sockets over two days as they were trying to locate the fault. They were unable to do so and told me I needed a gas engineer again… A few painstaking days had passed with this issue… My insurance then sent an engineer named Kevin from McMahon Gas and Electrical who is a gas and electrical engineer. Kevin diagnosed the fault(s) less than an hour into entering in my property. He was then able to source the replacement parts and repair the faults within two hours. I will definitely be using McMahon Gas and Electric for any future property maintenance issues and am thankful that my insurance finally got it done.
