Highlights
"we had a great experience with this company. the engineer was prompt, friendly and thorough and kept me informed throughout, even navigating an anxious dog who had to be moved between rooms so he could get to every radiator! the invoice amount was adhered to and I had a call before the engineer arrived to let me know he was on the way. all in all great service and would recommend"
"Absolutely superb! They called, arrived on time, did what they said and all with such professionalism and pleasantness. I can only highly recommend them!"
"The company did a good job waiting until all the radiators had been received from their suppliers, so that there would be no interruptions during installation activities. However, only about 5 hours of work was done each day, due to child care needs; this was not advised in advance. This meant that the installation activities went on for 4 days, leaving the house colder for 4 days. There were some problems noticed subsequently with a leak on one radiator, and the boiler cutting out at the boiler thermostat max setting; which had not happened previously. Now more works need to be done."

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.
