I strongly recommend Gasman.
Customer Service
I Initially asked for a quote for compliant smoke/heat alarms along with some relatively minor electrical bits and pieces. They were very quick (and patient) in providing the quote and in dealing with my multiple queries. We put the alarms on hold simply as my wife comes to terms with having a flashing light in our living room but the engineer who came to do the bits and pieces was excellent. He was clearly good at what he was doing and was happy to offer a view and was quick and left everything clean and tidy. The price was reasonable.

Customer Service
Gas engineers turned up on time, phoning me if they had been delayed. New boiler and four radiators were fitted. All the guys were polite and professional. I dealt mainly with Ceiran. He was very patient and spent time explaining things to me. He did not try to hurry me in any way. He telephoned me a couple of times to update me on progress, and each day he spent time explaining what had been done, and next steps. What stands out to me making this company different from others I have dealt with was the attention to detail and having respect for my home. Ceiran was courteous in moving his van from my driveway when he knew I was coming home. Two of my cupboards had to be emptied in my absence and my belongings were all neatly stacked - this showed me I was dealing with someone who has high standards. After a detailed explanation, Ceiran said if there was anything I was unsure of to phone the office or I could call him. He was very professional, but friendly and approachable too. I will recommend this company to others.

Excellent work
Customer Service
Excellent service from this company that fitted a new boiler and 6 radiators to my property. A terrific experience from start to finish everyone I dealt with, either, in the office or the heating engineers who carried out the installation, were friendly and helpful. Great advice given on choosing the correct boiler and the installation was carried out to a high standard and any mess was quickly tidied up. Work was carried out on time and at a very reasonable price. Nice to find a team of people who take pride in their work. I will certainly use them in the future.

Quick, professional company with family values
Customer Service
In spite of a major road closure the installation team arrived at the agreed time. The detour was over 50 miles. The engineers were very professional and considerate, explaining the various options regarding positioning of equipment and giving guidance to the best solution. The company prides itself on quality work and old fashioned family values. At all levels the responses were professional, clear and timely. It’s a pity that all companies could not operate at this level.

If Carling did boiler repairs...
Customer Service
After my previous experience with an appalling company who, after 6 visits had failed to fire my boiler and declared it full of sludge, it was like a breath of fresh air to find this company. Michael arrived when he said he would, serviced and fixed my boiler quickly and cheaply and it's been fine since. Job done.
