Chris was very friendly and helpful and professional
Jamie attempted to repair our boiler, which in the end turned out to be uneconomical. Install of the new boiler was organised and carried out within a couple of days. On each visit I was given a time slot, e-mailed confirmation on the day, from the office, and had a call from the engineer when leaving his previous job. Easy to do but do many others just leave you wondering when or if they will arrive. Adam in the office was organised and helpful. This is a small business on the up
Gasking were absolutely brilliant, couldn’t be more helpful when a problem was detected and showed great concern in making sure everything was safe when we realised there was a gas leak. Very friendly and helpful on the phone before job was even started which gave a lot of confidence when meeting for the first time. When speaking with your repair in future I will be asking for gasking to come and do anything to do with my plumbing issues. Thanks to Adam and jaimie from gasking it was great to meet you.

Excellent service. Put new Boiler in no trouble very tidy would definitely recommend.
Found company very helpful with small job. Price very competitive and service good.
Trying to modernise my house and finally got round to getting a new boiler. Really impressed by Gas King who were quick to respond and gave me a great price. They were able to start next day which was great because I wanted it done before it starts getting cold again. Engineer was punctual and friendly offering advice on getting smart controls so I can control my heating on my phone. Very professional service and really happy with the work. Will be using Gas King when I go smart and would happily recommend.
