Highlights
"Excellent service would highly recommend"
"Great service. From the moment I spoke to the team in the office to seeing the engineer. You were recommended by a neighbour and I will definitely use your team in the future for my boiler service. Thank you all so much"
"LPG Boiler was installed by John Williams Heating Services in 2019 and they’ve been the ones to carry out the annual service on it ever since. Every one who has ever carried out the work has been courteous, considerate of my property, very thorough in respect of the work being carried out and even offered guidance on how to get the best from the boiler. I can honestly say that every engineer who’s been to my home has been extremely professional and a credit to the company. I would highly recommend this company and I personally, wouldn’t choose to go anywhere else,"

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.
