Highlights
"Jack has been great — super friendly, turned up on time, and did a solid job. Everything sorted with no hassle. Would definitely recommend."
"Jack did my annual boiler service. He was very professional, reliable and even explained what the parts/functions of my boiler did. Will defo use again!"
"Jack is friendly, courteous and nice to talk to. He had to troubleshoot the reason why my boiler pressure was not going down, which required ruling out various causes before eventually coming to the final conclusion. He also readjusted a boiler pipe for me so that a board can cover the pipework. He visited the property 3 times in total. I would recommend him."

Smart checks
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.
