Highlights
"Came out when said, explaining everything as he fixed the issues, couldn’t fault the service."
"Gentleman appeared in time and fitted the room programmer within the time mentioned. He also gave advice on future replacement of thermostat and install latest technology."
"Not many gas engineers specify themselves to provide gas hob installation. Luckily Big Boss is one of those who is accessible and replies promptly. The engineer arrived on the next day even we just connected at the evening the day before. With some special conditions on my worktops and setting, the engineer managed to install and hob quickly and professionally! Great services and cannot recommend more!"

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.
