Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 23 years on the register also points to an established business rather than a brand-new one.

Was recommended these guys a few years ago for a boiler, can't fault them in any way. Turn up today to service the boiler but had to fix the zone valve that failed 2 days ago. Already booked to come back and do the service.

Verified by CheckatradeAnother great boiler service
I have been using Andy Gas to service my boiler for years. They are always efficient and helpful, that’s everyone in the admin team and my regular engineer Sam who is experienced and knowledgeable, a very clean and tidy worker. He also takes care to ensure I understand what I need to know about my boiler. Good value for the excellent work they do.

Verified by CheckatradeFixing a leak & new shower install
Repeat customer, Andy Gas were great they helped to install new and additional valves to address the leak in my kitchen and also replaced my shower in the bathroom after this was dripping constantly and quite dated. Respectful engineers, arrive when they say they will and peace of mind the job will be done properly. Definitely recommended them.
Can't recommend this company enough. A quick response to my initial email requesting an appointment. Very helpful. On the day Connor and Harry turned up on time and were very professional and polite. They explained everything in detail and did a great job. This is the second time I have used this company and will definitely be using them again in the future.

Gas work is restricted by law to Gas Safe registered engineers. If they'll touch a boiler or any gas appliance, confirm they're currently on the register before you hire - it's free and takes a minute.
Check the Gas Safe RegisterBy 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.
