Public evidence profile
How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Use this as a reason to call them first, not a guarantee they can attend now. Confirm availability, timing, and call-out terms directly before you rely on it.

Andy Gas Southern Limited is linked to a Companies House entry. This shows the business registration, not evidence of workmanship or service quality.
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.

Professional, efficient and polite
Easy to contact and answered enquiry quickly Pleased with the work carried out
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.
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.
A reminder from Andy Gas when boiler service was due, booked an appointment, engineer turned up at date and time stated, Excellent job,
Despite many unforseen setbacks on heating and water alterations and upgrades, got the jobs done on time by bringing in a larger team. Professional and polite throughout. Used them many times and never had a problem.

We have used Andy Gas for our servicing for several years as well as any work that has been needed for our boiler and heating. They have been fantastic every time. Always punctual, professional and friendly with great communication- highly recommended!
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.
Great professional, yet friendly, boiler service from Connor and Fred. Got on with the job with a minimum of disruption. AGS and their staff are outstanding.
