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.

Annual boiler service. Andy Gas are polite and efficient arranging appointments. I was late getting back for my appointment, the engineer was happy to wait (10 mins) for me to return. Very friendly and efficient. Explained everything they had done. Clean and tidy, no mess at all. Checked boiler was off before leaving as a very hot day when they serviced it. Excellent reliable company.

Ryan came to service our Ideal boiler. Polite, professional and courteous. Moved straight into performing the service on the boiler. Completed an inspection form as he went and also checked all the radiators at the end and bled. Good clean worker and will be using them again from now on. Super happy to have a trusted company after my last plumber retired!

Andy Gas usually does an excellent job of looking after our gas central heating system. This was the first time they had done any bathroom work for us, which involved replacing a dodgy loo seat and dealing with leaking problems in both our two showers. All completed on time to an excellent standard. We highly recommend them.

I can't fault Andy Gas Southern, from booking an appointment to completion of work. The engineers are professional, polite, very knowledgeable and take time to explain things. They do the job thoroughly and I have every faith in them. As a bonus, their charges are reasonable, which really helps!

Andy Gas Southern were identified using Which? Trusted Traders. The meeting to discuss the replacement of the gas boiler was detailed and explored all the different options available. It was agreed for a replacement gas boiler and replacement of pipework from the gas meter to the property. The work was undertaken by a team of four who worked consistently and problem-solved the difficulties of the job. The team were very polite, professional and were excellent in their communications to me as a slightly anxious customer. The work was completed in a timely way and to a very high standard. The property was returned to its original condition and very tidy. I highly recommend Andy Gas Southern and look forward to booking them next time. Thank you so much!
