With price of gas these days and although my gas boiler has not missed a beat I felt it was necessary to have the old girl serviced just to give me peace of mind. The AGS technician Ryan turned up on time was very pleasant and helpful in an unpatronising way and carried out a comprehensive service and the price seemed reasonable. Everything was all ok so I can relax for another year. I have used AGS for many years and have never had any complaints but it's always nice to know there's a man called Andy, it's his business and anyone can talk to him. I can't recommend them higher than that.

AGS replaced my internal gas supply pipe which had developed a small leak. The pipe runs under the floor for the whole length of the house so replacing it in situ would have involved ripping up flooring throughout the ground floor, including some expensive wood laminate flooring. AGS devised a solution which involved running the pipe round the skirting board and out of the rear of the property so no damage to the floors. The quote was received within an hour of the engineer leaving and was reasonable. The job itself was done quicker than expected, cleanly and professionally by a cheerful and very polite engineer. Will definitely be using AGS again.

Toilet installation

The fitter from Andy Gas listened to the issues with the fitting of the original toilet which resulted in the cistern cracking. He checked over the new toilet carefully at my request before dismantling anything. He was careful to cover the carpet to keep everything clean and tidy. He checked I was happy with the placing of the toilet with consideration of the impact it would have on the flooring. He discussed how to make good the wall behind the cistern that was now revealed. This was more than I expected as his role was the fitting of the toilet. He was concerned about leaving everything looking good as well as working well.

Work: Replacement boiler, additional radiator, extend gas supply, power flush. I was very impressed with AGS. Jordan and his team worked so hard and were very calming by their no-fuss manner. They left the site clean and on time. They were all very polite and pleasant people to have in my house for 3 days. I most certainly recommend them.

We chose AGS because of the reviews and we were not disappointed. From the initial visit, additional site visits before the work started the logistics, listening to what we wanted, it just gave us confidence from the start. We met Chris our bathroom fitter before he started the work and then he and his apprentice Kieran became part of the furniture for the next 4 weeks. They were courteous, respectful and we felt really comfortable having them about. The quality of work was great, Chris has a real eye for detail and goes that extra mile. Result was we have 2 great new bathrooms. Very happy. We have used AGS before for our boiler servicing and the customer care is excellent, they are coming back to do some additional work for us. I would not hesitate to recommend them.

After a gas leak, which left us with an emergency disconnection and 9 days without use of the boiler (including shower, hot water and central heating) or cooker hob, in the winter and in the middle of a pandemic, AGS came to our rescue. I honestly cannot fault them. Andy scoped and quoted for the job and brought me an electric heater. The young engineers who made the pipes safe were professional, knowledgeable and worked all day on this job, getting the cooker back into place perfectly and clearing up when they had finished. Hot water, central heating and the gas hob are now working perfectly. Everyone wore masks and was careful about social distancing. The invoice was even very slightly under the quote. Highly recommended.

Excellent Covid precautions are taken (mask, shoe covers and distance). Put sheets on the floor where he was working. Arrived within the time frame that I was given. One aspect of the work couldn't be carried out so my invoice was reduced accordingly. The young chap was impressive. He had a good attitude, customer service and demeanour. He was knowledgeable and respectful. He also did a good job and kept me informed on what was going on and when he found a problem he then told me how he was going to resolve it. Well done to that young chap! A good representative of the company. I would definitely recommend Andy Gas Southern Ltd.

Very happy as usual with the annual Vaillant gas boiler service completed. Also had a new G10 Seal fitted. AGS are helpful, friendly, efficient and professional people. Onsite they took care to follow Covid-19 precautions. Boiler installed and serviced since 2009 by AGS. All the work done has always been very good. If only all other companies we have dealt with were up to these standards.

This is the first time I have used Andy Gas but I am used to seeing their vans in the area and I have heard from others locally with good reports of their service. I am pleased to say that they have lived up to my expectations. The fitter was friendly, knowledgeable and efficient. The price seemed fair and the work was completed as per the agreement. I will be using them in future both for routine servicing and problem resolution.
