Dan fitted a new radiator in my bathroom he went over and above to source the right size for me. Absolutely a good tradesman and done the job perfectly. Highly recommend.

I would just like to say how helpful, professional and courteous your plumber was today whilst fitting a whole house water and drinking filter system. He was polite and respectful of our property and took his time to ensure this new water filter system was installed to the manufacturer guidelines. I’m 68 years old and over my life have encountered many different trades individuals. Your Dan is an exception, he is most diligent, meticulous and passionate with his work. I am so pleased I waited for you rather than just go for the next available plumber. Your Dan is without doubt a great asset to AJS.

I just wanted to let you know how pleased we are with everything. The lads are a pleasure to have in our home.  All of them are pleasant, courteous and helpful. They work hard, clearly know their jobs and respect our home, putting down protective coverings and clearing up after them. We are also very happy with the work.  The boiler is very quiet and will require very little intervention from me. The radiators look great and my son is particularly pleased with the anthracite ones in his private domain.

AJS installed and have serviced my boiler for more than five years. As a company they are professional, reliable and competent. As individual members of staff they are polite, friendly and helpful. I would not go elsewhere.

My new Vaillant boiler was installed this week by AJS Gas and Heating Services Ltd and I found it to be an extremely easy process. The workmen who came were very pleasant and polite and carried out the work seamlessly from beginning to end with very little mess. I have a lovely new boiler which works much more efficiently than my old one did.
