Thank you very much for completing the work on our boiler. We were very pleased with the installation. Everything was done promptly and efficiently and I would not hesitate to recommend you to other customers in the future.

I was very sceptical when my tenant advised me about this scheme. However after a bit of checking out I went ahead. She was very happy with how the work was completed and has already said he heating is more efficient. I would recommend anyone to try this company and go for it.

Couldn't recommend these guys enough. Is great to see that there are workmen who still take pride in their work. Were really accommodating when I changed my mind about some of t he fittings and was no bother at all. Equally the same when I asked them to do additional bits and pieces. Really really pleased with them. Would not hesitate in using them again.

I selected JSJ Gas because when the gas fitter came to give me a quote he was the most professional, clear and informative. I was very pleased with the way the work was c arried out, extremely efficiently and I would certainly recommend.
- Ms J. Brettingham, Bournemouth
Arrived on time and completed the work to a high standard, removing the old boiler and installing a new energy-efficient one with thermostat. The only issue that was encountered was that the thermostat did not work with the new boiler (due to incompatibility) and NOT the fault of the engineer. It was changed for a more advanced model at no extra charge. The engineer was very polite and friendly and all the work was completed within the one day. My only disappointment was that the kitchen was not cleaned properly after the work had been finished. However, I would not hesitate to recommend this company to people in the future..

Left them to it. Stewart and Jim did an excellent job with no fuss. They worked so hard, twisting their bodies into tight corners, shifting heavy furniture and putting it back. After they left there was no mess or cosmetic damage. Their relaxed and friendly manner did not disguise the fact that these men are grafter and great professionals..
- Ms Gaudion,London
Excellent, great to find local company on under floor heating, polite, efficient and reliable.
- Mrs Davies,Wimborne
Stuart and James arrived at the time. They stated working from the moment they reached our front door. At all times we were kept informed of what was happening and asked if there where any difficult areas to be dealt with (routing of pipes, etc). All work was completed on time and to budget and our central heating is now working better than ever after it was set up by Stuart and James. Sabrina was also most helpful on the phone and was able to answer any questions we had on the initial quote with ease. Good reliable team all round. Highly recommended.
- Mr B Venter, Southampton
Jim came to service our boiler and generally check up on our solar hot water system, which he installed earlier this year. The solar panels and all accessories are working perfectly and we do not regret for one minute installing it all. Jim serviced the boiler efficiently and was very patient with any questions and tales we had regarding our new system. Over all we had no problems since the installation and the yearly service was done professionally and efficiently, as always.
