As many reviewers said before, I found Kas from Gas+ a reliable professional - good grasp of details, offering excellent service at v reasonable costs. Remarkably no-fuss, efficient service delivery of replacing towel rail radiator, and on-the-spot bolier service. Happy to recommend to anyone who’s looking for a 5* plumbing /Radiators/ Bolier service professional.

Absolutely amazing work done by Pipe Wizards Ltd on the refit of my guest en-suite, even with having to make a shower door fit unevenly built walls!!! Totally professional from start to finish, absolutely great price for everything they did, punctual, professional and a pleasure to have here. Won’t have anyone else now for my plumbing needs and have already recommended them to many others too. Don’t waste time and money going anywhere else, Pipe Wizards are simply the best!!

I phoned Gas+ because my boiler was not heating my central heating. Neither my hot water. Kas came out with in 2 hours. He checked everything out and found my pump to be not working. My pump was found to be obsolete so Kas removed it, cleaned it all out and replaced it. Saving me loads of money on a brand new one. My heating works perfect now because of the extra attention that he provided to get my heating working again. I will definitely be using Gas+ from now on.

I was searching for a new gas boiler in April 2025 and got several quotes from different people. Kas not only gave the best quote and the best resolution for our situation, but he also came across as being the most down to earth and trustworthy. I was not disappointed. Kas and his partner Nick worked hard to fit our new boiler. They completed the work well within the predicted timescale. I was very pleased with their work and did not hesitate to contact them again more recently when I needed a new radiator fitted. This time Nick arrived on time and did a really good job. I would recommend.

I found Kas (Gas+) on checkatrade and when other businesses failed to respond or return my calls. Kas got back to me straight away. Kas gave me invaluable advice regarding my underfloor heating, probably saving me £thousands. He expertly examined my underfloor heating, gave me a full understanding of how it operated and got it working again on the first visit. He then returned with all the necessary parts and services my boiler (which had been neglected for years). Kas was extremely responsive, polite, honest, dependable, knowledgable, professional and very cost effective. I will certainly use Gas+ again for any gas, heating or plumbing issues in the future. 5* service and I cannot recommend him highly enough.

Great experience with Gas+. Communication with Kas was quick and straightforward, and everything was arranged easily. Nikijs installed a new kitchen tap with Water2 filter, replaced the under-sink pipework with flexi hoses, and fitted a new outdoor tap. He was efficient, tidy and the work was done to a high standard. Really pleased with the result and happy to recommend Gas+.

Kas did an exceptional job for us today. He arrived on time and very smartly dressed. We had booked him for a boiler service but he identified several other issue as well, which he put right without a fuss. He worked quickly and left no mess. Absolutely fantastic. We will be using him from now on....
