Allstar Systems (Norwich) Ltd - Norwich

Had a major problem with our hot water system that William sorted and replaced in a very timely manner. Keeping us in the loop on time scales for replacement parts along with how the work schedule would be completed. Being without hot water over the Christmas period seemed like a real possibility but Allstar made sure we were sorted professionally and promptly.

Installation looks a big improvement on the old system as well - first rate service all round.

Two weeks before Christmas and our unvented mains hot water tank died.
Allstar visited within a couple of days and not only deemed it terminal but that it had been installed incorrectly, illegally, by the original plumber.
Within a week they had sourced a new tank and installed in line with the building regulations.
One cannot ask for better service than that.

If you want, or have got an unvented mains hot water tank, ("Megaflow"), these are your guys. They have the essential additional qualifications over and above the usual "Gas Safe" one.

Really impressed and reassured by Allstar Systems (Norwich) LTD.
We had a dangerous issue with our oil fired boiled and William came out as an emergency. He ensured the safety of our tenants and had a new boiler installed ASAP with no disruption to our guests. He also talked us through some basic procedures and was very quick to get back to us when needed.
Very reliable and have recommended to other landlords who prioritise safety.

Hopefully we won't need them to attend again. But if we do we know we'll be in safe hands.

Thank you!

Having brought a house with a boiler that was extremely old and not working - Allstar was very quick to get back to me with a quote and when they can install. I was extremely happy that they could install a couple of days later as I didnt have hot water and heating. They turned up on time arranged and rapidly swapped my boiler over so I had heating and hot water. Would highly recommended.

Last year we had an issue with our boiler, Installers couldn't sort it out and was costing too much money with the the repairs. That's when we found Allstar systems, and our boiler never had any issue since last year,. We have booked for the annual service again this year and the service was again much satisfying. Would definitely recommend to everyone.. Thank you Allstar ? ?

First class service when our old boiler broke down. Reliable, on time and exceedingly friendly. What looked like a substantial job to me was finished in under a day. All paperwork, registration and extended warranty came through exactly as promised.

I can highly recommend this company

Allstar Systems installed a new replacement gas boiler for me a couple of years ago in my new home in Norwich and they have completed the annual service on it twice since then. All is going well, and I am very pleased to have a new (and much more efficient) Worcester Bosch condensing combo boiler installed, especially since the recent drastic increase in the cost of my gas by over 90 percent in April 2022!

I had a 6 year old thermal store cylinder which failed and flooded my kitchen and dining room. I contacted Allstar Systems and William came round the same evening to discuss options. I now have an efficient unvented hot water system along side a fully pumped sealed s-plan heating system with the cylinder relocated next to the boiler. New pipe work was required due to the relocation of the cylinder which left very little visible disruption. The installation was dealt with promptly and efficiently. I was kept informed of all changes. I’m extremely pleased with the result and would not hesitate in using the company again or recommending them.
