I cannot fault Andy at all. Genuinely nice guy, great communication and completed all work without any issues. A great company to find, will definitely be using again and would highly recommend.

The boiler and new system work well and that hopefully continue. Just hoping it is energy efficient.

We had to make a decision about which boiler to choose and settled for a Viessmann. The choice has been great as the boiler performs well.

Helpful Report
Boiler installed by Chris Sullivan works without problems… looking forward to seeing efficiencies of having a new boiler translate into reduced gas usage..
Helpful Report
We are delighted with our new Viessman boiler. It is very quiet, reliable and cost-effective. The service from the installation company was excellent. We are so pleased we changed our old boiler for a Viessman. Our app is operated through the installation company so any queries have been directed there.

No problems so far
Helpful Report
We were extremely pleased with the work, and the way the work was carried out, by Rhydian James. The boiler is now about ten months old and all is well. A ten year guarantee is a comfort. Thank you.

Helpful Report
Top quality boiler at an affordable price. Highly recommended
Helpful Report
The boiler installation went very smoothly. For the first few weeks of operation, the hot water supply was a little erratic, but is now very reliable. The heating has always worked very well. It is too early to say if gas bills have been significantly reduced, but they should be as this is a far more fuel efficient boiler than the one it replaced.
Helpful Report
The boiler works reliably but I have not yet worked out if it is more efficient than my previous boiler - and that will be hard to get a true comparison. The team that fitted it did a good job and having an agreed price before ordering was a real plus point.
Helpful Report
Our new boiler was fitted and running without any fuss or problems. It has functioned well since it was installed last autumn.
