After speaking to several heating engineers we decided to go with Cinergi to upgrade our old back boiler for a new Worcester Bosch combi.

We are so glad with our choice and would recommend Ian to anyone. We are delighted with the service we have received, we were never without hot water and he worked in a professional and friendly manner.

Ian’s quote was clear and itemised so we could see exactly what we were spending our money on and he was able to offer us helpful advice on the best solution for us.

We Chose Cinergi to replace our 17 year old boiler, we contacted Ian at Cinergi through the Bosch Worcester accredited installer website with a few other companies.

We had several other companies attend but they wanted to remove some of my decking to install a soakaway buried in the ground with limestone chippings, Ian was the only one who said there was no need for that to be done – he would install a Sentinel condensafe condensate neutraliser.

Ian was very professional, friendly and knowledgeable i would not hesitate to recommend him his workmanship was fantastic.

Cinergi  were able to fit a new boiler at short notice with a more than reasonable quote. Ian arrived as scheduled, was very friendly and knowledgeable and got straight on with the job. His workmanship is excellent plus he takes away the old boiler/rubbish, making sure the job is left tidy. During the installation I presented Ian with a separate bit of work, moving a problematic pipe for an existing radiator. He solved the issue with some clever pipework which he was able to hide leaving a perfect finish.

Overall Ian was brilliant at his job and is obviously very experienced and skilled. I would highly recommend him to anybody and we will definitely be using Cinergi in the future.
