We had a new boiler installed in a different location in the kitchen and an additional towel radiator installed in the upstairs bathroom. Floor boards had to be lifted and all pipework had to be re-routed to the new boiler location. Stephen and his labourer did a great job with a tricky install which now looks great. Everything was put back as if job had not happened. In summary: Fair and realistic price, arrived on time, excellent communication throughout job, sound advice on possibilities, warranty paperwork (via Worcester Bosch) and "house gas safety check" paperwork done immediately after completion.
I found Stephen was adaptable (when I changed my plans slightly) and basically an enjoyable chap to deal with. We will be using Priory plumbing and heating again for further work in the future. Happy to recommend them.
