I contacted Rudkin & Herbert via the links on the Worcester website as well as 2 others. One never even got in touch, the other came and wrote his quote on the back of his business card. The visit and quote I received from Rudkin & Herbert was full and clearly laid out listing the all the items and fully itemized costs and the work needed was fully explained and he also left brochures for the boiler we were looking at. Installation was not straight forward but the engineers performed brilliantly and the system was installed and set up and handed over in full working order and the engineer went through the controls and finer points with my wife. We are also going for the 5 year service plan which is the way forward to keep the system working to its best potential. Excellent performance overall and really pleased with the service.
