- Mr. P, Boiler / Central Heating Installation

Just wanted to pass on our many thanks and gratitude towards yourself and the company for all the hard work on our house. Jason has been fantastic and really hardworking over the 2 weeks. Everything is immaculate and has been carried out to such a high standard. We were so pleased that everything ran so smoothly and there were no typical 'builder' like delays or excuses. It was a great relief that we didn't have to organise anything. We are so pleased with all the work and have been happy throughout. We were really impressed with all the other workmen including the plasterer, electrician and tiler. There work has been to a very high standard also. Everyone at the showroom and especially Patrick were very patient with us and advised us very well. Please pass on our many thanks to Jason, the apprentice and the rest of their team for all their hard work. See you when we've got enough money for the kitchen to be done!

- Mr & Mrs C, Heating / Bathroom Installation

I think all the work here is finished and we would like to just ask you to pass on our thanks to all the people that did the work. They were very helpful and understanding when we had to ask them to move/stop work, the pipework is very neat and tidy and the work was carried out with a minimum of disruption to us.

- Part Vet Centre, Central Heating Installation

It has been a pleasure dealing with everyone in your firm. Cosmetically the bathroom looks lovely. Your team worked quickly, efficiently, tidily with as little inconvenience to us as possible. They were all polite and asked for our input when decisions needed to be made and explained anything we didn't understand. They are a credit to your company and I would not hesitate to recommend you to anyone.

Just a quick email to let you know that I am still in love with my bathroom (especially the shower) and my lovely, gorgeous, bright kitchen gives me a warm glow every time I enter it and I have even started cooking roast dinners in the oven you persuaded me to have fitted!
