Great service from start to finish
“Great service from start to finish. Firstly – Nina in the office offered a fast turn around for someone to come for a free quote and lucky someone was in the area so managed to get them round the same day. Any questions I had Nina was there to answer! And not to mention my quote was sent to me the same day and booked in shortly after. The men who worked on replacing and moving my boiler was amazing! Everything was kept clean and tidy, they was extremely polite and when explaining the job they made sure I fully understood everything – great communication! I will be using this company in the future and will be recommending as such a great service!”

Fantastic communication and professional approach
“I recently had my boiler replaced by the Heat Knights team. Communication with Simon was fantastic, I was kept well informed throughout the process. It’s very refreshing to see such a professional approach in this industry. The engineer that carried out the work was polite and worked diligently, even though it was the coldest day of the year, to get the boiler replaced so that the house was warm before my Son came home from nursery. He then proceeded to inform me about all the paperwork and functions of the new boiler. Highly recommended Simon and Heat Knights!”
