We had an issue with our heating system where the radiators were getting hot when the hot water was running and the overflow was leaking water out from the header tank. We contacted Zach on a bank holiday and he came straight out, diagnosed the problem, ordered the parts and quoted for the job accurately. Returned when he promised with the correct parts and completed the works professionally. He left our house clean, tidy and with working heating and actually didn't charge the earth. (Even though it was a bank holiday) I would, and will, highly recommended this company. Keep up the great work!
