Central heating system

Colin was very quick, efficient and knowledgeable on the problem and after visiting us late on the Fri 21st to assess the fault , he left us with a temporary fix/working central heating system and returned the next day (Saturday) with a new valve head assembly. The new part was fitted in less than an hour and the central heating is now working normally again. We are so pleased that Colin was able to fix this problem so promptly and we would definitely recommend him.
