Absolute impeccable service ! Came out 10 minutes after calling, following an emergency plea on behalf of my 90+ year old grandparents. Its 2 days before Xmas Eve and 6.30pm at night but he still came to inspect their faulty boiler and cold radiators. Luckily enough they lived 2 roads away from his base, which may have helped us out. A thorough professional job done, listed everything that was installed wrong, went up in the loft to check things, and also outside the house even though its a very dark and bitter cold night. An absolute god send !
