I specialise in boiler upgrades and full Central Heating installation. I can install any make of boiler though I would usually recommend a Vaillant. I also undertake all the aspects of the plumbing and electrical work involved. I can diagnose and repair problems to most boilers and central heating systems. Parts for most of the major boiler manufactures can be obtained on the same day but for some of the more unusual parts may take a couple of days arrive.
