Deciding on a new boiler can be a daunting prospect. We are here to give you all the impartial advice you could need, to ensure you have the correct boiler installed, leaving you with hassle free central heating system for years to come. All our boiler installations come with a minimum 2 year guarantee, but with many of the major manufacturer's we have secured 5 years warranties, including Parts & Labour giving you complete peace of mind from start to finish. Power flushing your system can prolong the life of your heating system, making it last longer, reduce the risk of the boiler breaking down, will have warmer radiators and in turn, a warmer house.

We are registered with Gas Safe Register, and have many years' experience repairing, servicing and installing boilers, gas fires, cookers, water heaters & warm air units. We provide the following services and if you do not see what you require here, just give us a ring on 0208 420 2344 and we can advise you.
