For people in Kent and SE London, we offer a fireplace and heating design and building service. Our surveys will visit you at home or on site and help to design a new fireplace and an efficient, green and economical heating system.  Outside the SE we can offer a design and supply service and help you or your plumber with fitting advise. 

We believe ECO should mean ECOnomical as well as environmentally friendly
