We do not have a showroom which helps keeps costs low and doesn't tie us to a small selection of stove manufacturers. This means we are often able to source stoves at very reasonable prices for our customers. We only purchase parts and materials from quality suppliers. For customers living within 15 miles of Hitchin, Hertfordshire; we provide a free survey and quotation service and will visit early mornings and at weekends if it is more convenient.

Being HETAS trained and registered means that your installation will meet with current building regulations. You will not have to apply for permission from the local council to install your stove and it will also not need inspecting afterwards. A HETAS approved installer has to undertake specific training and then keep up with the latest changes in the industry and regularly have their work inspected. They also must have adequate public liability insurances, therefore using a HETAS engineer ensures that all aspects of your installation are safe and legal.

Gareth has installed hundreds of stoves throughout Herts, Beds, Bucks, Essex, Midlands and North London over the last few years and has a wealth of experience and a trusted reputation. Gareth achieved his HETAS certification in 2012 and has been installing dry systems ever since.

If you are thinking of purchasing a woodburner to connect to your central heating then you will need to check on the HETAS website for a wet system installer. Search for HETAS approved engineer on the HETAS website
