Why choose us?

Independent and Local

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 but can also undertake any building works that may be necessary for the installation.

If you do buy a stove through us we will provide a stove pipe thermometer for free so that you know when you are using your stove and fuel at is best. If you are looking to buy a thermometer, visit our shop, where you can enjoy free delivery if you live local to us and pay cash on delivery.


We also have a chimney sweeping company so no need to organise a sweep of the chimney before installation and we will advise on any maintenance, if needed, during future sweeps.

We only purchase parts and materials from quality suppliers and if you live near Hitchin, Hertfordshire; we provide a free survey and quotation service. We can visit early mornings and at weekends if it is more convenient for you.
