* 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.
* 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.

* We only purchase parts and materials from quality suppliers and if you live in 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.

HETAS installer certificate

* 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 undertakeregular 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.

Why choose GTD Installations Ltd?

It's Winter!

You should be starting to enjoy your woodburner every day now

Its getting colder and wetter now and soon will be too dangerous to get on your roof to fit cowls or bird guards, so you may have to wait a while if you need one. If you didn't get your chimney / flue swept in Summer, then you may find you have to wait a while as the sweeps are busy at this time of year.
