Most of our customers here at chimfit fit their stove and or flue liner themselves. You do not have to use a professional installer if you are DIY savvy and have general competence, If you are installing the wood burning stove into an fireplace and not installing a new chimney liner then the installation is very straightforward. Installing a chimfit flexible chimney liner or complete twin wall flue system is a larger project and may involve ladders/scaffolding if your roof does not have external access, this is since it is needed for the job, is still is however technically straightforward. Our twin wall chimney system simply slots together, no specialist knowledge or skills are required.

If you are thinking of completing the work yourself then you should contact the local council Building Control, they can then inspect the work you have done and sign it off if it is up to standard. Alternatively if the work is done by a professional installer (Which we here at Chimfit recommend) who is accredited by one of the relevant Competent Persons schemes such as HETAS then they can sign off their work themselves.

Old houses will usually have exposed brick inside the chimney so it is not a legal requirement to line these older chimneys with chimfits liner unless they are broken or leaking, there are often advantages to lining such as increased draw. Installation of a wood burning stove and/or new flue system would not usually have anything to do with the local planning authority. If your property is a Listed Building then permission may or may not be required. If you intend your new chimfit flue pipework to run up the outside of an external wall then depending on the position you may need to check with the local Planning Department.
