There are a few important considerations you must think of before you commence any work, in order to create an attractive, efficient and safe fireplace in your home. All work must adhere to Part J of the Building Regulations, which addresses the installation and construction of flue linings, fireplaces, hearths and chimney breasts of any combustible appliance. If you reside in a designated conservation area or a listed building you should check with local council if planning permission is needed for a fireplace installation in your house.
