Do you need planning permission?
This will depend on the nature and extent of your installation, if you are installing a stove and need to build a new chimney then you will need to go through the planning and building regulations. The UK Planning Portal gives excellent and clear advice regarding planning permission.
If your property is in an Area of Outstanding Natural Beauty and you need a twin wall chimney installation you will probably need planning permission or other consents.
If your property is a Graded Listed building you will in all probability need planning permission, or certainly consent.
However if you are just installing a stove in an existing fireplace or it is a relatively simple installation the process is simpler, though the installation must still comply with Building Regulations Part J which deals with combustion appliances. You can view them here :- Building Regs Part J (pdf)
If your building work consists only of the installation of certain types of services or fittings (e.g. some types of drain, fuel burning appliances, replacement windows, WCs, and showers) and you employ an installer registered with a relevant scheme. That installer may be able to “self-certify”; so you will not need to involve a Building Control Service. However, this concession is strictly limited to the specific type of installation described and does not cover any other type of building work.
