Do You Need Planning Permission to Install a Wood Burning Stove?
In the UK, you don’t need any prior planning permission to install a wood burner, if the work is carried out by a HETAS installer. In this case, your installer is qualified to certify the works themselves, and will issue a certificate of compliance as proof. This will be signed by your installer and used to notify your council of the building work.
If you fit your stove yourself, or have a non-HETAS installer do the job, you will need to tell your local Building Control department before you start any work. This isn’t strictly planning permission, but is a necessary step. When the work is complete, they will need to inspect it to ensure all building regulations have been met. This will be at your expense, so factor this into your stove budget. Be aware that failure to follow the guidelines could result in a penalty!
Once the stove is properly fitted, you will need to make sure you have a notice plate completed. This is another regulation that records all the details of your stove, hearth, chimney and flue. It should be placed by your hearth, electric meter or water stopcock.
If you live in a listed building, it is possible you might need proper planning permission. Check with your local council before hand, if you do.
You will also have to check whether you live in a smoke control area. If so, you will need to make sure you buy a DEFRA approved stove or an EcoDesign stove.
