Building Regulations for Wood Burning Stoves
A stove is a notifiable building work item. The rules are not complicated, but skipping them causes real problems when you sell the house or make an insurance claim.
Yes, a stove installation is notifiable work
- A hearth of the correct thickness and size for the appliance
- Manufacturer clearances to combustibles respected, or heat shielding used
- A flue that is the right diameter, sound and correctly terminated
- Permanent air supply where the appliance output requires it
- A carbon monoxide alarm in the same room
- A data plate recording what has been installed
The two legitimate routes
Registered installer. A HETAS registered installer certifies the work and notifies building control on your behalf. The certificate lands with you shortly afterwards and nothing else is required.
Local authority. You apply for building control approval before the work, pay the fee and arrange inspection. Slower and usually more expensive, but the route if the fitter is not registered.
Why the certificate matters later
Conveyancing solicitors ask for it, home insurers ask for it after a chimney fire, and a buyer's surveyor will flag an unregistered appliance. It is far cheaper to have the certificate on day one than to chase it years later.
What the regulations actually require
- A hearth and clearances to combustibles that suit the appliance
- A flue that is the right size, condition and height for the stove
- A carbon monoxide alarm in the same room, correctly sited
- A permanent air supply where the appliance output calls for one
- A data plate recording the installation, fixed where it can be found
Listed buildings and conservation areas
Building regulations still apply, and consent may be needed on top where the work affects the fabric or the roofline, for example a new pot, cowl or twin-wall flue. We flag this at survey stage so it is dealt with before anything is ordered.

Common questions
Do I have to notify building control?+
Yes. Either a registered installer self-certifies the work, or you apply to your local authority building control and pay for their inspection.
What happens if a previous stove was never registered?+
It can usually be regularised: the installation is inspected against current requirements, put right where needed, and certificated. Worth doing before a sale.
Is a carbon monoxide alarm compulsory?+
Yes, a CO alarm is required in the same room as the appliance and it should be sited to the manufacturer's instructions rather than tucked out of the way.
Does the chimney need a plate?+
A data plate recording the flue type, size and any liner should be fitted near the appliance or at the meter, so the next installer or sweep knows what they are dealing with.
