Class E – Flue for biomass heating system on residential

 

flue for biomassWhilst you do not need planning permission for a biomass heating system, you will need an external flue for the biomass boiler. 

For residential properties or blocks of flats, this is covered under Class E of Part 14. 

As long as the flue does not extend more than 1 metre above the highest point of the roof or in the case of a conservation area or world heritage site isn’t on a wall or roof slope facing a highway you are fine. You will not require planning permission.

Apart from these two minor restrictions on a flue for a biomass heating system you can crack on. 

If the building is listed you will require listed building consent.

Biomass is a renewable energy source, generated from burning wood, plants and other organic matter, such as manure or household waste. It releases carbon dioxide when burned, but considerably less than fossil fuels.

Biomass heating systems burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers.

For the commercial version of this, please see Class N of Part 14
