Building Regulations

Building regulations set standards for the design and construction of buildings. Their main purpose is to ensure the health and safety of people in or around those buildings. Energy efficiency measures are also incorporated in the building regulations.

Guidance on wood burning appliances
Most installation work relating to solid fuel, including firewood, wood chips and pellets and the associated systems for heating, controls, hot water etc are subject to building regulations. Notify the local authority of your plans - the building standards surveyors can be contacted through planning and building standards offices.

In the first instance -
For information on domestic combustion appliances and associated works not requiring a warrant (Domestic) click here.

For information on non domestic combustion appliances and associated works not requiring a warrant click here.

Work not requiring a warrant must still comply with the building regulations - if in doubt ask a building standards surveyor first.

Technical handbooks
New technical handbooks - one domestic and one non-domestic - are now available from the Building Standards Division website.

These provide guidance on achieving the standards set in the Building (Scotland) Regulations 2004 and incorporate changes adopted in October 2010.

The guidance in standards 3.17 to 3.22 applies to solid fuel appliances with an output rating not more than 50 kW.

The relevant sections for installers of wood fuel appliances are:
3.17.0 Introduction
3.17.4 Solid Fuel appliance installations
3.17.7 Labeleing
3.17.8 Extract fans
3.18 Combustion appliances - protection from combustion products - chimney systems - Warning: Very low flue-gas temperatures are achieved by modern, high efficiency appliances, particularly during night conditions, thus causing condensation. Chimney system materials need to withstand these aggressive situations.
3.19 Combustion appliances - relationship to combustible materials - protection from radiated, convected or conducted heat or from hot embers expelled from the appliance.
3.20 Combustion appliances - removal of products of combustion - products of combustion must be carried safely to the external air.
3.21 Combustion appliances - air for combustion - receives air for combustion and operation of the chimney so that the health of people within the building is not threatened by the build-up of dangerous gases as a result of incomplete combustion
3.22 Combustion appliances - air for cooling - air for cooling so that the fixed combustion appliance installation will operate safely.
3.23.0 Introduction
3.23.4 Bulk storage of woody biomass fuel
3.24.0 Introduction
3.24.4 Storage containers for solid woody biomass fuel

A building warrant is required for a solid fuel appliances with an output rating of more than 50 kW:

It is expected that specialists will design non-domestic sized combustion appliance installations in accordance with general standards provided in the Practice Standards produced by the British Standards Institution (BS EN or BS). A few large dwellings may require such installations.

If you are managing the installation yourself your local authority building standards surveyor will be able to advise. If you are employing a contractor make sure that all the necessary standards are being met.

HETAS - the Heating Equipment and Testing Scheme - is the official body recognised by the UK government to approve solid fuel domestic heating appliances, fuels and services.  Its work in approving products covers boilers, cookers, open fires and stoves and room-heaters.
