Common Exempt Projects

Some building types and extensions are classed as exempt under the building regulations meaning an application doesn’t need to be submitted to building control. The most common exemptions are detailed below but beware that they may still need Planning Permission.

Conservatories

A conservatory built at ground level and less than 30m2 in floor area and thermally separated from the existing house is normally exempt provided that glazing and any fixed electrical installations and heating installations comply with the applicable requirements of the building regulations.

Garages

The construction of a new attached carport, open on at least two sides, would not normally require building regulations if it is less than 30m2 in floor area. Construction of a non-combustible detached garage less then 30m2 would not normally require building regulations approval as long as it doesn’t contain sleeping accommodation. If the construction is of combustible materials the garage must be at least 1m from the property boundary.

Porches

Construction of a porch built at ground level of less than 30m2 in floor area and thermally separated from the existing house, is normally exempt provided that the glazing and any fixed electrical installation comply with the requirements of the building regulations.

Sheds

Construction of a small detached building such as a garden shed or summerhouse in the garden will not normally require building regulations if the floor area of the building is less than 15m2. If the floor area is between 15-30m2 you will not normally require building regulations providing that the building is either at least 1m from the boundary or it is constructed of substantially non-combustible material.

Full details of all the exemptions can be found in Schedule 2 of the Building Regulations. Alternatively, if you are still unsure if your project is exempt please use this enquiry form.
