How to get it right: Building control exemptions (or when you DON'T need building regulations approval)
While we love to be involved, there are times when you won’t need a Building Regulations application. Whether you are carrying out building work yourself, or employing a builder, there are a number of building regulations exemptions to both work and buildings that don't need building control approval.
The following is intended as a guide but you should always check with your local LABC team if you're in any doubt or need clarification. You can also view Planning Portal’s interactive guides for more information.
Remember, these exemptions only relate to building control applications and you may need to apply for planning permission separately, particularly if you live in, or are carrying out work, to a property that is listed or within a conservation area.
Work that does not need building control approval
- Maintenance work
- Minor repairs
- Replacing less than 25 per cent of an item, like-for-like
- Additional power or lighting points and switches (except around baths and showers)
- Alterations to existing circuits (except around baths and showers)
- Like-for-like replacements of baths, toilets, basins or sinks
- Boundary or garden walls, fences and gates
- In some cases, works that are being carried out by competent registered persons (check details for this with your local LABC team)
Buildings that do not need building control approval
- Greenhouses (providing they are not used for retail, packing or exhibiting)
- Some agricultural buildings (check with your local LABC team)
- Temporary buildings (erected for less than 28 days)
- Some ancillary buildings such as estate sales buildings and building site offices without sleeping accommodation
- Some small detached buildings (check with your local LABC team)
- Buildings that are not frequented by people (check with your local LABC team)
- Detached single storey buildings, including garages, that are less than 30m2 floor area and contain no sleeping accommodation, and are at least one metre from any boundary or constructed of non-combustible materials
- Detached single storey buildings that are less than 15m2 floor area
- An extension to a building at ground level consisting of a porch of less than 30m2 floor area and separated from the house by an external type door
- A carport open on at least two sides
- A covered yard or covered way less than 30m2
- A conservatory or porch that is less than 30m2, with a significant proportion of the roof and walls glazed (no % given), it must be at ground level, it must comply with relevant sections of Part K (glazing), be thermally separated from the dwelling by external quality windows and/or doors and the buildings heating system must not be extended into the conservatory or porch.
- Crown property
- Buildings subject to the Explosives Act
- Buildings other than houses or offices erected on a site licensed under the Nuclear Installations Act
- Buildings included in the Schedule to Section 1 of the Ancients Monuments and Archaeological Areas Act
Don’t forget that you might still need approval for any enabling works. For example creating a wider opening into an exempt conservatory would still need approval for the structural alteration to widen the opening.

Building Notice
Submitted 6 years 2 months ago
I wonder if any or cumulative notices applied at Grenfell?
This system leaves building inspectors in effect as the designers with liabilities attached, where often small builders do not want thorough plans undertaken and rely heavily upon building control to give constant advice.
I fully support LABC and am a 'partner ' with them.
Mistake?

Sun room

Thanks for your comment.
If the sun room is attached and open to the house, it will not be exempt from the Building Regulations. Please contact your local authority who will be able to offer pre-application advice on your proposals and on how to submit a Building Regulation application.
If the sun room is to be separated from the house, it could be regarded as a conservatory and be exempt from control under the Building Regulations:
CLASS 7
Extensions
The extension of a building by the addition at ground level of-
a) a conservatory, porch, covered yard or covered way; or
b) a carport open on at least two sides;
where the floor area of that extension does not exceed 30m2, provided that in the case of a conservatory or porch which is wholly or partly glazed, the glazing satisfies the requirements of Part N of Schedule 1.
You may wish to contact your Local Authority Building Control to talk this through.

As the porch is exempt from control under the Building Regulations, no LABC inspection will be carried out.
However, generally incorporating lead or timber at the base, particularly as it is under the roof, would not cause too much of a problem. There is a chance of some water dripping onto the wall which may cause some staining in time.
I hope that helps,

Extension conversion
Submitted 5 years 10 months ago
We're in the middle of converting an out building which is joined to our property into a toilet
Does this need to meet strict regulations as we feel the building inspector is being unreasonable due to the fact the building is already been built since 1970 and were just changing the use of the building
The main house was built over 300 years ago and this extension has been built around 1970
Any advice would be very helpful as he has already tried to get us to battern and board all the internal walls of the old building which is non compliant to regulations due to the age of charticistac of the building
