Is building regulations approval needed?Last updated: 18 November 2010 13:59 UK
Generally speaking, an application for building regulation approval is required for most types of development. The following commonly asked questions and answers may help you to decide whether any works you propose to carry out need approval. It is not possible to cover everything here, if you have a specific query not covered here, please email us at email@example.com
Planning permission may also be needed, please contact planning to check whether your proposals need planning permission.
The interactive house at the Planning Portal is a useful guide to both planning & building regulation requirements.
Build an extension to my house?
Yes- unless the extension is a garage, carport, covered yard, porch or conservatory see below.
Convert a loft/roof space to a room or rooms?
Yes – this can be complex, we recommend full architectural drawing and structural calculations are obtained and submitted on full plans building regulations application.
Yes - if the work involved is structural, removal or part removal of a load bearing wall, floor or chimney breast.
If the alteration involves the insertion of a beam or lintel, then building regulation approval is required. We recommend that a structural engineer is engaged to calculate the support & bearings.
Install Cavity Wall insulation?
Yes – if you use an approved installer they will normally submit an application on your behalf.
Replacement or new windows?
Yes – if you use a glazing/double glazing firm who are Fensa registered (Federation Self-Assessment Scheme), they will advise us on your behalf. If they are not FENSA registered you will need to submit details and attach building notice and replacement windows forms. There is a fixed charge, see our fee sheet. Non-domestic properties always require an application.
Construct a detached garage?
No – provided its internal floor area is 30m2 or less and is built substantially from non-combustible materials.
Construct an attached garage?
Yes – can be applied for by using either full plans application or building notice.
Construct a car port?
No – if its floor area is less than 30m2 and is open on at least two sides.
Construct a porch
No – provided it covers an entrance door and is less than 3m2 , the original access door remains in place and glazing is toughened or laminated. Note planning permission is required if this is over 3m2 floor area on the front elevation of the property.

Yes – the new approved document L1B means any changes to the thermal elements of a building will need consent (eg removal of roof tiles, render, plaster of walls, new roofing felt, new floor construction) providing the area is more than 25% of that element. Cost of upgrading the thermal element must be offset by energy savings (pay back) within 15 years.
