Building control service

Building regulation applications

We would like to bring to your attention that new legislation has come into force from 1 October 2023 which puts additional requirements on the client under the Building Regulations 2010 (Amended), in Part 2A,11C(1) where the client is required to appoint a suitably competent Principal Designer and Principal Contractor (please note this can be the same person/company). Please provide the name, contact address and contact number for these persons as soon as possible. If you do not notify us of these appointments, we will assume that you will be acting in both capacities and will be taking on these legal duties.

The new regulations are a result of the Building Safety Act 2022 which is intended to drive up competence in the construction industry and improve quality and standards in our built environment.

Search building control applications

Most building work, whether new, alterations, extensions or change of use, requires building regulations approval. You can make one of two types of application - full plans or building notice. For further information see the Planning Portal.

Full plans application

Extending, altering or building a non-domestic building usually needs a full plans application. You need to send us detailed plans, specifications and structural calculations. We’ll issue an approval notice if the plans meet regulations, or contact you if plans need amendments or must be rejected.

If the work is carried out in line with the approved plans, it will meet the regulations, and you can give the approval notice to mortgage lenders solicitors, and surveyors.

Building notice

Building notice approval allows building work to be carried out without detailed plans. It is used when the work is straight forward, and the builder knows the regulations well.

A building notice is generally suitable for small alterations and projects – for example an additional window or removing an internal wall. It’s a faster process meaning you can start 48 hours after deposit (or earlier) it can’t be used if you are going to be building over or close to a public sewer or altering a commercial building. N.B. you need to be aware that a building notice puts more responsibility for knowing and complying with the building regulations on the person carrying out the work and the property owner.

We inspect the work as it proceeds, and may request further information such as structural design calculations, construction details and specifications of materials. You can save time and money by not having to prepare and submit detailed plans, but if the completed work does not meet regulations, there may be a delay and extra costs to correct it.

Apply for building notice


You can apply for a regularisation certificate for unauthorised building work carried out on or after 11 November 1985 and which should have been submitted to the Building Regulations procedures.
