Domestic - Regularisation (Retrospective)

If you didn’t apply for building regulations at the time the works were carried out, you can apply to have the work regularised by us. However, the work must have taken place after 10 November 1985.

A Regularisation application may mean that work has to be opened up or additional information provided. There is no guarantee that we will then issue a regularisation certificate. This will depend on the standard of the work meeting the building regulations at that time and all the necessary information being supplied.

VAT is not charged for this application type (April 2024)

Building Control Approval with Full Plans Application.

In this case, you as the building owner or your agent/architect will submit an application with plans showing full construction details and specification of the work together with any relevant structural calculations. A Building Control Surveyor will check the plans and specification for compliance. If items do not comply a list will be sent to the Agent for a response. An application can be Approved, Conditionally Approved or Rejected. Once construction commences a Building Control Surveyor will visit site to inspect the works. The fees are payable in 2 stages. The Plan fee must be paid with the application. Once work commences on site we will raise an invoice for the Inspection fee.

Building Notice Application.

A building notice can only be used for works to a dwelling. It is generally used for minor works such as removal of an internal load-bearing wall, and/or where the person carrying out the work is familiar with current building regulations. No plans or construction specifications are required, and any that are submitted will not be checked for compliance. Compliance is checked via the site inspections undertaken by the Building Control Surveyor, and they may request additional paperwork such as structural calculations and electrical certificates. One advantage is that it allows work to start 48 hours after submission of the

Regularisation Application.

This application is used for works that have already taken place illegally without the submission of a Full Plan or Building Notice application after November 1985.

Some works may be exempt from the building regulations such as; new garages, conservatories and certain works to provide access or essential facilities for disabled people.

Electrical Work.

An additional charge will apply when the electrical work is carried out by a person who is not a Part P registered electrician. A Part P registered electrician is a qualified electrician who also has the necessary building regulations knowledge to enable his/her accreditation body to certify his/her work. In order to recover the Local Authority costs, if anyone other than a Part P registered electrician undertakes the electrical work, an additional charge is payable.

Additional / Supplementary Charges.

The Standard Charges have been set on the basis that the design and building work is undertaken by a person or company that is experienced and competent to carry out the work. If not, the work may incur supplementary additional charges. Where plans and/or calculations have been checked and subsequent amendments or redesigns are submitted, the council reserves the right to make supplementary additional charges.
