Building work: competent person schemes

Many jobs in the home need to be notified to and approved as being compliant with Building Regulations by a Building Control Body, either your Local Authority Building Control or a private sector Approved Inspector. Competent Person Schemes allow individuals and enterprises to self-certify that their work complies with the Building Regulations as an alternative to these routes.

An installer registered with a Competent Person Scheme is qualified to carry out specific types of work in accordance with Building Regulations and should both notify the local authority of the work and issue you a certificate of compliance with Building Regulations either directly or through their scheme operator.

If you are going to use the Competent Person Scheme route, you need to ensure you use a competent person relevant to the work you are carrying out. The following lists the current schemes. Please be aware the list may change from time to time to include new schemes as they are approved, or to remove schemes as appropriate.
