An installer registered with a Competent Person Scheme is qualified to carry out specific types of work in accordance with the Building Regulations and will deal with Building Control issues for you. You will usually have access to insurance backed warranties and a robust complaints procedure to use in the unlikely event work is found to be non compliant.

An installer registered with a Competent Person Scheme will notify the local authority on your behalf and will issue you with a certificate on completion which can be used as proof of compliance. It will also show up on a solicitor's local authority search when you sell your home.

If you do not use an installer registered with a Competent Person Scheme then you will have to submit a building notice or full plans application and pay a fee to Building Control for inspection of the work you have carried out.
