Competent Persons Scheme for Plumbers

Competent Persons SchemeThe Competent Persons Scheme was introduced by the Department of Communities and Local Government (CLG) to enable companies to self-certify plumbing and heating works that fall under the scope of Building Regulations. Self certification providing a much more cost effective route as compared with the alternative of notifying work through local building control bodies.

To self-certify plumbing and heating works that fall under the scope of Building Regulations, companies must become certified Competent Persons Scheme installers through a Competent Persons Scheme Certification Body such as APHC Certification Ltd.

Plumbing and heating companies can join the scheme provided they meet the scheme requirements as outlined in the scheme documents, available to download below.

Following completion of the initial application form, the assessment process comprises of:

1. Desktop evaluation of the company management system. This part is a pre-check to confirm company readiness for its assessment under the scheme. Information on company procedures is provided to APHC Certification ltd. for a desktop evaluation which takes place at our premises.

2. Head office assessment of the management system. This part of the process assesses the use and application of the company management system at the applicant company's business or home office.

3. On-site assessment of installed work areas. This part assesses competence to install each of the technical work areas that form the company's application under the scheme. The company will need to show one example of an installation for each work area it wishes to be certified to install.

Once approved, companies will have the ability to install and self-certify a range of permitted plumbing and heating works under the Competent Persons Scheme to Building Regulations from £1.85 per online notification.
