Assessment Information

The Part P assessments are designed for installers that carry out electrical installation work in dwellings under the supervision of a Qualified Supervisor. There are two Part P assessments:

  • Defined Scope – for installers that carry out electrical work as part of their work activity e.g. plumbers, heating installers, kitchen and bathroom fitters
  • Full Scope –  for installers whose work may include full domestic electrical installations, including installing new consumer units or ring mains

Both of the above qualifications apply to electrical work covered by Part P of the Building Regulations and BS7671:2008(2011) 17th Edition Wiring Regulations.

Please note that the above qualifications are aimed at installers who work under the supervision of a ‘qualified supervisor’. This qualification DOES NOT meet the minimum requirements for applicants wishing to achieve ‘qualified supervisor’ status.


Applicants should have previous experience in the installation and maintenance of domestic electrical installations. Applicants for the full scope assessment are required to hold the defined scope qualification.

Candidates wishing to take re-assessment must have held the assessment element previously – if this element has expired within 12 months of the assessment date, it will be necessary to take the initial assessment.

Further Information

The defined scope qualification can normally be completed over a five-day period and the full scope qualification can normally be completed in one day. The assessment of both qualifications normally consists of a combination of both practical and theory examinations.

Expiry Information

Certificates are normally valid for 5 years. On expiry, candidates are eligible to take a shorter reassessment.
