Competent Person Scheme (CPS)

Competent Person Scheme

Join to start self-certifying your own work in compliance with the Building Regulations

CPS membership will allow you or your employees to self-certify that your work complies with the Building Regulations in England and Wales, saving you time and money by removing the need to notify Building Control in advance, or having to pay the Building Control fees normally associated with an installation.

It is a legal requirement that certain work should be notified and CPS membership is the most effective way of complying as well as saving, on average, £241 in Building Control fees for every piece of notifiable work you or your operatives carry out.* It also lets your customers know that you and your employees' work is of a high standard and that regular assessments take place to demonstrate the ongoing competence of you and your operatives.

* Average cost from: DCLG, (2012) Changes to Part P (Electrical safety - Dwellings) of the Building Regulations in England: Consultation stage impact assessment.

Scheme Requirements

The following general conditions must be met by all CPS members:

Trade Building Regulations Key Supporting Standards
Electrical Approved Document P BS7671 (the current IET wiring regulations)
Microgeneration Several Approved Documents MCS scheme standards
Heating Approved Documents G,J & L Building Services Compliance Guides
Ventilation and air conditioning Approved Documents F & L Ventilation Compliance Guides
Plumbing Approved Documents G & H Water Supply Fittings Regulations
Building Fabric Several Approved Documents

Relevant Standards: You must hold, or have access to, the technical standards for the approved scope. Competencies are published in specifications referred to as Minimum Technical Competence (MTC) documents. However, the relevant primary approved documents and supporting standards vary by trade as shown below. Note that while the main Approved Document is listed, any self-certification is a confirmation that all relevant parts of the Building Regulations have been met.

Qualifications - the key requirements of the MTCs are met via qualifications and/or training. NAPIT has produced guides to qualifications for most trades.

Legal Requirements – Work must comply with the Building Regulations 2010 (as amended) and be notified as described below.

Insurance - You must have a minimum of £2m public liability insurance.

Instruments – You or your operatives must have access to sufficient instruments to carry out tests relevant to your scope of work as well as an in date calibration certificate for you or your employees' equipment where applicable.

Inspection – You must make available suitable installation work to demonstrate compliance and competence.

The inspection will look at the work itself and assess the competence of individuals carrying out the work. Evidence of how you or your employees comply with other requirements (risk assessments, insurance evidence, quoting etc.) will also be assessed.

Notification – Self-certification must be carried out by notifying NAPIT within 21 days of completion of an installation, a Building Regulations Compliance. (A certificate issued by NAPIT to the building owner that can be used of evidence of compliance with the Building Regulations).

Website Listing – Once successfully registered, your business will be added to the NAPIT online search facility, Competent Persons' Register, Registered Competent Person Electrical search facility (for Full Scope electrical members only).

How CPS relates to MCS and EEM

The competence requirements of the three schemes are demonstrated via similar routes, but both MCS and EEM have additional company requirements (as well as a wider geographic coverage). Because of this overlap, if NAPIT assess you or your employees under MCS or EEM, you may be eligible to carry out CPS work relating to these schemes and self certify without incurring any additional membership charges.
