  1. What is CPS?
    • Stroma Certification offers Competent Person Schemes (CPS) covering a number of different trades. Membership of a CPS allows installers to self-certify their installations as meeting the Building Regulations. A Competent Person membership is awarded to the organisation, not to an individual installer. Approval is gained through an independent audit of company procedures against Building Regulation requirements, followed by examination of a relevant recent installation.
  1. What do we mean by self-certification?
    • Self-certification includes all work done under the Building Regulations. It was first introduced in 2002 for installations such as replacement windows, heating or electrical work. Once notification of an installation is received by Stroma, we issue a certificate of works to the client confirming that the installation is certified as competent.

  1. What CPS measures can Stroma certify?
  • We have been authorised by the DCLG to run CPS schemes for the following measures:

    • The information pack contains documents for GDI, CPS and MCS schemes so be sure to read all the ones relating the CPS certification carefully.

    Fill in the application form

    Pay the fees and return the pre-visit questionnaire

    • You will receive one invoice which keeps the application process simple and helps you to manage your finances simply.
    • A pre-visit questionnaire will be sent with the invoice and is used to collect some advance information about the company, the staff involved and the installation itself.
    • This form should be completed in full to ensure your application can be progressed without delay.

    We will visit you to carry out an assessment

    • Our assessor will audit your written documentation, then they will undertake a site assessment(s) to cover each type of work for which you have applied.
    • During the visits you’ll be assessed against the relevant scheme standards.

    Submit any outstanding evidence

    • If the Stroma assessor identifies any issues during the visit, you will usually be given an opportunity to put them right.
    • Once the problems have been rectified then evidence needs to be sent to Stroma as proof of this. Following satisfactory receipt of evidence your assessment can be signed off and final approval given.

    Congratulations – you are certified!

    • Once this process is complete you will be recommended for certification as a member of our Competent Person Scheme.

  1. What does CPS certification mean?
    • CPS certification covers the installation, not the design. A CPS notification confirms that the work conforms to all Building regulation requirements (from Part A to Part P).

  1. What are the key requirements for CPS certification?

    In order to maintain your CPS membership, you will need to:

    • Ensure that your operatives have the correct level of competency (i.e. hold relevant qualifications and adhere to the certification standards).
    • Demonstrate adherence to relevant technical and safety standards.
    • Demonstrate high standards of professionalism and best practice.
    • Adhere to Stroma Certification’s regular checks and standards.
  1. How do I notify my installation work with Stroma?
    • All notifications are managed by our online members area. Once work has been notified, a certificate of works will be printed and posted to your client based on the details provided to us. In the event incorrect details are provided the member will be asked to re-notify and incur an additional notification fee. The certificate will be posted 7 days after the notification is made and once Building Control have been notified.

  1. What is an Installer Bundle?
    • Installer bundles are unique certification packages which allow members to become certified for multiple measures. Tradespeople moving from other CPS schemes or who have taken GDI or MCS elsewhere can also include CPS for free as long as they renew without undergoing an assessment. You must then notify the work through Stroma. Notifications are made simple as all members have access to the notification system on our online members area.
