About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

Extended Access

The Extended Access Request form can only be completed by an MCS Contractor* that is currently certified. If you are no longer certified or trading, please submit a general enquiry email, and MCS will handle the request to amend the MCS certificate.

Complete the form below to register an Extended Access Request to the MCS Installation Database. This form is only required if one of the following instances apply:

  • You wish to register a new certificate and have missed the 10 working day window since commissioning, OR;
  • You wish to amend an incorrect commissioning date to an existing certificate, OR;
  • You wish to amend an existing Compliance Certificate.

Please note all other amendments do not require Extended Access and can be made by the original MCS Contractor.

Should you wish to request access for more than 10 properties, please email requesting the Bulk Upload Spreadsheet.

*MCS contractor refers to any installation organisation that holds MCS certification for its installation services

C. Concise reason for extension request


Once this information has been submitted your request will be sent to your Certification Body within five working days. The Certification Body will then assess the request and provide the MCS Administrator with confirmation as to whether extended access can be granted (the timescale for this response is decided by the Certification Body). If and when you receive a reply email stating your access has been granted, you will then have 24 hours to make the necessary amendments on the MCS Installer Database.
