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.


MCS publishes statistics on the installations registered on the MCS Installation Database (MID) and the number of certified installation companies. The statistics are published on a monthly basis.

Please note, due to a large number of requests for historical Installer statistics, the Administrators of the scheme and have now been able to pull together more accurate data in regards to the total number of Installers on the Scheme, including the last financial year. Unfortunately, the Administrators are not able to give an accurate figure for the monthly number of Installers who left the scheme. This issue is due to the way data is received, as some installation companies which are listed as being removed are actually only suspended temporarily and then reinstated in the following months, therefore causing the data to be inaccurate.
