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.

In preparation for the launch of the domestic Renewable Heat Incentive (RHI) MCS has agreed with the Department of Energy and Climate Change (DECC) that all MCS compliant installations installed since 15th July 2009, but not yet registered on the MCS Installation Database (MID), must be registered on the MID by 4pm 22nd October 2013.

This year’s Edinburgh Fringe Festival is going green, by hosting a “Low Carbon Property Festival”. The event, which has been organised by a number of leading trade associations in Scotland, the FMB (Federation of Master Builders), the NSCC (National Specialists Contractors’ Council), SELECT (Scottish Electrical Federation) and SNIPEF (Scottish & Northern Ireland Plumbing Employers’ Federation), is aiming to raise the profile of low carbon building in Scotland.
