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 has published a consultation on the MCS Certification Body Requirements Document. The Certification Body Requirements Document is accompanied by a detailed Impact Assessment covering the clauses applicable to MCS Contractor Certification Bodies.

The deadline for responses is Friday 4th December 2015. Further information and all relevant documents can be found on the consultations page of the MCS website.

MCS has released a new heat pump calculator which is available to download from the MCS website – link here.

A new version of MCS 012 (Product Certification Scheme Requirements - Pitched Roof Installation Kits - Issue 2.0) has now been published and will become mandatory from 2nd May 2016. Key updates include the compliance with regulations relating to external spread of flame when installing in-roof solar panels. All MCS certified installation companies who are installing in line with the requirements of MIS 3001 and MIS 3002 should refer to MCS 012.

Please read the ‘MCS 012 Fire Performance of Pitched Roof Mounted Solar’ document for more details.

The Microgeneration Certification Scheme (MCS) will be releasing a change to the MCS Installation Database (MID) on Thursday 5th November.

From 5th November, when you create a MCS Certification you will be asked to clarify whether the installation is domestic or non-domestic, and provide further details regarding the insurance warranty provider and insurance policy if applicable.

Last Thursday (1st October 2015), two important pieces of consumer legislation came into force. They are: the Consumer Rights Act 2015 and the Alternative Dispute Resolution for Consumer Disputes (Competent Authorities and Information) Regulations 2015.

These new laws will affect business to consumer contracts in the small-scale renewable generation sector.

The Renewable Energy Consumer Code (RECC) have summarised the information around the two legislations. You are able to access this information by visiting their website

They  have also created a guidance document for their members.

The MCS Installation Database (MID) will be undergoing maintenance and will not be accessible between 20:00-22:00 on Monday 5th October. Please do not try to access the database during this time as you will be unable to generate certificates and it is unlikely that any MCS certificates will be sent out.

The MCS Installation Database (MID) will also be undergoing further maintenance on Saturday 31st October and will be down for approximately 2 hours. We will place a further update regarding this maintenance on the News & Events section of the website nearer the time.

The Microgeneration Certification Scheme (MCS) has today launched a revised layout of the MCS website, which we hope will ensure our users have a better experience when navigating through the website.

The changes to the website include:

  • A general revision to the layout. You will note that there are now individual pages for technology specific installation and products standards which we hope will make it easier to locate relevant documents;
  • A new “submit an enquiry” function has been added which allows consumers to submit enquiries directly to MCS certified installers by completing an online form. The enquiries will be sent to the email address that you have registered with MCS.

The Microgeneration Certification Scheme has published MCS 007 Issue 5.0.

The update includes:

MCS 007 clause 8.1.4:

‘Evidence in accordance with MCS 011 shall be provided of actual testing of products at a relevant test point preferably selected from those defined in Table 2a.

However, providing the heat pump has achieved MCS certification on or before 25th September 2015, evidence in accordance with MCS 011 using test points detailed in Table 2b shall be used if those in Table 2a are not available.’
