Microgeneration Certificate Scheme (MCS)

MCS Logo

This scheme will demonstrate you or your employees competence to install a range of small scale renewable and low carbon technologies in both the domestic and commercial sectors.

For your customers to qualify for Government incentives such as the Renewable Heat Incentive (RHI) and the Feed-in Tariff (FiT), an installation must be compliant with MCS standards and have been installed by an MCS Approved Installer.

Scheme Details

Geographical Scope – United Kingdom
Approval - UKAS accredited

Scheme Requirements

The following general conditions must be met:

Relevant Standards - MCS Installer Standards. There are also Engineering Recommendations to meet for grid connections (for exporting electricity). These are available on the MCS Installer Standards page of the MCS website.

Legal Requirements - There are a wide range of regulatory requirements relating to microgeneration work, including planning, environmental and Building Regulations specific to the UK region where the installation takes place. More information can be found on the MCS website.

Qualifications - The competence requirements for MCS are covered by compliance with the standard MCS025. This includes the experienced worker route (see Page 7).

Insurance - Chartered Trading Standards Institute (CTSI) approved consumer code schemes require members to have suitable liability insurance and to provide insurance-backed workmanship warranty for all consumer work.

Consumer Code Scheme - In order to provide consumer confidence, it is a requirement that installers be a member of Trading Standards Institute (TSI) approved Consumer Code Scheme.

Instruments - You or your employees must have access to sufficient instruments to carry out tests relevant to your scope of work as well as an in date calibration certificate for you or your employees equipment where applicable.

Technical Reference Documents - You or your employees must hold some, and have access to other, documents relevant to the type of work carried out, all of which are detailed on the MCS website.

Inspection -You or your employees will need to demonstrate that you have the policies, procedures and records are in place to meet the requirements of MCS 001 Appendix A. You or your employees must also make available an installation which demonstrates the ability to undertake the supply, design and installation, set to work, commissioning and handover of the system in compliance with the relevant Microgeneration Installation Standard.

Notification - In England and Wales, Building Regulations self-certification must be carried out by notifying NAPIT within 21 days of completion of an installation, a Building Regulations Compliance Certificate will be issued to cover the work and the relevant Local Authority will be automatically updated. All MCS work must also be registered on the MCS Installation Database within 10 days of commissioning a system (this is not a NAPIT system and must be accessed separately).

Website Listing - Once successfully certified, your business will be added to the MCS Installer search facility as well as the NAPIT online search facility.

How MCS relates to CPS

MCS Approval with NAPIT can allow you or your employees to self-certify the microgeneration installation work completed without any further scheme fees or assessment. However, additional fees and assessment do apply if scheme work extends beyond the installation of microgeneration technologies (such as new circuits or hot water storage etc).

How MCS relates to EES

To carry out renewables work on energy efficiency programmes (such as Eco) you do not need EES registration because compliance with the MCS standard MCS 023 is accepted as equivalent to PAS2030.
