It aims to guarantee a high quality experience for consumers wishing to buy or lease small generation units for their home, for a community building or for a small business. REAL membership is a sign that the supplier has agreed to obide by the high standards set out in their consumer code. The REAL logo is a symbol of professional excellence.

The Microgeneration Certification scheme (MCS) is an independent certification scheme designed to certify microgeneration products and installers in accordance with consistent standards. The scheme was launched by the Department for Business, Enterprise and Regualtory Reform.

The MCS mark guarantees that the installer follows a code of practice that meets the guidelines set by the Office of Fair Trading Consumer Code Approval Scheme
