In line with the MCS standards, an MCS certified contractor must comply with the Customer Commitment.

The two approved consumer codes currently recognised by MCS are:

• Renewable Energy Consumer Code (RECC)
• The Home Insulation & Energy Systems Quality Assured Contractors Scheme (HIES)

Key issues covered by the Customer Commitment include:

• customers in vulnerable circumstances
• advertising
• behaviour of sales reps
• performance information
• proposals
• costs and quotes
• contracts
• cancellation rights
• amount of deposit permitted
• guarantees
• maintenance
• dispute resolution process

A MCS certified contractor may also be a member of a CTSI Consumer Code, however this is no longer a requirement under the new redeveloped MCS scheme. The two approved consumer codes currently recognised by MCS are:

• Renewable Energy Consumer Code (RECC)
• The Home Insulation & Energy Systems Quality Assured Contractors Scheme (HIES)’
