MCS Accredited

What is MCS and what does it mean to be an MCS accredited installer?

MCS stands for Microgeneration Certification Scheme. The Microgeneration Certification Scheme was set up in 2008 to certify microgeneration products and installers in accordance with a set of quality standards. The Scheme was designed to provide a level of protection to consumers and the assurance that both product and installer have met a high minimum standard which has been assessed by an independent MCS Certification body.

The MCS scheme covers the following technologies:

  • Wind Energy
  • Small Scale Hydro
  • Solar Thermal (Hot Water)
  • Ground Source Heat Pumps
  • Air Source Heat Pumps
  • Biomass
  • Solar Photovoltaics (PV)
  • Micro-CHP (Micro Combined Heat and Power)

When you install one of the above technologies, your installer will provide you with an MCS Certificate.  This has a unique certificate number for your installation and confirms that your installation uses compliant products and has been installed by a certified installer.  This certificate is important as it gives you access to government incentives such as the Feed-in Tariff, Renewable Heat Incentive (RHI) and coming soon, the Green Deal.

What does it mean for installation companies?

The MCS standards cover 3 key aspects required to deliver a compliant installation:

  • The installation company must have the skills, knowledge and practical competence to supply, design (or evaluate a design), install and commission and hand over the technology for which they are seeking approval.
  • The installation company must follow good working practices for consumer protection, involving compliance with a Consumer Code of Practice which must meet the guidelines set by the Office of Fair Trading (OFT) Consumer Code Approval Scheme.  Morgans Solar is an approved member of RECC.
  • The installation company must have an appropriate management system for controlling quoting, purchasing, invoicing, complaints management, quality checking and record keeping.


Approval is achieved by undergoing an office assessment and an on-site assessment (covering each technology type) to ensure that each of the above elements is met as detailed in the published standards (which are all available on During the assessment the certification body, in our case NAPIT, will also seek to gather evidence of compliance with the Building Regulations to allow approval for self-certification.

The assessments may result in corrective actions being set, but once all items have been resolved approval can be granted.


Once an installation company is approved they will be required to continue following the rules of the scheme and will enter a surveillance programme appropriate to the scope of their approval which will monitor the ongoing compliance.

Certification and Listing

Approved installers will be issued with a certificate of approval detailing which technologies they can install and they will be listed on the scheme website.   This listing enables energy users to identify competent, reliable installation companies so they have confidence that installations will perform properly and be eligible for financial incentives.
