Accreditation associated with Heat Pumps

The main UK quality assurance scheme for low-carbon and renewable energy technologies is the DECC-supported Microgeneration Certification Scheme (MCS). It is through MCS that heat pump systems must be registered in order to be eligible for the RHPP grant and RHI payments. Your installer should help you with this process, and before installation should advise you of the proposed installation’s eligibility for financial incentives.

It is therefore essential to ensure that your installer/supplier is accredited by an MCS-appointed certification body. MCS-accredited companies must conform to rigorous quality and safety standards and meet Office of Fair Trading (OFT) requirements.

It is necessary to ensure that the heat pumps system that you plan to install is MCS-certified, which means that it has been subjected to testing and rigorous quality controls.

A database of MCS-certified products is available in our technology database (link) and on their website:

MCS also have an industry Code of Practice and can investigate complaints on behalf of consumers.

Reputable renewable energy installation companies should also be a member of Renewable Energy Assurance Ltd (REAL). Membership of REAL indicates that a company has signed up to its OFT-approved Consumer Code, which ensures high service standards before, during and after the installation of renewable energy technology. Any sub-contractors engaged by installation companies must also comply with the REAL codes of practice.

Details of the code of practice and a list of REAL scheme member companies can be found on their website:

There are also industry bodies, such as the Ground Source Heat Pump Association, which encourages high installation standards and promotes the efficient and sustainable use of heat pump technology. See their website at:
