Microgeneration Certification Scheme

Microgeneration Certification Scheme

The Microgeneration Certification Scheme (MCS) was introduced by the Department of Energy and Climate Change (now part of the Department for Business, Energy & Industrial Strategy (BEIS)) to help consumers and companies reduce energy consumption through the use of microgeneration technologies used to produce electricity and heat from renewable sources.

Green Homes Grant Scheme – due to launch September 2020

The Green Homes Grant scheme primarily supports households to increase the energy efficiency of their homes and to install low carbon heating systems. Homeowners are given vouchers of up to £5,000 to spend on energy-saving home improvements, with low-income households eligible for vouchers of up to £10,000.

Microgeneration Certification Scheme

To quality to install low carbon heating, such as air source or ground source heat pumps, and solar thermal systems under the Green Homes Grant Scheme, installers can join the APHC Microgeneration Certification Scheme.

The APHC Microgeneration Certification Scheme offers one of the most effective ways for heating installers to install heat pumps and solar thermal systems.

Green Homes Grant can be used in conjunction with Domestic RHI. In this scenario, the homeowner will first apply for a Green Homes Grant and then subsequently can also apply for RHI. The amount of their Grant is then taken off the value of their projected RHI payments.

Renewable Heat Incentive (RHI)


MCS is also linked to the Government’s Renewable Heat Incentive. MCS provides consumers with a guarantee that the products and installers they select meet the high standards to be eligible to receive a grant or financial incentive.

For plumbing and heating companies to install microgeneration technologies they must become certified MCS installers through a certification body such as APHC Certification Ltd.

Plumbing and heating companies will also need to become a member of a Consumer Code, either the Renewable Energy Consumer Code (RECC), The Home Insulation & Energy Systems Contractors Scheme (HIES) or the Glass and Glazing Federation (GGF) to ensure your customers are protected by a Trading Standards Institute (TSI) Approved Code of Practice.

Plumbing and heating companies can join the scheme provided they meet the scheme requirements as outlined in the scheme documents, available to download below.

Following completion of the initial application form, the assessment process comprises of:

1. Desktop evaluation of the company management system. This part is a pre-check to confirm company readiness for its assessment under the scheme. Information on company procedures is provided to APHC Certification Ltd. for a desktop evaluation which takes place at our premises.

2. Head office assessment of the management system. This part of the process assesses the use and application of the company management system against the MCS001 standards at the applicant company’s business or home office.

3. On-site assessment of installed work areas. This part assesses competence to install each of the technical work areas against the MIS 3001 (for solar heating), MIS 3004 (for woody biomass) and MIS 3005 (for heat pumps) standards that form the company’s application under the scheme. The company will need to show one example of an installation for each work area it wishes to be certified to install.

Once approved, companies will be registered with the Microgeneration Certification Scheme (www.mcscertified.com)* and then have the ability to install and certify a range of permitted microgeneration work areas.

*Please note that there is an annual registration fee for this which APHC Certification Ltd. will collect on behalf of the Government MCS License Holder.

Scope of work areas:

• Woody Biomass Boilers
• Ground and Air Source Heat Pumps
• Solar Thermal Hot Water Systems

As part of MCS arrangements, installers are required to ensure that Building Regulation requirements are fully complied with so in addition, companies can join the Competent Persons Scheme.
