Householders interested in applying for Low Carbon Buildings Programme grants were required to use certified installers and products. Under the Renewable Heat Premium Payment (RHPP) scheme, which replaced the Low Carbon Buildings Programme in 2011, homeowners may be eligible for cash vouchers if they have installed certain microgeneration technologies.
In order to qualify for vouchers under the RHPP scheme (and the upcoming Renewable Heat Incentive for homeowners), both the product and the installer must be MCS certified. Products and installers with equivalent certifications are also eligible for RHPP.
The Microgeneration Certification Scheme has an online installer and product search engine, which allows you to search for certified microgeneration technologies and installers in your region. Householders can request vouchers under the RHPP in advance of installing microgeneration technology in their homes. Vouchers for solar thermal systems must be used within three months of receipt, while vouchers for other microgeneration technology are valid for up to six months.
