The Environment Agency offers subsidies for upgrades that improve energy efficiency or allow for the use of renewable energy. This public financial assistance programme is particularly geared towards energy upgrades to existing residences.
The State grants a kind of financial assistance called "PRIMe House" to carry out energy upgrades to existing residences that are over 10 years old at the time the application is submitted.
