The government has launched the long awaited Future Homes Standard today (March 24). The majority of new homes will now be expected to be fitted with solar panels on roofs as standard, covering an area equivalent to 40% of the home's ground floor space. The Department for Energy Security and Net Zero (DESNZ) and the Ministry of Housing, Communities and Local Government (MHCLG) said they had "created a new functional requirement for the provision of renewable electricity generation".
