The city's diverse housing stock, including Victorian terraced houses, Edwardian bay-fronted homes, Modern waterfront developments, Council housing estates, Student accommodation, provides numerous opportunities for successful solar installations.
For the Warm Homes: Local Grant you apply through gov.uk. If your council has funding, it arranges a home survey and organises and pays for the work it agrees with you. Household income must usually be £36,000 a year or less and the home needs an EPC of D to G. This page does not list council schemes until each one is checked on the council's own website.
