Warm Homes: Social Housing Fund
For councils and housing associations. The successor to SHDF, funding measures that bring social homes below EPC C up to C or above. Solar PV is an eligible measure, and SolShare makes it deliverable on flats, not just houses.

Warm Homes: Local Grant
Delivered through local authorities for low-income households in privately owned and rented homes, including solar. Relevant where a council's programme covers mixed-tenure blocks.

Why flats have been the hardest homes to get to EPC C

Fabric measures take a block so far. Many flats have no wall or loft to insulate further, and a heat pump per flat is rarely fundable.

Solar was the obvious next measure, but "one roof, one metre" made it impossible to give each flat its own system. SolShare changes that: one funded rooftop array, shared fairly across every flat, with a SAP credit for each home.

"One of our residents reported that her energy bill was £100 less than this same time last year. That's a serious result!"

"We installed just 3 inverters with 3 SolShares to serve 35 properties. If it wasn’t for Allume, we couldn’t have done it, there simply wasn’t space to fit 35 inverters."

“Many of our tenants at Scott Court have already reported noticeable savings on their energy costs, with some saying they’re topping up their pre-payment meters far less frequently. This is a real and tangible step forward in our mission to tackle fuel poverty."
