How can SolShare future-proof your developments?
SolShare future-proofs developments by ensuring every apartment complies with the 2026 Future Homes Standard.
As UK building regulations shift toward total decarbonisation, solar for flats is now a core requirement for SAP 10.2 and Part L compliance.
By sharing one rooftop array across all units, SolShare eliminates one roof, one meter barriers, offering buyers and renters tangible energy bill savings; a high value USP that increases property marketability in a competitive private rental and sales market.
The smarter way to deliver solar in apartment buildings
SolShare is the world’s only technology to connect a single rooftop PV system amongst multiple dwellings within the same building, making solar for flats simple, scalable and cost-effective.
Achieve up to 20 SAP points per flat
SolShare is classified as a direct solar PV connection for flats. This qualifies for the maximum points under SAP 10.2.

Proven benefits for developers
Custom solar allocation per flat
It allows you to allocate specific amounts of solar energy to each individual flat according to its specific needs.
Reach EPC targets faster
It allows you to allocate specific amounts of solar energy to each individual flat according to its specific needs. An efficient and cost-effective route to achieving EPC A targets in multi-unit developments.
Cost-effective
As little as £200 per SAP point. One of the most cost-effective methods for achieving EPC targets.

6+ Flats
Scalable solution.
6+ Flats
Suitable for low and medium-rise apartment buildings.
Saves time, money & space
Simple to design & install, lower compliance and no hardware inside the flat.

Futureproofs for upcoming SAP changes
As SAP regulations evolve, SolShare lets you allocate specific solar capacity (kWp) to individual flats
Futureproofs for upcoming SAP changes
This allows you to easily fine-tune the system, directing more solar to the exact apartments that need the biggest SAP or EPC boost.
Real-world results
"SolShare got us out of the serious problem that we found ourselves in just three weeks before hand over. Without SolShare boosting the flats by 1 SAP point we would have been having some very difficult conversations.”
Project Manager, UK
“Scott Court is more than just a retrofit; it’s a blueprint for the future of socially responsible, sustainable housing.”
David Conway, Head of Asset Management, Hillcrest, Scotland
“It’s not just about putting shiny new things on a building, but the fact that they improve that person’s life."
Malcolm Davies, Welsh Government, Wales
“One of our residents reported that her energy bill was £100 less than this same time last year. That's a serious result!””
Tania Jennings, Net Zero Climate Manager, Climate Resilience, Lewisham Council, London

Ideal for M&E consultants looking to futureproof projects and meet net zero goals.
Testimonials
“As a developer, we are proud to be bringing such a progressive scheme to the market. We have proactively worked with the various elements to bring the best technology to the scheme, and we’re thrilled with the results.”
“The SolShare system seems to be a much fairer solution as the energy generated by the building can be shared equally to help our residents to keep their electricity costs down rather than going back to the grid.”
“This is an exciting first-of-its-kind project for Wales and exactly the type of thinking we need to see within the housing sector.”
“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 simplywasn’t space to fit 35 inverters."
