Why group / multi-site corps solar works on SPEN

Group / multi-site corps in the SPEN territory share three structural advantages for solar PV programmes:

  1. Sub-vertical fit. Multi-site group corporations operate 3-15 campuses under a single corporation board, enabling a single funding application where a scheme allows it, consolidated procurement, and phased delivery across multiple summer windows.
  2. DNO characteristics. SP Energy Networks covers central and southern Scotland. Check its published connection guidance and network capacity information before sizing the array.
  3. Funding routes to check. Status verified 20 October 2026: Salix has no scheme open for England, the Scottish and Welsh Salix loans are open, and PSDS Phase 4 is closed to new applications. The Scottish Public Sector Energy Efficiency Loan Scheme (Salix) is open in 2026; check Scottish Government and Scottish Funding Council capital routes with your SFC contact.

Tell us about your institution and we reply by email with the funding routes that look relevant for your nation (Salix loans in Scotland and Wales, mayoral and combined-authority schemes, Great British Energy, DfE capital, self-funded or PPA routes) and an indicative system size worked from your electricity spend. It is a desk exercise from what you send, so no site visit is needed to start.

What we won't do: add you to marketing lists or share your details without asking you first.

Why we ask what we ask: your spend and postcode set the indicative system size and which regional schemes apply, and the building and timeline tell us what to look at first. Reviewed by SEO Dons Editorial. We are an independent advisory, not an installer.
