A financing question with a near-term checkpoint
Great British Energy, supported by the Green Finance Institute, is seeking investor views on potential financing structures for portfolios of local clean-energy projects. Published on 7 October, the exercise explores bringing smaller public-sector solar and storage projects together at a scale attractive to institutional investment. Responses are requested by 23:59 on 30 October 2026. [gbeportfolio]
The deadline is an investor-engagement checkpoint. GBE explicitly describes preliminary market engagement and says it creates no expectation of investment. It is not a school application deadline, a funding award or an announcement that DfE PPA approvals have reopened. Its value to this programme is the practical question it raises: could a responsible body describe several candidate sites well enough for a serious portfolio assessment?
Our earlier trust feature explained why organising sites together could matter. This continuation examines the preparation behind that proposition. A list of schools and roof areas is a useful starting inventory. An investable proposition requires stronger evidence about demand, building condition, authority, delivery dependencies and the allocation of risk.
Define the portfolio before describing its scale
Start by identifying who is organising the assessment and which institutions are actually within its scope. A trust's operational estate may contain different ownership interests, leases and responsibilities. A local authority may coordinate opportunities without every school being able to follow the same contractual route. Establish these differences before presenting a combined project.
Give each site a stable identifier and link it to the relevant responsible body, buildings and electricity supplies. Record whether the site has expressed interest, supplied evidence or authorised assessment. These stages should remain visible. Counting an interested school as a committed participant would make both the scale and the delivery timetable less reliable.
The useful leadership output is an agreed candidate register with a clear boundary. It should show what is included, what remains conditional and who can change the scope. This gives advisers and potential funders a consistent starting point and allows schools to understand the decisions being considered on their behalf.
Standardise the evidence without flattening the differences
A common evidence template makes comparisons easier, but the underlying schools will still differ. Record roof condition, remaining life, planned works, access limitations and the status of technical investigations. Identify whether existing equipment or building changes affect the usable surface. Keep the date and limitations of each source attached to the finding.
Alongside the estate record, retain each site's meter information and consumption profile. Teaching-only accommodation, swimming facilities, kitchens and extensive community use can produce different patterns. A portfolio average may conceal a site that needs a different system size or cannot use much generation during school holidays. Preserve the individual profile before considering the combined result.
Maintain an evidence-status field for each item: verified, reported, estimated or unresolved. State the owner and next action for a gap. The purpose is to improve the quality of the assessment, not to create an impressive score from incomplete records. Unknown structural capacity remains unknown even when the roof area is accurately mapped.
Use settlement reform to improve the data discussion
The MHHS programme schedules supplier-readiness Milestone 14 for 28 October. It concerns suppliers' ability to operate under the new arrangements. Full migration is scheduled for 7 May 2027, followed by the settlement-timetable transition on 2 July. These are separate milestones; a school should confirm its own position with its supplier. [mhhsreview]
For a portfolio coordinator, the immediate action is to request consistent half-hourly data and record what is available for each MPAN. Ask about access permissions, migration status, metering arrangements and any proposed contractual changes. The scheduled industry milestone does not establish a new tariff or guarantee that the school already has usable historical data.
Build the analysis around matched dates and explicit coverage. Identify missing intervals, changes of meter or supplier and unusual operating periods. Explain how the proposed generation profile would be compared with consumption. Better data can improve the basis for assessment, but it cannot remove the need for competent design or establish a particular saving on its own.
Test whether grouping creates value
GBE's engagement asks about matters including portfolio scale, contractual arrangements and risk allocation. [gbeportfolio] School leaders should translate that into questions they can scrutinise. What work could be coordinated? Which costs remain site-specific? Does a combined timetable fit the schools' condition works and operational requirements? How will responsibilities be allocated if one site is delayed?
Request a transparent explanation of any claimed portfolio advantage. Shared assessment or procurement might reduce duplication, but different roofs, permissions and electrical arrangements can create additional work. Compare the proposed approach with credible alternatives and identify which benefits depend on achieving a minimum scale. Treat those conditions as part of the decision.
For smaller schools, inclusion could be valuable if an organised approach makes assessment or delivery more practical. That possibility needs evidence. Ask how participants are selected, how costs and benefits are allocated and whether a weaker site could create obligations for others. A consistent method should help leaders understand differences rather than conceal them in a single attractive headline.
Keep import contracts and solar obligations in view
A portfolio assessment needs to show what happens to each school's existing electricity arrangements. Record renewal dates, notice requirements and the treatment of network and balancing costs. Solar generation consumed onsite can reduce imports, but the appraisal must identify the costs that actually change and the responsibilities that remain.
Ofgem's 22 October decision retains 15 months' notice for distribution charges in the first year of the next price-control period and sets 14 months for the second year. That period begins in April 2028. This is a decision about notice, not evidence that network charges will fall. [ednotice]
Use the publication timetable to improve the questions asked about longer import contracts. Which charges are fixed, passed through or subject to later adjustment? For the proposed solar agreement, examine escalation, export arrangements, purchase obligations and adverse demand scenarios. A combined portfolio should remain understandable at the level of the school that ultimately carries the obligation.
Separate preparation from permission
The DfE pilot guidance remains the controlling published reference for its template and approval position. Our review on 27 October did not verify final approved templates or resumed approvals. The GBE financing exercise does not alter that boundary. [pilotcurrent]
Responsible bodies can still organise records, identify suitable professional investigations and establish the authority required for the next stage. Record every material dependency, including roof works, property consent, procurement, connection assessment and the status of the proposed agreement. Give each one an owner and a review point rather than hiding it behind an overall completion date.
The recommended next output is a portfolio preparation pack with site records, a shared assumptions register and a short decision summary. Distinguish sites ready for further assessment from those needing works or evidence first. This gives school leaders a constructive next step while the financing market develops: better organised choices, clearer responsibilities and a stronger basis for deciding whether a future proposal serves education.
Put the feature to work
Your next leadership discussion
- Trust or LA coordinator: define the candidate estate and each site’s authority to participate.
- Finance: request MPAN-specific interval data, contract dates and retained-cost information.
- Estates: standardise roof evidence while keeping site-specific constraints visible.
- Track the 30 October investor-engagement deadline separately from school funding and DfE approvals.
Questions to resolve
- Can every site in the proposed portfolio be traced to current demand, roof and authority evidence?
- Which claimed benefits depend on scale, and how would costs and risks be allocated?
