School solar in October: the funding route matters as much as the roof

October brings a checkpoint, not a new starting gun

The next useful school solar decision begins with a careful reading of the record. In a parliamentary answer on 13 October, DfE reiterated 245 completed grant-funded installations and an estimated £220 million in lifetime energy-bill savings. These are not newly announced October totals: both figures appeared in July. The answer also restated plans for around 100 further grant-funded sites through Renewal and Retrofit, subject to suitability and feasibility. ^{[parliament] [july]}

That distinction matters. A recent ministerial answer provides a dated checkpoint, but repeating an existing total does not demonstrate additional installations since the last announcement. Nor does a lifetime estimate establish savings already received. Our assessment is that this is a useful continuation of the programme, rather than evidence that the separate PPA pilot has completed its next approval milestone.

For leaders, the opportunity remains worth pursuing. The practical advance is to move from a broad question about getting panels to a specific question about the right route for the site. That means identifying who pays, what the school undertakes, how the project fits planned works and which decision can properly be taken now.

Separate the funding routes before comparing the benefits

A grant-funded installation and a privately financed PPA can produce electricity from similar equipment while creating different financial responsibilities. The first question in any proposal should therefore be the funding route. Ask for that answer in writing, together with the institution's eligibility or invitation status and the documents supporting it.

Under a PPA, access to generation comes with a purchase arrangement and associated responsibilities. DfE's published guidance describes sector testing of its PPA and land-lease templates, with new approvals paused until templates are published. Rechecking that guidance on 19 October did not establish a published final template or confirmed resumption. The autumn expectation remains an expectation; wider access in 2027/28 remains an ambition. ^{[pilotreview]}

A school should distinguish an invitation to discuss feasibility, a place in a programme, a technically suitable project and an authorised agreement. They are different stages. A preparatory conversation can be valuable without carrying permission to sign. Finance and estates colleagues should use the same description of the stage reached so that a promising enquiry does not become an assumed commitment.

Put solar into the building plan

The October answer explicitly places solar alongside wider renewal and retrofit, including possible replacement of life-expired temporary buildings. ^[parliament] Our practical recommendation is to turn that relationship into a site sequencing exercise. A roof is part of a changing estate; its best use depends on the building beneath it and the works already planned.

Begin with a single drawing or site schedule showing candidate roofs, known condition issues, planned replacements, likely changes in occupation and existing electrical infrastructure. Mark which information is supported by a survey and which remains an assumption. This need not become a large new strategy document. Its value is making conflicts visible before design choices become expensive to change.

Then ask whether a proposed installation would help or obstruct the next estate decision. If a building may be replaced, the case for installing equipment now needs to explain that dependency. If several works are being planned, investigate coordination of access and disruption. Do not book benefits from combined delivery until the scope and costs support them.

Recalculate demand after the changes you already intend to make

The sensible solar case starts with the electricity the school expects to use when the project operates. An old annual bill is a useful record, but it cannot describe the effect of changing lighting, removing temporary accommodation, extending opening hours or altering heating. Demand preparation should record those intended changes explicitly.

Ask finance and estates to reconcile the baseline meter data with the actual site. Record the period covered, school holidays, exceptional closures and whether all relevant buildings are included. Keep a separate line for each planned intervention that could change consumption. The objective is a coherent account of future demand, with uncertainty visible.

For a trust, resist averaging away the differences between schools. A teaching-only site and one with extensive evening or holiday use may use solar generation differently. Compare candidates on a consistent basis while retaining their individual profiles. Our school-day electricity analysis and appraisal guide provide the next level of detail; a national rollout headline cannot perform this site-level work.

Keep winter pressure and a long agreement on different clocks

Rising winter use can make the solar conversation feel urgent. It should also sharpen the questions. A decision extending over many years needs to remain workable across changes in consumption, retail contracts and electricity prices. A short run of observed wholesale prices is context for that assessment, not a quotation for the school's next contract.

Use the live electricity desk to understand the dated observations and their coverage. Use the school's bills and actual renewal quotations to assess its delivered costs. Use clearly labelled scenarios to explore what would happen under different future paths. Those three records should remain identifiable in the board paper, with assumptions and dates attached.

Meanwhile, contract reviews, controls and consumption checks can proceed on their own timetable. The separate winter energy feature sets out that immediate work. Schools should not postpone a necessary renewal or an operational improvement while waiting for a solar route to develop. Equally, a difficult renewal should not justify accepting a long solar commitment before its full obligations are understood.

Make the next approval request smaller and clearer

The next board paper need not ask for a final installation decision. It can seek authority for a defined investigation: confirming the route, resolving a building dependency or obtaining the evidence required for a formal appraisal. State the cost of that work, who owns it and what the resulting decision will be.

Finance should lead the reconciliation of costs, consumption and purchase obligations. Estates should lead the building sequence, condition evidence and operational dependencies. Governors or trustees should check that the requested authority matches the stage reached, with unresolved matters recorded rather than buried in an optimistic summary.

Give the investigation an end point. A useful output is a brief option record showing which sites can progress to assessment, which require works or evidence first and which should be reviewed later. Attach the reason for each classification. This creates progress leaders can scrutinise without pretending that every interested roof is already a viable project.

What would justify the next programme update

We have not verified a new final-template publication, an approval-reopening announcement or a published market-engagement outcome in this review. That is a statement about the evidence located, not proof that no work is taking place. The next change in this programme should explain the actual document and the school decision it affects.

For now, the constructive response is to identify the funding route, align the project with the estate plan and commission the missing assessment. Preserve the earlier briefings as the historical record, use this checkpoint as the current interpretation and return when a verified development changes what schools can do. The ambition is substantial: a lasting educational benefit supported by a decision that remains understandable after installation.
