Energy pressure from July to October: what schools can infer: and plan for

Three different clocks

Energy coverage often places a current headline beside a historical statistic and a forecast. For a school, those are three different clocks. A headline describes an event or announcement; a statistic measures a defined period; a forecast estimates a possible future. Treating them as one continuous tariff series can lead to a confident but incorrect budget assumption.

The official September energy-price release covers April–June 2026. Its non-domestic electricity average was 24.51p per kilowatt-hour including the Climate Change Levy, 2% higher than a year earlier. ^[prices] That is useful context for institutional energy costs. It does not measure the change in school electricity tariffs between July and October.

October's domestic price-cap increase is another signal. Ofgem announced a 4% rise, with most of the increase driven by gas and domestic electricity bills broadly stable after the VAT change. ^[cap] Schools should not apply that headline percentage to their electricity budget. Its relevance is the continuing exposure of energy costs to wider market pressures.

Why schools experience the market differently

A school's bill reflects its agreement, renewal date, consumption and charging structure. A fixed arrangement can delay the effect of wholesale movements; a variable or managed approach may transmit them differently. Two schools with similar buildings can therefore face different financial changes during the same term.

The first task is to identify the institution's exposure. Record the contract end date, pricing mechanism, consumption assumptions and any provisions affecting onsite generation. Establish what happens next: a renewal, a purchasing decision, a review within an existing arrangement or no immediate change. That makes market news relevant to an actual leadership decision.

This is more useful than asking whether prices will simply rise. The board needs to know how a movement would reach its own budget and what options remain. A school approaching renewal may need a comparison now; another may benefit more from demand reduction and preparations for a later decision. The timetable belongs to the contract as well as the market.

What history teaches about a long agreement

The official non-domestic series records substantial price increases through 2021–2023 and a later peak in the average paid price than the immediate wholesale shock. ^[prices] The lesson is not that the same pattern will repeat. It is that market disruption and the prices institutions actually pay can move on different timescales.

A long-term solar agreement should therefore be tested against more than today's grid rate. The avoided cost could rise, fall or move unevenly. The PPA price may also change under its own mechanism. Leaders should ask how the relationship behaves under several plausible paths rather than extend the current difference unchanged for decades.

History also supports a broader energy strategy. Efficiency reduces the quantity of energy needed; suitable generation reduces some imports; good procurement manages the remaining purchases. Each has a role. The strongest school plan considers them together, recognising that solar does not replace every unit of electricity or remove gas demand automatically.

Forecasts are useful when boundaries are visible

A credible forecast states its publication date, market, horizon, assumptions and uncertainty. A near-term domestic forecast is not a twenty-year school electricity outlook. A forward price is a market price for a specified product at a specified time, not a guaranteed forecast of the school's delivered bill.

The programme now includes a comparable APXMIDP wholesale Market Index record from 1 July to 8 October. Available July observations average £106.24/MWh; the first eight October days average £148.68/MWh, 39.9% higher. ^[elexon] This is a short-term index comparison between different seasonal windows, not a school tariff increase. The electricity desk displays coverage, weekday daytime comparisons and downloadable calculations. A licensed forward-price feed remains unconnected; future school costs are tested with explicit scenarios rather than presented as a verified numerical forecast.

Leaders can use scenarios now. Test a lower-price path, a broadly flat path and a higher-price path. Apply them to the portion of electricity the school would still import and to the avoided cost of the onsite generation it can use. Compare that with the contractual PPA path. This turns uncertainty into a decision framework without pretending to eliminate it.

The useful role of solar under uncertainty

Solar's financial relevance is not limited to a prediction that grid prices rise forever. A suitable project may offer access to a different cost structure for some daytime electricity. The value depends on the actual price, usage, estate and obligations. Leaders should examine that proposition alongside the potential educational and environmental benefits.

The word 'some' matters. Schools still need electricity when the array is not generating enough. They may also retain significant heating demand. Budget protection should therefore be assessed at the whole-site level: what changes, what remains exposed and whether any additional obligations reduce flexibility elsewhere.

Storage can change timing, but it deserves its own assessment. A battery has costs, losses, degradation and operational requirements. It may improve the use of generation in some circumstances; it is not an automatic addition to every school project. Ask what specific problem it solves, what measured demand supports the case and how its benefit compares with the additional cost.

A practical autumn budget review

Start with the school's own records. Compare electricity use and effective costs over consistent periods, noting occupancy, weather-sensitive operations and tariff changes. Do not attribute every bill movement to market prices. If consumption fell, explain why; if price rose, identify the relevant contractual mechanism.

Next, prepare a manageable set of actions. Improve controls where there is evidence of avoidable use. Confirm renewal responsibilities and timing. Gather the records needed to assess generation. Put a solar opportunity on the estate plan where it fits, rather than allowing urgency around a market headline to bypass ordinary review.

Finally, give governors a short exposure statement. Explain what is known about current costs, what is uncertain about future costs and what the school is doing to reduce or manage that uncertainty. This is a constructive response to energy pressure: better evidence, suitable investment and clearer decisions. The programme will update the market layer when comparable sources justify a new claim, while retaining the dates and definitions of the evidence already published.

For a future market update, retain the observation period, publication date and product definition with every figure. A comparison needs the same market and charging basis at both ends. Leaders should also record the date of their own quotation, since a national series published later may describe an earlier period and cannot replace the actual purchasing choice.
