Start with the next operating year

Last year’s meter total is a useful starting point. It cannot describe every change the school is planning. A nursery extension, different boarding pattern or revised holiday programme can alter when and where energy is needed. A planned reduction in occupied space may leave standing loads elsewhere untouched. The buying brief needs to connect these practical facts with the agreement being considered.

Take a fictional school planning to consolidate two teaching buildings. The school may expect lower annual use, but still needs both buildings heated during a transition. It could also face a charge for removing a supply point. A comparison based only on the eventual lower consumption could miss costs in the first year and obligations later in the term. The example is a planning prompt, not a prediction about an actual school.

A climate action plan can give this discussion a useful starting point. It can also create a misleading forecast if an intended project is treated as certain before its funding, approval or delivery date is settled. For the bursar, the task is to bring the project owner’s evidence into the buying decision while keeping the capital commitment and the supply commitment visible to the people authorised to approve each.

DfE’s climate-action-plan guidance was updated on 3 November 2026. It remains non-statutory England guidance; the update added further-education links, support contacts, case studies and a newsletter rather than a new school energy-buying deadline. An independent school can use the planning connection through its own governance, with the appropriate national scope. The practical next step is one agreed forecast and a clear account of what would change the recommendation.

Recognise the operating model before discussing the product

The independent sector contains small day and prep schools, mixed campuses, boarding provision and groups with several legal entities. Within ISC’s 2026 membership survey, 1,032 schools were day schools and 423 had boarders. A programme centred only on a large residential campus would miss much of that population.

Build an operating calendar for the school concerned. Record the teaching day, extended care, catering, cleaning, sport, holiday occupation and any residential use. Include a pool or commercial letting when it exists. A shared meter can hide different activities, so distinguish what is measured from what is estimated and record the allocation method. This makes the data more useful to a supplier and to the people managing the building.

Separate the decisions that product labels combine

Ask the adviser or supplier to explain five things separately: which charges are fixed, the supply period, how purchases are made, the volume or site obligations, and who can make decisions. A fixed commodity rate does not by itself explain the treatment of every other charge. A managed basket needs a clear account of purchasing rules, allocation, entry and exit.

Flexible purchasing also needs an operating discipline the school can sustain. Establish who may authorise a purchase, the agreed limits and how remaining exposure is reported. Request an explanation of the position already bought and the position still open. If the school is paying for that management, the service and reporting should appear in the requirement and the cost assessment.

Our recommendation is to use the offered terms as the evidence. Ask for a charge schedule and a plain-language explanation of the provisions that can change cost. Retain the contract wording beside the explanation, with any qualifications or unresolved legal questions visible.

Give the duration a reason

Twelve, twenty-four or thirty-six months are periods to assess against the school’s plans. Where forty-eight to sixty months is offered, the school needs an equally credible view of the longer commitment. These are possible comparison periods, not a list of available offers or recommended terms.

An earlier review may suit a defined transition, but creates another buying exercise and uncertainty about later conditions. A longer agreement may assist planning for specified charges, while leaving the school committed through changes in use or ownership. Explain which benefit matters to this school and which risks it accepts in exchange.

Calculate any adviser uplift over the complete proposed period using a stated consumption assumption. Keep direct fees and services outside the supply price visible, without adding an embedded uplift twice. Compare the whole period and identify the charges that remain uncertain; an annual average can conceal a difficult payment or adjustment in a particular year.

Ask about the changes before they happen

A school group should identify which entity will be the customer, which sites are included and who can bind each buyer. A trading subsidiary, residential property or newly acquired campus should not be assumed to sit within the same agreement. The ISBA’s description of bursar responsibilities includes staff accommodation, lettings and estate management, illustrating why the contract boundary can extend beyond the teaching timetable.

Ask how the proposed terms address adding or removing sites, transferring the contracting entity, substantial changes in demand and early termination. Obtain the supplier’s written response and identify any consent, repricing or financial consequence. A description such as “flexible for growth” needs to be translated into the actual provision and any discretion the supplier retains.

Test a less convenient version of the plan

Use at least one clearly labelled adverse scenario that is relevant to the proposed agreement. It might involve a delayed building closure, lower occupation or a planned increase that does not materialise. Change the consumption and relevant charges consistently, keeping assumptions visible. Do not treat missing contractual information as a zero cost.

The purpose is to discover what could change the decision. If two offers appear close in the central comparison but behave differently when demand changes, explain that difference to the authorised reviewers. Some consequences need professional judgement or a supplier clarification rather than another spreadsheet formula. Give those questions an owner and a deadline before acceptance.

For a heating conversion or on-site generation proposal, test the delivery window as well as the eventual annual use. A delay may leave the school buying its existing requirement for longer; a transition can create a different mix of fuel and electricity. Ask the supplier how the actual clauses treat those cases, then return any continuing charges or adjustment costs to the project appraisal. The better option depends on the school’s written offers and supported plans.

Leave the estates team with a usable agreement

ISBA’s operational carbon guidance includes different representative pathways for rural boarding and city day-school estates. They are illustrative pathways, not achieved savings. Their practical relevance here is that the operating requirement should be understood before a long commitment is evaluated.

Bring finance and estates together around one dated brief. Have the school approve the forecast used for comparison, record credible future changes and preserve the final terms. The decision should explain how the agreement will be managed if those assumptions move. Use the changing-demand guide to prepare the questions, then take the written answers into the bursar’s recommendation.
