Did the energy decision work? A care-provider guide to measuring the outcome

Decide what success means before counting it

A care provider may see a lower bill after an energy review and reasonably ask whether the decision worked. The answer depends on what changed. A lower rate, milder weather, fewer occupied rooms, a corrected invoice and reduced consumption are different explanations. Each can matter financially. They should not be added together without checking their boundaries.

This guide proposes a practical outcome review for finance and estates teams. It can be used with an energy broker, building adviser or internal project lead. It is not a promise of savings and does not replace specialist measurement where the investment or uncertainty requires it. The aim is a defensible account of what happened, what can reasonably be attributed to the decision and what should happen next.

Preserve the original decision record

Start with the approved purpose. Was the organisation seeking budget certainty, a competitive renewal, a billing correction or lower energy consumption? A fixed contract selected to make expenditure more predictable should be assessed against that objective. A later market fall does not by itself prove the original decision was unreasonable, just as a later rise does not prove every aspect of the service was successful.

Retain the offers available at the time, their validity dates, assumed consumption, included charges and approval record. An actual contemporaneous alternative is stronger comparison evidence than a price obtained months later. Where no credible alternative was retained, say so. Compare against the documented budget if useful, but label that as a budget variance rather than verified procurement savings.

Ofgem’s good-practice guidance provides context for clear intermediary roles and remuneration. Our proposed extension is to agree the outcome measures and evidence before appointment, so both parties understand how value will be reviewed. This is a management method, not a claim that the guidance mandates our precise calculation. ^[1]

A fictional example: separate price and consumption

Consider an invented annual electricity example for one care property. It is a calculation exercise, not a quotation, benchmark or result achieved by a provider. Assume a credible reference offer of 30p per kWh and a selected offer of 28p per kWh, both with a £1,200 annual standing charge. Hold all other charge boundaries equal and exclude VAT, Climate Change Levy and other taxes or levies throughout this simplified comparison.

At the original forecast of 200,000 kWh, the reference cost is £61,200: £60,000 for units plus £1,200 standing charge. The selected cost is £57,200: £56,000 plus £1,200. The projected procurement difference is therefore £4,000. If there is a separate £1,000 annual advisory fee not already included in the selected offer, the projected difference after that fee is £3,000. Embedded remuneration must not be deducted a second time.

Now assume actual consumption is 190,000 kWh. At the selected rate, the simplified actual cost is £54,400, consisting of £53,200 for units and £1,200 standing charge. Adding the separate fee makes £55,400. Comparing that with the original £61,200 reference forecast produces a £5,800 difference. Calling all £5,800 a procurement saving would combine two different effects.

At the actual 190,000 kWh, the reference offer would cost £58,200 before the separate advisory fee. The difference between that reference and £54,400 is £3,800. Deducting the £1,000 fee gives a £2,800 procurement difference. The remaining £3,000 of the £5,800 total is the effect of 10,000 fewer kWh valued at the reference 30p rate. The arithmetic reconciles; the reason for the consumption change still requires investigation.

Do not confuse a consumption movement with efficiency

The example does not establish that an efficiency measure saved 10,000 kWh. Occupancy may have changed. A laundry service may have moved off site. Weather, extensions, equipment use or measurement differences may also affect the result. The team needs an explanation supported by records, not an attractive percentage applied to the invoice.

CIBSE’s public overview of TM63 describes a framework for evaluating building energy performance in use, including calibrated modelling and distinctions between operational changes and technical shortcomings. That overview informs the principles discussed here; this guide does not implement the full technical method. A complex investment may need a competent specialist to design and validate an appropriate method. ^[2]

For a routine review, retain monthly consumption, occupied bed-days where relevant, significant operational changes and the dates of interventions. Consider appropriate local weather information for weather-sensitive demand. Electricity should not automatically be adjusted using a heating relationship, and heating demand should not be compared using annual occupancy alone. Where the available record cannot support an adjustment, present the unadjusted movement with a clear limitation.

Avoid using registered capacity as though every bed were occupied. Conversely, a cost per occupied bed can rise when occupancy falls even if total expenditure is stable. Present both the numerator and denominator. These indicators help identify questions; they cannot alone establish poor performance or justify reducing essential provision.

Review the whole financial boundary

Reconcile the simplified analysis with the real invoices. Include standing, capacity, metering, network and other applicable charges within the actual arrangement. Identify which were fixed, variable, passed through or excluded from the original estimate. A unit-rate comparison is incomplete if the compared offers treat another substantial charge differently.

Show taxes and levies separately, using the treatment confirmed for the actual supplies and organisation. Do not infer entitlement from the word care in a business name. Finance should distinguish expenditure from recoverable tax, and obtain suitable advice where necessary. Changes in tax treatment or levy eligibility are not evidence of better commodity purchasing.

Keep refunds and credits in a separate column. A £2,000 correction relating to an earlier billing error may improve this year’s cash position, but it is not a recurring £2,000 annual saving. Confirm that the credit reached the account and whether it corrected an expense, an outstanding liability or a previous estimate. Payment timing is useful information, but it is different from reduced energy cost.

Include service and care outcomes

An outcome review should also record whether the arrangement worked operationally. Were accounts established correctly? Were agreed reports delivered? Did managers spend less time investigating avoidable queries? Were issues resolved by the responsible party? These can demonstrate useful professional support even where market conditions make a simple saving claim inappropriate.

Record any effects on resident comfort, hot-water availability, lighting suitability or essential equipment operation arising from related projects. A financial improvement accompanied by an unresolved care problem is not a completed success. Clinical, maintenance and operational colleagues should assess matters within their competence. The procurement review should not overrule their responsibilities.

Ofgem’s business survey is evidence about reported experience across businesses, not an independent verification of a particular provider’s outcome. That distinction matters when using satisfaction alongside financial measures. A positive relationship is valuable, but the expenditure and delivery claims should still be supported by records. ^[3]

Close with a decision that can be checked

Prepare a short outcome statement showing the period, supplies, objective, comparison basis, fees, tax treatment and limitations. Separate verified findings from provisional estimates. Name the person who checked the invoices and the person responsible for outstanding actions. Record the date on which a provisional result will be reviewed.

The final question is practical: should the provider maintain the arrangement, correct an implementation issue, investigate demand or change the next procurement brief? A careful review can identify a successful decision without claiming certainty that the evidence cannot support. It can also identify an improvement early enough to protect the next year’s care budget.

For the next leadership meeting

Questions to resolve.

1. Which comparison could actually have been chosen at the time?
2. What explains the consumption movement, and how strong is that evidence?
