Half-hourly energy monitoring

Every half hour.Read, not filed.

In short

Half-hourly monitoring reads how each supply is used in each half hour of the day, rather than relying on the single total at the bottom of an invoice. It makes the overnight baseload and out-of-hours plant visible, checked for gaps and estimates, and read against how the site actually operates.

What this does not do. Monitoring does not reduce a bill on its own. It shows where the waste sits, and the reduction comes from acting on the finding.

The first review across your invoices costs nothing. Later work is quoted and agreed in writing before it begins. Cost recovery

48 settlement periods

One day, read half hour by half hour.

The shape shows when demand runs. Missing and estimated periods stay marked rather than being smoothed over.

Questions

What clients ask before starting

A record of how much electricity a supply used in each half hour of the day, rather than a single monthly total. It shows when the load runs, not just how much it adds up to.

Half-hourly and AMR meters already do. Smaller supplies are moving the same way under market-wide half-hourly settlement: migration began in October 2025, with around 80 per cent of meters expected migrated by October 2026 and full implementation in May 2027.

Most often an overnight baseload that is higher than the building needs, plant running out of hours, and demand patterns that do not match how the site is used. Where a site is genuinely peaky by nature, we say so.

The invoice gives one total at the end of the month. Monitoring reads the shape of use within it, which is where the waste sits. The two numbers reconcile, but only one of them tells you when to act.

We say so. Estimated readings are labelled as estimates, and where a meter reports nothing we record the gap rather than filling it with a modelled figure.

The first review of your invoices and data costs nothing. Ongoing monitoring is quoted and agreed in writing before it starts, as part of the management arrangement for the account.

How to check this

Each claim on this page is answered by something you can read for yourself. Nothing below states a figure; it names the document or register the claim is held against.

  • Point 01

    We hold a Level 1 Letter of Authority only

    The authority wording sets out what we may do with your data and states that we cannot sign a contract on your behalf. Read it before you sign it.

    Client terms and conditions

  • Point 03

    Every figure we quote carries a dated source document

    Records state the figure, what it is measured against, the document it is taken from and the date on that document. Records still held anonymous are labelled as such.

    Evidence records

  • Point 04

    Consumption figures come from meter and supplier data, not estimates

    Where a reading is estimated or missing, the record says so rather than filling the gap.
