Capacity (kVA) review

Analyse.Right-size.Apply.

In short

A capacity review tests the agreed capacity (kVA) recorded for a supply against a full year of half-hourly recorded demand. Set too high, you pay an availability charge every month for headroom the site never uses. Set too low, you pay excess capacity charges instead. The review shows the recorded peak, the headroom above it and whether a change is worth making.

What this does not do. It cannot reduce the electricity you use, and a change to agreed capacity is a request to the network operator, so the level and the timing are theirs to confirm. Where the site plans new plant, charging or expansion, headroom is kept deliberately rather than removed.

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

Twelve-month demand instrument

Measure the space between the peak and the limit.

A full year matters. One quiet month cannot show whether a kitchen, spa or pumping station needs its existing headroom.

Agreed capacityDeliberate headroomMeasured peak

The year, not a snapshot

Highest half-hours identified by date and time.

The recommendation shows the recorded demand, the headroom retained and any planned plant, charging or expansion that changes the answer.

Written recommendation

Keep

The present level remains where the year supports it and future demand needs the headroom.

The review costs nothing. A change request is quoted before submission.

Questions

What clients ask before starting

The headroom reserved for your supply on the local electricity network, measured in kVA. It is charged every month whether or not the site ever draws it, and exceeding it carries charges of its own.

By testing it against a full year of half-hourly recorded demand. The review shows the recorded peak, the headroom above it and when the highest half-hours occurred, so the recommendation rests on a year of evidence rather than a quiet month.

Yes. Both are applications to the network operator, and both are handled the same way: a recommendation in writing first, then the request prepared and submitted if you accept it.

That risk is part of the recommendation. The stated level keeps deliberate headroom above the recorded peak, and where a site plans new plant, charging or expansion, headroom is kept rather than removed.

No. The review and the written recommendation cost nothing. Where you ask us to submit a change, the fee is set out in writing and agreed first, and any charge the network operator applies is shown to you before submission. There is no capital spend on the site.

The timing is the network operator's to confirm, not ours, so we do not promise dates. We prepare and submit the request, chase it, and record the new level once it is confirmed.

Accounts where capacity work has run

  • EV-04 / Consumption

    16 per cent reduction in non-required consumption

    Michels and Taylor

    Taken from metered consumption after energy monitoring was rolled out across the estate, with more than £100,000 of further saving identified separately from agreed capacity (kVA) audits. Guest-facing operations were not altered.

  • EV-05 / Consumption

    Half-hourly waste analysis and full agreed-capacity audit completed

    Broadening Choices for Older People

    Consumption data turned into a costed picture of where energy is used unnecessarily, with reserved capacity right-sized across the estate. An on-site generation feasibility study was completed alongside it.

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.

  • Point 02

    How we are paid is agreed in writing before you sign

    Our margin or management fee is stated in the terms that accompany a recommendation, and nothing is added afterwards.

  • 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.

  • 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.
