Commercial energy audits

Read the data.Examine the site.Report in writing.

In short

A commercial energy audit is a structured examination of how a building or estate uses energy: a year of meter data, the plant, the operating pattern and the tariff, set against each other. It shows where energy is used that the operation does not need, with the figures behind each finding, and reports the measures worth taking in writing and in order.

What this does not do. It cannot reduce consumption by itself, and it cannot find what the records do not show. Where the data is incomplete, the gap is named in the report rather than estimated around.

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

What an audit examines

Meter and interval data

A year of half-hourly or interval readings, so the pattern of use is seen rather than guessed: baseload, peaks, and what runs when the building is closed.

Operating pattern

Opening hours, occupancy and process schedules, set against the consumption, so use that does not match occupation stands out.

Plant and equipment

Heating, cooling, ventilation, lighting and process plant: what is installed, how it is controlled and when it actually runs.

Tariff and contract

Whether the supply is on the right tariff structure and capacity for the way the site now operates, read against the signed terms.

Out-of-hours use

Overnight and weekend consumption examined first, because it is the use nobody is there to see and the easiest to stop.

On-site generation

Where the site's load and roof or land suggest it, whether generation is worth examining properly, stated as a feasibility question rather than a foregone conclusion.

How it works

  1. Invoice, data and letter of authority

    A recent full invoice per meter, a signed letter of authority, and whatever plant schedule or building information you hold, so we can request the records we do not have.

  2. A year of data assembled

    Twelve months of half-hourly or interval data gathered for each supply. Where records are missing, the gap is recorded as a gap.

  3. Pattern set against operation

    Consumption is read against opening hours, occupancy and process, so use that does not match the operation is identified with the dates and times it occurred.

  4. Site examined where needed

    Where the data leaves a question it cannot answer, the site is visited and what was seen is recorded, with photographs where you permit them.

  5. Report issued in writing

    What was examined, what it showed and the measures worth taking, in order, each with the figures behind it. Where the data does not support a measure, it is left out.

What you receive

A written report: what was examined, what the data showed, and the measures worth taking, in order. Each measure carries the consumption or cost behind it, so you can check the reasoning rather than take it on trust.

Where a measure involves spending money, the report says so plainly and states the basis on which the return is calculated, so the decision is yours with the figures in front of you.

What it cannot do

Worth reading before you start, so the result is not a surprise.

  • An audit reports; it does not change anything by itself. Consumption falls only when a measure is carried out and then confirmed against the meter.
  • It cannot find what the records do not show. Where data is missing, the gap is named rather than filled with an estimate.
  • It is not an ESOS audit and does not carry lead assessor sign-off. Where you are in scope for ESOS, that work has its own rules and its own page.

What it costs

The first review costs nothing. We read your invoices and meter data and tell you whether a full audit is worth doing, before any fee is discussed.

Where a full audit is justified, its scope and fee are set out in writing and agreed before the work begins. There are no charges you have not seen in writing first.

Questions

A structured examination of how a building or estate uses energy: the meter data, the plant, the operating pattern and the tariff, set against each other so that waste is shown with the evidence behind it rather than asserted. The output is a written report with measures stated in order, each with the figures that support it.

An audit is a point-in-time examination: it reads the records, visits the site where the data leaves questions, and reports. Monitoring is continuous measurement after that, so the measures taken are confirmed against the meter rather than assumed to have worked.

Not always. A year of half-hourly data, the invoices and the plant schedule answer much of it. Where the data leaves a question it cannot answer, such as what runs overnight and why, a visit is arranged and what was seen is recorded in the report.

A written report setting out what was examined, what the data showed and the measures worth taking, in order, each with the figures behind it. Where the data does not support a measure, it is left out rather than padded.

The first review, which reads your invoices and meter data and tells you whether a full audit is worth doing, costs nothing. Where a full audit is justified, its scope and fee are set out in writing and agreed before the work begins.

No. ESOS is a statutory scheme with its own qualification rules, coverage requirements and lead assessor sign-off. A commercial audit can feed evidence into ESOS work, but it does not replace it. The ESOS page sets out the statutory position.

Accounts where this 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-07 / Carbon

    100 per cent renewable supply sourced and a solar PV design completed

    Act on Energy

    Work carried out on the charity's own premises under our partnership as their Official Commercial Energy Partner. The solar PV design is a completed design, not installed generation.

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.
