What a good industrial energy audit covers
| Area | What's checked | |---|---| | Commercial | Contract end dates, deemed rates, fixed vs flexible, tender timing | | Capacity | Agreed kVA against actual peak demand, and power factor | | Levies and schemes | BICS, EII/Supercharger, CCA and CCL rates applied correctly | | Network charges | DUoS bands, TNUoS charging band, line loss factors | | Site | Baseload, compressed air, process heating and cooling, HVAC, lighting | | Monitoring | Where sub-metering would pay back |
How much does a commercial energy audit cost?
A full on-site engineering audit for a manufacturing site typically costs from a few thousand pounds upwards, depending on size and complexity. ESOS audits must be signed off by a Lead Assessor. Before paying for that, it's worth a bill-led review. It's usually free, and it often finds enough zero-capital savings to fund the rest.

Frequently asked questions
It's a review of how a business buys and uses energy, to identify savings. For manufacturers, it should cover the bill (contracts, capacity, levies and charges) as well as on-site efficiency.
Yes. The 5-minute audit and the follow-up weekday consultation cost nothing, and you decide whether anything happens next.
Only an ESOS-compliant audit signed off by a registered Lead Assessor, or ISO 50001 certification, counts for ESOS. A bill-led review is a useful first step but isn't an ESOS audit on its own.
