Do you actually have to?
Work out your total consumption across all energy carriers — electricity and fuel together, not just the ARMS bill — averaged over the previous three years. Over 10 TJ, about 2.78 GWh, and Article 11 of the EU Energy Efficiency Directive applies.
Nobody tells you that you qualify. EWA does not issue a notification. Working out whether the threshold is met sits with the operator, which is why enterprises tend to discover the obligation late, against a fixed deadline.
Newly obliged enterprises are due by 11 October 2026, with 2025 as the reference year. If you already audited under the previous cycle (S.L. 545.33, last round due 2023), yours falls in 2027 and every four years after.
Below the threshold there is no obligation — and most sites that commission an audit anyway do it because the recommendations pay for it, not because anyone made them.
Three sites, three entirely different problems
“Energy audit” suggests a single procedure. In practice the work barely resembles itself across sectors, because the load is somewhere completely different each time.

Care and therapy facilities
Occupancy-driven, with comfort conditions that are not negotiable — therapy pools, treatment rooms and sensory spaces have set-points you cannot simply relax to save energy. The savings live in control strategy and scheduling rather than in turning anything down.

Refrigeration-dominant sites
Cooling plant typically dominates the load, and it runs continuously regardless of trading hours. Control strategy, door management, condenser condition and defrost cycles usually matter more than the nameplate efficiency of the equipment. Multi-site chains add a second question: whether the same store performs differently from its neighbours, and why.

Production and studio environments
Intermittent, high-draw equipment against highly variable schedules. The gap between scheduled operating hours and actual ones is frequently where consumption escapes, and it does not show up at all in an annual bill — only in interval data read against production schedules.
The point of naming these: an audit that arrives with a fixed checklist will find the same findings everywhere and miss what is actually happening on your site. Which is also why the engagement starts with a conversation about boundaries rather than a template.
Why a walk-through will not do it
ISO 50002 defines audit levels, from a preliminary walk-through up to a comprehensive engineering analysis. EWA guidance is explicit that a preliminary-level audit does not satisfy the mandatory obligation. Obliged enterprises need a level matched to the consumption profile and the complexity of the site.
ISO 50002 also requires independence: nobody involved in the audit should be engaged in operating the activity being audited. That rules out an internal sign-off, and it rules out an audit from a supplier with something to sell you at the end of it.
Reading data against equipment
Consumption data on its own tells you how much. It does not tell you why, and the gap between those two is where an audit either earns its fee or does not.
Equipment behaves differently from its datasheet. Operators work around controls that get in their way. Schedules drift from what the building management system thinks they are. None of that appears in an annual consumption figure, and all of it appears in interval data read against the plant it came from.
That is the difference between an audit that produces a list of standard recommendations and one that produces the two or three changes that will actually move your consumption. Findings are costed and ranked by payback, in a report issued in a form suitable for EWA submission where the audit is mandatory.
Starting
A consultation first — what is in scope, what is not, what level of audit the site actually needs. Nothing gets quoted before that conversation, because quoting a site you have not scoped is guesswork.
Bring ARMS bills, electricity and water, with as much history as you have. That is the minimum. Equipment inventories, operating hours, process detail and any sub-metering get identified during the consultation, matched to what your site actually needs rather than requested wholesale up front.
Timeline follows from site size, complexity and how complete the data is — confirmed at consultation, not quoted generically.
Common questions
How do I know if I am obliged?
Three-year average across electricity and fuel combined. Over 10 TJ (2.78 GWh) and it applies. You have to work it out yourself — there is no notification.
What is the deadline?
11 October 2026 for newly obliged enterprises. 2027 if you audited under the previous cycle.
Is a walk-through enough?
Not for the mandatory obligation. EWA guidance says so directly.
How is this different from an EPC?
An EPC is a standardised rating for a domestic dwelling. An energy audit measures what a commercial or industrial site actually does.
