Commercial Energy Audits
Our centrepiece consultancy service — practical savings, not theory.
Operationally-led commercial energy audits
A commercial energy audit is a structured, on-site review of how a building consumes energy. We benchmark your performance, identify waste and produce a costed plan of measures ranked by payback, disruption and carbon impact.
Our audits are written by consultants who have actually delivered the measures they recommend — so the action plan is realistic, sequenced and ready to procure against.
Who needs this?
Ideal for businesses preparing for ESOS or SECR submissions, owners targeting EPC band uplifts, and any organisation under pressure to reduce operating costs and emissions.

How we help
Audits that deliver real savings, written to satisfy ESOS, SECR and net-zero reporting in one pass.
Common questions
How long does an energy audit take?
Typically 1–2 days on site for a single building, with a full report inside 3 weeks. Larger or multi-site instructions are sequenced over 6–12 weeks.
Will the audit satisfy ESOS Phase 4?
Yes — our audits are structured to meet ESOS Phase 4 and are ISO 50002 aligned, so they can be lodged directly by our in-house Lead Assessor.
Can you cover multi-site portfolios?
Yes — we run portfolio audit programmes with consistent reporting, a single roll-up dashboard and prioritised capex across the estate.
What data do you need from us before the visit?
12 months of half-hourly electricity data, gas/oil bills, asset lists, floor plans and any prior EPC, BRUKL or audit work. We provide a simple data request pack.
What savings should we expect to identify?
Most commercial buildings reveal 15–35% addressable energy savings, with a meaningful portion at sub-3-year payback through controls, lighting and HVAC optimisation.
Do you cover process loads as well as buildings?
Yes — industrial, manufacturing, cold storage and laboratory process loads are routinely included where they are material to total consumption.
Is the audit independent of any supplier?
Entirely. We do not install, supply equipment or take referral fees, so recommendations are impartial and procurement-ready.
Can the audit feed into our net-zero or SECR reporting?
Yes — every audit is aligned with SECR, CSRD and science-based net-zero pathways so the data flows straight into your sustainability reporting.
Do you support implementation after the audit?
Optional — we can run procurement, contractor selection, project management and measurement & verification (M&V) to lock in the savings.
How are recommendations prioritised?
Each measure is ranked by simple payback, IRR, carbon impact, operational disruption and dependency on other works — so leadership can sequence capex confidently.
