Building energy audits

Are you unsure where energy is being used in your building or where to focus efforts to reduce bills? A building energy audit gives you a clear, evidence-based diagnosis and a prioritised plan for action - from quick wins through to capital projects that deliver measurable kWh and £ savings.

The benefits of commissioning an energy audit

Reduce energy costs quickly by identifying low/ no-cost controls and behaviour changes.

Fund capital projects with robust business cases and payback estimates.

Prioritise action so facilities teams know what to fix first and why.

Remove compliance risk by generating evidence and audit trails compatible with British standards.

What’s included in our Building Energy Audit:

Site walk-round and stakeholder interviews with your facilities/operations staff.
Data collection & analysis (meter & invoice review, consumption profiling, baseline metrics).
Plant and controls inspection (boilers, chillers, pumps, fans, setpoints, timeclocks/control sanity checks).
Opportunity identification covering quick wins, low-cost measures and targeted capex options.
Costed action plan with estimated kWh/£ savings, payback timelines and priority ranking.
Board-ready report and presentation summarising findings, risks and recommended next steps.

Our audits find low-cost controls and capital projects with validated kWh and £ savings—so the recommendations quickly pay back.

Designed for Facilities managers, estates teams, sustainability leads and CFOs and anyone who needs a funded, implementable route to cut energy use, lower costs and demonstrate verified progress.

Problems this audit solves

You don’t know where your energy goes. We map consumption to systems and activities so you can target the biggest savings.

You can’t justify capex. We build defensible business cases with cost, savings and payback timelines.

You need to show progress. We deliver monitoring and KPIs so you can prove savings over time.

Your controls and schedules aren’t working. We identify practical controls fixes that stick.

Data quality is poor. We show how to close gaps and provide templates for ongoing data capture.

You’re paying too much on bills and penalties. We analyse invoices, tariffs and demand profiles.
