A commercial energy audit is a detailed assessment of how a building uses energy. It examines energy consumption across building services systems, identifies inefficiencies and highlights opportunities to reduce energy use and improve performance.
The audit provides building owners, landlords, occupiers and asset managers with a clear understanding of how their building operates in practice. The findings can support investment decisions, help prioritise improvement works and identify opportunities to reduce operating costs.
Energy audits are also used to support wider sustainability and compliance objectives. Recommendations can inform EPC improvement strategies, assist with MEES planning, contribute to ESOS compliance and provide evidence for decarbonisation programmes.
Our audits are delivered in accordance with BS EN 16247 and are suitable for offices, industrial buildings, healthcare facilities, education buildings, retail premises and mixed-use developments.
Many organisations commission an energy audit because they need to understand how a building is performing before committing to improvement works. An audit can identify opportunities to reduce energy use, improve building services performance and develop a more informed strategy for future investment.
While an energy audit is different from an EPC assessment, the findings can help support EPC improvement studies by identifying practical measures that may contribute to better building performance. This can be particularly valuable for landlords and asset managers reviewing portfolio performance and assessing potential future MEES risks.
By understanding both how a building operates and where energy is being used, owners can focus investment on measures that deliver meaningful performance improvements rather than relying on assumptions alone.
Where required, KJ Tait can combine energy auditing, commercial EPC assessment, EPC improvement studies and building services engineering advice to help clients understand both current performance and potential future improvement pathways.

A commercial energy audit is a structured review of how a building uses energy. It examines plant, equipment, controls and operating patterns to identify where energy is being wasted and where practical improvements can be made.
Commercial energy audits are commonly commissioned by landlords, occupiers, asset managers, facilities managers and organisations responsible for reducing operating costs, improving building performance or planning future compliance works.
The scope typically includes a review of energy consumption data, site inspection, assessment of building services systems, operational observations and a report containing prioritised recommendations for improvement.
An energy audit identifies where energy is being used inefficiently. Recommendations may include operational changes, controls optimisation, maintenance improvements or capital investments that reduce energy consumption and unnecessary expenditure.
An energy audit can help identify opportunities that may contribute to EPC improvement. Audit findings can be reviewed alongside EPC modelling to understand which measures are likely to have the greatest impact on building performance and compliance objectives.
Energy audits can provide evidence of how a building performs in operation and identify improvement opportunities that may support future Minimum Energy Efficiency Standards compliance strategies and wider asset management plans.
No. ESOS is a specific regulatory compliance scheme. A commercial energy audit can be undertaken independently of ESOS and is often used to support operational, financial and sustainability objectives across individual buildings or portfolios.
Useful information may include utility bills, half-hourly data, sub-metering data, building drawings, maintenance records, BMS information, occupancy information and previous EPC or energy reports where available.
Commercial energy audits can be undertaken for offices, industrial facilities, education buildings, healthcare facilities, retail premises, mixed-use developments and wider property portfolios.
The audit report provides a clear evidence base for decision-making. Clients can use the findings to improve operational performance, plan capital investment, support compliance activities and develop longer-term decarbonisation strategies.
