Compressed Air Energy Saving Audits for UK Industry
Understand how your compressed-air system actually operates using measured site data. Our audits assess demand, pressure, power, leakage and system behaviour to identify practical opportunities for reducing waste and improving investment decisions.
Measure First. Then Decide What to Change.
Compressed-air systems often operate very differently from their original design assumptions. Demand can change, leaks can accumulate, pressure may be set higher than necessary and multiple compressors may not be controlled efficiently together.
A measured audit creates a clearer picture of how the system behaves across real production periods, helping separate genuine equipment limitations from leakage, pressure loss, control problems or variable demand.
What an Energy Audit Can Include
Our Audit Process
What We Can Measure
The exact instrumentation depends on the system and audit scope, but measurements can include:
- System pressure
- Flow rate
- Compressor load / unload behaviour
- Current and power consumption
- Operating hours and demand variation
- Voltage and power factor where relevant
- Temperature
- Pressure dew point where included in scope
- Leakage and inappropriate use
- Multiple-compressor sequencing behaviour
Why We Use a Minimum 14-Day Logging Period
A short snapshot can miss weekday/weekend differences, shift patterns, shutdown periods and production peaks. For our standard audit approach, a minimum of 14 days is used to capture a more representative demand profile.
Longer logging may be appropriate where production is highly variable, seasonal or does not follow a normal weekly cycle.
Where Audits Usually Add the Most Value
What You Receive
| Output | What It Helps You Understand |
|---|---|
| Demand Profile | How air consumption changes through operating and non-operating periods. |
| Pressure Profile | Whether pressure is stable and where excessive or insufficient pressure may be occurring. |
| Compressor Utilisation | How installed compressors are loading, unloading and sharing demand. |
| Energy / Cost Estimate | How measured compressor operation translates into electricity consumption and cost. |
| Improvement Actions | Potential leak repair, pressure, control, pipework, air-treatment or compressor changes. |
| ROI Priorities | Where sufficient data exists, estimated savings and payback can help rank investment options. |
Energy Audit Before Buying a New Compressor
Replacing a compressor without first understanding site demand can result in the same system problems continuing with new equipment. An audit can help confirm whether the priority is:
- repairing leaks
- reducing unnecessary system pressure
- improving compressor sequencing or controls
- changing pipework or air treatment
- replacing an inefficient or poorly sized compressor
- adding capacity where genuine demand has increased
ESOS & Energy Management
Measured compressed-air data can provide useful evidence for wider organisational energy-management work and may support information used within ESOS where the system and organisation are in scope.

Compressed Air Energy Audit FAQs
What is an ISO 11011 compressed-air audit?
ISO 11011 provides a recognised framework for assessing compressed-air system energy efficiency. Our audit approach uses measured site data and recognised compressed-air audit principles to assess system performance and improvement opportunities.
Do we need to shut down production?
Data logging can usually be carried out while the compressed-air system remains in normal operation. Installation of measurement equipment is planned around site safety and access requirements.
How long is the data logging period?
Our standard approach uses a minimum of 14 days so that changing production patterns, weekends and non-production periods can be captured more reliably.
Will the audit tell us how much money we can save?
Where the available measurements and site cost data support it, the audit can estimate savings and payback for specific recommendations. These are project estimates rather than guaranteed savings.
Does an audit always recommend a VSD compressor?
No. VSD can be useful where demand varies, but the correct recommendation depends on the measured load profile. In some systems, leak repair, pressure changes, controls, pipework or a different compressor arrangement may be more appropriate.
Does this make us ESOS compliant?
No. A compressed-air audit can support wider ESOS evidence where relevant, but ESOS compliance covers the organisation's qualifying energy use and has separate assessment, reporting and lead-assessor requirements.
