Commercial Energy Surveys & Industrial Energy Efficiency Audits
Do you really know where your building or industrial site is using its energy? SJB Smart Electricals provides commercial and industrial energy surveys to help businesses understand electricity consumption, identify avoidable energy waste, investigate high-demand equipment and prioritise practical energy-saving opportunities.
Understanding Your Energy Use Is the First Step Towards Reducing It
A business energy bill tells you how much energy you have purchased. It does not necessarily tell you where that energy went, whether it was needed or what could realistically be done to reduce it.
Commercial buildings and industrial sites frequently develop over many years. New equipment is installed, operating hours change, heating and cooling systems are altered and electrical loads are added without anyone taking a fresh look at the overall energy picture.
An SJB Smart Electricals commercial energy survey helps create that picture. By combining available energy data with an on-site technical assessment, we can help businesses understand how their buildings, electrical infrastructure and operational processes are using energy.

Energy Waste Is Often Hidden in Normal Business Operation
A building can appear to be operating normally while consuming significantly more energy than the business actually requires.
Equipment Running When Nobody Is There
Lighting, heating, ventilation, compressors, pumps, machinery and other equipment may continue consuming energy outside normal occupancy or production periods.
Heating & Cooling Working Against Each Other
Poor controls, incorrect set points or building-management settings can result in systems competing rather than operating as an efficient coordinated system.
High-Consumption Equipment
Understanding which plant, machinery or building services create significant demand helps focus attention where it can have the greatest effect.
Unexpected Base Energy Consumption
A high overnight or weekend baseload can reveal equipment or systems consuming electricity continuously without a clear operational requirement.
Inefficient Lighting, HVAC & Motors
Older lighting, motors, pumps, ventilation and HVAC equipment can create opportunities for control improvements or replacement with more efficient technologies.
Operational Energy Waste
Some savings require little capital expenditure and instead come from changing operating schedules, controls, procedures or employee awareness.
Turn Energy Data Into Useful Business Information
Modern businesses can have enormous amounts of data available from electricity meters, half-hourly readings, sub-metering, building-management systems and equipment monitoring.
The challenge is not simply collecting data. It is understanding what the information means and deciding what action should follow.
Where information is available, an energy survey can examine consumption patterns alongside building occupancy, production schedules and equipment operation to help identify anomalies and opportunities.
Information We May Review
- Electricity consumption records
- Gas or other energy consumption where relevant
- Half-hourly meter data
- Energy bills and tariffs
- Operating and production hours
- Building occupancy patterns
- Existing sub-metering
- BMS / BEMS information
- Major electrical loads
- Site and electrical drawings
- Previous energy reports
From Energy Bill to Practical Improvement Plan
Every site is different, but a useful energy survey should create a clear route from understanding current consumption to deciding what should be done next.
Understand
Discuss the building, business operations, working hours, energy concerns and future plans.
Measure
Review available energy data and undertake appropriate site inspection, measurement and monitoring.
Analyse
Look for unusual consumption, unnecessary loads, poor control and opportunities for greater efficiency.
Prioritise
Present practical measures so management can decide which opportunities justify action or further investigation.
What Can a Commercial or Industrial Energy Survey Consider?
Electrical Distribution
Review where energy enters and is distributed through the site and identify where additional monitoring could provide better information.
Lighting
Review lighting type, controls, operating hours, occupancy and opportunities for LED or improved automated control.
Heating & HVAC
Consider operating times, controls, set points and interaction between heating, ventilation and cooling systems.
Motors, Pumps & Drives
Large motors and pumps may represent significant electrical loads and can justify closer assessment of operating patterns, control and efficiency.
Compressed Air
Industrial compressed-air systems can use substantial energy, making operating times, controls and unnecessary demand important areas to investigate.
Production Equipment
Analyse significant manufacturing or process loads in the context of operating hours, production demand and downtime.
Server & IT Loads
Understand continuous IT, data and communications loads and the associated cooling required to support them.
EV Charging
Assess how planned or existing EV charging affects site consumption, demand and future electrical infrastructure.
Renewable Opportunities
A clear consumption profile can help businesses make better decisions about solar PV, storage and other future energy projects.
Plan EV Charging, Heating & New Electrical Loads Around Real Consumption
Energy surveys are not only about reducing what a site uses today. They can also provide valuable information when the business is planning to increase electrical demand.
Commercial EV charging, electric heating, new machinery, building expansion and other electrification projects can significantly change the load placed on an existing electrical supply.
Understanding the existing consumption profile can help establish whether there is available capacity, where peaks occur and whether energy-management strategies could reduce the need for unnecessary infrastructure upgrades.
Not Every Energy Saving Requires Major Capital Investment
One of the most useful outcomes from an energy survey is separating quick operational improvements from projects that require investment and longer-term planning.
Improve What You Already Have
- Correct operating schedules
- Adjust control settings
- Reduce out-of-hours use
- Improve shutdown procedures
- Staff awareness
- Review unnecessary baseload
Small to Medium Investment
- LED lighting upgrades
- Occupancy controls
- Sub-metering
- Improved BMS controls
- Motor controls
- Electrical monitoring
Long-Term Infrastructure
- Major plant replacement
- Solar PV
- Battery storage
- Building-management upgrades
- Heating electrification
- Electrical infrastructure upgrades
Sometimes a Snapshot Is Not Enough
Certain energy problems cannot be identified from a single site visit because loads vary throughout the day, week or production cycle.
Where appropriate, temporary or permanent monitoring can help build a clearer picture of electrical demand and establish when particular loads are operating.
That information may be valuable when investigating unusual energy bills, high baseload, demand peaks or capacity for new electrical equipment.
Monitoring Can Help Investigate
- Unexpected electricity consumption
- Overnight and weekend baseload
- Maximum demand
- Peak consumption periods
- Individual high-load circuits
- Machinery operating patterns
- Electrical capacity for future loads
- Results after energy-saving measures
Energy Efficiency and Electrical Condition Often Overlap
An energy survey is not the same as an EICR or formal electrical condition report, but looking closely at energy use can highlight areas where electrical systems deserve further investigation.
High loads, poor power quality, overheating components, unbalanced equipment usage or unusual operating patterns may justify a more detailed electrical survey or monitoring exercise.
This is where SJB’s combination of energy consultancy, commercial electrical knowledge and electrical training provides a useful joined-up approach.
Commercial Electrical Consultancy
What Can an SJB Energy Survey Report Give Your Business?
The aim is to give decision-makers information they can actually use rather than producing a technical report that simply gets filed away.
Why Understand Your Commercial Energy Consumption?
Reduce Avoidable Energy Spend
Finding equipment and systems consuming energy unnecessarily can create savings without affecting business output.
Spend Capital Where It Matters
Data helps businesses prioritise measures based on actual consumption rather than assumptions or sales claims.
Reduce Carbon Emissions
Using less energy can support wider sustainability and carbon-reduction objectives alongside direct financial savings.
Understand Future Electrical Capacity
Consumption information can support decisions around EV charging, machinery, heating and wider electrification.
Manage Buildings More Effectively
Facilities teams gain better visibility of how building services and operational systems are actually performing.
Measure Whether Changes Worked
A good baseline allows future consumption to be compared so improvements can be verified rather than simply assumed.
Energy Surveys, ESOS & Business Energy Management
Larger organisations may have formal energy assessment and reporting obligations such as the Energy Savings Opportunity Scheme.
Even where a business is not subject to ESOS, the principles behind a structured energy assessment remain valuable: understand consumption, identify significant energy use and evaluate opportunities for improvement.
An SJB commercial energy survey can support wider energy-management planning and help establish useful technical information. Where a formal statutory ESOS audit or other regulated assessment is specifically required, the exact compliance and assessor requirements should be confirmed at the outset.
Not Just a Compliance Exercise
The most useful energy survey should produce more than a document for a compliance file.
Its real value is helping a business understand which energy-saving opportunities are practical, which deserve investment and how those changes can be integrated into normal maintenance and capital planning.
Energy Surveys for Buildings, Industry & Specialist Sites
Energy use varies dramatically by sector, which is why an industrial energy audit should not be treated in exactly the same way as an office building energy survey.
Energy Consultancy With Electrical Engineering Understanding
Energy consumption and electrical infrastructure are closely linked, particularly as commercial and industrial sites become increasingly electrified.
Electrical Expertise
We understand the electrical systems behind the energy data, not simply the numbers appearing on an energy bill.
Commercial & Industrial Experience
Advice considers operational priorities, production, building use and the realities of working sites.
Consultancy Approach
The focus is understanding the problem and identifying appropriate solutions rather than automatically recommending a particular product.
Training Capability
Where behaviour, procedures or workforce knowledge contribute to energy performance, SJB can also develop appropriate training.
Electrical Project Support
If findings lead to EV charging, monitoring, electrical upgrades or further survey work, SJB can help plan the next stage.
Practical Recommendations
Recommendations are intended to help clients take action, prioritise budgets and make better-informed engineering decisions.

Frequently Asked Questions
What is a commercial energy survey?
A commercial energy survey assesses how a building or business uses energy and looks for practical opportunities to reduce unnecessary consumption, improve controls and make better energy-investment decisions.
What is the difference between an energy survey and an EPC?
An EPC provides a standardised assessment of a building’s energy performance. An operational energy survey can go further by examining how the building or industrial site is actually being used, when equipment operates and where real energy consumption occurs.
Can an energy survey help reduce our electricity bill?
The purpose is to identify where energy is being consumed and highlight potential opportunities to reduce avoidable usage. The actual savings available depend on the building, equipment, operating pattern and measures implemented.
Do you provide industrial energy audits?
Yes. SJB can discuss surveys for factories, manufacturing sites, warehouses, workshops and other industrial environments where machinery, motors, compressed air, HVAC and process equipment can create significant electrical demand.
Can you investigate unusually high electricity consumption?
Yes. Depending on the site and available information, energy data and electrical monitoring can help identify baseload, demand peaks, out-of-hours use or circuits that warrant more detailed investigation.
Can an energy survey help us plan EV charging?
Yes. Understanding existing electricity demand can be valuable when planning additional EV charging load and deciding whether load management or electrical infrastructure improvements are required.
Do you use electrical monitoring equipment?
Where appropriate, electrical monitoring can provide useful information about demand and consumption over time, particularly where a single site visit would not reveal changing operating loads.
Is an SJB energy survey an ESOS audit?
Not automatically. An energy survey can support energy-management and ESOS-related planning, but organisations requiring formal ESOS compliance should confirm the specific current scheme and assessor requirements before commissioning the work.
Can you survey multiple commercial sites?
Yes. Multi-site organisations can discuss a structured programme to review energy consumption across several buildings or operational locations and identify sites that warrant closer investigation.
