Best Ways to Reduce Industrial Energy Consumption
Industrial energy costs remain one of the largest operating expenses for UK manufacturers and industrial businesses. Machinery, production lines, compressed air, heating, cooling, ventilation, air conditioning and lighting can all place heavy demand on electricity and gas.
Reducing industrial energy consumption is not only about using less energy. It is also about understanding how your manufacturing facility uses energy, where demand changes and whether your current business energy contract still reflects how your operation works.
Businesses in the manufacturing industry that combine energy efficiency measures with proactive energy procurement are often better placed to control long-term costs. Lower usage can reduce waste, while the right energy contract can help make sure you are not overpaying for the energy your site still needs.
In this guide, the business energy specialists at Business Utility Hub explain practical energy saving tips for cutting energy consumption, lowering energy bills and helping industrial sites save energy without disrupting production.
Why industrial energy consumption matters
Industrial businesses are particularly exposed to energy costs because energy is often tied directly to output. If production increases, energy demand usually rises too.
Common drivers include:
- High electricity and gas demand
- Continuous production processes
- Energy-intensive machinery
- Heating, cooling and ventilation
- Compressed air systems
- Process heating
- Pressure on margins and competitiveness
For manufacturing sites, small changes in unit rates, standing charges or consumption can have a clear impact on annual costs. This is why understanding your energy profile is the first step towards finding a more suitable business energy contract.
Understand your industrial energy usage before comparing contracts
Before reviewing suppliers or comparing energy contracts, it helps to understand how energy is used across your site.
Key areas to review include:
- Annual electricity and gas consumption.
- Seasonal demand.
- Peak demand periods.
- Shift patterns.
- Production schedules.
- Areas with the highest consumption.
- Recent operational changes.
Energy suppliers use this information when pricing business energy contracts. If your usage data is outdated, your quotes may not reflect how your site operates today.
For example, if you have added new machinery, increased production hours or changed shift patterns, your previous contract assumptions may no longer be accurate. More accurate usage data helps suppliers provide more suitable quotations and helps your business compare energy options properly.
Carry out an industrial energy audit
An industrial energy audit is both an efficiency exercise and a procurement exercise. It helps identify where energy is being used, where waste is occurring and whether your current energy contract still matches your site.
An audit may include:
- Reviewing electricity and gas bills.
- Identifying energy-intensive equipment.
- Understanding baseload consumption.
- Reviewing half-hourly meter data.
- Identifying wasted energy.
- Comparing current usage with the usage assumed when your existing energy contract was agreed.
Many manufacturing businesses expand production, install new machinery or extend operating hours without reviewing their energy contract afterwards. This can mean these business are still on a tariff based on an older usage profile.
A clear audit gives you better information before you compare suppliers. It also helps you understand whether your costs are being driven by consumption, contract terms or both.
Improve energy monitoring to support better procurement
Better monitoring supports operational efficiency and energy purchasing.
Useful tools include:
- Smart meters.
- Half-hourly meters.
- Energy management systems.
- Sub-metering.
- Real-time monitoring.
- Separate tracking for electricity and gas.
- Monitoring consumption per production line.
For larger manufacturing sites, sub-metering can be particularly useful. It allows you to see which areas, processes or equipment are using the most energy. This can help finance, procurement and operations teams make better decisions together.
Better data also helps businesses compare business gas and electricity suppliers on a more accurate basis. If your supplier understands your real demand profile, it is easier to assess which tariff structure fits your site.
Optimise manufacturing equipment and production processes
Machinery and production equipment are often the largest energy users on industrial sites.
Practical steps include:
- Preventative maintenance
- Efficient motors
- Variable speed drives
- Replacing ageing machinery
- Eliminating unnecessary idle running
- Reviewing production schedules
- Investing in energy-efficient equipment where appropriate
Poorly maintained machinery may use more electricity than necessary. Equipment left running between production cycles can also increase costs without adding value.
Lowering electricity demand may change which energy tariff is most suitable for your site. If your annual usage falls, or your peak demand changes, it is worth reviewing this before agreeing your next business energy contract.
Reduce compressed air energy waste
Compressed air is one of manufacturing’s hidden energy costs. It is widely used across industrial sites, but it can be expensive to produce and easy to waste.
Areas to review include:
- Leak detection
- Pressure optimisation
- Compressor maintenance
- Correct equipment sizing
- Monitoring compressed air demand
Leaks can increase electricity consumption without supporting production. Running compressors at higher pressure than required can also add unnecessary cost.
Reducing compressed air waste can lower electricity consumption and improve long-term energy procurement opportunities. It gives your business a clearer view of the energy actually needed to operate efficiently.
Improve heating, cooling and process heat
Heating, cooling and process heat can be major cost drivers for industrial businesses.
Review areas such as:
- Boiler servicing
- Heat recovery
- Process heating
- HVAC maintenance
- Zoned heating
- Cooling systems
- Pipe insulation
- Seasonal operating settings
Some manufacturing sites use gas for space heating, drying, steam generation or production processes. Others rely more heavily on electricity for cooling, ventilation or refrigeration.
Any change in gas consumption should be reviewed before agreeing a new business gas contract. If your site has improved heating controls, changed production processes or reduced heat demand, your procurement strategy should reflect that.
Upgrade lighting and improve building efficiency
Lighting and building condition can also affect industrial energy consumption.
Useful improvements include:
- LED lighting
- Automated lighting systems
- Lighting controls, such as timers, sensors and zoning
- High-bay lighting
- Using natural light where practical
- Roof insulation
- Wall insulation
- Loading bay doors
- Reducing heat loss
Older industrial buildings can lose heat quickly, especially through roofs, doors and loading areas. Improving insulation, making better use of natural light and using lighting controls can reduce unnecessary electricity and heating demand.
Lower annual consumption may also affect whether your current energy contract still reflects site demand. This is why building improvements should be considered alongside energy procurement, not separately.
Manage production demand more efficiently
Operational planning can have a direct impact on energy costs.
Manufacturers should review:
- Shift planning
- Peak demand management
- Avoiding unnecessary equipment operation
- Scheduling maintenance
- Matching production output with energy demand
Some sites may be able to reduce avoidable peaks by adjusting when high-load equipment runs. Others may be able to reduce idle running between shifts or improve shutdown processes.
Understanding your demand profile helps your business choose energy tariffs that better reflect how the site operates. It also gives suppliers clearer information when pricing your next contract.
Why your business energy contract should change as your site changes
Energy contracts should not only be reviewed before expiry. They should also be reviewed when your operations change.
This includes after:
- Installing new machinery.
- Expanding production.
- Adding new production lines.
- Increasing operating hours.
- Moving premises.
- Improving energy efficiency.
- Reducing electricity or gas consumption.
Operational changes can affect:
- Unit rates
- Standing charges
- Contract type
- Metering requirements
- Supplier suitability
- Overall energy costs
A tariff that worked for your site two years ago may not be the right option today. This is particularly true for manufacturers, where machinery, production schedules and output can change quickly.
Avoid paying more than you need to
Many manufacturers overpay because they do not review their energy position at the right time.
Common issues include:
- Out-of-contract rates
- Deemed rates after moving premises
- Missing renewal windows
- Accepting the first renewal offer
- Remaining on an outdated energy tariff
- Not reviewing usage before comparing suppliers
Businesses should review their options before renewal, where possible. However, if your contract has already ended or your site has been placed on deemed rates, you may still be able to reduce costs by arranging a suitable business energy contract.
This is where a structured procurement review can help. It gives your business a clear view of your usage, current tariff and available supplier options.
