What Are Half-Hourly Metering
Half-hourly metering is a system that records your electricity usage every 30 minutes, instead of just once a day or once a month. This data is automatically sent to your supplier. It shows exactly when and how much electricity your business is using throughout the day.
If your business uses a lot of power, half-hourly metering is either already required or strongly recommended in the UK.
Who Is It For?
Half-hourly metering is designed for UK businesses that:
- Have high electricity consumption.
- Operate long hours or 24/7
- Use heavy equipment, machinery, or HVAC systems.
- Want better control over energy costs.
Many larger sites already have half-hourly meters by law. Smaller and medium-sized businesses are increasingly moving to them to gain better visibility and control.
How It Works
A half-hourly meter automatically records your electricity usage every 30 minutes. This data is sent to your supplier and can be accessed by you or your energy consultant.
Instead of guessing where energy is being used, you can see:
- Morning usage
- Afternoon peaks
- Evening demand
- Overnight baseload
No more estimates. No more surprises.
Why It Matters
With half-hourly data, you can see exactly when your costs are highest. This allows you to:
- Shift usage to cheaper times
- Reduce peak demand
- Switch off unnecessary equipment
- Identify waste quickly
This is one of the most effective tools for cutting energy bills without reducing output.
Is It Complicated?
No. The meter is installed by your supplier or metering provider. Once it’s in, everything is automatic. There is no extra work for your staff.
You simply get better information and better control.
The Bottom Line
Half-hourly metering gives UK businesses visibility, control, and savings.
It shows you exactly how your business uses electricity and where you’re wasting money.
If you are serious about cutting energy costs, half-hourly metering is not optional.
It is essential.
