MID Certification Explained: What You Need to Know
A practical guide to understanding MID certification and its role in legal electricity metering.
What Is MID Certification?
MID (Measuring Instruments Directive 2014/32/EU) is an EU requirement for electricity meters used in billing and cost allocation. If energy consumption affects payments, the meter must be MID-certified.
When Is MID Certification Required?
MID certification is required when meters are used for:
- Tenant billing
- Sub-metering in residential or commercial buildings
- Energy cost allocation between users
For internal monitoring only, MID is not mandatory — but still recommended.
How to Recognize an MID-Certified Meter
An MID-certified meter is marked with:
- CE marking
- M + year of certification
- Notified Body number
These markings confirm legal compliance within the EU.
Why It Matters
Using MID-certified meters ensures:
- Legal compliance across the EU
- Accurate and trusted billing
- Fewer disputes over energy consumption
