What Is a Business Energy Meter?
A Business Energy Meter (also called a commercial energy meter) measures and monitors energy consumption for commercial and industrial establishments. It accurately records electricity, gas, or other energy sources used over specific periods.
These meters provide real-time data on energy usage, enabling informed decisions about optimisation and cost control. The primary purposes include:
- Cost Management — Identifying peak usage periods to optimise operations during expensive tariff hours, achieving energy bill savings.
- Energy Efficiency — Locating energy-intensive processes or equipment to implement energy-saving measures.
- Sustainability — Tracking carbon footprints and reducing environmental impact based on consumption data.
- Accurate Billing — Eliminating estimated billing and ensuring fair, precise charges based on actual usage.
What Are the Types of Business Energy Meters?
Single Rate Meter
Most Irish businesses use single-rate meters charging flat rates regardless of time or day. Standard meters display a 21-digit supply number starting with "03" in a box marked 'S' on energy bills. Best suited for businesses operating Monday to Friday, 8am to 10pm.
Two-Rate Meters
Two-rate meters charge different prices based on usage timing — higher during peak times, lower during quieter periods. Identified by supply numbers starting with "04." Examples include Economy 7 meters (cheaper rates during 7-hour windows) and Economy 10 meters (cheaper rates during 10-hour windows). Best for businesses using significant evening or weekend energy such as restaurants, shops, and hairdressers.
Three Rate Meters
Three-rate meters offer varying charges based on time periods: a day rate (most expensive), a combined evening and weekend rate (lower cost), and a night rate (cheapest). Best suited for continuously busy businesses such as pubs, bars, and nightclubs operating late.
Three Phase Meters
Used by businesses with substantial power requirements (around 1,000+ watts continuous). Three-phase systems reduce power loss, improve efficiency, and maintain constant electrical loads. These meters typically don't automatically transmit data; manual readings from display screens are required.
Half-Hourly Meters
Identified by supply numbers starting with "00," these meters record usage every 30 minutes and automatically transmit data to providers, ensuring accurate billing. Best for large facilities such as offices, factories, and warehouses using 70kW to 100kW+ electricity every 30 minutes.
AMR Devices
Automated Meter Reading (AMR) devices measure both gas and electricity, transmitting readings every 30 minutes. Commonly used by larger businesses not requiring mandatory half-hourly meters. Requires engaging an AMR provider and paying for the service.
Smart Meters
By 2024, ESB Networks planned upgrading all standard meters to smart meters, replacing 2.4 million meters nationally. Smart meters automatically transmit readings to suppliers, eliminating manual submission requirements. Gas smart meters record usage every 30 minutes while electricity smart meters record in near real-time.
Multi-Site Meters
Multi-site meters track energy usage across premises, consolidate multiple tariffs under one supplier, simplify utility management, and potentially reduce costs. Best for businesses operating across multiple locations.

How to Arrange for Installing a Business Energy Meter?
Professional installation ensures accurate readings and seamless system integration. Installation typically involves:
- Assessment — Evaluating business energy needs to determine suitable meter types.
- Choosing the Right Provider — Selecting reputable, experienced providers ensuring smooth installations and ongoing support.
- Installation — Trained technicians install meters and establish data communication systems transmitting usage information to providers and businesses.
- Testing and Calibration — Post-installation rigorous testing ensures accurate readings.
- Data Integration — Meters integrate with business energy management systems, providing real-time data and analytics.
Do I Need a New Energy Meter Installation When Relocating Business Premises?
When relocating, existing meters remain in place for use by current or new suppliers. Installation changes only become necessary if current meters don't suit business requirements. For example, businesses using 100kW every 30 minutes legally require half-hourly meters; if unavailable, suppliers can install them upon request.
How Long Does It Take to Install a New Business Energy Meter?
Standard installations require approximately 5 days to 2 weeks. Additional meter installations may require up to 12 weeks due to on-site work complexity. Early planning with business energy experts is recommended for optimal outcomes.
What Does MPAN and MPRN Mean?
Energy suppliers use unique reference numbers for identification:
- MPRN (Meter Point Reference Number) — Located on business gas bills under "Details of Charges." An 11-digit number.
- MPAN (Meter Point Administration Number) — Also called "S Number" or "supply number." A 21-digit number starting with letter 'S,' found on electricity bills.
