Business Energy Meters: A Complete Guide for UK Business 

The meter at your premises is the foundation of accurate business energy billing. Modern meters can also provide detailed consumption data, helping organisations understand when energy is being used, identify unusual patterns and make better-informed decisions about cost and efficiency.

A business may need a new meter when it opens or moves into a premises, adds a new gas or electricity supply, expands its operations, changes its available capacity, or replaces equipment that is old, disconnected or no longer suitable.

However, there is no single meter that is right for every commercial site. In this guide, we explain the main types of business energy meter, including smart, advanced and half-hourly meters. We also cover how to identify your meter, when an upgrade may be needed and what to expect during installation or replacement.

What is a business energy meter? 

A business energy meter records the gas or electricity used at a commercial premises so the supplier can calculate charges. Each meter is linked to a supply point, network connection and energy account. 

What types of business energy meters are available?

Meters may be described by the way they record data, the tariff they support or the size of the supply. The main options include:

Meter type	How it works	Typical use
Standard or multi-rate	Read manually; multi-rate meters separate use into time bands.	Smaller sites with straightforward requirements.
Smart meter	Sends digital readings automatically through the smart metering network.	Eligible smaller non-domestic sites.
Advanced or AMR	Records interval data and transmits it through an automated data arrangement.	Businesses needing more detailed monitoring.
Half-hourly electricity	Records electricity use in 30-minute periods for settlement and billing.	Higher-demand or more complex supplies.
CT meter	Uses current transformers to measure larger electrical loads.	Sites with high electricity demand.
Gas meter or sub-meter	Measures gas at the main supply, or energy within a particular area or process.	Gas-using sites, landlords and multi-site operations.

What is a smart meter? 

A smart meter is a digital gas or electricity meter that records energy consumption and sends readings automatically to the supplier. This reduces the need for manual meter readings and can help limit estimated billing.

For businesses, smart meters can also provide more detailed information about when and how energy is being used. This data can support more accurate budgeting, highlight unusual consumption patterns and help identify opportunities to reduce waste. However, installing a smart meter does not automatically lower energy costs – businesses need to use the data to inform practical changes.

What are the benefits of smart and advanced meters? 

Smart and advanced meters can reduce reliance on estimated bills and manual readings. They can also provide more useful data for budgeting, procurement and energy management. 

• More accurate billing through regular actual readings.
• Less administration and fewer manual reading errors.
• Earlier identification of unusual use, waste or equipment faults.
• Better comparison between sites, departments or operating periods.
• Stronger evidence for efficiency projects, carbon reporting and invoice queries.
• A meter does not reduce consumption by itself. Savings come from using the data to change behaviour, maintain equipment, correct billing issues or select a more suitable contract.

Are smart meters compulsory for businesses?

No, there is no single rule requiring every UK business to accept a smart meter. Suppliers have obligations to offer suitable smart metering to eligible smaller non-domestic sites, while advanced-meter requirements apply to certain larger electricity and gas supplies.

Market-wide Half-Hourly Settlement is moving electricity settlement towards more granular consumption data. It may support more accurate costs and time-based tariffs, but it does not mean every business needs an immediate meter replacement. Requirements depend on the existing equipment and supplier migration plan.

When might a business need a new meter?

The need for a new meter is usually driven by a change to the premises, supply or operating requirements. Common reasons include:

• Moving into premises where the previous meter has been removed, disconnected or is unsuitable.
• Creating a new connection or increasing capacity for an extension, new equipment or business growth.
• Replacing a faulty, damaged or non-communicating meter.
• Upgrading to automated or half-hourly data to improve billing and energy monitoring.
• Adding sub-metering to allocate consumption between tenants, departments, buildings or processes.

How can you identify a business meter?

Before reporting a fault or requesting an installation, you need to identify the type of meter you currently have and/or the new one you ideally want. 

To do this, collect the meter serial number and supply identifier. The MPAN identifies an electricity supply point, while the MPRN identifies a gas supply point. Both normally appear on bills, while the serial number is also visible on the meter.

How do you arrange a commercial meter installation? 

Getting a new meter installed is simple. Start by speaking to a supplier, broker or metering specialist. Provide the site address, current supplier, MPAN or MPRN, meter serial number, recent bills and a clear explanation of the change required.

The provider will assess the fuel, available capacity, expected electricity load or gas demand, required data frequency and site access. A completely new connection or capacity increase may also require work from the electricity distribution network or gas network before a meter can be installed.

Once the technical and commercial arrangements are ready, an engineer can install or exchange the equipment and record the opening reading. Check the first bill afterwards to make sure the new serial number, reading and tariff have been applied correctly.

How much does installation cost and how long does it take?  

There is no standard commercial installation price or lead time. An eligible smart-meter exchange may be offered without a separate upfront charge, but new connections, capacity upgrades, CT equipment, gas alterations and complex multi-site projects can involve network, survey, labour and ongoing data-service costs.

Lead time depends on equipment, network support, permissions and safe access. Businesses opening or refurbishing premises should begin early and request a written breakdown of costs, responsibilities and dates.

What happens when switching supplier or moving premises?

A smart meter should normally continue sending readings after a supplier switch. AMR and traditional half-hourly supplies may require changes to metering or data appointments, so confirm the process before switching.

When moving, take dated photographs of the closing readings and meter serial numbers. At the new premises, check that the meters are connected, correctly registered and able to support the expected demand. Finally, arrange any new connection or capacity work as early as possible.

What should you do if a meter stops sending readings?

Check whether recent bills use actual or estimated readings, photograph the display and serial number, and submit a safe manual reading where possible. Contact the supplier or metering provider to establish whether the problem relates to the meter, communications or account setup. Keep reference numbers and confirm that later invoices have been corrected.

Frequently asked questions

Do smart meters automatically save a business money?

No. They improve data and billing accuracy, but savings depend on how the business uses that information to reduce waste, manage equipment or change its contract.

Are business smart meters free?

Some eligible exchanges are offered without a separate upfront installation charge. However, network support, capacity changes and specialist commercial metering can carry direct costs, so confirm the full commercial arrangement.

Can a business have smart meters for both gas and electricity?

Yes, subject to site eligibility, supply size, communications and the supplier’s arrangements. Gas and electricity meters remain separate devices even where their data appears in the same portal.

Does a meter exchange change the MPAN or MPRN?

Normally, no. The physical meter serial number changes, but the MPAN or MPRN continues to identify the existing electricity or gas supply point unless the network connection itself is changed.

Do smart meters need Wi-Fi?

No. Smart meters connect through a secure national wireless network.
