Compare large and industrial business energy prices

Large and industrial businesses typically use significantly more energy than small and micro businesses. 

This increased demand is often a result of operating across multiple premises, employing larger teams, or from using heavier, more power-hungry machinery. If this sounds like your business, then energy costs could make up a big portion of your monthly outgoings. 

Managing energy efficiently is crucial for keeping overheads under control and ensuring sustainability. Making sure you're on the cheapest business gas and electric rates is also a quick and easy way to lower the cost of your energy bills.

Large or industrial business energy is a type of commercial energy supply for organisations with high annual gas or electricity consumption - typically over 55,000 kWh of electricity or 200,000 kWh of gas a year. 

Unlike standard SME tariffs, large business contracts are usually negotiated individually, priced against half-hourly consumption data, and can include structures like flexible, interruptible or pass-through pricing rather than a simple fixed unit rate.

Accurate billing for high-usage businesses depends heavily on metering. Under Ofgem's Market-wide Half-Hourly Settlement (MHHS) reform, all suppliers must move to settling electricity usage on a half-hourly basis for customers with smart or advanced meters, with migration due to complete by December 2026. This builds on the existing P272 rule, which already requires businesses in profile classes 05-08 to be settled using actual half-hourly data rather than estimates.

What is a large or industrial business? 

For energy purposes, the classification of a business as "large" or "industrial" depends on its annual usage.  You are likely to be considered a large or industrial operation if your business uses more than: 

• 55,000 kWh of electricity per year 
• 200,000 kWh of gas per year 

If you use energy on this scale, your business energy bills can make up a large part of your operating expenses.  If so, choosing the right large business electricity plan and gas contract is essential for reducing costs.  

While the process may not be as simple as comparing household energy rates, our commercial energy comparison services can help simplify the process. 

What large and industrial business energy contracts are available? 

The right contract for your business depends on factors such as size, location, and energy consumption. Here are the main options available: 

• Fixed-rate contract: Lock in the unit price of energy for a specific period (1-4 years). This is best for businesses seeking stability and protection from market fluctuations. 
• Flexible rate contract: Rates vary based on wholesale energy prices. This is best for businesses willing to adapt to potential market volatility for savings. 
• Interruptible contract: Agree to temporary supply interruptions during peak demand in exchange for lower rates. This is suitable for large industrial businesses with backup energy sources. 
• Pass-through contract: Pay fixed wholesale energy costs while other charges (e.g., distribution) vary.  Suitable for businesses aiming for transparency and partial rate control. 
• Large site peak day demand contract: Limits daily energy consumption to a predefined threshold, with penalties for exceeding usage limits. Often best for businesses committed to reducing energy consumption. 

For more information, check out our guide to business energy tariffs. 

Do you need a half-hourly electricity meter? 

A half-hourly electricity meter automatically sends energy usage data to your supplier every 30 minutes. This system provides more accurate readings and often leads to cost savings. 

The benefits of half-hourly metering include: 

• Accurate bills: Eliminates estimated readings and ensures you only pay for what you use
• Energy insights: Track usage trends to tailor your large business energy plan to peak and off-peak needs
• Regulatory compliance: Businesses consuming over 100kW/hour are legally required to have these meters. 

Even if your usage exceeds 70kW/hour during peak periods and getting a half-hourly meter isn't mandatory, installing one is recommended. It enhances accountability and simplifies the process when you compare large business energy suppliers. 

Understanding P272 regulations 

P272 is a regulation by Ofgem, the energy regulator, that mandates half-hourly settlements for businesses with certain energy meter profiles (05-08). The goal is to create a balanced electricity grid and improve billing accuracy. 

Key points about P272: 

• Affects businesses with older non-half-hourly meters 
• Promotes better energy price estimation for suppliers, which may lower costs for businesses
• Ensures all bills are based on actual meter readings, eliminating inaccuracies. 

Check the S number on your Meter Point Administration Number (MPAN). If it falls within the 05-08 range, your meter should give half-hourly readings. 

Does your large business need a multi-site energy contract? 

If your business operates across multiple properties, consolidating energy contracts can simplify billing and reduce costs. 

The benefits of a multi-site energy contract include: 

• Streamlined management: A single bill covers all locations. 
• Cost efficiency: Suppliers often offer discounts for bundled contracts. 
• Time saving: Reduces administrative complexity. 

Choosing a multi-site deal will help simplify your large business energy management strategy as you'll have one billing and renewal date for meters across all properties.

Other considerations for high-energy consumption businesses 

There are several ways that having a high energy demand can affect the gas and electricity rates your business pays, including: 

• Peak demand charges: Peak demand refers to times when energy usage across the grid is highest. Suppliers pay more to distribute energy during these periods, often passing these costs on to businesses. It can help to shift non-essential operations to off-peak hours to minimise peak demand charges. 
• Maximum daily quantity (MDQ): Large businesses may face restrictions on how much energy they can draw daily from the National Grid. Exceeding this limit incurs penalties. 
• Potential for lower unit rates - If your business uses a lot of gas and electricity, suppliers might offer you lower unit rates than those available for other businesses. When comparing business electricity and gas, always check the daily cost of the standing charge alongside the unit rates on offer.

If your business uses over 732,000 kWh annually, you might qualify for a “large supply point,” which could provide additional allowances. 

Maximum daily quantity (MDQ) is a type of contractual cap on the amount of gas a large business is permitted to draw from the network on any given day. Exceeding your agreed MDQ can trigger penalty charges, so it's worth reviewing your actual daily usage patterns against your contracted MDQ periodically, particularly if your operations or output levels change

What if your business energy supplier goes bust?

If your business energy supplier goes bust, you'll automatically be placed with another supplier. This supplier is chosen by Ofgem, the energy regulator. If this happens, you won't be tied in and can arrange a fixed deal with that supplier or switch to a new supplier. 

What is large business energy management?

Managing gas and electricity costs is crucial for any energy-intensive business. But effecitve energy management is more than just selecting the right plan. It also involves the following: 

• Monitoring usage: Track energy consumption in real time to identify inefficiencies. 
• Implementing sustainability practices: Reduce reliance on fossil fuels and explore renewable energy options. 
• Optimising contracts: Regularly review and renegotiate contracts to adapt to changing needs. 

Managing energy costs effectively is critical for large and industrial business energy consumers. You can keep on top of costs by understanding your usage patterns, using modern metering technology, and choosing the right contract.

When energy demand is on an industrial scale, finding the right contract can be complex, especially if you have multiple meters. When you compare large business energy rates with MoneySuperMarket, we can help to make it much easier and assist with finding a multi-site deal, if you need one.

How to compare large business energy prices

Large and industrial business energy FAQs

Need to know more about large and industrial business energy? Check out the answers to our most freuqrntly asked questions.

What usage level makes a business "large" or "industrial" for energy purposes?

A business is generally classed as large or industrial if it uses more than 55,000 kWh of electricity or 200,000 kWh of gas a year. Businesses using over 732,000 kWh annually may also qualify for "large supply point" status, which can bring additional allowances.

What is the difference between a fixed and a flexible large business energy contract?

A fixed-rate contract locks in your unit price for a set period, typically one to four years, protecting you from market swings. A flexible contract lets your rate move with wholesale prices, which can lead to savings but carries more risk if the market rises.

Do large businesses have to use half-hourly meters?

Businesses in profile classes 05-08, and anyone consuming over 100kW/hour, are required to have half-hourly metering under Ofgem's rules. By December 2026, half-hourly settlement will be extended more widely as part of the Market-wide Half-Hourly Settlement reform.

What happens if my business exceeds its Maximum Daily Quantity (MDQ)?

Exceeding your agreed MDQ for gas usually triggers penalty charges from your supplier, since it means drawing more from the network than your contract allows. Reviewing your actual usage against your contracted MDQ periodically can help you avoid unexpected costs.

Can I get one energy contract across several large business sites?

Yes, a multi-site energy contract consolidates billing and renewal dates across all your properties into a single agreement. This can reduce administrative time and, in some cases, secure better rates through bundled volume.

What is an interruptible energy contract, and who is it suitable for?

An interruptible contract means your business agrees to temporary supply interruptions during periods of peak demand, in exchange for a lower unit rate. It tends to suit large industrial sites that have backup power sources and can tolerate short-notice supply pauses.

How does peak demand affect a large business's energy costs?

Suppliers face higher distribution costs when energy demand across the grid peaks, and they often pass some of this cost on to large users. Shifting non-essential operations, like certain machinery runs, to off-peak hours can help reduce these charges.

What happens to my energy contract if my supplier goes out of business?

If your supplier goes bust, Ofgem automatically appoints a new supplier to keep your business running without interruption. You won't be locked into that new supplier's terms and can switch or negotiate a fresh fixed deal once the transfer is complete.
