How does energy pricing work for large businesses?

The difference in pricing all depends on the type of business energy contract that is best suited to your business. There are several types of business energy pricing, including:

Wholesale energy prices

The wholesale price of energy refers to the price at which energy providers will buy energy from generators. This is a price which can fluctuate depending on many factors including the weather as well as supply and demand.

Retail energy prices

The retail energy price is the cost of energy for customers charged by the provider, a price which is usually higher than that at the wholesale cost. The cost is higher to pay for the distribution, customer service and running of the provider that will supply your energy.


How energy is priced is known as the tariff; charging a fixed tariff means the cost per unit of energy is fixed, whereas valuable tariffs will see the price shift up or down.

How much energy do large businesses use?

The amount of energy a large business uses will vary dramatically depending on its size, type and location. According to the UK government, the average large business will use around 65,000 kWh of gas and over 50,000 kWh of electricity.

Your business will be classed as large by energy providers should its usage of energy rates be the same or more as the figures stated above.

What types of large business energy contracts are available?

Fixed-price tariffs: These tariffs offer a fixed price per unit of energy for a fixed period, which can be anything between one and five years. This is ideal if you’re worried about rising energy costs.

Variable-price tariffs

This means that the price per unit of energy varies, which can depend on the wholesale price of energy. It is slightly riskier to opt for a variable price, especially as large businesses can accrue high energy costs, though as the markets fluctuate the price per unit may go down.

Dual-fuel tariffs

These tariffs offer both electricity and gas from the same provider, which is a convenient option if you’re looking to reduce the number of energy contracts in place.

No standing charge tariff

A standing charge is a fixed daily cost which is paid by you to your supplier, the fee is to pay for issues that may occur. Having no standing charges on your bills might make your unit rate higher than other standard tariffs.

Quick tips on saving on energy bills as a small business

1. Understand your business energy usage and waste

Completing an energy audit on your workspace allows you to locate areas within your business that are using too much, or areas where your business is wasting energy.

2. Use energy-efficient lighting

This isn’t a new idea but it is one that’s often overlooked. Make sure your lighting is energy efficient – it’s a simple switch that is super-quick and cheap, and could save you lots of money across a year.

3. Don’t waste energy

Turning off appliances that are not in use, both overnight or over the weekend can save you some extra cash on your energy bills.

4. Replace appliances with energy-efficient ones

An office kitchen sees a lot of use, the kettle might be boiling on and off all day, microwaves and ovens being reheated every 5 minutes – sound familiar? Replace these energy-guzzling appliances with more efficient versions to save money on your bills.

5. Make it a team effort

You can’t do all of this on your own, getting your employees on board will make these changes much easier. Once your staff are taking it upon themselves to turn off their computers and flick the lights off on the way out you’ll begin to make a saving.

What type of business usually has a half-hourly meter installed?

Most of the businesses that use half-hourly meters will have a high energy usage. Businesses that might work around the clock or large warehouses that use lots of equipment, and lighting and have a high amount of staff will most likely require a half-hourly meter. Examples include:

✔ Department Stores
✔ Distribution Centres
✔ Factories
✔ Warehouses

How do I check if I have a half-hourly meter?

It’s easy to check if you have a half-hourly meter installed at your business. You simply need to check your MPAN number (more information on MPAN numbers).

Your MPAN number (Meter Point Administration Number) can be found on your energy bills. To check if your business has a half-hourly meter look at the code which starts with ‘S’ if the next two numbers are 00, you’ll have a half-hourly meter.
