Whether it’s for hot water, heating your premises, or fuelling kitchen equipment, gas is an essential fuel for the daily running of your business.

Unlike domestic customers, businesses are able to access gas at a lower per kWh price because they generally use more of it; however, they will usually pay a higher rate of VAT.

The top ten UK sectors that spend the most on energy energy bills:

For businesses looking to save costs, you could fall into a high-energy category if you’re in one of the below sectors:

  1. Private offices
  2. Chemical manufacturing
  3. Hospitality
  4. Food products manufacturing
  5. Hospitals
  6. Non-metallic mineral manufacturing
  7. Basic metals manufacturing
  8. Rubber and plastic manufacturing
  9. Small shops
  10. Paper products manufacturing

So, if you want your next business venture to be as low-energy as possible, try to avoid the above stated industries.

It’s also notable that in the manufacturing and industrial sector, gas is the most commonly used energy source. Gas is less expensive than electricity; however, since gas is a fossil fuel, it is nowhere near as sustainable. This is because it is possible to generate substantial amounts of electricity via renewable means.

The below chart demonstrates the percentage of energy that will come from each source if your business is part of the manufacturing or industrial sector:

On the other hand, businesses in the service sector use energy very differently. See the below infographic for details:

business energy consumption


Is my business a high energy consumer, or a low energy consumer?

A business is regarded as having low energy consumption if its average electricity consumption of is:

less than 33 kWh per day
1,000 kWh per month.

Generally, businesses will be subjected to a 20% rate of VAT on their energy bill, though this can be reduced if they meet the supplier’s requirements for low energy consumption.
You could pay by unit pricing, which is based on the size and consumption of your company, or a fixed business gas price plan, which sees you pay a set price for a fixed period of between one and three years.

Unlike domestic energy costs, business energy prices are driven by the market, meaning they can vary wildly even from day to day. Using an expert comparison service is the best way to ensure you get a good deal on your business energy.

What is it reasonable to expect from a small business energy provider?

If you’re wondering what the normal expectations you can have for your small business energy provider, then you’re not alone here. The energy industry is quite a complex place, and knowing what you can reasonably demand from your supplier can seem a little daunting.

Here are four key things you should expect your small business energy company to offer:

  1. Affordability
  2. Your energy needs to be affordable – otherwise you’ll be running your business in the dark, for fear of racking up a massive bill.

  3. Environmental sustainability
  4. There’s no denying it: cleaner and greener energy sources are the future. Your energy company should be showing at least some signs that they’re living up to their responsibility and doing their bit.

  5. Scalability
  6. Small businesses don’t stay small forever, and it’s important that your energy company can keep up with your rate of growth. Check that your energy company also caters for bigger businesses with higher energy requirements, whilst keeping costs reasonable.

  7. Flexibility
  8. When it comes to business energy, the market is highly variable, and there is scope to make some serious savings if you’re savvy enough. This is why you don’t want to be locked into a contract, and ideally will have an arrangement that doesn’t feature any end-of-contract fees.

The need-to-knows about business energy quotes

Make sure you’re informed about the most important elements included in a business energy contract, so you can understand whether the deal you’re getting is a good one. Here’s what you should be looking out for:

  • Unit rates –
    This is the set amount your business will pay per unit (kWh) of energy that it uses
  • Standing charge –
    This is a fixed daily cost that covers the expense of repairing and maintaining a business’ energy facilities
  • Agreed supply capacity –
    The maximum demand that a business may require from its supplier, ensuring that this amount (and no more) is continuously available
  • Maximum demand (MD) –
    Measured in kWh, this is the highest value of energy a business could use in a half-hour period. This is taken from the highest demand recorded during a calendar month or billing period, which is multiplied by two to give an hourly MD. Penalties can be incurred for exceeding this value
  • Cooling off period –
    A period of time after signing a contract in which you can cancel without afinancial penalty (rarely offered to business customers)
  • The billing period –
    The period of time that a bill will cover, which can be negotiated for more favorable terms with your supplier
  • The renewal window –
    Coming at the end of your contract, this is a 60 or 120-day window, giving you time to find a better deal or stick with your current supplier
  • In order to get the best energy quote for your company, you should:

    • Do your research – you need to understand energy contracts if you want to get the best deal!
    • Read reviews – see how other consumers have rated potential suppliers. There are plenty of credible online sources where you can compare
    • Know your current numbers and consumption pattern – work out when your peak energy consumption times are, and find out your Meter Point Reference Number (MPRN) for gas and your Metering Point Administration Number (MPAN) for electricity
    • Shop around for quotes – don’t just go with the first attractive offer – keep shopping around for a better one, and make sure you get the best deal for your business

    Once you’ve agreed to a business energy contract, you’ll be locked in for the stated time, so make sure it’s definitely the right one for you before committing.
