Compare Electricity Prices For Your Business

By comparing business electricity rates, you'll find you could make substantial savings from renewal quotes offered by your current energy supplier.

The electricity wholesale market mainly drives prices, but that only accounts for 50% of your tariff. All commercial organisations can procure their contract either directly from their current provider, use comparison services or a specialist energy broker.

Contracts for businesses are different from households because of the terms, government levies, VAT and consumption.

Use this guide to see how the commercial gas and electricity market differs from domestic equivalents and find a deal that's right for your circumstances. The links above go straight to each section, or continue reading below.

How To Switch Business Electricity Contracts

The main reason people should consider switching their energy supplier is to save costs. Most commercially-based contracts consist of a daily standing charge plus a unit cost per kWh that get invoiced monthly.

All providers have fixed-term contracts that last from one year up to five years in length. Only larger organisations benefit from flexible rates based on the current wholesale price.

Tariffs depend on your regional location within the UK, your annual consumption, your meter types and length of contract. Businesses also pay various green taxes plus VAT at 20% on the total bill.

To find out how much you could save, you need to get a comparison of the latest costs by supplier. Use either an online comparison service or a business energy broker.

All commercial contracts for smaller businesses have fixed end dates for at least one year at fixed prices per kWh used. The market is extremely competitive for small and medium-sized enterprises (SME), so it's worth shopping around and comparing all available prices.

If you've not switched in the past 12 months, then you should be able to negotiate a lower deal than your renewal notice.

  • Step 1. Make sure you're within the end of your current contract so you can change suppliers.
  • Step 2. Notify your existing supplier you want to move.
  • Step 3. Get new prices using the methods outlined above.
  • Step 4. Your broker or new provider switches your contract for you.

A similar pricing practice applies for business gas supplies where all providers offer competitive pricing. Utilising the services of an energy broker could save you time and money by using their specialised services. They'll find you the lowest prices in the market or direct from the wholesale market for larger corporations.

On the date of your change, don't forget to take meter readings, so your bills remain accurate.
