How does business electricity pricing work?

Electricity pricing

Business electricity prices and plans are calculated and set up differently to domestic ones.

Business electricity unit prices may be cheaper than domestic ones because of the amount of energy used, but most business customers pay a higher rate of VAT.

Business electricity rates are based on your business size and electricity consumption. It may be calculated on a fixed or a variable rate tariff.

If you have a half-hourly meter, we'll give you a tailored price based on when and how you use electricity.

What if I'm tied into a contract with my existing business electricity supplier?

Read your terms and conditions with care as it's possible that you may not be able to switch contracts for a set period of time. Your contract may mean you have to pay a charge if you want to get out of it before the end date. So, check to make sure any savings you'd make aren't cancelled out by any contract penalties.

If you're tied into a deal, make a note of when the lock-in period is about to come to an end and shop around for quotes at that time.
