Fixed energy plans

Set the unit price and standing charge for the length of your contract (up to 5 years)

There are lots of benefits of fixing your business energy price, including:

  • Improved cost certainty. You know what your prices are for however long you agree
  • Simple to manage. Less administration compared to flexible price contracts
  • Peace of mind. Giving you confidence in budget projections
  • Energy360. Adding Energy360 to your contract can help you to get control over your business energy usage. Find out more

Flexible purchasing contracts

Buy all or part of your energy at any point before the month you use it.

Some of the benefits of a flexible price contract are:

  • Freedom. Take advantage of favourable movements in the market
  • Less vulnerability. Long term averaging of prices means you could be less susceptible to sudden price changes
  • Relationships. Through longer term partnerships we can help you to better control your energy spend

Gas supply emergency information

Know your legal responsibilities

If you consume more than 732,000 kWh/Yr (25,000 Therm/Yr) you're classed as a large gas user.

It’s the responsibility of every large gas user to be prepared to cope with a gas supply emergency.

A gas supply emergency is when there isn't enough gas pressure to maintain a safe supply to all customers. Business users may be asked to stop using gas and/or isolate local gas supplies.

You must provide us with emergency contact details so you can be contacted in the event of a gas supply emergency.

Please make sure your usual contact at British Gas has your up-to-date emergency contact information (you'll find their contact details on your bill).

See the emergency contact leaflet (pdf, 44 kb) for more information.
