  • Do British Gas Offer Smart Meters?

    British Gas customers are entitled to have smart meters installed for free. To qualify, British Gas need to provide either your gas or electricity and your home has to tick a few boxes too. Not all customers can get a smart meter, but you have to log into your account to find out why and what your alternatives are.

    British Gas doesn’t publicly provide any specific criteria regarding who qualifies and who doesn’t. According to the Smart Energy GB campaign, homes with pre-paid meters and pay-as-you-go accounts are eligible.

    For businesses with specific requirements, more complex meter installation solutions are available.

  • What Is British Gas' Cancellation Policy?

    If you’d like to cancel your energy contract with British Gas, simply contact them to let them know you’ll be leaving.  They’ll send you a final meter reading and you’ll be required to pay off the rest of your balance.

    British Gas charges home energy customers £75 per fuel for cancellations.

    Businesses should avoid breaking their business energy contracts as this is likely to cause substantial penalty fees. Companies wanting to switch suppliers at the end of their contract are required to provide at least 30 days’ notice.
