Covid-19 support at British Gas Energy

During the pandemic, British Gas have been working hard to keep all of their customers safe. This meant that non-essential jobs were at times put on hold for customer and staff safety, but they’re back up and running now and able to help customers with non-essential jobs in most parts of the UK. Whilst every precaution is being taken, some emergencies need to be sorted immediately, and again British Gas are looking after their customers here. If you’re self-isolating but have an emergency, British Gas can still fix your problem whilst taking all possible precautions when they do. Check out their dedicated Coronavirus information page for more information.

Secure savings with a British Gas electric car tariff

If you’re moving with the times and have your sights set on an electric vehicle, British Gas is here to help.

You can also schedule charging times remotely, so you can set your car to charge during the cheapest night-time hours.

Free cancellations at British Gas

There’s no need to sweat if you’re thinking of switching energy suppliers, as British Gas offers a 14-day cooling off period in which customers can opt out of their current tariff without any exit fees. If you’re a current customer whose quote is up for renewal, then you can also choose to switch to another supplier within the last 49 days of your contract.
