Have an emergency?

If you have an emergency involving your electricity or gas, the last thing you want is to spend a few minutes listening to hold music.

Potential gas leak - what to do

If you detect or suspect a gas leak on your property, don’t contact Bulb Energy. You should follow these instructions as soon as possible to avoid a potentially deadly situation.

  • Turn off your gas, if possible at the meter.
  • Immediately call the National Gas Service Emergency Line at 0800 111 999. Follow their instructions as they repair the leak.
  • Do not smoke, light any incendiary device or use electrical devices (including your mobile) within your home!

Your gas isn't working

If your gas supply stops unexpectedly during business hours (9am - 6pm Monday to Friday), you can contact Bulb Energy directly using the number below. If it happens outside of business hours, you can contact your energy distributor.

There's no electricity

If you’re sure that it isn’t just a blown fuse you should call 105 to report a power outage. If only some rooms or sections of your home do not have working electricity, it is most likely a problem with your homes electrical wiring. You should call a certified electrician to fix your wiring issues.

Bulb community forums

Bulb Energy also has an array of community forums on its website that is full of FAQs and issues and inquiries raised by other customers. If you have an issue with your gas or electricity service, it's worth looking through the existing forums as someone else may have raised and resolved the exact same issue you're currently facing.

If you don’t find an existing forum that covers your issue, or if it wasn’t resolved to your satisfaction you can start your own forum. Bulb representatives usually respond to inquiries, although it may take a few days. Other customers may also be able to help you in a more timely manner.

Meter readings

Submitting a meter reading is important, as it helps you avoid estimated bills, which are nearly always more expensive than those based on a reading.

Luckily for Bulb customers, submitting a meter reading with the company is a relatively simple affair. There are two methods for submitting a reading. You can log in to your online Bulb Account and click ‘Submit a meter reading’, then choose either gas or electricity. You can also use the Bulb Energy smartphone app and follow the same process.
