GTC has obligations set by Ofgem to investigate all reported cases of unbilled energy.

This might be due to tampering with our equipment, or where customers are not set-up on an energy supply contract with a relevant Energy Supplier.

If suspect energy theft, you can report instances anonymously on the Stay Energy Safe service managed by Crimestoppers. Call 0800 023 2777, or report it online here at Stay Energy Safe.

For more information on energy theft, please view our helpful advice.


If you smell gas or suspect carbon monoxide, call the National Gas Emergency Service immediately on 0800 111 999.


If you think the electricity supply is dangerous, call 0800 032 6990 to report it.
