Does anyone know of an alternative number for HES (Home Energy Services) formerly EoN. on 0345-872-8593?
Ken Jones.
The number was previously 0845 872 8593.
It was changed to a 03 number,
0345 872 8593 to make it more customer friendly , which means you can call it for the same price as a call to a 01/02 number, and it will also be included in any inclusive minutes.
They also offer a callback service
