Business contact

If you would like to get in touch with Npower's business contact centre, then you can give the number below a call or use the email address provided. As Selectra, at present, only deals with residential energy tariffs, we cannot help you with your business tariff switch. As such, the best way to get information about your Npower business tariff would be to give them a call directly.
