Numbers starting 0800 and 0808 are freephone numbers, used by businesses, helplines, charities and government services.
Ofcom allocates phone numbers to communications providers in blocks. The provider shown is the one Ofcom allocated this block to. It is not the person or business that called you, and the number may since have moved to a different network, because people can usually keep their number when they switch provider. Ofcom does not hold information about individual numbers.
Ofcom says calls to 0800 and 0808 numbers are free from all consumer landlines and mobiles. If you are calling from a business line, check with your provider.
