You no longer need to obtain a Migration Authorisation Code to migrate broadband. Simple contact the new provider with your details to arrange the migration. If you wish to migrate to us, please complete the order, and you will not be asked for a MAC. If you wish to migrate away, simply contact the new provider (from tomorrow) and they can arrange the migration. The lead time has increased from 5 working days to 10 - a significant added delay for which you can thank OFCOM.
