Consumers believe that the difficulty of getting a migration authorisation code (MAC) is a big obstacle to switching broadband provider, according to new research.
The study by Moneysupermarket.com found that 34 per cent of those who have switched in the past year experienced a delay getting a MAC, despite regulations calling on providers to issue the codes within five working days.
One in six suggested the process of getting a MAC was too complicated, while two out of five people said they did not know what the code is.
Mike Wilson, Broadband Manager at Moneysupermarket.com, said he did not understand why delays occur.
He added: "The fact that customers give up on swapping to a better deal solely because of MAC problems is not acceptable - people are losing out on big savings."
Previous research by Moneysupermarket.com revealed that one in three people think super-fast broadband coverage will encourage illegal downloading.
