In a study carried out by the Institute of Directors' (IoD) has revealed dissatisfaction with BT, particularly by IoD members in rural areas.

42 percent of members surveyed by the institute were dissatisfied with BT’s Openreach service, with the figure increasing to 46 percent in rural areas.

Members of the IoD viewed internet speeds as being critical to productivity and that rural speeds were preventing business development. 60 percent of members said they were dissatisfied with mobile download speeds in rural areas.

The research comes after the Governments focus on improving broadband speeds around the UK, with BT so far winning 100 percent of all available funding.

Corin Taylor, senior economic adviser to the IoD, said: "There is a lot of work to be done before the service provided in the real world matches up to the rhetoric coming from Westminster and Whitehall.”
