There are 570 data exchanges across the UK that have not been included on the list of areas set to benefit from the Broadband Delivery UK (BDUK) project.
Point Topic has released this information as part of its analysis of the government and BT's scheme to bring super-fast broadband to at least 90 per cent of the UK.
In total there are four million homes whose data exchange has not been included in the project so far, which is roughly four per cent of the country's total.
The East Riding of Yorkshire is the area that stands to be most affected, with close to a third (30.7 per cent) of households in the region covered by an exchange that has not been included on the BDUK list.
In Central Bedfordshire, Bedford Borough and Milton Keynes the figure stands at just over one in five homes (21.4 per cent). Meanwhile, in Essex, Southend-on-Sea and Thurrock it is 19.1 per cent.
There are seven other BDUK areas where the number of households not included on the list account for more than ten per cent of the total. These are Suffolk, the Isle of Wight, Berkshire Council, Buckinghamshire and Hertfordshire, Lincolnshire, Northamptonshire and Stafford and Stoke-on-Trent.
Point Topic stressed that while these data exchanges are not included on the BDUK list, that does not mean they will not be incorporated into the project later. However, this does suggest people in these regions may have to wait longer for an improved level of connectivity and should perhaps consider alternatives like satellite broadband.
"It should be emphasised that this is still a fluid situation ... We expect the bulk of these exchanges to make it on to the upgrade path in the not too distant future, although it’s always possible that not every exchange in the UK will be activated as part of the upgrade programme to 2017," the organisation stated.
