Point Topic has downgraded its UK broadband adoption forecast for 2016 by around two million homes.
The analyst previously estimated there would be 26 million individual fixed-line connections in Britain by 2016, but it has revised this figure to 23.88 million.
Oliver Johnson, Chief Executive Officer at Point Topic, said there were two primary reasons for the change.
"The remaining pool of offline households are proving difficult to convert, with disposable income struggling to recover," he stated.
Mr Johnson added that delays to the part-public funded Broadband Delivery UK broadband rollout "has to take a share of the blame".
The government has committed around £1.2 billion in funding in a bid to ensure 95 per cent of the UK has access to super-fast broadband by 2017.
Originally, the Con-Lib coalition was aiming to achieve 90 per cent coverage by 2017.
