The UK's largest businesses and public sector organisations are failing to take advantage of the benefits provided by broadband and modern technology.
This is according to a new study by O2 and the Centre for Economic and Business Research (Cebr), which claimed this lack of connectivity is costing the UK £30 billion annually.
It said the productivity of UK businesses has fallen since the recession, with the average output per hour worked dropping by five per cent.
In a survey of organisations, 80 per cent claimed staff do not have access to technology that could help them get their work done, like apps and instant messaging.
Ben Dowd, O2 business director, commented: "Too many pay lip service to technology. But the reality is that our businesses and public sector organisations are yet to get the best that technology has to bring."
The study claimed the risk-averse nature of British businesses may be a major factor in the limited uptake of technology, with 25 per cent of those surveyed saying concerns around trust, responsibility and readiness have held back their adoption of new developments.
