Demon has announced that it is making changes to its business broadband packages in order to protect its network and the quality of service it provides.

Matt Cantwell, Head of Internet Access at Demon, wrote on the company's blog that an increase has recently been seen in the number of "heavy users" of Demon's business broadband products.

"As a result, we can't continue to support completely unlimited use on these services so we need to introduce a fair usage policy with peak hour usage restrictions," he added.

He went on to explain that less than 0.5 per cent of Demon's existing business broadband customers are classed as heavy users.

Under the new policy, those using the Business 2+ / 2+ PRO services will have a limit of 200GB during peak hours (08:00 to 00:00 GMT), which will be measured over a rolling 30-day period.

Those with the Business 2000 / 4000 / 8000 services will be restricted to 100GB over the same timeframe.

Earlier this week, a study from Virgin Media Business revealed that businesses view broadband services as a vital tool in improving their success.
