No, broadband (ADSL) connections are provided as a contended service which means that your available bandwidth is shared with other users in order to provide you with the service at the current low cost. As a consequence the actual speed will vary through the day depending on the overall volume of business broadband network traffic.

At peak times the speed may be significantly reduced. However even at these times your line speed is still likely to be faster than with the current fixed rate broadband service.
