The UK broadband market is dominated by the 'big six' providers according to research by Topic Point.

During the second quarter of 2006 these six, which are BT, Virgin Media, Carphone Warehouse, Tiscali, Orange and Sky, accounted for 94 per cent of the home broadband market.
Virgin Media and Orange were the biggest losers among the big players, but it was the smaller ISPs, including Pipex, which really fared badly, losing a market share of two per cent between them for the same period.

It also noted that the total number of internet access households had reached saturation point, with the numbers growing "only slowly, if at all".
