Broadband has taken over UK net use in a few short years
Information gathered by National Statistics (ONS) for September show that 88.4% of Britons are choosing to use broadband rather than dial-up.
The statistics show that 49.2% of those connections are for services advertised at two megabits per second or faster.
But analysis of the figures suggest the broadband market is static, which could mean tough times for service suppliers.
The figure for September is only slightly up on the June total of 86.2%, but indicates a 26% rise over the last 12 months.
The statistics show that broadband has enjoyed a meteoric rise in popularity among net users since services started to be available and affordable.
As recently as April 2003, ONS reports, 81% of people went online via dial-up modems and only 17% had broadband.
The statistics also offer a breakdown of the speeds that people have signed up to, and show that the proportion of people on higher speeds - between two and eight megabits per second (Mbps) - has grown. Only 4% of those questioned were using services faster than eight Mbps.
Analysts Point-Topic say there is evidence for a slowdown on broadband take-up as the pool of dial-up users diminishes.
Broadband net firms have relied on converting people from dial-up for most of their growth over the last 12 months, said Tim Johnson, chief analyst at Point-Topic.
Mr Johnson said this could spell tougher times for net firms.
Not only were dial-up users resisting being converted, but households without net access, estimated to number about 10 million, were also declining to sign up in large enough numbers to sustain growth.
