Average UK broadband speeds rose to 22.8Mb in the six months to November 2014, Ofcom has reported.
The communications regulator says speeds increased by 4.1Mb from 18.7Mb in May last year, helped by the growing uptake of super-fast cable and fibre services.
Ofcom revealed that almost one in every three (32 per cent) UK broadband connections is now super-fast, up from approximately one in four (24 per cent) in November 2013.
Cable broadband saw a 26 per cent increase in average speeds during this period, bringing average broadband speeds up to 54.4Mb over this platform.
This followed a speed upgrade programme undertaken by the UK's main cable broadband provider Virgin Media.
The average speed of fibre services was found to be 41.6Mb, while ADSL connections - which remain the most common type of residential broadband - recorded 7.3Mb.
In urban areas, average download speeds increased by 21 per cent in the six months to November 2014.
However, no statistically significant change in average speeds in suburban and rural areas was seen over this period.
Steve Unger, Acting Ofcom Chief Executive, said the UK has seen "significant investment" in super-fast broadband, and millions of households are now benefiting from faster speeds and more choice.
"But there’s still more to be done to ensure that everyone can share in those benefits," he claimed.
“It’s encouraging to see continued investment in infrastructure from broadband providers, supported by government funding to bring faster broadband to harder to reach areas."
Mr Unger said that by providing information on average download speeds, Ofcom can help people understand the broadband services available to them.
This can help people get the most from their broadband package, he noted.
