Virgin Media's up to 152Mb broadband package remains the fastest widely available to UK households, Ofcom has revealed.
The communications regulator - which compared the broadband speeds delivered by the major service providers in November 2014 - found that the super-fast cable package has the greatest capability.
The maximum speeds delivered on Virgin Media's top-tier package were between 159.1Mb and 159.5Mb - more than 7Mb above the maximum advertised.
On average, subscribers to the premium service were able to download at between 129.5Mb and 135.8Mb during November.
At peak times - between 8pm and 10pm on weekdays - average speeds dropped to between 115.0Mb and 124.5Mb.
The nearest rival to Virgin Media's up to 152Mb package was another of the broadband provider's tariffs - its up to 100Mb deal. This achieved average speeds of between 94.3Mb and 99.5Mb, and maximum speeds of between 104.4Mb and 106.5Mb.
At peak times, Virgin Media's up to 100Mb subscribers were able to download at between 86.5Mb and 95.0Mb.
The fastest broadband deal delivered by a rival service provider was BT's up to 76Mb package, which achieved average speeds of between 59.9Mb and 63.1Mb. Ofcom recorded maximum speeds of between 62.0Mb and 65.1Mb, and between 59.3Mb and 62.6Mb at peak times.
Plusnet's up to 76Mb broadband deal was the next-fastest recorded, followed by Virgin Media's up to 50Mb package.
Of the UK's up to 38Mb fibre broadband deals, Sky achieved the fastest average speeds at between 34.3Mb and 36.3Mb during November 2014. Next came BT's up to 38Mb deal, followed by those offered by Plusnet and EE.
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 added.
