Super-fast broadband was available to almost 20 million homes at the end of last year, a new study has indicated.
Analyst firm Point Topic estimates that 19.6 million households had the option of signing up for fibre broadband on December 31st 2012.
This was up from the 16.9 million with access at the end of June 2012.
And with infrastructure upgrade work continuing during the first two quarters of 2013, it is likely that the 20 million coverage milestone has now been achieved.
However, Point Topic pointed out that the majority of households with access to fibre broadband are yet to sign up for super-fast downloads.
At the end of last year, there were 3.3 million super-fast broadband subscriptions in the UK - just one in six households with access to a fibre connection.
The government wants 90 per cent of UK homes and businesses to have access to super-fast broadband by 2015, with all others able to download at speeds of at least 2Mb.
