Almost 16.5 million households in the UK now have internet access, an increase of 1.2 million since 2007, the latest official figures show.
The Office for National Statistics (ONS) said the new figure represented close to two-thirds of UK households.
Homes in the South East are most likely to have internet access with those in north-east England least likely.
Over two-thirds of adults go online every day or almost every day, with men more regular users than women.
In the 35% of households with no access, there was an increase in the proportion that said they did not want the internet at home, from 3% in 2006 to 24% in 2008.
The survey also found that the better educated were more likely to be online.
The ONS said that 93% of adults aged under 70 who had a university degree or equivalent qualification had internet access.
This compared with just 56% of those with no formal qualifications being online.
Communications regulator Ofcom said earlier this month that PC and laptop use had grown fourfold since 2002.
