Digital UK, a non-profit company set up by the UK government to oversee the transition, began switching off analogue signals region-by-region in 2008.
And now, it will end the transmission of analogue signals in the rest of the country on 24 October, 2012.
The process has been finished across most of the UK and is near to end in the east of England in November when the last of three analogue transmitters to the Anglia region is switched off.
The four remaining regions to switch next year are London, Meridian in the south of England, Tyne Tees in the north east of England, and Northern Ireland.
Afterwards, people who do not switch to the digital form, satellite or cable services, will have to buy digital televisions or set-top boxes to continue viewing.
“The vast majority of people have already switched over to digital because they like the additional choice and there seems to be quite good… and early communications around what’s available for people on lower incomes, or elderly or disabled people,” said Theresa Wise, Independent media analyst.
