The move comes as the latest newspaper ABC figures out today show that the paper is going from strength to strength with a third consecutive year-on-year increase.
The Times has reported an increase of 14,536 copies a day, up 2.28% year on year, giving the paper a circulation of 652,264 with full-price sales up by over 3%.
The rollout comes as sales of the compact are believed to have hit 300,000, representing 46% of The Times' total sales.
Earlier this week, Marketing reported that The Times was plotting a major autumn marketing campaign as it switches its editorial emphasis to the compact edition. Speculation is that once that figure hits 50%, the primary editorial and marketing focus will switch from the broadsheet to the compact.
In a statement, Times Newspapers said that both the compact and the broadsheet will be available nationwide in the UK.
Robert Thomson, editor of The Times, said: "The Times compact is the UK's best-selling quality compact and the rollout across the country means that more people than ever before will be able to try the new format. Whether in compact or broadsheet form, The Times breaks more stories than any other UK newspaper and offers readers unrivalled comment and analysis from the best journalists in the business."
The Independent went completely tabloid on May 13. So far, this year its circulation is up 14% and in the latest set of ABCs it is up by 0.3%.
The Independent's reasoning for the change was that the number of readers who preferred the broadsheet version was so small that it no longer made business sense to continue to publish it.
"The resources and time that we invest in producing two formats could, we believe, be more usefully invested in continually improving the content of Britain's only quality compact," The Independent said as it changed over.
