Justice minister Lord Bellamy KC made the announcement at the Civil Justice Council national forum in December.
Drafting on the regime, one of the recommendations made by Sir Rupert Jackson in his 2017 civil justice costs review, is still underway and is subject to ministerial approval in 2023.
The extension would apply to most civil cases up to £100,000 in value, an intermediate track would also be introduced, and there would be four complexity bands in both the fast track and intermediate track.
