The Office for National Statistics has set out its latest progress report on replacing the Labour Force Survey with the Transformed Labour Force Survey, with a 2027 transition window still the most likely target.
The ONS posted the update on 11 August 2026, the same day it published new user guidance for the TLFS. The figures show the programme has expanded substantially: according to ONS, the TLFS Plus Survey sample grew from 50,000 to 90,000 households in October 2025, and both the short Core Survey and a Supported Completion service were planned to go live during the second half of 2025. Yet the LFS remains the lead source of UK labour market data while the TLFS runs in parallel — and that won’t change until ONS is satisfied the new survey is ready.
The readiness bar is not yet cleared. ONS has met four of the twelve recommendations set by the Office for Statistics Regulation, with eight still in progress. Wave 1 response levels are now close to pre-coronavirus levels, but Waves 2 to 5 remain below them — a gap ONS will need to close before transition. The OSR has said progress is encouraging but that ONS must assure methodological changes fully before making the switch.
The 2027 window is a target, not a guarantee.
For Kent, the stakes are practical. Local authorities, Jobcentre Plus services and economic development teams across the county use ONS labour market figures to plan skills programmes, training provision and employment support. A change in how headline employment, unemployment and inactivity statistics are produced could affect the comparability of those figures over time — something planners will need to account for. Kent residents who take part in ONS surveys may also notice changes, including online completion support and an updated questionnaire design under the new system.
ONS says the transition timing depends entirely on evidence and user confidence in data quality. The transformation programme has been running since 2014, so the 2027 window — if met — would represent more than a decade of work to modernise one of the UK’s most closely watched statistical series.
