The UK may delay by years the rollout of a new survey to provide a more reliable picture of who’s working and who’s not, deepening concern about key economic indicators the Bank of England relies on to set interest rates.

The full adoption of a “Transformed Labour Force Survey” might not come until mid-2027, the UK Statistics Authority has acknowledged in documents quietly released in recent months amid increasing frustration over the current monthly jobs data. The agency had previously hoped to implement the new survey and resolve the issue of declining response rates by this past September.
