UK Labour Force Survey shows improved response but cautions remain
The ONS reports LFS response levels have improved since 2023, but a May 2026 operational error reduced linked records, adding uncertainty to longitudinal estimates.
The story in focus
The Office for National Statistics says Labour Force Survey response levels have improved since 2023, with Waves 2 to 5 above pre-pandemic levels in April to June 2026. However, a May 2026 operational error reduced linked records by around 4,000, adding uncertainty to longitudinal estimates while the broad direction of labour market flows remains unchanged.
- LFS responses rose to 81,193 in April to June 2026, up 36,955 from the 2023 low but 2,869 below late 2019.
- A May 2026 operational error led to around 4,000 fewer linked records, reducing precision of longitudinal estimates.
- The ONS advises caution on short-term changes and says LFS remains the sole source for unemployment and inactivity data.
Response recovery and remaining gaps
The Office for National Statistics (ONS) reports that Labour Force Survey (LFS) response levels have improved since 2023, helped by higher incentives and more interviewers. In April to June 2026 there were 81,193 responses including imputation, an increase of 36,955 from the low point in July to September 2023 but 2,869 below October to December 2019.
Wave 1 interviews almost recovered to pre-pandemic levels, while Waves 2 to 5 exceeded them. The ONS says confidence intervals for employment and inactivity rates have returned to pre-pandemic ranges, but those for unemployment remain wider.
Operational error and data coherence
An operational error in May 2026 caused temporary under-resourcing in telephone collection, reducing successfully linked records by around 4,000 for April to June flow estimates. Simulations suggest the reduction is unlikely to materially change the broad pattern or direction of labour market movements but does reduce precision, especially for net flows.
The ONS notes that coherence between LFS and other sources such as Pay As You Earn Real Time Information remains a challenge. It says the LFS is still the only source for unemployment, economic inactivity and self-employment data, and that the Transformed Labour Force Survey remains the long-term replacement.
Did the May 2026 operational error materially change the ONS's longitudinal labour market estimates?
The ONS says simulations suggest the roughly 4,000 fewer linked records are unlikely to materially alter the broad pattern or direction of estimates, though they reduce precision, particularly for net flows.
