The claim that the Conservatives "presided over the biggest fall in living standards on record" is strongly supported by multiple authoritative sources. **OBR (Office for Budget Responsibility)** — the UK government's official forecaster — confirmed that real household disposable income (RHDI) per person fell by 1.9% in 2022-23, which it described as "the largest fall in any single financial year since ONS records began in 1956-57." The OBR also confirmed that the cumulative two-year fall (2022-23 and 2023-24) was "the biggest two-year drop since records began in 1956-57." The OBR itself used the phrase "biggest fall in living standards" and "record fall" in its own publications. **Resolution Foundation** found that the 2019-2024 parliament was "the worst for income growth since the 1950s" and "the third worst in post-Edwardian Britain." Over the full 14 years of Conservative government (2009-10 to 2023-24), non-pensioner incomes grew by just 7%, compared to 38% in the previous 14 years. **IFS** found that the 2019-2024 parliament was "the worst parliament for growth in material living standards since at least 1961" and that real wages showed no increase between 2010 and 2023. Multiple major media outlets (BBC, Reuters) reported this as "biggest fall in living standards on record," using the OBR's own language. There is some nuance: over the full 14 years, incomes grew slightly rather than falling, and the Resolution Foundation notes that going back before 1950s records, the 1918-1922 parliament saw an estimated 8% fall. However, the OBR's records (from 1956-57) do confirm the biggest single-year and two-year falls on record occurred during the Conservatives' time in office. The claim is a fair characterization of the record.
