The UK's first rail fare freeze in 30 years will cost £145m in 2026-27, rising to £775m cumulative by 2030-31. Read our new report for more on the revenue and distributional implications: www.policyengine.org/uk/research/...

NEW: How will the £2,000 cap on salary sacrifice pension contributions affect UK workers? We modelled four behavioural scenarios to show how revenue and distributional impacts vary.

The new high value council tax surcharge will raise £400m/year from £2m+ properties. Top 10 constituencies = 35% of revenue. Cities of London & Westminster alone: 10%. Explore our latest Autumn Budget analysis and interactive: www.policyengine.org/uk/research/...

The OBR revised up its inflation and earnings forecasts in the November 2025 Autumn Budget. We compare the projections and explain what changed for PolicyEngine users. policyengine.org/uk/research/...

NEW: We've modelled the Autumn Budget fuel duty freeze Key findings for 2026-27: - £2.8bn revenue cost - 46.7% of people gain - Lowest decile: +0.30% income - Highest decile: +0.11% income - 0.18% reduction in inequality www.policyengine.org/uk/research/...

Here's how these four landed in the Autumn Budget: Repealing two-child limit ✅ Increasing income tax by 2p ❌ Reducing NI by 2p ❌ Freezing income tax thresholds ✅ Adjusting VAT thresholds ❌ Surcharge on high-value properties ✅ Stay tuned for analysis of other provisions.

Chancellor Reeves delivers the Autumn Budget at 12:30 PM. Here's our analysis of 4 policies the government may announce: 🧵👇

Where would a mansion tax hit hardest? We mapped 2024 property sales above £2m by constituency. Three central London seats account for 21% of all high-value sales nationwide. Explore the interactive map and toggle between thresholds: policyengine.org/uk/research/uk-mansion-tax-autumn-budget

NEW: The Times reported Chancellor Reeves considered raising income tax by 2pp while cutting NI by 2pp. We modeled the package. In 2026-27: +£18.6bn from income tax, -£11.7bn from NI cut. Net £6.9bn. By 2029-30, with the threshold freeze extension: £15.4bn. www.policyengine.org/uk/research/...
