Wales council tax bills set to rise by £800 by 2030

Projections released by the UK Treasury show that council tax revenue for Welsh local authorities is expected to increase by 54 % by 2030, adding about £811 to the average Band D property in Wales. By contrast, the same property band in England is forecast to rise by roughly £556. The increase is attributed to the absence of a statutory cap on annual council‑tax hikes in Wales, a policy the devolved Plaid Cymru government has chosen not to adopt.

Separately, Cardiff Council reported that it collected more than £20 million in rental income from its council‑owned homes between April and early July 2026. The revenue, which must be ring‑fenced for reinvestment in housing services, reflects a rise in occupied council properties and seasonal payment patterns.

Both developments highlight the growing fiscal pressures on Welsh households and local authorities as tax and rent revenues climb faster than in other parts of the UK.
