A local authority in west Wales could raise council tax bills by a fifth if its proposals are given the go ahead.

Up until earlier this week, Ceredigion County Council had the highest proposed council tax rise in Wales, with plans to bump bills up 13.9 per cent from April.

Neighbouring Pembrokeshire County Council has however this week revealed plans for a 16-21 per cent rise.

Pembrokeshire however currently has the lowest basic Band D Council Tax in Wales, at £1,342.86 a year for 2023-’24, compared to Ceredigion’s £1,553.60 and Carmarthenshire’s £1,490.97.

The latest proposed increases would see the basic part of those bills rise to £1,561.98, £1597.30, and £1,624.69 respectively.

The proposals in Pembrokeshire, which range between 16.31 per cent and 20.98 per cent have been described as “a kick in the teeth for hard working families”.

Members of Pembrokeshire County Council’s Cabinet, meeting on 12 February, are asked to recommend one of three options.

These increases would increase the annual council tax rate by £219.02, £254.34, and £281.73 respectively to the average Band D property.

Pembrokeshire is currently facing a projected funding gap of £31.9m, partly due to a lower-than-expected Provisional Local Government Settlement.

In a report before Cabinet members, the three general council tax options are outlined, with warnings that challenging cuts to council expenditure would still have to be made, even with these huge increases.

Cllr Aled Thomas, Conservative group spokesman for finance reacted to the potential council tax increases, laying the blame at the current ruling administration, led by Councillor David Simpson.

“The recommended council tax increases put forward to cabinet are a stark reality check on how badly this administration has failed to plan for a stable financial future.

“It’s beyond belief that this administration – which has prioritised vanity projects over the needs of Pembrokeshire people – feels that’s it’s acceptable to ask the taxpayer for more money, while heavily cutting services.

“Cllr Simpson’s tenure as leader is becoming increasingly untenable, and the people of Pembrokeshire deserve a new leader as soon as possible that will deliver for their priorities.”

The potential rises also drew the ire of current Conservative Preseli Pembrokeshire MP Stephen Crabb, who is standing in the new seat of Pembrokeshire Mid and South.

“I was disappointed to see reports that Pembrokeshire County Council, currently run by a coalition of unaffiliated councillors, as well as Labour, Plaid and Liberal Democrats members, has proposed council tax rises of between 16 per cent and 21 per cent,” said Mr Crabb.

“At a time when the UK Government in England has capped rises at five per cent, this will be a kick in the teeth for hard working families across Pembrokeshire.

“We all recognise the cost pressures the council are under which is why the Welsh Labour Government should be doing more to support local authorities, not squandering money on increasing the number of politicians in the Senedd.”

Samuel Kurtz MS said: “The potential council tax hike of 21 per cent is a damning indictment of both a flawed local authority funding formula imposed by the Labour Government and councillors who are all too happy spending taxpayers’ money on pet projects rather than the priorities of Pembrokeshire’s people.

“The delivery of statutory services must be the absolute focus of the council and I’m pleased that our Conservative councillors are holding this rainbow coalition to account in County Hall.”

Paul Davies MS added: “These potential council tax rises are totally unacceptable. Hard pressed taxpayers should not have to face such a steep increase in their council tax bills, without a referendum taking place. Any increases beyond five per cent, should be put to local people in a referendum, similar to what has been practiced in England since the 2012/13 financial year.

“It’s also time that the Local Government funding formula is reformed by the Welsh Government to ensure that all Welsh Councils get treated equally. Our council needs strong leadership to fight for the best deal from the Welsh Government, something that it clearly does not have at the moment.”

Cllr Simpson has been contacted for a response.

The final decision on the council tax level will be made by full council when it sets the annual budget on 7 March.

A final decision on council tax rates in Ceredigion is expected to be made on 29 February.
