The leader of Plaid Cymru, Adam Price, has outlined on Wednesday (21 April) his party's plans to reform the current "unfair and outdated" council tax system.
Price pointed out that the values of properties in different parts of the country have changed differently over the previous 18 years since the last revaluation in 2013.
Price cited Blaenau Gwent where it has increased more than twice as much as in Wrecsam.
The Plaid Cymru leader said that around 20% of the households in the bottom fifth of income distribution would see their council tax bill fall by around £200.
“That is why a Plaid Cymru government would take immediate action to reform this deeply unfair system and help the average household make their weekly budget go further."
“As the IFS [Institute of Fiscal Studies] also notes, making council tax proportional to up-to-date values would lead to average bills falling by more than £160 in Merthyr Tydfil, Neath Port Talbot and Blaenau Gwent."
