People in Wales could be owed thousands of pounds in council tax rebates because of confusion surrounding a complicated system and 'misinformation.'
The Welsh Government wants to make it easier for those who are classed as being severely mentally impaired, including sufferers of Alzheimer's, Parkinson's disease and stoke victims, to access the council tax discounts they are already entitled to.
Campaigners argue that people who qualify for the support could be missing out on about £400 a year due to the different approaches taken by local authorities and council staff giving out incorrect information.
The Welsh Government has now become the first to standardise information it gives about the discounts and to offer a single application form across Wales.
Campaign website MoneySavingExpert was behind the calls to change the system in Wales, which will also see people being able to backdate their rebate to the date they were diagnosed. They are now calling for similar changes across Britain.
The Welsh Government says they want to make council tax fairer so that the burden is not placed on those least able to pay.
