Checks are to be carried on South Holland households claiming a single person’s discount on their Council Tax bill.
Residents claiming the 25 per cent reduction and whose circumstances have changed are being urged to contact South Holland District Council or they could be fined up to £70.
This is part of an ongoing review to validate legitimate claims and remove those being claimed in error or fraudulently.
The discount, worth at least £240 a year, is given to anyone who claims to be living in a property on their own – currently 11,449 people in the district.
District councillor Gary Taylor, whose portfolio includes revenues and benefits, said: “We will be contacting all those we believe to be claiming incorrectly. I would urge anyone whose circumstances have changed to contact us immediately on 01775 761161.”
