Labour MP Bill Esterson is calling on the government to provide transitional relief to prevent “thousands of businesses falling off a cliff edge”.
He described the rates revaluation pressures on small businesses as “very wrong”.
“Hard working small businesses owners who pay their taxes on time are being clobbered by this,” said the shadow minister for business, energy and industrial strategy.
Elfed Roberts, owner of two Spar stores in Wales, is appealing his rates which are set to double from £15,000 to £30,000 in both stores.
“I might be able to cut hours rather than people but £30,000 is two full-time members of staff,” he said.
“My businesses won’t be able to survive if I have to make that kind of sacrifice.”
