B&Q and Comet will no longer accept Kingfisher Gift Vouchers after the voucher company temporarily suspended trading following the collapse of Woolworths.
Woolworths itself is currently the only retailer accepting the vouchers, largely issued to employees through workplace incentive programmes.
The vouchers are issued by Flogistics a wholly-owned subsidiary of Woolworths Group Plc.
A spokesman for Comet said: “In light of recent developments regarding Woolworths, Comet is currently not accepting Kingfisher Gift Vouchers as the voucher scheme is run by the Woolworths business.”
A B&Q spokesman said: “While Woolworths plc is in administration B&Q is no longer accepting a specific type of multi retailer gift voucher, which was sold by a company that is ultimately owned by Woolworths Group Plc. The vouchers being suspended are primarily sold to large corporations for incentive programmes and we are advising anyone in possession of such vouchers to return them to the company who issued them.”
