Simon Allport, Tom Jack and Alan Hudson from Ernst & Young were appointed joint administrators earlier this month and continued to trade the retailing business.
Kingfisher is the parent company of B&Q and ScrewFix.
Allport said: "This deal represents an exceptional outcome for creditors of Focus group DIY. The joint administrators will continue to trade all of the group's stores and will seek further offers for a going concern sale of the group's business and assets."
The retailer avoided administration in 2009 whe BDO insolvency practitioners achieved a Company Voluntary Arrangement to restructure and repay a percentage of debts over a contracted period of time.
The administrators will be left with 147 stores following completion of the deal.
