The Enquirer broke the news last week that main business Geoffrey Osborne had filed an administration notice after an 18-month restructuring programme and attempts to secure new funding.
Now a further three divisions – Osborne Construction Ltd, Osborne Group Holdings and Osborne Homes Ltd – have followed suit.
Osborne said it is currently in talks with interested parties “with the ambition that aspects of the business will be sold and will continue to trade.”
