The scale of the firm’s debt has been laid bare in an update from administrator FRP Advisory filed at Companies House.

Corbyn went into administration in May after more than 35 years in business.

The company also owed HMRC £1.6m and its bankers NatWest £2.5m.

Corbyn only employed eight staff but a raft of self-employed workers were also owed wages when the contractor went down.

FRP said Corbyn was facing a cash flow crisis leaving it unable to pay creditors on time.

The update said suppliers and staff were unlikely to receive a penny for their unpaid invoices and wage slips.

Latest accounts for the company for the year to June 30 2023 show a turnover of £32.8m generating a pre-tax profit of £436,000.
