The legal move aims to maximise the return to creditors who are collectively owed millions of pounds. Barry Stewart and George Lafferty, from Leonard Curtis, have been managing the administration process.

After conducting a “bank statement analysis”, the administrators determined that McGill is owed the significant sum by United Capital Investments, which is controlled by businessman Graeme Carling and his wife Leanne.

The latest progress report filed by the administrators with Companies House stated: “The joint administrators wrote to UC on a number of occasions seeking proposals for repayment of the balance outstanding of £442,602.

“No proposals for repayment were received, nor any evidence from UC that the sums we were pursuing were not due, despite requests. We then instructed TLT Solicitors to formally take steps to recover the balance outstanding.

“TLT then carried out their own reconciliation of the balance outstanding based on our evidence and wrote to UC seeking repayment of the outstanding sums. No response was received in the required timescale.

“TLT have subsequently prepared a summons which has been served on UC.”

A statement from UC’s former financial officer Kevan Sturrock in response to the claim emphasised that UC remains the largest creditor, with losses estimated at around £2.2 million following McGill’s collapse.

Mr Sturrock told The Courier: “I am surprised and disappointed with the lack of progress that appears to have been made by the administrators in the last six months and the continued investigation into already satisfied questions.

“I have personally attended numerous in-person meetings, video calls, and have provided substantial amounts of information whenever asked. It is bitterly disappointing to read comments that we have not been communicating with the administrators.

“Neither I, nor any representatives of UC have received any communications from the administrators over the past six months, so the comment that we haven’t responded is not a reflection of reality.

“I remain resolute that United Capital Investments holds the position as the largest creditor to McGill Facilities Management.”
