The Dundee-based firm entered administration for the second time in less than four years in August last year, with the loss of 100 jobs.

A new report from administrators Leonard Curtis shows that the company, latterly registered as McGill Facilities Management Limited, had succumbed with debts of more than £5 million.

The report, published at Companies House, also reveals administrators are investigating financial transactions, including why a coronavirus business interruption loan was transferred to a connected company.

It is also looking into payments made to McGill’s parent company United Capital, which until earlier this year was controlled by Graeme and Leanne Carling.

The report states: “A bank statement analysis indicated that Mcgill (Holdings) Ltd, previously known as United Capital Investments Ltd (name changed in December 2022), owed significant funds to the company.

“The joint administrators have received supporting statements from Mcgill Holdings Ltd refuting the outstanding balance.

“We are currently reviewing the position and a further update will be provided to creditors in our next report.

“Should we believe that sums are due to the company following our review, we will take steps to recover the balance in full.”

Once McGill’s notice of intent to appoint administrators became public, reports surfaced that some employees had not received their wages. Employees then contacted Scottish Construction Now to raise concerns over their pensions - alleging that pension contributions deducted from some employees’ wages have not been paid into the designated pension fund and claiming that the pension scheme has not been registered with HMRC.

Administrator Leonard Curtis is also to examine why 20 McGill employees were never enrolled into the company’s pension scheme despite contributions being taken from their wages.

McGill is also being investigated for passing a contract to a connected company for no payment, and a high number of credit notes being issued – even after administrators had been appointed.

And the report also sets out “numerous issues” with the company’s debtor ledger.

In an interview with The Courier, Mr Carling estimated he lost £2.2m in the demise of the business.
