Documents filed at Companies House by administrator FRP Advisory reveal the scale of debts at the Surrey based contractor which has built more more than 300 industrial sheds with a combined value of over £1bn since the company was founded in 1994.

Hundreds of subcontractors and suppliers were left holding unpaid invoices when Marbank went down and those bills are now worthless with unsecured creditors likely to receive nothing.

Last full results for the year to July 31 2023 show a turnover of £66.8m generating a pre-tax profit of £438,000 with Marbank employing 24 staff.

FRP said the company’s records show a net profit for the 2024 financial year of £3.8m but Marbank racked-up “significant losses” in the current financial year.

It’s accounts showed that from August 2024 to March 2025 the company had a turnover of £21m generating a net loss of £12.6m in the seven months.

In February an adjudication award of £365,000 in favour of a subcontractor was made against Marbank with another 20 cases looming “which would be costly and difficult to defend.”

A “significant claim” had also been issued against Marbank for alleged building defects on a project.
