Going concern

Affirmed

“The financial statements are prepared on a going concern basis. The balance sheet of the company at 31 December 2024 shows cash at bank and in hand of £1,9 million (2023: £35 thousand), net current liabilities of £15.7 million (2023: £3.2 million) and net liabilities of £11.3 million (2023: assets £3.6 million) and continues to have access to a group cash pool to fund day to day operations. The company is considered well placed to meet its current obligations as they fall due. The directors have received confirmation from the ultimate parent company, Iron Mountain Inc. of its continuing support for a period of at least 12 months from the date of approval of these financial statements. The ultimate decision to move funds within entities is made at group level. The company is reliant on the support of Iron Mountain Inc. to continue as a going concern due to the shared banking agreement. The directors have assessed the latest results of the group company and deem they have sufficient funds to support IM UK Services Ltd for at least 12 months after the signing of these financial statements. At 30 June 2025 Iron Mountain Inc. had facilities of $1,645.6 million (2024: $1,585.1 million) available and not drawn down.”

Significant events

• “In 2024, the company increased the base salary of its operational, logistics and transport staff in its subsidiaries by an average of 6.69%.”
• “Further the Board of Directors approved all employees being given the opportunity to take paid volunteer days for causes of their choice within their communities.”
• “In 2024, there were ongoing efforts to improve ESG Targets. Solar design and development has continued at a further five facilities. Ten UK facilities are now fully supported by LED lighting and the expansion of electric vehicles in London helps significantly contribute towards our target of reducing year-over-year direct greenhouse gas emissions by 3%.”
• “In 2022 and 2023, revenues on a certain customer contract was not determined on the correct basis which led on overstatement of revenue and debtors in 2022 and 2023. The error has been corrected by reflecting the correct amounts based billing rate in the customer contract for revenue and debtors. The prior year comparatives and related notes have therefore been restated accordingly.”
