The Bristol-based specialist lodged the notice at the High Court, giving the company temporary protection from creditor action.

Founded in 1988 as an electrical contractor, ACES spent nearly four decades building its reputation across the South West before broadening into mechanical services, fire and security, HVAC, renewables and general works to become a full MEP contractor.

The business recently embarked on an ambitious growth strategy beyond its Bristol base.

After securing a string of projects across London and the South East, including high-end residential work in Knightsbridge, ACES opened a permanent London office last year and expanded its leadership team.

At the time firm said the expansion would enable it to compete for larger and more complex projects while strengthening relationships with clients and supply chain partners across the region.

ACES operates across commercial, healthcare, education, defence, infrastructure, residential and public sector markets for both main contractors and end clients and is understood to employ over 50 staff.
