Mannings Group

What Mannings Group does

Mannings Construction Group is a privately held, family-owned main contractor and design-build partner founded in 1975 by Jimmy Manning and acquired in 2004 by Aidan Delamere. The company delivers construction projects ranging from €1 million to €70 million across Ireland and the United Kingdom, serving enterprise clients in retail, industrial/logistics, healthcare, education, office, residential, mixed-use, and data centre sectors. Notable enterprise clients include Tesco, Aldi, Decathlon, Amazon, GLS, Quintain, and Handford Developments, with high repeat business rates driven by long-standing relationships. The company operates from four regional offices in Dublin (headquarters), Newry, Milton Keynes, and Ipswich, and employs 72 people across the group.

The firm's core technology centers on construction management using Lean Construction principles, Passiv-Haus energy efficiency standards, and BREEAM/LEED certification methodologies. Mannings pioneered the world's first Passiv-Haus certified retail project and Ireland's first non-domestic Passiv-Haus project, and deploys a proprietary 'Invisible Methodology' for construction in live operational environments. The company has achieved BREEAM Outstanding and Very Good ratings on completed projects, Considerate Constructors Scheme perfect scores, and holds ISO 45001 and Safe T Cert (SSIP) accreditations. Notable project delivery includes a €70 million, 77,000m² distribution centre in County Dublin completed within 15 months, which ranked as the ninth-largest building globally by volume at the time.

The business model is project-based main contracting and design-build delivery, with revenue generated through fixed-price construction contracts. Mannings secures work through direct enterprise sales, relationship-based business development, and reputation-driven acquisition, with no intermediary channel partners. Pricing is quote-based and project-specific, varying with scope, scale, and sector. The company is led by Chairman Aidan Delamere, Managing Director Colm Delamere (since 2018), and Chief Financial Director Ronan Quinn, with regional management across Ireland and the UK.
