What Krol Corlett does
Krol Corlett is a privately held UK construction main contractor founded in the early 1970s by Simon Krol and Dave Corlett, headquartered in Knowsley near Liverpool with regional offices in Manchester and Preston. The company delivers new build, refurbishment, and heritage conservation projects across education, healthcare, heritage, commercial, residential, and industrial sectors, with disclosed individual project values ranging from approximately £600k to £4m and a track record of live-environment delivery for NHS trusts (Alder Hey, Wirral University Teaching Hospital, Northern Care Alliance, Leeds & York NHS Trust), educational institutions (Bolton College, City of Liverpool College, Bacup & Rawtenstall Grammar School), and local authorities (Liverpool City Council, Lancashire Council, South Ribble Borough Council). Technical capabilities include net-zero design demonstrated on Bolton College (solar energy, triple-glazed windows, Wraptight wall construction, up to 250mm insulation), RAAC remediation (Clatterbridge Hospital), and listed-building conservation (Walker Art Gallery, Grade II*).
The company operates through a group structure of three wholly owned businesses: Krol Corlett Construction (core contracting), Krol Corlett Special Projects (specialist division), and Origin Fire Safety (fire safety services), enabling integrated delivery as evidenced on Blackpool Victoria Hospital. Revenue is generated through fixed-price construction contracts won via direct procurement, competitive tendering, and framework agreements (Rise Framework, Schools Maintenance Framework) with both public and private sector clients including Home Bargains, Central England Co-operative, and the Financial Conduct Authority. Headcount is approximately 50+, with certifications including ISO 9001, 14001, 45001, CHAS, Construction Line, and Safe Contractor. Marketing and business development leverage direct sales complemented by event presence at UKREiiF, Housing 2025/2026, IHEEM Healthcare Estates, and Insider North West Property Awards.
The business is currently undergoing a leadership succession from founder-led to professional management: Daniel Tebay rose from apprentice joiner to Managing Director in 2024, with Neil Hoey (Construction Director), Neil Hudson (Commercial Director), Brenda Harrop (Finance Director) promoted concurrently, and Barry Roberts (former 18-year MD of Morgan Sindall's northwest team) joining as Non-Executive Director. Founders Krol and Corlett remain involved in the Group. Project delivery has expanded nationwide in 2025 beyond the historical North West base, covering Leeds, London, Leicester, Wales, Coventry, Cheshire, and Stoke-on-Trent.
