What CWG Group Ltd does
CWG Group Ltd is a privately held UK specialist construction services contractor founded in 2008 and headquartered in Stevenage, Hertfordshire. The company delivers three integrated service lines — Roofing (flat and pitched systems including bituminous felt, green roofs, asphalting, liquid-applied waterproofing, tiling, slating, leadwork and sheet metal), Retrofit (whole-house energy-efficient improvements such as external wall insulation, cladding, rain screening and window/door replacement, plus Retrofit Assessor/Coordinator services via partners), and Refurbishment (concrete repairs, brickwork, carpentry, HVAS/electrical, suspended ceilings, decorations, groundworks and landscaping). It is positioned as an SME contractor specialising in occupied building environments, with documented delivery across schools, hospitals and community facilities operating during construction (e.g., Jack Hunt Academy with 2,000+ daily users, Leytonstone Leisure Centre serving 2,000+ visitors weekly, and Milton Keynes University Hospital).
CWG primarily serves public sector clients across London and the South East, including local authorities, housing associations, NHS trusts, universities, schools and academies, and acts as a specialist subcontractor to main contractors and building consultancies. Revenue is generated through fixed-price construction contracts and procurement framework agreements, with disclosed project values ranging from £192,336 (Anglia Ruskin University roof renewal) to £5.3m (Milton Keynes University Hospital programme) and £2.5m (Leytonstone Leisure Centre), plus multi-year framework deals such as the £2m/annum Welwyn Hatfield Borough Council window and door programme commencing July 2025. Distribution relies on direct enterprise relationships and appointed-supplier status on six procurement frameworks (South East Consortium, Pagabo, London Construction Pro, LHC, Chic, ProcuPublic).
The firm is accredited to ISO 9001, ISO 14001 and ISO 45001, and holds Trustmark, Constructionline, CHAS, BBA, SWIGA, NIA, Acclaim and 5% Club credentials — a compliance stack that is effectively a precondition for tendering in UK public sector construction. Leadership comprises a Managing Director and seven senior managers averaging 20–40 years of construction experience, supplemented by a graduate development programme. The company is privately held with no disclosed external investors, parent entity, or revenue figures.

CWG Group Ltd competitors and assessment
Company assessmentBroad incumbents
- Keepmoat: UK residential regeneration and refurbishment contractor with strong local authority and housing association relationships. Comparable as a competitor for neighbourhood-level refurbishment and energy-efficiency frameworks across the Midlands and North of England.
- Willmott Dixon: Privately held UK contractor focused on public sector construction, residential regeneration, and decarbonisation retrofit. Directly comparable in pursuit of local authority and housing association decarbonisation programmes where CWG competes.
- Wates Group: Privately held UK contractor with strong public sector, education, and housing association order books, including retrofit/regeneration activity. Comparable as a competitor for the same housing stock and local authority frameworks that CWG targets.
- Kier Group plc: UK-listed construction and infrastructure group with major public sector frameworks. CWG actually delivers subcontract roofing and refurbishment works to Kier, making it both a client and a competitive benchmark for public sector construction delivery at scale.
- Mitie Group plc: UK-listed facilities management and construction services group with extensive public sector relationships across healthcare, education, and local authority estates. Comparable because it competes for similar roofing, refurbishment, and energy-efficiency framework contracts, though at much greater scale and with a broader service portfolio.
- ENGIE UK: Major energy services and regeneration group active in UK social housing retrofit, EWI, and decarbonisation programmes. Engie's logo appears on CWG's client list, illustrating direct competition for the same retrofit framework opportunities.
- VINCI Construction UK: UK arm of global construction group VINCI, delivering public sector building, refurbishment, and facilities projects. Overlaps with CWG on local authority, education, and healthcare construction frameworks.
- Balfour Beatty plc: UK-listed infrastructure and construction group with significant public sector exposure including healthcare, education, and local authority estates. Competes with CWG on selected large-scale public construction and refurbishment frameworks.
- Morgan Sindall Group plc: UK-listed construction and regeneration group; its Property Services division specifically serves housing associations and local authorities on planned maintenance, refurbishment, and retrofit — closely overlapping with CWG's core market.
Direct peers
- Fortem Solutions: UK specialist contractor providing responsive repairs, planned maintenance, and refurbishment for housing associations and local authorities. Closely comparable operating model and customer base to CWG, focused on the residential asset management market.
