What Renelec Group does
Renelec Group Limited is a privately held UK construction services group headquartered in Devizes, Wiltshire, with additional offices in Chalgrove (Oxfordshire) and Swindon. The group operates six wholly owned subsidiaries — Renelec Building Services Ltd (electrical contracting), Renelec Chalgrove Limited (plumbing and heating plus small works), Renelec Hennion Ltd (mechanical/HVAC), Renelec Groundworks Ltd (civil engineering), Renelec Construction Ltd (general construction, established 2017), and Renelec Limited (group administration) — delivering multi-trade building services across The Midlands, the South, and the South West of England.
The group runs a B2B sales-led contracting model, working directly as a subcontractor and service provider to national house builders (Bellway, Taylor Wimpey, Persimmon, Bovis, Crest Nicholson, Linden, Berkeley), regional house builders (J.A. Pye, Oakford Homes, Beechcroft), housing associations (Curo), main contractors (Lovell, Beard Construction) and public sector clients covering schools, sheltered accommodation, military assets and hospitals. Contract scope ranges from small extensions and one-off residential projects to 300–400 unit housing sites. Delivery combines employed operatives, labour-only subcontractors and specialist subcontractors, supported by industry certifications including NICEIC, ECA, JIB, Constructionline, Safe Contractor and Gas Safe.
Renelec monetises through project-based, one-off contracting engagements across its trade divisions. The company's principal differentiator is its apprenticeship culture: over 80% of the workforce at Renelec Chalgrove progressed through internal training schemes, 90% of supervisors are former apprentices, and the division reports 95% employee retention. The group is independently owned (no parent, PE, or VC investment disclosed) and currently employs 51–100 staff; revenue, ARR and funding figures are not publicly disclosed.
