What Celnor Group does
Celnor Group is a UK-headquartered Testing, Inspection, Certification and Compliance (TICC) platform founded in October 2023 by industry veteran Simon Parrington with private equity backing from Inflexion. Operating from a registered office in Manchester and a primary London office, Celnor has executed over 30 acquisitions in roughly 2.5 years, building a federation of more than 20 (and growing toward 30+) specialist member companies organized into four divisions: Built Environment (geotechnical, geoenvironmental, ecological, materials testing, surveying); Safety & Compliance (environmental testing, asbestos, water hygiene, working-at-height); Risk Management (building surveying, fire engineering, water quality consultancy); and Analytical Sciences (contract research, energy-sector lab testing). Member companies retain their operating brands and customer relationships while sharing group-level support across finance, HR, IT, legal and business development.
The platform's underlying technology centres on UKAS-accredited laboratory networks, specialist field-testing equipment, and accredited electronic risk management tools (notably Hydrop's COMPASS water quality risk management system, which holds UKAS ISO/IEC 17020:2012 accreditation). Services are delivered by chartered scientists, geotechnical engineers, ecologists, arboriculturists and specialist surveyors, with capabilities spanning above-ground, below-ground and underwater surveying through firms such as LandScope Engineering. Member companies collaborate on joint bids and cross-referrals, enabling pursuit of larger multi-disciplinary frameworks than any single member could win independently - exemplified by the £4.5 million three-year Imperial War Museums framework contract awarded jointly to Riverside Environmental, Brownfield Solutions and CHPK Group.
Revenue is generated primarily through project-based professional services delivered to B2B enterprise and public sector clients, with pricing structured as custom quotations per scope of work and supported by multi-year framework agreements. The customer base spans 10,000+ clients across construction and infrastructure, healthcare, education, hospitality, property, energy and industrial sectors, with named logos including the NHS, Imperial War Museums, Great Places Housing Group, universities and local authorities. Headcount has grown from 0 at founding to 2,000+ colleagues across 60+ UK and Ireland locations, plus international operations in the US (via John Turner Consulting) and UAE/Malaysia (via Scaled Solutions). Annualized revenue exceeded £130 million as of March 2025, and Rothschild & Co was engaged in September 2025 to explore ownership options, indicating the platform is approaching a potential sale or recapitalization event.

Celnor Group competitors and assessment
Company assessmentBroad incumbents
- SOCOTEC UK: UK arm of European TICC leader SOCOTEC, providing testing, inspection, and certification services across construction, infrastructure, environment, and energy. A larger established incumbent with overlapping capabilities across most of Celnor's divisions.
- SGS SA: Global leader in testing, inspection, and certification with extensive UK operations across environmental, agricultural, life sciences, and industrial testing. A much larger incumbent that competes with Celnor in several sub-segments, especially Analytical Sciences.
- Bureau Veritas: Global TICC player with significant UK presence across construction, environmental compliance, and asset integrity services. Competes with Celnor across multiple verticals as part of a much broader service portfolio.
- RPS Group: UK-listed environmental and engineering consultancy providing environmental services, geoenvironmental consulting, and built environment advisory. Overlaps with Celnor's Built Environment and Safety & Compliance divisions across construction and infrastructure clients.
- Intertek Group: Global TICC and quality assurance provider with UK operations spanning materials testing, environmental analysis, and product certification. Overlaps with Celnor's Analytical Sciences and Built Environment testing offerings.
- Eurofins Scientific: International testing laboratory group with UK footprint in environmental, food, pharmaceutical, and life sciences testing. Comparable to Celnor's Analytical Sciences division, particularly Drayton Animal Health and Scaled Solutions.
Direct peers
- Marlowe plc: UK-listed TICC consolidator with a similar acquisition-led strategy across testing, inspection, certification and compliance services. Most direct comparable in business model, geography, and customer base, and shares talent lineage with Celnor (Sam McCarthy was previously Marlowe's Head of M&A for TIC).
- Lucion Group: UK-based environmental services and TICC platform that acquired Delta-Simons in 2021 (Simon Clennell-Jones's former firm). Directly competes across environmental, geotechnical, and safety compliance services with comparable customer segments and regulatory drivers.
- Cawood Scientific: UK scientific testing services group led previously by Celnor founder Simon Parrington. Provides analytical, environmental, and agricultural testing through multiple laboratories; closest pre-Celnor comparable for the roll-up testing platform strategy.
Emerging players
- Phenna Group: Private equity-backed UK TICC consolidator pursuing similar acquisition-led strategy across testing, inspection, and compliance niches. Emerging competitor for bolt-on targets and overlap in customer verticals such as construction and built environment.
