Goldman Sachs-owned Adler & Allan buys 180-strong civils outfit
Private equity-backed environmental services group Adler & Allan has made its biggest purchase yet with the acquisition of South West-based civils contractor Glanville Environmental.
The 180-employee Devon contractor, which specialises in drainage, geospatial surveys and civil engineering, has been snapped up by the Goldman Sachs-owned Adler & Allan Group – a national operator focused on delivering utilities and infrastructure.
Glanville turned over around £31m last year, generating a pre-tax profit of nearly £4m.
The deal marks Adler & Allan’s ninth acquisition in just four years.
Since Goldman Sachs’ private equity arm took ownership in 2021, the Harrogate-headquartered group has been on a rapid growth drive, targeting firms across water, waste, remediation and environmental compliance.
Last reported turnover for the group in 2024 reached £217m, generating an operating profit of £15m and employing around 950 staff.
Recent additions to the group include:
- Glanville Environmental (May 2025): Civils contractor delivering drainage, geospatial and remediation services across the South West.
-
MEL Environmental Solutions (Oct 2024): Sustainable remediation specialist focusing on contaminated land.
-
Utility Line (Mar 2024): Independent connection provider and EV infrastructure contractor.
-
QEMS (Feb 2024): Specialist in engineering solutions and quality testing for utilities.
-
Public Sewer Services (Feb 2024): Field services contractor to the water, energy and environmental sectors.
-
Detectronic Holdings (Mar 2023): Developer of flow and level monitoring tech for water companies.
-
Aqua Consultants (Jan 2023): Operational consultancy for the regulated water and utilities sectors.
-
The Environmental Protection Group (EPG) (2022): Experts in contaminated land and groundwater risk.
-
OHES Environmental (2021): Spill response and risk management consultancy.
Adler & Allan chief executive Henrik Pedersen said: “This acquisition strengthens our position as a turnkey partner to the utilities sector with services from strategic environmental consultancy, data, insight, and analytics, and specialist engineering.”
Glanville’s latest accounts show net assets of just over £5m, with £10m in current assets and around £1.75m in the bank as of March 2024.
Adler & Allan, whose wider group revenue is understood to be nearing $750m globally, is using its Goldman Sachs backing to build a market-leading package of environmental services for UK infrastructure operators under pressure to meet tough ESG and pollution targets.
