What Rock Power Connections Ltd does

Rock Power Connections Ltd is a UK-based Independent Connections Provider (ICP) that designs and installs high voltage electrical infrastructure, operating across all Distribution Network Operator (DNO) regions from Low Voltage up to 132kV. Founded in 2012/2013 and headquartered in Bromsgrove, Worcestershire, the company was acquired by Mitie Group plc in November 2021 and now operates as part of Mitie Power & Grid. The firm delivers four integrated service lines: High Voltage Connections for new developments and building repurposing, Building Network Operator (BNO) Services for multi-occupancy residential developments with individual metering, EV Charging Infrastructure connecting super hubs and ultra-rapid charging stations, and DNO Services covering primary substations, switchgear, cable installation, protection and control systems, and retrofit/upgrade work up to 132kV. It is one of the few ICPs with in-house commissioning capability up to 132kV and is one of the UK's largest remaining independent ICPs not affiliated with an IDNO, providing it with material independence in recommending optimal asset adoption arrangements for clients.

The company earns revenue through project-based professional services fees on contestable HV connection works, often awarded via competitive tender, alongside long-term framework agreements with DNOs such as NGED on major projects. Direct sales teams engage with enterprise clients including developers, charge point operators, infrastructure projects (HS2, National Grid, National Highways), and BNO clients, with pricing structured around project-specific quotations covering design, materials, installation, and commissioning. Revenue is also indirectly enhanced by arranging IDNO adoption of installed networks, which generates asset value offers that can reduce net client costs. The business holds NERS (Lloyd's Accredited), NICEIC Approved Contractor, ISO 9001/14001/45001, CHAS, and UVDB certifications, and is positioned as a qualified Principal Contractor under CDM Regulations, serving as a fully accredited turnkey provider for both contestable works and dedicated DNO engineering capacity.

The company has demonstrated significant operational momentum, growing headcount from 90 to 130+ employees over a recent 12-month period and accumulating track-record metrics including 500+ new electrical connections energised, 150+ distribution network substations upgraded, 15MW+ of EV charger capacity installed, and 200+ substations completed over an 8-year framework with NGED. Its customer base spans enterprise clients such as Gridserve, Allego, Roadchef, HS2, National Grid, and NGED, alongside mid-market residential and commercial developers. While revenue is not publicly disclosed, the operational footprint and project scale position it as a mid-sized specialist HV infrastructure contractor within the UK market.
