Utility connections (National Electricity Registration Scheme)

NERS accredited utility connection civil works

Rospower is a NERS accredited civil engineering contractor, in partnership with UK Power Connections Ltd., delivering the full scope of civil works required to support adoptable electricity infrastructure for new connections across the UK. Working alongside Independent Connection Providers (ICPs), Distribution Network Operators (DNOs), and developers, we provide a single-source solution for the civil elements of LV and HV electricity network installations.

Our accreditation under the National Electricity Registration Scheme (NERS) means every element of our work, from excavation through to final reinstatement, meets the technical and quality standards required for network adoption.

Cable trenching, ducting & underground infrastructure

• LV & HV Cable Trenching: Precision excavation for low voltage and high voltage cable routes with GPS setting-out, traffic management, and full interface coordination
• Adoptable Duct Installation & Draw Pits: Supply and placement of adoptable duct systems, draw pits, marker posts, and cable management features in accordance with DNO specifications
• Joint Bays & Link Boxes: Construction of reinforced joint bays, link boxes, and termination chambers to NJUG and DNO standards

Substation & switchgear foundations

• Substation Civil Works: Formwork, reinforcement, and concrete placement for distribution substation bases, GRP housing foundations, and modular switchroom pads
• Transformer Bases & Reinforced Plinths: Design-compliant manufacture and installation of structural plinths, transformer foundations, and anti-vibration mountings
• Compound Works: Security fencing, palisade enclosures, access hardstanding, and drainage for substation compounds

Utility diversions & reinstatement

• Service Crossings & Diversions: Identification, protection, and temporary or permanent diversion of existing gas, water, telecoms, and electricity services
• Backfilling & Compaction: Engineered backfill in accordance with HAUC and specification requirements, including granular surround, warning tape, and marker placement
• Section 50 & NRSWA Reinstatement: Full highway and footway reinstatement to New Roads and Street Works Act (NRSWA) standards, including permit management and inspection coordination

What is NERS accredited civil engineering?

NERS (National Electricity Registration Scheme) accreditation certifies that a contractor’s civil works meet the technical and quality standards required for adoption onto the electricity distribution network. It covers cable trenching, duct installation, joint bay construction, substation foundations, backfilling, compaction, and highway reinstatement.

What civil works are needed for electricity connections?

Electricity connection civil works include precision cable trench excavation for LV and HV routes, adoptable duct installation with draw pits, reinforced joint bay and link box construction to DNO standards, substation and transformer foundations, and engineered backfill to HAUC specifications with full compaction testing.

How is highway reinstatement managed after utility works?

Highway reinstatement follows New Roads and Street Works Act (NRSWA) standards, with engineered backfill, granular surround, warning tape placement, and surface reinstatement matched to existing carriageway or footway construction. Permit management and inspection coordination with the highway authority ensure compliance throughout the works.

Why developers & ICPs choose Rospower

All civil elements are delivered under independently audited management systems covering quality, environmental, and health & safety performance. By combining NERS accredited civil engineering with our broader construction capabilities, we eliminate the coordination risk between separate civils and electrical contractors, giving clients a single point of responsibility, faster programme delivery, and reduced costs across the connection lifecycle.
