Control, Operation and Maintenance Agreements (COMA)

Our COMA services give commercial clients structured, professional oversight of electrical systems within occupied buildings. From retail centres to high-rises, our engineers operate under formalised site rules and permit-to-work systems, ensuring safety and continuity. We provide 24/7 switching support and routine maintenance, keeping critical systems compliant with EAWR 1989 and safe for public environments.

• Site-specific safety rules and switching procedures

• 24/7 operational cover for fault response and isolation

• Planned preventative maintenance (PPM) scheduling

• Coordination with building management and FM teams

• SAP and Competent Person coverage for multi-tenant sites

High & Low Voltage Network Design

We deliver LV and HV design solutions for commercial environments with complex occupancy and operational needs. Our engineers produce fully documented designs covering switchgear layout, protection studies, capacity planning, and containment routing — all tailored to work alongside architects, M&E teams, and client branding standards.

• Load analysis for high-occupancy premises

• Distribution and riser design for multi-floor buildings

• Power factor correction and resilience planning

• Protection coordination and earthing studies

• BIM-ready schematics and CDM-compliant packs

Installation and Commissioning

Commercial electrical installations require precision, scheduling discipline, and minimal disruption to end users. We install LV panels, rising mains and containment systems with full RAMS, risk assessments, and client coordination. Commissioning is completed to BS 7671 and manufacturer guidelines, with full test documentation provided for sign-off and warranty.

• Switchgear, riser, and distribution board installations

• Night work, phased shutdowns, and floor-by-floor rollout

• Integration with BMS, fire, and emergency systems

• Certified functional and insulation testing

• Final documentation, O&M files, and test records

‍
High and Low Voltage Jointing

We deliver jointing and terminations across commercial estates, car park feeds, and plant rooms. Our qualified jointers carry out works under controlled conditions, with traffic management, confined access, and reinstatement as required. All work complies to DNO and private network standards.

• Cable jointing and termination (LV & HV)

• Sub-main extensions and cable modifications

• CT chamber and panel terminations

• Testing and phasing post-jointing

• Jointing in restricted or public-facing environments

Outage Planning and Support

Electrical outages in commercial spaces demand careful planning, staged execution, and occupant coordination. We provide full outage planning services, including switching schedules, temporary power, safety signage, and stakeholder briefings — reducing risk and minimising impact on operations.

• HV/LV shutdown scheduling and method statements

• Temporary supplies and bypass solutions

• Client liaison and occupant notifications

• Sequenced isolation and energisation procedures

• Post-outage testing and live reinstatement

24/7 Emergency Call-Out

Our rapid-response call-out service supports commercial clients facing loss of supply, nuisance tripping, or urgent electrical faults. Engineers are deployed under SSoW protocols to make safe, investigate, and restore functionality, day or night.

• Emergency switching and isolation

• Power loss investigations and fault repair

• Occupant/public safety management

• Urgent documentation for insurers or regulators

• Follow-up recommendations and remedial planning
