Our Public Sector Electrical Services
Big Green Electrical delivers complete, end-to-end design, installation, and support services designed to meet the rigorous safety standards of public sector buildings.

First-class electrical installation
Local government offices, community centres, emergency service hubs, and public utility facilities are the backbone of local community support. Even a brief power cut can shut down council databases, disconnect emergency communications, disable building security, and halt local administrative services. For public sector managers, an unexpected power outage can disrupt critical public services, compromise data security, and lead to significant operational backlogs. Big Green Electrical installs professional, high-reliability modular uninterruptible power supply (UPS) systems and high-capacity battery banks designed specifically for public sector buildings. We help estate managers secure critical IT networks, emergency communication systems, and public safety circuits against sudden power cuts and voltage drops. Upgrading your facility's backup power ensures public service continuity and maintains compliance with strict government safety standards.

Implementing a reliable, modular power backup system provides your public sector facility with a robust shield against local grid instability, securing public safety and administrative efficiency.
If your local database servers or administrative networks reset during a power cut, public service delivery is halted and critical records can become corrupted. Our online double-conversion UPS systems deliver an instantaneous transfer to battery power, keeping your administrative databases, telephone networks, and local area networks online with zero interruption.
Emergency dispatch centres, police stations, and public utility offices must maintain active communication networks 24 hours a day. Our advanced modular systems provide absolute power reliability, ensuring emergency communication hubs, security cameras, and automated building access systems remain fully operational during a major blackout.
Public sector budgets are under constant pressure, requiring efficient building operations. Older commercial backup systems can run at low efficiency, wasting valuable public funds as standby heat. We install modern modular UPS arrays that maintain operational efficiencies above 96 percent, reducing standby power loss and lowering your building's monthly utility bills.
Upgrading to high-efficiency, modern backup systems is an excellent way to support your local authority's carbon-reduction goals. Because modern backup batteries require significantly less power from the grid to maintain their standby charge, they reduce your facility's carbon footprint and show environmental responsibility to the local community.
Big Green Electrical delivers complete, end-to-end design, installation, and support services designed to meet the rigorous safety standards of public sector buildings.

We begin every project with a detailed assessment of your public building's electrical setup. Our specialist engineers trace critical safety circuits, map server cabinets, and identify key communication lines, presenting a detailed report on the exact battery run-times needed to protect your public facility.
Public sector demands must grow and adapt within fixed budgets. We design custom backup systems using modular racks that allow you to scale your power backup capacity over time as your public services expand, saving you from paying for excess capacity on day one.
Our team of qualified, DBS-cleared electricians handles the entire physical integration process. We construct custom backup distribution boards, install essential manual bypass switchgear, and connect the UPS arrays directly to your building's primary distribution board, maintaining full compliance with BS 7671 electrical safety rules.
We provide comprehensive preventative maintenance support, including regular thermal imaging, active battery cell testing, and control calibrations. Our modular UPS designs allow our engineers to safely replace single power modules without needing to shut down your public services.

Upgrading critical power infrastructure in an active public sector environment requires a highly accredited, experienced contracting team that can deliver technical excellence without disrupting public services.
We have extensive experience working inside active council offices, community centres, and emergency service yards. We understand that your administrative environments must remain secure, and we plan our work to respect your daily operations and public schedules.
Safety and compliance remain our absolute priorities on every project. Every member of our on-site team is fully qualified, DBS-cleared, and regularly trained in the latest commercial electrical regulations, and we maintain full NICEIC Approved Contractor and SafeContractor accreditations.
We understand that critical public services must remain available. We plan all major switchboard upgrades and final system cut-overs outside of standard office hours, completing key connections during evenings or weekends to ensure your public facility experiences absolutely zero downtime.
We provide completely transparent, detailed proposals for all our public sector clients. Our clear quotes break down the exact costs of equipment, switchboard modifications, and labour, ensuring your financial department knows exactly where your budget is being spent.
