Our Healthcare Electrical Services
Big Green Electrical provides complete, end-to-end design, installation, and compliance services built to meet the rigorous safety standards of the healthcare sector.

First-class electrical installation
In healthcare environments, continuous electrical power is quite literally a matter of life and safety. Operating theatres, diagnostic equipment, patient monitoring networks, and medical refrigeration units must have access to a reliable, uninterrupted source of power. Even a brief power interruption can disrupt critical medical procedures, corrupt digital patient databases, and put patient safety at risk. Big Green Electrical installs highly reliable, medical-grade uninterruptible power supply (UPS) systems and backup battery banks built specifically for hospitals, local clinics, and residential care homes. We help healthcare estate managers secure critical life-safety circuits, medical storage, and IT infrastructure against sudden power cuts and voltage drops. Upgrading your medical facility with our advanced backup power systems ensures patient safety and maintains full compliance with strict healthcare standards.

Implementing a highly reliable, modular backup power system provides your healthcare facility with a robust shield against power disruptions, protecting patient health and building safety.
In a medical environment, any sudden loss of power to ventilators, monitoring gear, or operating lights is a critical emergency. While backup diesel generators provide long-term power, they can take up to 15 seconds to start and take over the load. Our online double-conversion UPS systems bridge this critical gap, providing an instantaneous transfer to battery power so that life-supporting equipment continues to run without a single microsecond of interruption.
Healthcare facilities store high-value vaccines, insulin, and blood supplies in specialised medical refrigeration units. If your cooling systems lose power during an outage, these sensitive supplies can quickly spoil, resulting in substantial financial losses and wasted medical stock. Our backup batteries ensure your refrigeration networks stay powered, protecting valuable medication and maintaining clinical safety.
Advanced medical diagnostic tools, including MRI scanners, ultrasound systems, and laboratory analysers, are highly sensitive to electrical noise and voltage fluctuations. Unstable grid power can cause calibration errors, disrupt active scans, and damage sensitive internal circuits. Our double-conversion UPS systems constantly clean incoming grid power, providing a smooth, stable voltage output that protects your high-value diagnostic systems.
UK medical facilities must adhere to strict regulatory guidelines regarding emergency power, including Health Technical Memoranda (such as HTM 06-01). Our advanced modular systems are designed and installed to meet these strict safety standards, ensuring your critical life-safety networks have a fully certified, compliant backup power supply.
Big Green Electrical provides complete, end-to-end design, installation, and compliance services built to meet the rigorous safety standards of the healthcare sector.

We begin every project with a detailed assessment of your facility's electrical infrastructure. Our specialist engineers trace critical life-safety circuits, identify sensitive medical gear, and map existing backup networks. We use this data to design a custom backup system that provides the exact run-times and reliability levels needed to protect your patients.
Healthcare environments require the highest possible levels of electrical reliability. We design backup systems using advanced modular racks with built-in N+1 internal redundancy, ensuring that if a single power module experiences a fault, the remaining modules immediately absorb the load. Our designs incorporate separate manual bypass switches, allowing your system to be serviced safely without interrupting power to patient areas.
Our team of qualified, DBS-cleared electricians handles the entire installation process. We install secure containment pathways, modify main medical distribution boards, and integrate the backup systems seamlessly with your existing switchgear. We manage every step in strict compliance with healthcare safety standards to keep your patients, staff, and site fully protected.
To ensure your healthcare facility remains protected around the clock, we provide comprehensive preventative maintenance support. Our engineers conduct regular thermal imaging, test individual battery cells, and clean complex cooling systems. Our modular designs support safe hot-swapping, allowing our engineers to isolate and replace single power modules without powering down your clinical equipment.

Upgrading critical power infrastructure in an active healthcare environment requires a highly accredited, experienced contracting team that can deliver technical excellence without disrupting patient care.
We have extensive experience working inside active care homes, private clinics, and local healthcare centres. We understand the sensitive nature of healthcare environments, and our teams work with the utmost care, professionalism, and respect for patient privacy. We plan every step carefully to prevent delays and ensure patient safety.
Safety and compliance remain our absolute priorities on every project. Every member of our on-site team is fully qualified, DBS-cleared, and highly trained in high-reliability healthcare power systems. We maintain full NICEIC Approved Contractor and SafeContractor accreditations, giving you complete peace of mind that your facility is in safe hands.
We understand that healthcare facilities run 24 hours a day, 7 days a week. We plan all major switchboard upgrades and final system integrations outside of standard clinical hours, coordinating our work to align with your scheduled quiet periods. Our teams can work during nights or weekends to ensure your daily clinical operations continue without disruption.
We provide completely transparent, detailed proposals for all our healthcare clients. Our clear quotes break down the exact costs of equipment, switchboard modifications, and labour, ensuring your management team knows exactly where your budget is being spent. We guarantee our pricing is fixed, with absolutely zero hidden fees or unexpected costs.
