Green Air designs and installs high-reliability generator systems for offices, hospitals, data centres, and public buildings – with rapid response coverage across Essex, Hertfordshire, Cambridge, and beyond.
Our engineers hold NICEIC, CHAS, and REFCOM accreditations, and bring over 40 years of combined experience. We specialise in mission-critical environments – offering tailored solutions with automatic switchover, compliance-ready installs, and scalable support for multi-site businesses across the UK.
We assess your site’s power needs, layout, and available space to recommend a safe and suitable generator setup.
Our engineers specify the right kVA rating, fuel type, switchgear, and any UPS integration – ensuring your backup system is reliable and regulation-ready.
We install the generator, cabling, exhaust system, fuel tank, and automatic transfer switch (ATS) – all to UK safety and electrical standards.
We simulate a real outage, perform load testing, and walk you through system operation – so you know it works before it’s needed.
Our service plans cover routine checks, fuel, batteries, oil, coolant and filters – keeping your system ready 24/7.
With over 40 years of combined experience, Green Air helps organisations stay operational when the grid goes down. From new builds to high-risk sites, we design and install backup systems that keep your business moving.
We integrate standby power into commercial builds and fit-outs - including ATS, fuel access, ventilation, and load planning. Designs are regulation-ready and delivered with smooth handover in mind.
Whether you're powering shared plant rooms or individual units, we design compliant, tenant-ready backup systems that meet safety codes and support insurance needs.
We support uptime for logistics hubs, care homes, data centres and more. Our generator installs power critical systems like refrigeration, IT, and emergency lighting - with minimal disruption.
We deliver backup power for schools, council offices, and NHS sites - all designed to current UK regulations, with optional maintenance plans for ongoing reliability.

Common Questions About Generator Backups
A: Yes. Emergency lighting helps people exit safely during a power cut – but a generator keeps critical systems like IT, security, refrigeration, and communications running.
A: Most systems start automatically within 10 – 20 seconds. If paired with a UPS (Uninterruptible Power Supply), there’s no disruption at all – your power stays on seamlessly.
A: Absolutely. We can configure your generator to cover only key circuits – such as servers, alarms, lighting or cold storage – helping reduce installation size, running time, and fuel costs.
A: Low-noise and hybrid generator models are available. Some projects may need planning consent, but many fall under permitted development. We’ll advise based on your location and setup.
A: We calculate this during your site survey, based on your essential systems and usage. You’ll get a tailored recommendation with the right kVA rating for your site.
