If your site in Erith needs dependable temporary power, we’re ready to support you with generator hire that fits the job. From planned works to emergency outages, our hire solutions help keep your operations running without delay.
With generator units ranging from 20 kVA to 1250 kVA, we supply power for everything from small utility works to multi-MW construction demands. All equipment is delivered fast, installed safely, and maintained by our in-house team.
We stock an extensive fleet of diesel generators across key sizes: 20 kVA, 60 kVA, 100 kVA, 200 kVA, 500 kVA, and 1250 kVA. This means you get access to the right capacity, whether you’re running lighting rigs or supporting entire site operations.
Generators can be synced or used individually, depending on load requirement and runtime. We also support parallel configurations where backup or redundancy is needed for sensitive sites.
Units are delivered fuel-ready, sound-attenuated, and fitted with efficient load-sharing controls to prevent overuse or risk of failure.
We operate across Erith and surrounding areas with 24/7 delivery availability. Our tracked fleet includes flatbeds, HIABs, and crane-assisted vehicles to suit any site entry point or terrain.
Whether it’s a high-street shop front or a gated industrial compound, we plan delivery around your site access and timing. For planned maintenance or seasonal usage, we schedule early to avoid last-minute disruption.
Emergency breakdown? We prioritise same-day response and can have a generator onsite within hours depending on availability and access.
All generator installs are handled by certified professionals. We take care of cabling, distribution boards, load testing, and any auxiliary components required for smooth handover.
Every install follows NICEIC and Gas Safe standards, ensuring electrical safety, emissions compliance, and noise level control. Our engineers remain on-call for post-install checks and refuelling support if required.
For longer-term use, we also provide fuel management and scheduled servicing so your setup remains stable and efficient.
