Cleaner Generator Hire in London
London’s emissions standards are tightening. MEMS Cleaner Options give London businesses access to lower-emission generation without compromising on performance or reliability.
Stage V Generators | Our Stage V compliant generators meet the latest emissions regulations and are ideal for sites within or near the ULEZ, same power output, significantly reduced particulate and NOx emissions.
HVO Fuel | MEMS offers HVO as a direct drop-in replacement for diesel. Made from 100% renewable waste materials, it has the potential to reduce greenhouse gas emissions by up to 90%.
Battery Hybrid Systems | Our battery energy storage systems work alongside generator sets to cut fuel use, reduce emissions, and minimise noise, particularly valuable on London’s dense urban sites.

MEMS in London: Case Studies
Tower of London
A switchboard failure at one of London’s most iconic landmarks required emergency power within 3 hours. MEMS delivered a 300 kVA solution that ran 24/7 for over 12 weeks without a single failure.
Holborn Fire
When a fire in an underground utilities tunnel cut power to 5,000 London homes and businesses, MEMS was on site in just over an hour, ultimately deploying 52 generators to restore power across the West End.
London Financial District
An HV network fault at a major commercial estate in London’s financial district required immediate backup power. MEMS supplied a 1250 kVA solution and ran 24/7 for two months without interruption.
