National construction equipment hire and services provider Speedy, has delivered an industry-first retrofitted Stage V emission compliant generator, as part of a trial to help boost the availability of greener generators to the construction industry.

The business is working with exhaust systems specialist Eminox, a global leader in the design of aftermarket retrofit technology, becoming the first in the industry to retrofit Stage IIIa generators to Stage V emission compliant standards.

Some major infrastructure and construction projects require equipment to meet Stage V emission standards to lower the impact on air quality. Compliant engines limit the overall volume of harmful pollutants, such as nitrogen oxide and carbon monoxide in exhaust gas, and are compatible with hydrotreated vegetable oil, which emits up to 90% less CO2e than red diesel.

Following successful trials, Speedy has invested £1 million in upgrading its Stage IIIa generators to Stave V emission compliance.


Nick White, UK sales director – power, at Speedy, said: “All major contractors are looking for Stage V generator technology as they strive to support sustainably ambitious projects, that goes above and beyond the current legislation on environmental impact. But demand is massively outweighing supply, with low availability blocking contractors from switching to greener power alternatives.

“We’ve invested millions of pounds in our Stage IIIa fleet over the last few years. Retrofitting these units to the increasingly essential Stage V emission compliant standard will help to deliver the capacity the market needs, while ultimately enabling contractors to operate more sustainably.

“Upgrading generators, rather than replacing, will also cut tonnes of waste in our business as Stage IIIa is phased out in the years to come. We’re looking forward to working further with Eminox on this initiative and on new projects to come.”


Speedy’s power team was recently appointed by the Department for Business Energy and Industrial Strategy to ship 287 mobile generators to Ukraine. Speedy sourced and supplied the units from manufacturer Pramac, with the generators being used to maintain power for essential services like hospitals and shelters.

Speedy is the UK’s leading provider of tools, equipment, and plant hire services to a wide range of customers in the construction, infrastructure and industrial markets, as well as to local trade and consumers. It operates from 200 sites across the UK and Ireland.
