About Us

Established in 1985, Stephill Generators Ltd are based in a 40,000 square foot HQ and manufacturing facility centrally located in Wellingborough, Northamptonshire. The company is the UK’s largest volume manufacturer of portable petrol and diesel generating sets from 2 to 117kVA, pre-dominantly supplying generators to the hire and construction sector, but also producing a wide range of products for event, utility, leisure and standby applications. The Stephill name is synonymous with quality and reliability, and the companies strict policy in only using premium brand components in its products has firmly cemented its position as the market leading supplier of portable generators to plant and tool hire companies both large and small. Though always producing competitivly priced products, we always have – and always will - resisted the risk of diluting our strong brand name by incorporating inferior / low cost components in our generator builds. The companies edict of “buy a Stephill and only buy it once” is as relevant as ever, particularly to those who decide to purchase a cheaper / inferior alternative product which lets them down after only a short period of use.

With a wealth of knowledge and experience built up in over 30 years, Stephill offer one of the widest ranges of generators, designed and built to withstand the harsh environments of the rental sector. When buying a Stephill generator, our clients can be sure that they will maximise revenue by adding the most reliable and durable and versatile portable power product to their hire fleet. By understanding the unique requirements of the hire industry, we are able to supply generators on an ex-stock - or very short - lead time, and our experienced sales and technical staff are always on hand to assist and advise, resulting in delivery of the right generator for each and every application.
