The UK's leading Technical Experts in Standby Power, Uninterruptible Power Supplies and Combined Heat & Power Systems.

We design, supply, install and maintain prime power and standby power generators, combined heat and power systems (CHP systems) and uninterruptible power supply systems (UPS systems).

We keep companies – of all sizes, across every industry and in any UK location, no matter how remote – fully functioning in the face of mains power failure or the ongoing absence of available mains power.

We’re a family-owned and family-run business that brings the best of the small business ethos – genuine, caring customer relationships and pride in our work – to a big business environment. We’re big enough, knowledgeable enough and agile enough to count industry leaders among our clients, but affordable and accessible enough to keep small companies, such as independent care homes, just as happy.

Celebrating nearly 40 years in business, we’re proud to say that our standby power generators and UPS systems have provided the continuous power which hasn’t just saved businesses their livelihoods, data and reputation, but has saved lives.

Our network of generator service depots, refuelling stations and power generator engineers guarantees fast access to prime power, CHP design and installation and planned and emergency backup power anywhere in the UK.

The nerve centre of shentongroup operations is Shenton House in Andover. It’s from here we support our 18 nationwide depots and network of power generator engineers. Our 24/7 emergency call-out desk is based here, monitoring national news and power supplies and offering our clients reassurance, technical support and engineer dispatch.

We guarantee to deliver power to your door within three hours.
