Diesel Generator for House | Silent Backup Power UK

Diesel Generators for Your House — Silent Backup Power

Power cuts in the UK are becoming more frequent and lasting longer. A silent diesel generator gives your house reliable backup power whenever the mains goes down — keeping your heating, fridge, freezer, lights, and internet running while your neighbours sit in the dark.

Why Diesel for Home Backup?

Diesel generators are the most reliable and cost-effective backup power solution for UK homes. Unlike petrol generators, diesel engines are built for sustained running, use less fuel, and last significantly longer. Unlike battery storage, a diesel generator provides unlimited runtime — as long as there's fuel in the tank, you have power. And unlike solar panels, they work at 2am in January when you actually need them most.

What Size Generator for a House?

5kVA (4kW): Essential circuits — lights, fridge, freezer, boiler, phone chargers, TV. Perfect for basic backup during short outages.

8-10kVA (6.5-8kW): Full house coverage — everything above plus electric shower, washing machine, microwave, and multiple rooms. Our most popular home size.

15-20kVA (12-16kW): Large homes or homes with electric heating, hot tubs, workshops, or multiple high-draw appliances running simultaneously.

Silent Operation for Residential Areas

All our home generators come with soundproof canopies. They're quiet enough to run in a residential area without disturbing neighbours — comparable to a normal conversation at 7 metres distance. No planning permission is typically required for a portable generator used for temporary or backup power.

How to Connect a Generator to Your House

For home backup, we recommend having a qualified electrician install a changeover switch. This lets you safely switch your house from mains to generator power in seconds during an outage. It's a straightforward job for any competent sparky and keeps everything safe and legal.
