Generator installation in Monmouth keeps your home or business running through a power cut. We fit the changeover switch and wiring so a backup generator can be used safely, with a free quote first.

A generator must never be connected straight into a socket or the consumer unit. Power could flow back down the mains cable and put network engineers at risk. A changeover switch disconnects your home from the grid before the generator takes over.
A portable generator plugs into a weatherproof inlet on the outside wall and is switched over by hand. A standby generator is fixed in place and can start automatically when the power goes. We'll help you weigh up cost, convenience and how often you lose power.
Most generators can't run everything at once. We help you decide which circuits matter most, such as the fridge, freezer, heating controls, lighting and a few sockets, then wire the changeover so those circuits are powered when the mains fails.
We start by asking which appliances and circuits you need during a power cut and the size of generator you have or plan to buy. We check the consumer unit and earthing, then give you a free quote for the changeover switch, inlet and wiring.
On the day, the power is off while we fit the changeover switch and connect the inlet or standby unit. We test the switchover with you, show you the safe order for starting and stopping the generator, and give you a certificate for the work.
Ring us or send a few details about the job. We aim to respond the same day, with no call-out charge.
We come and look at the work, then give you a free quote with no obligation to go ahead.
We finish the job, test every circuit we've worked on and leave you with the right certificate.
No. Back-feeding a generator through a socket is dangerous. It can make the mains cable live while engineers are working on it, and can damage your installation. The safe way is a changeover switch and inlet fitted by an electrician.
It depends on what you want to run. Essentials like lighting, a fridge, a freezer and heating controls need far less than electric cookers, showers or heaters. We'll help you list the loads and suggest a size, or check that the one you have is suitable.
Yes. Properties at the end of long overhead lines can lose power for longer, and farms often need to keep water pumps, chillers or animal equipment running. We can wire a changeover for those circuits so a generator takes over safely when needed.
Most changeover and inlet installations take around a day, depending on where the generator will sit and how far the cable runs. A standby generator with automatic switching takes longer. We'll give you a realistic timeframe when we send the quote.
We fit generator changeovers for homes, farms and businesses across these areas.
