Why wired beats battery
Smart devices are only as good as the power behind them. A battery video doorbell that needs charging every few weeks, or a camera that dies in cold weather, quickly stops being convenient. A properly wired device, fed from a real supply, just works, all year, with nothing to recharge. We install smart home devices and video doorbells across Kent, with the power side done properly.
Most of what we fit comes down to giving a smart device a reliable, tidy supply: the right transformer for a doorbell, a fused spur for a hub, or the correct switch for smart lighting.
Video doorbells and transformers
Wired video doorbells need a transformer that delivers the right voltage and power for the model. Many homes have an old doorbell transformer that’s the wrong rating for a modern video unit, which leads to dropouts, poor video, or a doorbell that won’t charge its internal battery.
We supply and fit the correct transformer and a tidy wired connection, so the doorbell has a constant supply and works reliably rather than fighting for power. Where there’s no existing doorbell wiring, we run a neat supply to the door.

Smart switches and the neutral question
Smart light switches are popular, but many need a neutral conductor at the switch position, and older switch drops often don’t have one. Whether a particular smart switch will work comes down to what’s behind your faceplate.
We check before fitting and advise honestly: some setups are straightforward, some need a different switch or a small wiring change, and we’ll tell you which yours is rather than leaving you with a device that won’t commission. See also light switches and dimmers.
Power for cameras, hubs, and panels
Smart homes accumulate gadgets that all need power: a hub by the router, cameras around the eaves, a panel in the hall, sensors here and there. Done piecemeal, that’s a tangle of plug-in adaptors. Done properly, it’s tidy fused supplies in the right places.
We add fused spurs and supplies for hubs and panels, and weatherproof outdoor power for cameras and sensors, so the system is reliable and there are no chargers dangling off sockets.

How a smart install runs
Tell us the device and where it’s going. We confirm the supply, transformer, or neutral it needs, install and connect it on a tidy, fused supply, then test it and help with the first setup so it’s working before we leave.
It’s all quoted up front, and we’re happy to do a single doorbell or a whole set of devices.

Frequently asked questions
Is a wired video doorbell better than a battery one?
For reliability, yes. A wired doorbell on the right transformer has constant power, with nothing to recharge and no cold-weather dropouts. We fit the correct transformer and a tidy wired supply so it just works year round.
Will smart switches work with my existing wiring?
It depends what's behind the faceplate. Many smart switches need a neutral conductor at the switch, which older switch drops don't always have. We check before fitting and advise honestly on what will work with your wiring.
Can you fit a transformer for my video doorbell?
Yes. Many homes have an old doorbell transformer that's the wrong rating for a modern video unit, causing dropouts or charging problems. We supply and fit the correct transformer and a tidy wired connection so the doorbell has a constant supply.
