Upgrades that work with your existing wiring
Most smart home upgrades replace or add to what is already in your walls. A smart dimmer goes in where your old switch was, a smart thermostat connects to your existing heating wiring, and a set of interlinked alarms can take power from circuits you already have.
Because the work uses your existing circuits, there is no new circuit from the consumer unit and usually very little disruption. Before recommending anything, we check the condition of the circuit, the depth of the back box and whether a neutral is available, so the products you choose will actually work in your home.
What we can fit
Smart switches and dimmers
Swap standard switches for smart switches and dimmers that work from the wall, an app or your voice. We help you choose products that suit your lamps, as LED compatibility and minimum load matter for smooth, flicker free dimming. We can fit products that work with Apple Home, Google Home, Amazon Alexa and Matter.
Wireless lighting control retrofits
Wireless modules and keypads let you add lighting control without chasing new cables into finished walls. A module fitted behind an existing switch or at the light, paired with a wireless keypad, can add a second switching position, set scenes or group lights across a room.
Video doorbells
A wired video doorbell does not rely on batteries you need to keep charging. We can connect it to your existing bell transformer or fit a new transformer fed from a nearby existing circuit, replace or connect the chime, and check the Wi-Fi signal at the door before fitting.
Interlinked smoke and heat alarms
Mains powered alarms with battery backup, interlinked so that when one sounds they all sound. A typical layout puts smoke alarms in hallways and landings and a heat alarm in the kitchen, following the positioning guidance in BS 5839-6. Radio interlinked alarms avoid running cable between floors.
Smart thermostat wiring
We wire smart thermostats and their receivers to your existing heating controls, replacing an old room thermostat or programmer. We handle the electrical connections only and do not work on the gas side of the boiler.
USB and decorative accessory upgrades
Replace tired switches and sockets with USB-A and USB-C sockets, screwless plates or decorative finishes such as brushed brass, black nickel or stainless steel. Matching accessories throughout a room or a whole floor is a simple way to lift a space.
How we approach smart upgrades
We start by asking what you want each upgrade to do, then check your existing wiring and back boxes to confirm which products will fit. On the day we install, pair each device with its app, set up any scenes or schedules, test everything and show you how it works. The aim is a home that everyone in the household can use, not just the person who set it up.
Smart home upgrades are limited to work on your existing circuits. If something you want would need a new circuit or a change at the consumer unit, we will say so at the survey stage.
Pricing guidance
The cost depends on the products you choose, how many devices you want and what your existing wiring allows. We provide a clear quote after checking your wiring and talking through the options, before any work starts.
Frequently asked questions
Do I need a neutral wire for a smart switch?
Many smart switches and dimmers need a neutral at the switch position, and older homes often do not have one there. Some products are designed to work without a neutral, and wireless modules fitted at the light itself are another option. We check what is behind your existing switches before recommending a product, so you only buy something that will work in your home.
Do smart home upgrades need a new circuit or Building Control notification?
Not the upgrades on this page. Replacing accessories such as switches, sockets and thermostats, and adding to an existing circuit outside a bathroom or other special location, is not notifiable under Part P in England. Everything we offer here works on your existing circuits. If your plans would need a new circuit or a change at the consumer unit, that falls outside this service and we will tell you before any work starts.
Can you fit a video doorbell if I do not have a wired doorbell?
Yes. A wired video doorbell needs a low voltage supply, which we can provide with a doorbell transformer fed from a nearby existing circuit. We route the cable as neatly as the building allows and check the Wi-Fi signal at the door before fitting, as a weak signal is the most common reason video doorbells disappoint.
Can mains smoke alarms be interlinked without running cable between rooms?
Yes. Radio interlinked mains alarms connect to a nearby existing circuit for power and talk to each other wirelessly, so when one alarm sounds they all sound. This avoids running interlink cable between floors and is often the tidiest option in a finished home. Each alarm has a battery backup in case the power goes off.
Should I choose smart switches or a lighting control system?
Smart switches are a good fit for upgrading a room or two, or for adding app and voice control to lights you already have. If you want whole home control with dedicated keypads, carefully programmed scenes and one system that ties every room together, a Lutron or Rako lighting control system is the premium option. We can talk you through both.
Which smart home system should I choose?
It depends on what you already use. If your household uses iPhones, Apple Home is a natural fit, and Google Home and Amazon Alexa are also widely supported. Products that support Matter can work with more than one of these. We can advise on compatible products, and we are not tied to any single manufacturer.
Will my smart switches still work if the Wi-Fi goes down?
With wired smart switches, yes. They carry on working as normal switches and dimmers from the wall. You lose app and voice control until the connection returns, but the lights themselves keep working.
