Lighting scenes
Every circuit dimmable and grouped into scenes you set once: cook, read, film, away.
Kelvin House, smart-home installers in Leeds and West Yorkshire. One plate by the front door. Behind it, every lamp, radiator, blind and lock in the house — wired once, set up around how you live, and looked after for as long as you live there.
- Wired in six to ten working days
- Set up and explained room by room
- Ten years of aftercare, included
Book a home surveyHow a job runs
Five systems, one plate
Each works on its own and better together. We fit what the house needs now and wire for the rest.
Heating and cooling
Each room on its own schedule, learning how fast it warms, radiators and underfloor in one app.
Blinds and shading
Motorised blinds and curtains that follow the sun, close at dusk and open quietly before the alarm.
Security and access
Keypad and phone entry, cameras you can trust, and a house that locks itself when the last person leaves.
Sound and networks
Ceiling and shelf speakers in any room, on a wired network with Wi-Fi that reaches the loft.
Recent houses
Four of the 320. Every one is still on our aftercare list.
One plate, four scenes
The same room, set by one press. We build each scene with you, then the house runs it on time.
- 06:45
Morning
Blinds lift to half, the bathroom floor is already warm, kitchen lights come up cool and bright.
- 08:30
Away
One press by the door: lights off, heating to eco, south blinds down, alarm set.
- 18:40
Evening
Lamps warm to amber, the hall dims to a glow, blinds close as the street lights come on.
- 23:15
Night
Everything off but a low path to the landing, doors locked, heating down to seventeen.
How a job runs
Four steps from the first visit to the day the house runs itself. One team the whole way.
-
Survey
A free walk round the house with an engineer: rooms, routines, the wiring and where the Wi-Fi gives up.
-
Design
Drawings, a device schedule and a fixed quote within five working days. Change anything before we start.
-
Install
First fix while walls are open, second fix and setting up after. Our own engineers, no subcontractors.
-
Handover
We set the scenes with you, room by room, and leave the house learning your week.
After the van leaves, the house stays on our list.
Every Kelvin House home is watched, tuned and visited. One number, a named engineer, and a same-week call-out when something needs hands.

Day one
Handover walk-through
Every plate, every app, every scene, until it feels obvious to everyone in the house.
Week two
A call to tune
Schedules moved to the routine you actually keep, not the one you guessed at.
Month three
Ready for winter
Heating curves and blind times shifted as the days get shorter.
Every night
Remote health check
Each controller, battery and access point checked while you sleep. Most faults are fixed before you notice.
Year one
Annual visit
Firmware, batteries and a fresh look at what you use and what you never touch.
Year ten
Still on the list
Parts and labour covered for ten years, then a plan if you want one.

Fixed prices after the survey. Every plan grows into the next without rewiring.

Living with it
Five households, a year or more after handover.
-
“We set the evening scene once. Two winters on, nobody touches a switch after six.”
Hannah BellChapel Allerton
-
“The survey found three things our builder had missed. The quote never moved.”
Marcus OdellRoundhay

“Ian wanted fewer remotes. Now there are none, and the heating bill fell by a third.”
Pat and Ian FirthOtley
-
“They wired a rented flat without chasing a wall, and moved it all when I left.”

“The mill walls are a metre thick. Theirs is the first Wi-Fi that works upstairs.”

Questions
What people ask on the survey, answered before it.
Do you need to chase walls or lift floors?
In most homes, no. We use existing back boxes and ceiling voids, and wireless controls where a cable cannot reach. New builds and renovations get a fully wired system while the walls are open.
What happens if the internet goes down?
Everything keeps working. Scenes, schedules and plates run on a controller in the house; the internet only adds the app away from home and our remote checks.
Can we keep our switches and radiators?
Usually. Most radiators take a smart valve in minutes, and we can fit dimmers behind your current plates or match new plates to them.
How long does an install take?
Essentials takes about three days on site. A whole house is six to ten working days, phased so you can live there throughout.
Are we tied to you afterwards?
No. We choose open, well-supported systems and explain why in your design. At handover you get every password, drawing and device list.
What does aftercare cost after ten years?
Year eleven onwards is an optional plan at £14 a month, covering remote checks, the annual visit and call-outs.
