When to replace a light switch or dimmer
A light switch or dimmer needs replacing when it crackles, sticks, grows hot, or no longer turns the lights on and off as it should.
- A switch that sparks or sticksSparks, a spongy click or a rocker that will not stay put mean the mechanism inside is worn.
- A dimmer that buzzes or drops outA dimmer is the knob or slider that sets how bright the lights are, and buzzing or flicker means it is failing.
- A cracked or loose faceplateA broken plate or a fitting that moves on the wall leaves live parts closer to a hand than they should be.
- A switch that no longer suits the roomYou may want a dimmer where there is only an on off switch, or a plate that matches the rest of the room.
What happens on the day
The old switch or dimmer comes off, a new one goes on, and you try the lights before we leave.
- Arrival and isolating the lightsThe lighting circuit that serves that switch is isolated so the existing control can come off the wall.
- Fitting the new controlThe new switch or dimmer is wired onto the existing conductors and seated on the back box.
- Testing and any certificate you bookedYou try the lights and, when a minor works certificate was booked, that document is completed before we go.

“Ten years on Colchester housing stock and I have seen most of it: terraces where the lighting circuit has been extended once too often, boards fitted before RCDs were standard, new builds with sockets nowhere near the kitchen. I check the earthing, the bonding and whether the supply will carry another load before I price anything, because the age of a house settles nothing on its own.”

How much does a light switch or dimmer replacement cost?
The starting price is £60 for one light switch or dimmer. That figure is for a single fitting in the existing back box. After you book, the old control comes off and the new one goes on during the visit.
Do you replace dimmers as well as ordinary light switches?
Yes, Lighting Electrical replaces both light switches and dimmers. A dimmer is the control that sets how bright the lights are. The £60 starting price applies to one replacement of either type.
Will the lights be off while the switch is changed?
The lighting circuit that serves that switch is isolated while the fitting is swapped. Sockets, cookers and other circuits stay on. Power to those lights returns once the new control is on and tested.
Do I get a certificate for a switch replacement?
A minor works certificate is a separate item from £95, not part of the £60 starting price. Add it to the booking if you need written confirmation of the work on that circuit. The visit still finishes with the lights working from the new control.
Can you change a switch for a dimmer?
Yes, an on off light switch can be replaced with a dimmer where the wiring and the bulb can work with one. If the back box or the bulb will not take a dimmer, the price is given in writing before the new fitting goes on. The starting price of £60 is for that swap when the existing box and wiring already suit the dimmer.
