About this service
What we do and who this is for
A shower isolator switch is the switch that cuts the power to your electric shower, usually a ceiling pull-cord or a wall switch. Because it carries a heavy current every time the shower runs, it's one of the most common electrical parts to wear out, and a worn one is a genuine fire risk.
We replace faulty shower isolator switches across Nottingham and the East Midlands, on any electric shower, whether it's a pull-cord or wall-mounted switch. The usual signs are a stiff or snapped pull cord, a buzzing or crackling noise, a burning smell, scorch marks, or the shower cutting out. A loose or overheating shower isolator is one of the faults our electricians most often flag on EICR inspections, so it's not something to leave.
Our NICEIC-approved electrician isolates the circuit, fits a new double-pole switch rated to match your shower, checks the connections and cable, and tests everything before leaving. Most jobs take under an hour, at a fixed price, with same-day and 24/7 emergency slots available. If the switch is discoloured, warm or smells of burning, stop using the shower and book a same-day visit.

Frequently asked questions
Common questions before you book
It's the switch that isolates the power to your electric shower, so it can be safely turned off for use or maintenance. It's usually a ceiling-mounted pull-cord switch in the bathroom, or a wall switch fitted just outside it.
Yes. An electric shower must have a means of isolation on its own dedicated circuit. Inside a bathroom this has to be a ceiling pull-cord switch, or a wall switch located outside the room.
Yes, it's designed to be left on and only switched off for maintenance or when you're away. But if the switch buzzes, feels warm or smells of burning, turn it off and get it replaced.
You don't need to. Leaving it on is fine for normal use. Only switch it off if there's a fault or you're away for a long period.
No. A switch that gets warm is a warning sign that the contacts are worn or the switch is underrated for the shower. This is a fire risk and should be replaced quickly.
Usually the internal contacts are worn or the pull-cord mechanism has failed. Buzzing, a stiff cord or the shower not switching on all point to a switch that needs replacing rather than repairing.
No. It must be replaced by a qualified electrician to be safe and meet the wiring regulations.
We charge a fixed price for the switch supplied and fitted, with same-day availability across Nottingham and the East Midlands. See the price above.
