Electric shower installation pricing factors
Shower electrical pricing reflects the physical work and materials needed to ensure your appliance runs safely and compliantly.
From £220
Included when agreed
- Checking the existing circuit and breaker against the shower rating
- Connecting the shower and fitting or replacing the pull cord isolator
- Testing and a certificate for the work
Ways to pay
- Pay by bank
- Bank transfer
- The base price covers the electrical connection of a replacement shower onto a verified, suitably sized existing circuit, including the replacement of a standard ceiling pull cord switch.
- Upgrading to a higher-kilowatt shower that demands a thicker supply cable or a newly routed circuit back to the fuse board requires additional materials and time, which are quoted clearly before work starts.
- Plumbing adjustments, replacement of the physical shower unit itself, and any necessary consumer unit upgrades or additional residual current protection are priced separately.

What happens on the day
Shower installation visits are planned to test your existing supply, connect the appliance securely and issue the necessary paperwork with minimal disruption.
- Initial circuit and consumer unit checksWe inspect your fuse board to verify the breaker rating, check for residual current device protection and assess the conductor cross-section of the shower cable before any mechanical work begins.
- Isolator fitting and terminal connectionsThe unit is wired into the bathroom isolator switch, whether that is a ceiling-mounted pull cord or an adjacent switch outside the wet zone, before making secure, sealed terminal connections inside the unit casing.
- Live testing under full electrical loadThe shower is powered up and tested on maximum heat settings to verify that the circuit carries the full electrical draw stably, confirming correct voltage drop and rapid trip times for protective devices.
- Handover and certificate productionOnce checks confirm safe operation, we provide the appropriate minor works or electrical installation certificate and explain how to use the local isolator safely when leaving the property empty.

WhatsAppCan I replace my existing electric shower with a more powerful model?
Only if your existing cable and fuse board breaker can handle the increased electrical demand. An 8.5kW shower can often use a 6mm cable, but upgrading to a 9.5kW or 10.5kW unit usually requires a 10mm cable and a 45A or 50A breaker. We inspect the cable diameter and circuit length before connecting a larger unit.
Do I need a qualified electrician to install an electric shower?
Yes. Bathrooms are designated as special locations under UK wiring standards due to the increased risk of electric shock in wet environments. The installation, isolation switch and circuit protection must be tested with calibrated instruments and covered by an official electrical certificate.
Why does my electric shower pull cord switch smell hot or feel warm?
A warm or burning pull cord switch usually indicates loose terminal screws or an isolator switch rated lower than the shower current. Electric showers draw heavy currents for long periods, which will overheat loose connections. The switch should be isolated at the fuse board and replaced with a correctly rated 45A or 50A unit.
Does an electric shower require its own circuit?
Yes. An electric shower must always be fed by an independent radial circuit running straight from the consumer unit. It must never share a circuit with sockets, immersion heaters, lighting or other kitchen appliances.
Do you handle both the plumbing and the electrical work?
Our service covers the electrical installation, including circuit testing, cabling, pull cord isolators, terminal connection and compliance certification. Connecting to the water supply pipework is straightforward during like-for-like replacements, but extensive plumbing changes or tiling work remain separate.
