Electric Showers

Electric showers are a popular choice in UK homes because they heat water instantly using an internal heating element, meaning you do not need a hot water cylinder or combi boiler supply to get a hot shower. Because they combine water and electricity in one appliance, correct selection, safe wiring, and proper commissioning are essential to prevent nuisance tripping, poor performance, or dangerous faults. An electric shower install is not just a simple swap. A professional will check water pressure and flow, identify the unit rating (typically 8.5kW to 10.5kW), confirm your consumer unit has suitable spare capacity, and verify that the circuit cable size, isolation switch, and protective devices are correct for the load and the cable run. If your existing shower was lower powered or installed years ago, the circuit may need upgrading to meet modern safety expectations. TradeSupermarket helps you find trusted electricians who regularly work on electric showers, including like-for-like replacements, upgrades, and fault finding. Listings make it easy to compare availability, experience and customer feedback, so you can choose a specialist who will advise on the right shower for your bathroom and budget, and complete the work with minimal disruption. For peace of mind, always use a properly insured electrician who understands the requirements of BS 7671 (IET Wiring Regulations) and the special rules for bathrooms (zones, IP ratings, and isolation). A safe installation should include appropriate RCD protection, correct bonding considerations, a suitable local isolator, and careful sealing and plumbing connections to reduce the risk of leaks affecting electrics.
