Final costs depend on your existing wiring, consumer unit capacity, and plumbing layout. - Electric shower installation and replacement: £150 - Covers the electrical disconnection, replacement, and testing of a direct like for like unit. - Applies where existing cable sizing, circuit protection, and isolation switches meet current electrical standards. - New circuit runs, cable upgrades, and consumer unit modifications are quoted separately. - Shower units and plumbing fittings are supplied by the customer or quoted as separate materials. ## Match the shower to the property Installing an electric shower requires correct cable sizing, adequate consumer unit capacity, and appropriate water supply pressure. - **Direct replacements:** Swapping an existing shower for a unit of identical kilowatt rating in properties across Parkstone and Broadstone is straightforward when existing cables and switches are undamaged. - **Power upgrades:** Upgrading from an older low kilowatt unit to a higher output model often requires larger cable and upgraded circuit breakers to prevent overheating and nuisance tripping. - **New bathroom circuits:** Adding a new electric shower in older properties across Wimborne Minster or Wareham requires a dedicated radial circuit from the consumer unit with RCD protection. ## What the installation covers Every electric shower replacement or installation follows strict safety and verification procedures. ### Included when agreed - Safe electrical isolation of the existing shower circuit - Assessment of cable cross-sectional area and circuit breaker ratings - Mounting the shower unit securely to the bathroom wall - Connection to existing suitable electrical supply and cold water pipework - Inspection of the ceiling pull-cord or local isolation switch - Full electrical testing including earth continuity and insulation resistance - Operational checks for correct heating and water flow ### Not included automatically - Extensive plumbing alterations or main supply pipe rerouting - Tiling, plastering, or cosmetic bathroom repairs - Upgrading undersized supply cables across the property - Consumer unit replacements or major distribution board repairs ## How the installation works Here is what happens during a standard electric shower installation visit. 1. **Access and isolation:** Please clear personal items from the shower cubicle. We locate the main consumer unit, isolate the bathroom circuit, and verify the power is off. 2. **Mounting and connection:** We remove the old unit, check the existing supply cable and pipe alignments, secure the new shower to the wall, and make all electrical connections. 3. **Testing and commissioning:** We test the electrical circuit under load, inspect RCD trip times, run water through the unit, and check all seals before handing over the controls. ## What you receive Following the installation, you receive full documentation confirming safe operation. - **Installed shower:** A securely fitted and fully functioning electric shower connected to your cold water and electrical supplies. - **Tested electrical work:** Verification that earth loop impedance, RCD protection, and cable loads meet British Standard requirements for bathroom zones. - **Relevant documents:** An electrical installation certificate or minor works certificate covering the work completed on your bathroom circuit. - **Clear next steps:** Guidance on basic maintenance, cleaning the filter and handset, and operating the isolation switch correctly. ## Electric shower questions Common questions about electric shower installations and replacements in domestic properties. ### Can I replace my electric shower with a more powerful model? I will inspect your existing cable thickness and consumer unit fuse first. Higher kilowatt showers draw higher currents, which often require thicker 10mm cable and an upgraded circuit breaker to operate safely. ### Do you supply the shower unit itself? I am happy to install a unit you have purchased, provided it suits your existing electrical supply and pipe entry points. Alternatively, I can supply a suitable shower and confirm the materials cost before starting. ### Why does my shower need an isolator switch? Bathroom electrical regulations require a local isolation switch, typically a ceiling pull cord outside the shower cubicle or a wall switch outside the room, so the power can be safely isolated without turning off the entire house. ### Does an electric shower require RCD protection? Yes. Current wiring regulations require all circuits supplying equipment in bathrooms to have 30mA RCD protection to reduce the risk of electric shock in wet environments. ## Official electric-shower guidance Official guidance covering electrical safety in domestic bathrooms and statutory compliance. - [Electrical safety in bathrooms](https://www.electricalsafetyfirst.org.uk/safety-advice/home-and-people/bathroom/): Safety advice and regulations regarding electrical equipment, switches, and special installation zones in wet rooms. - [Building Regulations approval for electrical work](https://www.gov.uk/building-regulations-approval/when-you-need-approval): Official rules detailing when new domestic electrical installations require building control notification. ## Business facts - Based: Aldhelms Road, Poole, BH12 1AE - Service area: Poole, Bournemouth, Broadstone, Wimborne Minster, Wareham, Parkstone, Ferndown, Christchurch, Canford Heath, Westbourne - Hours: Every day 00:00–23:59 - Phone: +447397844504 - Email: info@mx2-electrical-ltd.co.uk - Insurance: Public liability £2,000,000 - Qualifications: Nvq level 3, City&Guilds; Gold Card Electrician - Pricing rules: Current labour rate: £70 per hour.; Materials, specialist equipment and larger project work are confirmed separately before they go ahead. ## Request a quote - [Start a request](https://mx2-electrical-ltd.co.uk/#chat): Send the job details and postcode to MX2 Electrical. ## Related pages - [EICR](https://mx2-electrical-ltd.co.uk/services/eicr): EICR testing and electrical safety reports. - [Fuse board replacement](https://mx2-electrical-ltd.co.uk/services/fuse-board-replacement): Consumer unit and fuse board replacement. - [EV charger installation](https://mx2-electrical-ltd.co.uk/services/ev-charger-installation): Home and workplace EV charger installation. - [PAT Testing](https://mx2-electrical-ltd.co.uk/services/pat-testing): PAT testing for landlords and businesses. - [Electrical Fault Finding & Repair](https://mx2-electrical-ltd.co.uk/services/electrical-fault-finding): Find and repair electrical faults. - [Full sitemap](https://mx2-electrical-ltd.co.uk/sitemap.md): Complete machine-readable page directory.
