Electric shower installation NW6
Part P registered electricians installing and replacing electric showers across the NW6 postcode — West Hampstead & Kilburn, London. From £350 for replacement, £550 for new installation with cable run. Same-day available.
Why electric showers suit NW6 properties
Independent of your boiler — ideal for West Hampstead & Kilburn flats
Electric showers draw cold water directly from the mains and heat it on demand — no stored hot water, no reliance on the boiler. For NW6 flats and converted properties where a combi boiler cannot sustain multiple simultaneous hot water draws, an electric shower eliminates the contention entirely.
The installation requires only a cold water supply connection and a new dedicated circuit from the consumer unit. We size the cable to the unit: 6mm twin-and-earth for 8.5kW and 9.5kW models, 10mm for 10.8kW. RCD or RCBO protection is fitted on every circuit, and we handle Part P Building Regs notification to your local authority. You receive an electrical installation certificate and a Building Regs completion notice.
Thermostatic electric showers are the recommended choice for NW6 mansion blocks and high-rises where shared mains risers cause pressure variation. A thermostatically controlled unit maintains a stable outlet temperature regardless of fluctuations elsewhere in the building — eliminating the scalding or cold surge risk of standard single-control models.
What we install
Electric shower services
8.5kW standard shower
Entry-level electric shower ideal for properties with lower mains pressure. Suitable for older London flats where a 6mm supply cable is already present. Reliable flow for everyday use.
9.5kW mid-range shower
The most popular choice for London households. Improved flow rate over 8.5kW units, operates independently of the boiler, and typically runs on a 6mm cable from a dedicated 40A MCB.
10.8kW high-power shower
Maximum flow rate for electric showers. Requires a 10mm supply cable and 45A RCD-protected circuit. Recommended for family homes and properties with good mains pressure.
Like-for-like replacement
Swap an existing electric shower unit onto the current supply cable and circuit without new cabling. Fastest and most cost-effective option where the existing wiring meets current regs.

What kW electric shower do I need in NW6?
