Electric shower installation in Hackney

Electric showers draw cold water directly from the mains and heat it instantly using an internal heating element. Unlike mixer showers or thermostatic bar valves, they need no stored hot water and place no demand on your boiler. For the millions of London flats running on combi boilers with limited simultaneous hot water output, an electric shower removes the conflict entirely.

Installation is straightforward in most Hackney properties because the shower only needs a cold water connection and a dedicated electrical supply. There is no need to route hot water pipework from a cylinder or upgrade a system boiler. For flats in converted Victorian and Edwardian terraces — which make up a large proportion of housing in Hackney — this is frequently the most practical choice.

The kW rating determines the flow rate. An 8.5kW unit on a 40A circuit using 6mm cable produces a moderate shower adequate for everyday use. Stepping up to 9.5kW improves flow noticeably and is our most frequently fitted rating across Hackney. The 10.8kW high-power option requires a 10mm supply cable and a 45A breaker but delivers the strongest flow an electric shower can produce — comparable to a mixer shower fed from a pressurised cylinder.

All electric shower installation in a bathroom is classified as Part P notifiable work under Building Regulations. This means the installation must be carried out by a registered competent person, or else submitted to Building Control before work begins. Our Part P registered electricians self-certify the work and notify your local Hackney authority on your behalf. You receive an electrical installation certificate and a Building Regs completion notice — essential documents for conveyancing and remortgaging.

RCD protection is a non-negotiable requirement. Every electric shower circuit must be protected by a residual current device (RCD) either as a dedicated RCB on an RCD consumer unit, or as an RCBO on a split-load board. We check the consumer unit configuration before starting and upgrade the protection where necessary. Cable sizing is calculated to load: 6mm twin-and-earth for 8.5kW and 9.5kW units, 10mm twin-and-earth for 10.8kW, run in conduit or clipped direct where accessible.

Thermostatic electric showers add a further layer of comfort and safety by stabilising the outlet temperature when mains pressure fluctuates. In Hackney high-rises and mansion blocks where shared risers cause pressure variation during peak demand, a thermostatic unit eliminates sudden hot or cold surges. We stock and install thermostatic models across the full kW range.
