Why electric showers suit London properties
Independent of your boiler — ideal for London flats
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 Ealing 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 Ealing — 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 Ealing. 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 Ealing 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 Ealing 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.

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.
New circuit installation
Full installation including new dedicated circuit from consumer unit, correctly sized cable run (6mm or 10mm), RCD protection, and Part P Building Regs notification to your local authority.
Thermostatic electric shower
Thermostatic models maintain a constant outlet temperature regardless of mains pressure fluctuations — ideal for London flats where pressure can vary. Prevents scalding and cold surges.

Electric shower installation Ealing: frequently asked
Does an electric shower installation need Building Regs in Ealing?
Yes. Electric shower installation is Part P notifiable work under Building Regulations because it involves a new or replacement circuit in a bathroom. Our Part P registered electricians handle the notification to Ealing Building Control automatically — you receive a completion certificate as proof of compliance.
What kW electric shower do I need in Ealing?
The right kW rating depends on your mains water pressure. In most Ealing properties, a 9.5kW unit is the best balance of flow rate and cable cost. Properties with strong mains pressure benefit from 10.8kW for the best flow. 8.5kW suits older flats where existing wiring limits the circuit. We assess your setup before recommending a unit.
Can I fit an electric shower in a Ealing flat?
Yes — electric showers are particularly well suited to London flats because they connect directly to the cold mains supply and heat water on demand. They work completely independently of the boiler and require no storage tank. The main consideration is routing the supply cable back to the consumer unit, which we manage within the flat without breaching floors or communal areas where possible.
How long does electric shower installation take in Ealing?
A like-for-like replacement in Ealing typically takes 2 to 3 hours. A new installation with a fresh cable run from the consumer unit takes 4 to 6 hours depending on the distance and routing required. We aim to complete most jobs in a single visit so you have a working shower the same day.
