New electric shower installation or like-for-like replacement across Essex and East London. KLIC ELECTRICAL handles the full electrical connection — dedicated circuit, RCBO protection, and Part P certification as standard.
An electric shower heats water on demand from your mains cold water supply — making it one of the most energy-efficient ways to shower. Unlike mixer showers, an electric shower is independent of your boiler, meaning hot water is always available even if your heating is off. Correct electrical installation is critical — an electric shower requires a dedicated circuit, correctly rated cable, and appropriate overcurrent protection.
KLIC ELECTRICAL installs all major electric shower brands across Essex and East London — from straightforward like-for-like replacements to brand-new installations in new bathrooms. Every connection includes a dedicated RCBO-protected circuit, correct cable sizing, and full Part P certification.
We check your consumer unit has capacity for a dedicated shower circuit and confirm the correct MCB/RCBO rating for your chosen shower kW rating.
A dedicated radial circuit from your consumer unit to the shower location — using correctly sized twin-and-earth cable rated for the shower's power demand.
A dedicated RCBO (combined overcurrent and RCD protection) installed at the consumer unit for the shower circuit — providing maximum safety protection.
Ceiling-mounted 45A pull cord switch installed in the bathroom — providing a safe, local isolation point for the shower unit in compliance with BS 7671.
The shower unit is connected to the dedicated circuit — either by us directly or coordinated with your plumber for the full installation.
Full circuit testing completed and Electrical Installation Certificate issued. Work notified to Building Control under Part P.
An electric shower is one of the highest-load domestic appliances. Incorrect installation creates a serious risk of fire, electric shock, or nuisance tripping.
A 10.8kW shower draws approximately 45 amps. Using undersized cable causes dangerous overheating. We always calculate the correct cable size based on shower rating and cable run length.
All electrical work in bathrooms must comply with BS 7671 bathroom zone requirements. Shower installations fall within Zone 1 — requiring specific equipment ratings and RCD protection.
Electric shower installation is notifiable under Part P of the Building Regulations in England. As NICEIC Approved Contractors, we self-certify all shower electrical work with full legal compliance.

Which kW Rating Should I Choose?
Higher kW = hotter water at lower pressure. 8.5kW suits low-pressure supplies. 9.5kW is the most common residential choice — providing a comfortable shower at standard mains pressure. 10.8kW delivers the hottest water and is recommended for properties with high pressure supplies. We advise on the right rating during the assessment.

Common questions about electric shower installation in Essex and East London.
A like-for-like electric shower replacement (electrical connection only, no plumbing) typically costs £180–£300. A new installation requiring a new dedicated circuit from the consumer unit typically costs £300–£500. We provide fixed written quotes — contact us with your shower make, model, and kW rating for an accurate price.
Yes — an electric shower must have its own dedicated radial circuit from the consumer unit. It cannot share a circuit with other appliances due to its high power demand. The circuit must be protected by a correctly rated RCBO or MCB and 30mA RCD protection.
The right kW rating depends on your mains water pressure. 8.5kW suits low-pressure supplies. 9.5kW is the most popular choice for standard mains pressure properties. 10.8kW delivers the hottest shower and requires good mains pressure. We advise on the best rating during the assessment — choosing too high a rating for your pressure results in a poor shower experience.
It depends on your existing circuit. If your current shower is 7.2kW and you want to upgrade to 10.8kW, the cable size and RCBO rating will need to be upgraded as well. We assess the existing installation during the site visit and advise on what work is required for the upgrade.
We carry out the electrical connection, dedicated circuit, and all associated electrical work. The plumbing connection (water supply to the shower unit) is typically carried out by a plumber. We are happy to coordinate with your plumber or recommend trusted local plumbers if needed.
Yes — electric shower installation is notifiable under Part P of the Building Regulations in England and Wales, as it involves a new circuit in a bathroom.
