Replacement of 9kW Electric Shower with 7.5kW Shower in London

I need to remove a 9kW electric shower and replace it with a 7.5kW unit in my terraced home in London. The property does not require rewiring or socket replacements for this job.

Expert Guidance on Shower Replacement

Replacing an electric shower requires attention to safety and compatibility with the existing electrical setup. In this case, switching from a 9kW to a 7.5kW unit may not necessitate major adjustments, but a professional installation ensures compliance with UK electrical regulations.

Steps for Electric Shower Replacement

1. Safety First

The power supply to the existing shower is turned off at the consumer unit to ensure safe removal. An electrician will verify that the circuit is isolated before starting work.

2. Removal of the Existing Shower

The 9kW shower is carefully disconnected from the water and electrical supply. The wall mounting is inspected for suitability for the new 7.5kW unit.

3. Installing the New Shower

The 7.5kW shower is mounted in place, connected to the existing water supply, and wired into the existing electrical circuit. Any adjustments to the mounting or connections are made to ensure a secure and safe fit.

4. Testing and Certification

Once installed, the shower is tested to confirm it operates correctly and safely. An electrician will issue a Minor Electrical Installation Works Certificate if required.

Cost and Timeline

The cost for removing and replacing an electric shower varies based on labour and any necessary adjustments:

  • Shower Replacement: £100–£250 for labour, excluding the cost of the new shower unit.
  • New Shower Unit: £100–£300, depending on brand and features.

The installation process typically takes 2–3 hours, ensuring minimal disruption to your day.

Considerations for Electric Showers

  • Circuit Compatibility: The existing circuit should be suitable for a 7.5kW unit, requiring a minimum of 32 amps. The existing cable size (usually 6mm² or 10mm²) will also be checked for compatibility.
  • Water Pressure: A 7.5kW shower may require a higher water flow rate than the 9kW unit. An installer will ensure the water supply meets the new shower’s requirements.

Benefits of Professional Installation

Engaging a qualified electrician for the replacement ensures:

  • Compliance with Part P of the Building Regulations.
  • Safe installation with no risk of electrical faults.
  • Peace of mind with testing and certification.

Local Considerations in London

Properties in London, particularly terraced homes, often have older wiring systems. While rewiring isn’t required for this job, a professional electrician will assess the existing setup to ensure it meets current standards.

Preparation for Homeowners

Before the electrician arrives, ensure the bathroom is clear of obstructions around the shower area. Have the new 7.5kW unit ready if you’ve already purchased one, or discuss options with your installer to source a suitable model.
