Electric11 completed a Mira electric shower installation in Norwich, replacing an existing unit with a Mira Advance 8.7kW thermostatic electric shower. The work included removing the older shower, connecting the replacement to the dedicated circuit, completing electrical testing and issuing certification.
The new unit provides the property with a fully operational thermostatic shower while retaining the existing electrical supply arrangement. Recorded test results confirmed that the circuit and protective devices were satisfactory at the time of completion.
This project required a direct replacement for an existing electric shower. Electric showers combine water and a high-powered electrical supply within a bathroom environment, so the circuit, residual-current protection and final connections all needed to be checked carefully.
Electric11 installed the new 8.7kW unit and tested the affected circuit before returning the shower to service.

The installation was designed as a complete home-energy system rather than a standalone solar array. Electricity generated by the panels can be used within the property, stored in the FOX batteries, or exported when generation exceeds household demand and the batteries have sufficient charge.
Battery storage allows more solar electricity to be retained for use later in the day. This can reduce the amount of electricity imported from the grid during periods when solar output is lower.
The property required the existing electric shower to be removed and replaced with a new thermostatic model. The confirmed scope included:
The first stage involved safely isolating the shower circuit and removing the older unit from the tiled bathroom wall. The electrical supply and water connection had to remain controlled throughout the work because both services terminate inside the shower casing.
After removing the cover and disconnecting the old shower, our electrician inspected the available connection points and prepared the area for the replacement unit. This allowed the new installation to use the established shower position without unnecessary changes to the surrounding bathroom.
Electric11 fitted a Mira Advance 8.7kW thermostatic electric shower in place of the previous unit. The shower was mounted securely and connected to the existing water and electrical supplies.
The thermostatic design regulates the selected shower temperature during use. Correct installation remains essential because the unit draws a substantial electrical load while operating in a wet environment.
The completed electric shower installation in Norwich provided a practical replacement while retaining the property’s dedicated shower circuit.
The shower connects to DB1, Circuit 2, which is identified specifically for the shower. The recorded installation method was Reference Method A.
The circuit documentation lists a 32A Type B protective device and 30mA residual-current protection. These devices form part of the circuit’s safety arrangement and were included in the post-installation checks.
Inspecting the circuit alongside the appliance replacement allowed Electric11 to confirm the condition of the affected electrical work rather than treating the project as a simple equipment swap.
Electric11 completed electrical testing after installing the new shower. The recorded results were:
The earth fault loop impedance measurement checks the fault path associated with the circuit. The insulation resistance result records the condition of the tested cable insulation, while the RCD test measures how quickly the protective device disconnects the supply under test conditions.
Together, these results provided documented evidence of the circuit condition at completion.
A Minor Electrical Installation Works certificate was issued for the completed shower replacement. The certificate records the work carried out, the circuit details, the protective devices and the electrical test results.
The documentation confirms that the completed work complied with the applicable requirements of BS 7671. It also gives the property owner a formal record of the installation and testing.
The property received a new Mira Advance 8.7kW thermostatic electric shower connected to the existing dedicated circuit. The replacement restored the shower with a modern unit while avoiding unnecessary alterations to the surrounding bathroom.
Electrical testing recorded satisfactory results, including an earth fault loop impedance of 0.07Ω, insulation resistance of 999MΩ and an RCD disconnection time of 28.5ms.
The issued Minor Electrical Installation Works certificate provides a complete record of the replacement and confirms compliance with BS 7671.
Electric11 provides electric shower replacements and other domestic electrical installations throughout Norwich and the surrounding Norfolk area. Our electricians can assess the existing unit, confirm the circuit requirements and complete the necessary testing and certification.

Moreover, through our extensive network, we have forged strong connections with quality tradesmen representing various disciplines in our area.
Replacing an electric shower requires more than attaching a new unit to the wall. Electric11 reviews the appliance rating, dedicated circuit, protective devices, electrical connections and test results before returning the shower to service.
Existing Shower and Circuit Assessment
Our electrician checks the current shower, mounting position, water connection and electrical circuit. We confirm the replacement unit’s rating and review the circuit protection before starting the installation.
Clear, Detailed Quote
We provide a clear quote covering removal of the existing shower, installation of the replacement, electrical connections, testing and certification. Any additional remedial work identified during the assessment is explained before proceeding.
Safe Shower Replacement
We isolate the electrical and water supplies, remove the old unit and install the replacement in the agreed position. The connections are completed carefully, and the shower casing, hose and controls are checked before commissioning.
Testing and Certification
After installation, we test the affected circuit and residual-current protection against the applicable requirements of BS 7671. We then commission the shower and issue the relevant electrical certificate.
