Electric shower fitting and replacement
Electric shower installation and replacement
Replacing a shower or fitting one for the first time? Start with a unit that suits the water supply, electrical circuit and bathroom.
Upkeepone reviews electric shower installation enquiries across London, Essex and Kent. Tell us what is fitted now, the replacement you have in mind and your postcode. We will clarify the work and suitable attendance before a booking is confirmed.
Qualified engineers, with NAPIT or NICEIC registration where applicable. A higher power rating needs an installation assessment; it is not automatically a suitable upgrade.
Describe your bathroom setup
Request an installation callback
Include the postcode, existing shower make and model, known kW rating and any proposed replacement. Say whether this is a swap or a new installation, and mention access or bathroom work.
Use information already safely available. Do not remove the shower cover or inspect wiring to find details. Your enquiry is reviewed before attendance is agreed.
Check which shower you have
Electric showers heat the water at the unit
An electric shower takes a cold water supply and heats it as it passes through the shower. It does not rely on stored hot water or the boiler to heat that water. This is different from a mixer shower, which combines the home’s hot and cold supplies, and from a power shower, which uses a pump with an appropriate hot and cold water system.
The casing alone is not enough to identify a shower. If you are unsure, send its name or a photograph taken without opening or moving the unit. Mira’s guide to shower types can help you describe what is there.
Planning a different type of shower?
For mixer showers, enclosures, trays or a wider bathroom project, start with our shower installation service. Converting a mixer or power shower to an electric shower needs a fresh assessment of both water and electrical provision.
A replacement that fits the installation
What needs checking before an electric shower is replaced?
A new unit may look similar but have different connections or requirements. Share the old and proposed models before arranging the fitting, particularly if you want to change the brand, position or power rating.
Power rating and circuit
The kW rating is one part of selecting a replacement. Its electrical demand must suit the installation; matching the old rating alone does not establish that the existing circuit is safe or suitable.
Water and cable entry
The positions where water and wiring enter the unit affect whether it can fit without alterations. Pipework or cable changes should be identified as part of the assessment, rather than discovered after a replacement is purchased.
Wall and fittings
Check the proposed unit’s dimensions against the existing position. Old fixing holes, damaged tiles or gaps around a smaller casing may need making good. Agree the rail, hose and handset arrangements with the installer too.
Triton’s replacement guidance highlights these model and supply checks. An adaptable or replacement-friendly product still needs checking against your bathroom.
Water and electricity need separate checks
Electrical protection and the water supply
An electric shower needs an appropriate dedicated circuit and suitable protection. The electrician should assess the existing cable, protective devices, earthing, isolation and capacity for the chosen model. Cable size cannot be selected from the shower’s kW rating alone; the installation conditions also matter.
RCD protection helps reduce the risk of electric shock. Ask the installer to confirm the protection and bathroom electrical requirements for your work. Electrical Safety First explains bathroom electrical safety.
The water supply must meet the manufacturer’s requirements for running pressure and flow. Most electric showers use the cold mains; a pumped model intended for a different supply needs its own specification. An ordinary mains-fed unit is not interchangeable with every pumped shower.
Considering a more powerful shower?
A move to a higher kW rating may involve electrical upgrades as well as a water-supply check. Describe the proposed change before ordering. Any extra circuit, consumer-unit or plumbing work needs its scope and price agreed first.
If the old shower may be unsafe
Stop using it if it trips repeatedly, smells of burning, has damaged electrical controls or leaks from the unit. Keep clear of wet electrical equipment and arrange an assessment. Do not keep resetting the protection or open the casing to investigate.
Know what the fitting price covers
How much does electric shower installation cost?
The scope makes the difference. Replacing a compatible unit on suitable existing connections involves different work from fitting a shower where no circuit or water connection exists. Moving the unit, increasing its rating or repairing the wall can also change the quotation.
Send the models and postcode, whether the shower has been bought or delivered, and any bathroom plans. Mention tenants or residents who need access arrangements, parking restrictions and a preferred date. We will review those details before confirming the appropriate quotation route.
Supply and connection
Confirm who supplies the shower and fittings, whether both water and electrical connections are included, and what checks and commissioning form part of the work. Ask whether the price assumes existing provision is suitable.
Extra work and charges
New wiring, changed pipework, isolation valves, wall repairs, tiling and disposal should be itemised if required. Check the total price, VAT and any travel charges. Additional work should be explained and agreed before it proceeds.
No fixed fitting price or completion time is promised on this page. A confirmed scope gives you a clearer basis for comparing quotations and planning use of the bathroom.
Complete the work and keep the records
Testing, commissioning and electrical certification
The installer should check the agreed electrical and water work, commission the shower following its instructions, check for leaks and demonstrate normal operation. Keep the supplied hose and showerhead arrangements within the manufacturer’s specification; do not assume an alternative handset is suitable.
Ask how to use the controls and care for the shower, and keep the appliance instructions, relevant test records and completion documents. Warranty registration and any installation workmanship terms should be clarified at handover.
Which electrical certificate applies?
A new circuit needs an Electrical Installation Certificate. Suitable additions or alterations without a new circuit may use a Minor Electrical Installation Works Certificate or an EIC. See NICEIC’s explanation of electrical certificates.
In England, new circuits and additions or alterations in the defined special locations around a bath or shower are notifiable. A straightforward equipment replacement is not automatically notifiable. The installer needs to confirm the actual scope. Notification is separate from electrical certification. Approved Document P explains the rules for dwellings in England; requirements differ elsewhere in the UK.
Upkeepone’s engineers are qualified, with NAPIT or NICEIC registration where applicable. The electrical and plumbing support must match the work required; ask for the relevant registration details when arrangements are confirmed.

Common fitting questions
Electric shower installation FAQs
Can you replace my existing electric shower?
Send the current make, model and power rating if you already know them, together with your postcode and the proposed replacement. A suitable replacement needs compatible water and cable entry points, room to fit and an appropriate electrical supply. Even a similar-looking unit needs checking. We will review the details and confirm the assessment and quotation route.
Can I upgrade from an 8.5kW shower to a 10.5kW shower?
A higher-rated shower can place a greater demand on the electrical installation. Do not order it on the assumption that the existing circuit will support it. The electrician needs to assess the cable, protection, supply capacity and installation conditions, while the water supply must meet the new model’s requirements. Extra electrical or plumbing work may be needed and should be quoted separately.
Does an electric shower work with a combi boiler?
An electric shower heats its own cold water supply rather than using hot water from the combi boiler. It therefore needs a suitable cold supply and its own electrical provision. A mixer shower uses the home’s hot and cold supplies instead. Tell us which type you have; converting between them involves more than changing the wall-mounted unit.
Will a new electric shower fix weak water flow?
Not necessarily. Performance depends on the model and the water pressure and flow available while it is running. A replacement cannot be assumed to correct a supply problem. Describe when the flow is weak and whether other outlets are affected, so the installer can assess the cause and suitable options before a new shower is selected.
Do I need an electrician or a plumber for installation?
The job needs competence for both its electrical and water connections. Some installations can be handled by an appropriately qualified installer; others need coordinated electrical and plumbing work. Tell us whether you need a replacement unit, a new circuit, pipework changes or bathroom alterations. We will clarify the required support and responsibilities before attendance is agreed.
Does replacing an electric shower need Building Regulations notification?
In England, a new circuit is notifiable, as are additions or alterations to existing circuits within the defined special locations around a bath or shower. A straightforward equipment replacement is not automatically notifiable. The installer should confirm what applies to the actual work and provide appropriate electrical certification. Building Regulations notification is a separate record; other UK jurisdictions have different rules.
Are tiling, removal and the new shower included in the price?
Those items need to be agreed in the quotation. Confirm who supplies the shower, whether the price assumes the existing connections are suitable, and what testing and records are included. Ask separately about wall repairs, tiling, pipework, new wiring, removal and disposal. The final quotation should make VAT, travel and any other charges clear.
Tell us which shower you need fitted
Start with the postcode, current model and proposed replacement, or explain that this is a first installation. Include any water, wiring or wall changes you already know about so we can clarify the next step.
