Electric Shower Installation Cost UK (Supply & Fit)

Electric Shower Installation Cost UK: Supply and Fit Prices for 2026

The cost of replacing an electric shower in the UK depends on whether the existing cable, protective device, isolator and cold-water connection can be reused. Based on InstantCost’s 2026 labour figures, a compatible like-for-like replacement can require approximately £80 to £300 in electrician labour, before the price of the shower, minor parts and any applicable VAT.

A brand-new electric shower installation is more expensive because it normally needs a dedicated circuit and may require new plumbing. A full day of electrical work produces an InstantCost-based labour allowance of approximately £300 to £600. The shower unit, cable, protective devices, plumbing, certification and wall repairs must then be added.

Quick answer:

• Compatible like-for-like replacement labour: approximately £80 to £300

• New dedicated shower circuit labour allowance: approximately £300 to £600 for one working day

• Electrician rate: £40 to £75 per hour

• Plumber rate, if separate plumbing is required: £40 to £80 per hour

• Possible consumer unit replacement: £550 to £950

• Shower unit, cable, fittings, certification and finishing work: quoted separately

Figures were calculated from InstantCost electrician, plumbing and bathroom data checked on 27 October 2026. InstantCost does not currently publish one standalone electric shower unit price, so the supply cost must be confirmed for the model selected. All figures are estimates rather than fixed quotations.

Electric shower installation cost breakdown

How these estimates were calculated: The replacement labour range uses two to four hours at InstantCost’s £40 to £75 electrician rate. The new-circuit allowance uses 7.5 to 8 hours at the same rate. These are transparent planning calculations, not a claim that every electric shower takes the same time to install.

What is included in an electric shower supply-and-fit quote?

An electric shower and fitting quotation should identify both the product being supplied and the installation work. A description such as “supply and fit shower” is not detailed enough for a safe comparison.

A complete quotation may include:

• The make, model and power rating of the electric shower

• Removal and disposal of the existing unit

• Inspection of the existing dedicated circuit

• Testing of the cable, protective device and RCD protection

• Connection to the existing cold-water supply

• A new or replacement shower isolator where needed

• Electrical and plumbing fittings

• Commissioning and temperature checks

• Electrical inspection, testing and certification

• Any required Building Regulations notification

• VAT, where applicable

It may exclude tile repairs, wall panels, plastering, decoration, a new shower screen, tray repairs and upgrades to the consumer unit. These exclusions should be clear before work starts.

Cost to replace an electric shower in the UK

The cost to replace an electric shower in the UK is lowest when the new unit is compatible with the existing installation. Compatibility involves more than choosing a shower with similar dimensions.

The installer must assess:

• The shower’s kilowatt rating

• The cable size, installation method and cable route

• The circuit breaker or protective device

• RCD protection

• The main electrical supply and consumer unit

• The shower isolator and its connections

• The cold-water pressure and pipe connection

• The manufacturer’s installation requirements

If all these parts are suitable, the work may take a few hours. Using the InstantCost electrician rate, that gives a labour estimate of approximately £80 to £300.

Compatible replacement calculation

2 hours × £40 = £80

4 hours × £75 = £300

Add the chosen shower unit, minor fittings, disposal and VAT where applicable.

The lower end is more realistic when pipe and cable entries align with the new unit and the existing circuit passes inspection. The upper end becomes more likely when access is awkward, connections need alteration or faults are found during testing.

Does like for like mean the same brand?

Not necessarily. A replacement from the same manufacturer can sometimes align more easily with existing pipe and cable entries, but the installer must still check the complete installation.

Two showers with the same outer dimensions may have different internal connection points. Similarly, two units marked with the same power rating may have different manufacturer requirements.

A proper like-for-like replacement means the new shower is suitable for the existing electrical supply, water connection and installation conditions. It does not simply mean that it fits over the marks left by the old unit.

Can you replace an 8.5kW shower with a 9.5kW or 10.5kW model?

Only after the existing circuit has been assessed. A higher-rated shower draws more current and may need a different cable or protective device. The cable’s suitability also depends on its route, length, insulation, grouping and ambient conditions.

Do not assume a cable is suitable based only on its visible width or an old label at the consumer unit. The installer should verify the circuit and follow the new shower manufacturer’s requirements.

If the existing circuit cannot support the higher-powered unit, your choices are to select a compatible shower or pay for the required electrical upgrades.

How much does it cost to wire an electric shower?

The cost to wire an electric shower cannot be priced accurately from the power rating alone. A new electric shower usually requires a dedicated circuit running from the consumer unit to the bathroom.

For budgeting, one full day of electrician labour is approximately £300 to £600 based on InstantCost’s current hourly range. This does not include the shower, cable, isolator, protective device, plumbing, certification or repairs to walls and ceilings.

New circuit labour calculation

7.5 hours × £40 = £300

8 hours × £75 = £600

The actual wiring quote depends on:

• The distance between the consumer unit and bathroom

• Whether the cable can pass through a loft, cupboard or floor void

• Whether floors or ceilings need opening

• The shower’s power rating

• The cable size selected by the electrician

• The condition and capacity of the consumer unit

• The required protective device and RCD arrangement

• The position of the shower isolator

• Fire stopping and repairs after the cable is installed

• Testing, certification and notification requirements

A short, accessible route through an empty loft is normally cheaper than routing a cable across several finished rooms. Ask the electrician to state whether lifting floors, cutting access holes and making good are included.

Calculate My Electrical Cost

When could the consumer unit increase the price?

An older consumer unit does not automatically mean it must be replaced. The electrician should assess the existing equipment, protective devices, available capacity, earthing and bonding before recommending an upgrade.

If a consumer unit replacement is genuinely required, InstantCost’s 2026 guide places the typical price at £550 to £950. The quotation should explain why the work is needed and whether the price includes testing, protective devices, certification and notification.

Be cautious if a contractor recommends an expensive consumer unit replacement without inspecting or testing the existing installation.

How much does the plumbing work cost?

An electric shower normally heats cold mains water inside the unit. It does not require a hot-water connection from the boiler or cylinder.

If the existing cold-water pipe is correctly positioned and in good condition, the installer may complete the connection as part of the replacement. When a new pipe is required, InstantCost’s standard plumbing labour rate is £40 to £80 per hour.

Plumbing costs can rise when:

• The shower is being installed in a new position

• No suitable cold-water feed is nearby

• The existing stop valve or pipework is damaged

• Tiles or wall panels restrict access

• The incoming water pressure or flow is unsuitable

• Leaks or previous poor-quality connections are discovered

Do not automatically add a separate plumber’s visit to every quotation. Some electric shower installers are able to complete the required cold-water connection. Ask who will handle each part of the job and who is responsible for testing it.

What can increase the electric shower fitting cost?

Changing the power rating

A more powerful shower may need changes to the cable, circuit protection or consumer unit. Buying the shower before the circuit has been checked can leave you with a product that cannot be installed economically.

Moving the shower

A new position can require longer pipework, a new cable route, tile drilling, wall repairs and changes to the riser rail or screen. Keeping the current position is normally the least expensive option.

Difficult cable routing

Finished ceilings, tiled walls, concrete floors and inaccessible voids increase labour. Ask where the cable will run and whether any visible trunking will be required.

Damaged shower isolator

Heat damage, loose connections or discolouration at a pull-cord or wall isolator requires investigation. Replacing only the shower will not correct a defective isolator or damaged circuit connection.

Water damage behind the old shower

A leaking unit can damage wall boards, fixings and surrounding finishes. The new shower should not be mounted over an unsound or damp background.

Out-of-hours installation

An urgent evening or weekend visit usually costs more than a planned weekday appointment. If the shower has failed but can be safely isolated, arranging a scheduled replacement may reduce the cost.

Should you buy the electric shower yourself?

Buying the shower yourself can give you control over its appearance and features, but confirm compatibility before ordering it. The lowest online price is not useful if the unit needs an expensive circuit upgrade or does not align with the existing connections.

Ask the installer to confirm:

• The acceptable power rating

• Whether a thermostatic model is appropriate

• Where the water and electrical entries need to be

• Whether the existing riser rail can remain

• Who handles a faulty product warranty

• Whether labour for removing a defective new product is covered

When the installer supplies the shower, check the exact model and warranty rather than accepting an unidentified allowance. When you supply it, ask whether the installer warrants only the workmanship.

Electric shower installation near me: how to compare installers

A search for “electric shower installation near me” often produces electricians, plumbers, bathroom fitters and large national maintenance companies. The right choice is a contractor who can take responsibility for both the high-powered electrical connection and the necessary plumbing.

Send every prospective electric shower installer the same information:

• Your postcode

• The make, model and power rating of the existing shower

• The proposed replacement model, if already chosen

• Photographs of the shower, pipe entry and cable entry

• A photograph of the consumer unit and circuit labels

• The approximate distance from the consumer unit to the bathroom

• Whether the shower is faulty, leaking or showing heat damage

• Whether you want the installer to supply the new unit

Photographs can help an installer prepare, but they cannot prove the cable size, circuit condition or suitability of the protective devices. Treat any remote estimate as provisional until the installation has been inspected.

Questions to ask before accepting a quote

• Is this a fixed price or an estimate?

• Which shower model and power rating are included?

• Has the existing circuit been assessed?

• Does the quote include the cold-water connection?

• Is a new isolator included if required?

• Are cable, protective devices and small fittings included?

• Does the price include removing the old shower?

• Who will repair damaged tiles or wall finishes?

• Are testing and certification included?

• Will the installer handle any required notification?

• Is VAT included?

• What warranty covers the shower and installation?

• How will additional work be approved?

Common electric shower quotation mistakes

• Comparing a labour-only price with a supply-and-fit quote

• Assuming the existing cable can support a higher-powered shower

• Buying a shower before an electrician checks compatibility

• Not asking whether the call-out includes the first hour

• Forgetting about plumbing changes and water isolation

• Assuming tile and plaster repairs are included

• Accepting a consumer unit upgrade without a clear technical reason

• Not checking whether testing and certification are included

• Choosing an installer based only on the lowest headline price

Can you fit an electric shower yourself?

Fitting an electric shower is not an appropriate DIY project. The unit combines water with a high-powered electrical supply in a bathroom. The work requires correct circuit design, safe isolation, cable selection, protective devices, water connections and electrical testing.

Even a physical replacement that appears straightforward can reveal overheated terminals, an unsuitable cable, damaged isolation equipment or missing protection. These conditions cannot be judged from the shower casing alone.

Electric shower installation safety

Do not use a shower that smells of burning, makes crackling sounds, trips its protective device repeatedly or has signs of scorching, melting or water leakage around electrical parts. Switch it off using the appropriate isolation method if this can be done safely, and arrange professional inspection.

Electric showers should have a suitable dedicated circuit, protective devices and safe means of isolation. Bathroom electrical work must follow the rules applicable in the relevant UK nation. A new circuit is notifiable work in England, while bathroom work within defined zones can also have notification requirements.

The NICEIC electric shower installation safety guide explains why the cable, protective devices, bathroom location and water connection must all be assessed by a registered professional.

Requirements and notification procedures differ across England, Wales, Scotland and Northern Ireland. Ask the installer which rules apply to the property and what certificate or compliance document will be supplied.

How long does fitting an electric shower take?

A compatible replacement may take a few hours when the existing circuit, isolator, pipework and shower position are suitable. Altering connections or correcting defects adds time.

A completely new installation may take a full working day or longer. The programme can extend when a long cable route is required, floors must be lifted, pipework is being added or another trade must repair tiles and wall finishes.

Frequently asked questions

How much does electric shower installation cost in the UK?

Based on InstantCost’s 2026 labour rates, a compatible replacement may require approximately £80 to £300 in electrician labour. Add the shower unit, fittings and VAT where applicable. A new circuit may require £300 to £600 of electrical labour before materials, plumbing and finishing work.

What is the cost to replace an electric shower in the UK?

A straightforward replacement can involve £80 to £300 of electrical labour when the existing dedicated circuit and water connection are suitable. The final supply-and-fit price also includes the chosen shower, minor parts, disposal and any repairs discovered during inspection.

How much does it cost to wire an electric shower?

A new circuit may involve approximately £300 to £600 for one full day of electrician labour. Cable, protective devices, isolator, certification and wall repairs are additional. The precise cost depends heavily on the cable route and the existing consumer unit.

Can a plumber install an electric shower?

The installer must be competent to complete and test the electrical work as well as make the water connection. Some registered electricians can handle both parts. Others coordinate with a plumber. Confirm responsibility for the complete installation before accepting the quote.

Can an electrician install the plumbing connection?

Some electricians are competent and insured to make the required cold-water connection, while others provide only the electrical work. Ask whether the quotation includes plumbing and who will deal with leaks, valves or changes to the pipe route.

Do I need a new circuit for a replacement shower?

Not always. A suitable existing dedicated circuit may be reused after inspection and testing. A new circuit or other upgrade may be needed if the shower rating changes, the cable is unsuitable, protection is inadequate or damage is found.

Can I replace an 8.5kW shower with a 10.5kW shower?

Only if an electrician confirms that the cable, circuit protection, isolation equipment, consumer unit and main supply are suitable. A higher kilowatt rating normally draws more current. Never upgrade the shower based only on the existing unit’s dimensions.

Does an electric shower installation include the shower unit?

Only when the quote specifically says supply and fit. Labour-only quotations expect you to purchase the shower. Check the exact model, power rating, fittings, warranty, disposal, certification and VAT before comparing prices.

Does the electric shower fitting cost include tiles and decoration?

Usually not. Electrical and plumbing installation may leave access holes, unused fixing points or exposed areas where the new shower is smaller. Ask whether tile replacement, wall panels, filling, sealing and decoration are included or require another contractor.

Is a more powerful electric shower always better?

A higher-powered shower can heat a greater water flow, particularly when incoming water is cold. However, it uses more electrical power and may require circuit upgrades. Choose the rating only after the electrical installation and available water supply have been assessed.
