Electric Shower Installation
An electric shower heats water as it flows, so you get hot water whenever you need it, regardless of your boiler or tank. It's a popular choice for ensuites, family bathrooms with a combi boiler that struggles, and homes where the hot water always seems to run out at the wrong moment.

Our electric showers treatment process
Step 1 Contact
Tell us the make, model and power rating of the shower, and send a photo of your current shower, isolator and consumer unit if you have one.
Step 2 The Quote
We check whether the existing circuit is suitable or needs upgrading, then give you a fixed price for the circuit work, isolator and connection.
Step 3 The Works
Our electrician installs or tests the dedicated circuit, fits the isolator, connects the shower and follows bathroom zone requirements throughout.
Step 4 After care
The circuit is tested under BS 7671. You receive an Electrical Installation or Minor Works Certificate, and building control is notified for new circuits.

FAQs
Pricing & Payment
What affects the cost of an electric shower installation?
Whether a new circuit is needed, the distance from the consumer unit to the bathroom, the shower's power rating and whether your consumer unit has space. Replacing a like-for-like shower on a suitable circuit is simpler. We'll give you a fixed price first.
Booking & Response Times
Can you fit my new electric shower before the bathroom is tiled?
Yes, and it's the best way to do it. We run the cable and fit the isolator at first fix, then return to connect the shower once your fitter has finished tiling and the unit is mounted. Tell us your fitter's schedule and we'll fit around it.
The Work Itself
Do you fit the plumbing side of an electric shower?
Our electricians handle the electrical installation, including the circuit, isolator and connection. Many customers have a plumber or bathroom fitter connect the water supply, and we're happy to coordinate with them on timings. That way the shower is connected, tested and ready to use in one coordinated job.
Why does my electric shower keep cutting out?
Common causes include low water pressure, a failing heating element, an overheated isolator or an undersized circuit. If the isolator switch is discoloured or warm, stop using the shower and have the circuit checked. A thermal cut-out inside the shower can also trip if the unit is overheating, which is a sign it needs attention.
Can I replace my electric shower with a more powerful one?
Possibly, but the circuit must be able to handle it. A 10.5kW shower draws more current than an older 8.5kW model, so the cable size, circuit breaker and isolator all need checking. Sometimes the circuit needs upgrading. We'll test first and tell you before you buy.
Regulations & Compliance
Is installing an electric shower notifiable?
A new circuit for an electric shower is notifiable under Part P. We notify building control through our NICEIC registration. Replacing a shower on an existing, suitable circuit isn't notifiable but is still tested and certified. Either way, you'll receive test results for your records.
What are bathroom zones?
Bathrooms are divided into zones based on how close each area is to the bath or shower. Every electrical fitting must be rated for its zone, and switches are kept outside the room or on a ceiling pull cord. Following them is a key part of keeping a bathroom safe.
Does an electric shower need RCD protection?
Yes. BS 7671 requires circuits supplying equipment in bathrooms, including electric showers, to be protected by an RCD. If your current circuit isn't RCD-protected, we'll explain the options to bring it up to standard. This may mean adding an RCBO to your board or upgrading the board itself.
Certificates & Paperwork
What certificate will I get for my electric shower circuit?
A new shower circuit is recorded on an Electrical Installation Certificate, with building control notified. Work on an existing circuit, such as a like-for-like replacement, is recorded on a Minor Electrical Installation Works Certificate. Keep it with your other home documents, as buyers' solicitors often ask for it.
Guarantees & Aftercare
Who do I contact if the shower unit itself develops a fault?
If the fault is with the shower unit, it's covered by the manufacturer's warranty, so contact them first. If it relates to the circuit, isolator or connections we installed, call us and we'll come back to check it. If you're unsure which it is, call us and we'll help you work it out.

Why the circuit matters
An electric shower is one of the most powerful appliances in a home. A typical model draws between 8.5kW and 10.5kW, more than a kettle, an oven and a washing machine put together. It needs its own dedicated circuit, run directly from the consumer unit, with cable sized for the load and the length of the run.
Problems we see when showers have been fitted without the right circuit include:
- A shower that never gets properly hot or keeps cutting out
- A pull-cord switch or isolator that's discoloured or smells of burning
- Cable that's warm to the touch where it runs through the loft
- An RCD or circuit breaker that trips when the shower is on
All of these point to a circuit that's undersized, poorly connected or overloaded. They should be checked before the shower is used again.
Replacing an existing shower
If you're replacing an old electric shower with a new one of the same or lower power rating, the existing circuit may be fine. We'll still test it, check the cable size, connections and isolator, and confirm it suits the new unit before we fit it.
Upgrading to a more powerful shower is a different matter. A 10.5kW shower on a circuit designed for an older 7kW model can overload the cable. In that case we'll recommend upgrading the circuit, and explain why.
New electric shower installations
For a brand new installation, we'll run a dedicated circuit from your consumer unit, fit a ceiling pull-cord isolator or a wall-mounted switch outside the bathroom, and connect the shower. The circuit is protected by an RCD, which is a requirement for bathroom circuits under BS 7671.
If your consumer unit has no spare space or no RCD protection, we may need to upgrade it first. See consumer unit replacement for what's involved.
Bathroom zones and regulations
Bathrooms are treated as special locations in the wiring regulations because of the extra risk where water and electricity meet. Each part of the room is divided into zones based on distance from the bath or shower, and every fitting must be suitable for the zone it's in.
Installing a new circuit in a bathroom is notifiable under Part P. We notify building control for you, and you receive an Electrical Installation Certificate. Work on an existing circuit is recorded on a Minor Electrical Installation Works Certificate.
Working with your bathroom fitter
If your bathroom is being refitted, the best time to run a new shower circuit is before the tiling starts. We're happy to coordinate with your fitter or plumber so the cable is in place at first fix and the shower is connected at the end. We can wire your bathroom lighting and extractor fan at the same time.
