Why Choose an Electric Shower for Your Cardiff Home?
Electric showers are one of the most popular choices in Cardiff homes — and for good reason. Unlike mixer showers, they connect directly to your cold mains water supply and heat water on demand using a built-in heating element. This means they are completely independent from your boiler and hot water cylinder, so you’ll always have a hot shower available — even if the boiler is off or another family member has used all the hot water.
Key benefits of electric showers
Our Electric Shower Installation Process in Cardiff
Gabe Electrical follow a thorough, step-by-step approach to every electric shower installation in Cardiff — ensuring your safety and complete peace of mind from start to finish.
Initial assessment
Before any work begins, we assess your home’s existing electrical system and check whether your consumer unit — often called a fuse box — has capacity for a new dedicated circuit. As part of this, we also check that the earthing arrangements, main bonding, and RCD protection are suitable, helping to ensure the installation can be carried out safely and in line with current electrical standards.
We also check your mains water pressure to confirm compatibility with the shower unit you have in mind.
Shower unit selection
Not sure which shower to choose? We’re happy to advise on the best unit for your budget, bathroom layout, and household needs — including the right kW rating for your water pressure and electrical setup. Higher kW models (9.5 kW or 10.5 kW) deliver stronger flow but require heavier cabling and a correctly rated circuit breaker.
Dedicated circuit installation
Every electric shower requires its own dedicated circuit running from the consumer unit to the shower position, using the correct cable size and an RCD (Residual Current Device) for protection. We install all circuits to BS 7671 wiring standards, ensuring your home is safe and compliant.
Installation and testing
Once the circuit is in place, we fit and connect the shower unit — making sure everything is watertight and correctly isolated. After installation, we carry out rigorous testing and provide you with a BS 7671 electrical installation certificate to confirm the work meets all safety and building standards.
Part P Compliance — Why It Matters for Cardiff Homeowners
All electrical work carried out in bathrooms in the UK — including electric shower installations — falls under Part P of the Building Regulations. This legislation requires the work to be completed by a qualified, competent person to ensure it is safe and meets current standards.
As Part P-registered electricians, Gabe Electrical can self-certify our own work — meaning there’s no need for a separate building control inspection. Once the installation is complete, we issue a compliance certificate, which is important for your home insurance and if you ever come to sell your property.
Please be cautious about unlicensed tradespeople offering cheap installations. Unsafe or uncertified electrical work in a bathroom carries serious risks, including electrical fire, electrocution, and invalidated home insurance.
Electric Shower Installation Cost in Cardiff — What to Expect

Frequently Asked Questions About Electric Shower Installation in Cardiff
Do I need a Part P electrician to install an electric shower in Cardiff?
Yes, in almost all cases. Any new electrical work in a bathroom — including installing a new circuit for an electric shower — must comply with Part P of the Building Regulations. You either need a registered electrician who can self-certify the work, or you need to notify your local building control. Gabe Electrical are Part P-registered, so we handle the certification for you.
How long does an electric shower installation take?
A like-for-like replacement typically takes around two to three hours. A first-time installation requiring a new dedicated circuit can take three to five hours, depending on the property layout and the distance from the consumer unit to the bathroom.
Which electric shower brands do you install?
We install all leading brands, including Mira, Triton, Aqualisa, and Bristan. If you have already purchased a unit, we’re happy to fit it. If not, we can recommend a model suited to your water pressure, budget, and household needs.
What kW rating do I need?
Electric showers are available from around 7.5 kW up to 10.5 kW. Higher kW ratings produce better flow and hotter water, but they require heavier-duty cabling and your consumer unit must have the capacity to support them. Many Cardiff homes are well-suited to a 9.5 kW unit — we’ll advise you on the right choice for your home during the initial assessment.
Can I install an electric shower myself?
A simple like-for-like swap of an identical unit with no new electrical work may technically be possible without a certified electrician, but in the vast majority of cases new cabling or circuit changes are required — and this must be done by a qualified, Part P-registered professional. Given that electric showers combine high-voltage electricity with water, we strongly advise against DIY installation. The risks include electrical fire, electrocution, and invalidated insurance.
Will you provide documentation after a repair or installation?
Yes. Some electrical work in a bathroom is notifiable to local building control (PartP). Where certification is required — for example, if a new circuit or significant repair is carried out — we provide the relevant NICEIC-backed documentation. All our work complies with BS 7671 (the IET Wiring Regulations).
