Electrical Services in Cardiff

Cardiff is one of the most diverse and fast-moving cities in the UK — a capital city whose housing stock spans everything from grand Victorian villas in leafy northern suburbs and tightly packed Edwardian terraces in the inner city through to modern apartment developments in the Bay and new-build estates on the city’s expanding edges. That variety of property type, age, and use means the demand for professional electrical work across Cardiff is as broad and varied as the city itself.

Electrical Services We Offer in Cardiff

⚡ Extractor Fans / Ventilation

Cardiff’s varied housing stock presents ventilation challenges right across the city. Victorian and Edwardian terraces in areas like Cathays, Adamsdown, and Caerau were built without any extraction provision, while newer apartments in the city centre often have extraction systems that have never been serviced or replaced. Without adequate ventilation in kitchens and bathrooms, moisture builds up — leading to condensation, persistent damp, and mould that becomes harder and more expensive to address with every passing season. A properly installed extractor fan removes moisture at source and stops the problem before it starts. Our team installs ventilation solutions across all Cardiff property types to a clean, lasting standard. Find out about our Extractor Fans / Ventilation service.

⚡ Fuseboard / Fuse Box Upgrades

A consumer unit upgrade is one of the most impactful electrical improvements available to Cardiff homeowners — and across a city with such a large proportion of older housing, the need is widespread. Many of Cardiff’s Victorian and Edwardian terraced properties still carry fuse boards that predate modern RCD and RCBO protection, leaving households without the level of safety response that today’s electrical standards require. In newer properties, an original consumer unit may simply have been outgrown by the demands placed on it. Whatever the reason, our team carries out every upgrade safely, efficiently, and with the minimum possible disruption — giving your home or business the protection it deserves. Explore our Fuseboard / Fuse Box Upgrades service.

⚡ Car Charging Points / Pods

Cardiff is one of the most EV-progressive cities in Wales, and home charging is at the heart of making electric vehicle ownership genuinely work in an urban environment. Whether you’re in a house with a driveway in the northern suburbs or a property with off-road parking closer to the city centre, a professionally installed home charge point means your vehicle is always ready to go in the morning at a cost that public charging simply can’t match. Teslec installs OZEV-approved EV charge points and pods across Cardiff — safely wired, professionally finished, and installed in the most practical position for your property. Discover our Car Charging Points / Pods installation service.

⚡ Socket Outlets

Across Cardiff’s older housing stock — and even in many newer properties — socket outlet provision rarely keeps pace with how modern households and businesses actually operate. Inner-city terraced homes in areas like Roath, Canton, and Adamsdown were wired for a fraction of today’s electrical demand, while city centre apartments and commercial spaces often need additional outlets to support home working setups, smart technology, and a growing range of permanently plugged-in devices. Our electricians install additional sockets wherever they’re needed across Cardiff, wired to current BS 7671 standards and finished cleanly to integrate with the property. Learn about our Socket Outlets installation service.

⚡ Oven / Cooker

Whether you’re fitting a new range cooker in a Cardiff family home, connecting a built-in oven during a kitchen renovation, or replacing an appliance in a rental property, the connection must always be carried out by a qualified electrician. Cooking appliances require a dedicated circuit, a correctly rated supply, and certification on completion — and without all of those elements, the installation is neither safe nor insurance-compliant. Our team manages every stage of the process cleanly and efficiently, leaving your kitchen operational, correctly certified, and ready to use before we leave. Read about our Oven / Cooker installation service.

⚡ Light Fittings / Fixtures

Cardiff homes and businesses benefit from an enormous range of lighting possibilities — and the right installation makes a real difference to how a space looks, feels, and functions every day. In the city’s period properties, well-chosen lighting complements the original architecture beautifully; in modern apartments and commercial spaces, it defines the atmosphere and working environment. LED downlights, feature pendants, bathroom IP fittings, and commercial strip lighting — our electricians install every type of light fitting right across Cardiff to a high, consistent standard. Whether it’s a single replacement or a full lighting redesign, we approach every job with the same care and attention. Discover our Light Fittings / Fixtures service.

⚡ Jacuzzi / Hot Tub / Spa / Whirlpool

For Cardiff homeowners with garden space investing in a hot tub or outdoor spa, the electrical installation is the element of the project that absolutely cannot be cut short. A dedicated outdoor circuit with full RCD protection, installed in compliance with Part P building regulations, is a legal requirement — and one that protects both the people using the installation and the value of the investment being made. Teslec carries out every hot tub and outdoor spa connection across Cardiff to the full required standard, with complete certification provided on completion so your installation is safe, compliant, and ready to enjoy from day one. Explore our Jacuzzi / Hot Tub / Spa / Whirlpool electrical service.

⚡ Electric Hob / Cooktops

Induction and ceramic hob upgrades are consistently popular across Cardiff — particularly in the city’s large student and young professional rental market, where landlords and owner-occupiers alike are upgrading kitchens to modern, low-maintenance standards. An induction hob delivers faster, more efficient cooking and a surface that’s far easier to keep clean than any alternative — and fitting one correctly requires a qualified electrician to assess the supply and install the required dedicated circuit. Our team handles the complete process in a single visit wherever the job allows, with a full test and sign-off before we hand the kitchen back. Find out about our Electric Hob / Cooktops installation service.

⚡ External Lights

External lighting improves security, safety, and the overall appearance of any Cardiff property — and across a city this size, the applications are as varied as the properties themselves. A well-positioned floodlight at the rear of an inner-city terraced house, smart entrance lighting on a northern suburbs family home, commercial perimeter lighting for a Cardiff business premises, or a PIR-activated fitting for a city centre apartment block communal area — our team installs every type of external lighting correctly wired, properly weatherproofed, and fit for purpose in the long term. Learn about our External Lights installation service.

⚡ Electrical Fault Finding

Electrical faults in Cardiff properties range from straightforward single-point failures to complex, multi-circuit issues that develop slowly across systems with long and varied histories. In the city’s older housing stock, modifications made across decades by different hands, wiring of mixed ages, and consumer units that were never upgraded to match increasing demand can all contribute to faults that are genuinely difficult to isolate without the right equipment and experience. In newer builds and commercial premises, poor original installation or growing load demands can create their own set of challenges. Teslec’s fault-finding electricians work systematically and accurately across all Cardiff property types, identifying the true root cause and resolving it definitively.
