How Can We Help?

⚡ Fuseboard / Fuse Box Upgrades

Cathays’ Victorian and Edwardian terraces are some of the most frequently upgraded properties we work on across Cardiff. Many of these homes have been converted, subdivided, and modified over the decades — often resulting in consumer units that are outdated, overloaded, or simply not up to current safety standards. A modern fuse board with RCD and RCBO protection dramatically improves the safety of the entire property and is increasingly a requirement for landlords letting to tenants. Find out about our Fuseboard / Fuse Box Upgrades service.

⚡ Extractor Fans / Ventilation

In Cathays’ tightly packed terraced streets — where many properties are occupied by multiple tenants and cooking and bathing facilities get heavy daily use — effective ventilation is genuinely important. Without proper extraction, moisture accumulates rapidly, leading to condensation, damp, and mould that affects both the structure of the property and the health of its occupants. We install modern extractor fans in bathrooms, kitchens, and utility spaces across Cathays, quickly and with a clean, professional result. Discover our Extractor Fans / Ventilation service.

⚡ Car Charging Points / Pods

With more Cathays residents making the switch to electric vehicles — and Cardiff City Council actively encouraging greener transport choices — home EV charging is becoming an increasingly practical option even in this urban neighbourhood. For those with a driveway, garage, or off-street parking space, Teslec installs OZEV-approved EV charge points and pods safely wired from your consumer unit, making overnight charging at home simple, affordable, and completely reliable. Learn about our Car Charging Points / Pods installation service.

⚡ Oven / Cooker

In a busy Cathays household — whether owner-occupied or rented — a working oven is non-negotiable. Replacing or connecting a new oven or range cooker must always be handled by a qualified electrician to ensure the dedicated circuit is correctly rated and the connection is safe and certified. Our team carries out oven and cooker installations across Cathays quickly and thoroughly, leaving everything tested, compliant, and ready to cook with straight away. Explore our Oven / Cooker installation service.

⚡ Socket Outlets

Cathays is full of Victorian terraces that were built long before the age of laptops, phone chargers, smart TVs, and kitchen appliances on every worktop. In a busy household — particularly a shared one — the shortage of sockets quickly becomes a daily frustration and, where extension leads are overloaded, a genuine hazard. Additional properly wired socket outlets are the right solution, and our electricians install them wherever they’re needed, to current standards and with a neat finish. Read about our Socket Outlets installation service.

⚡ Electric Hob / Cooktops

Whether you’re a Cathays homeowner upgrading a kitchen or a landlord refurbishing a rental property, switching to an induction or ceramic hob is a popular and practical improvement. Before the new hob can be used safely, however, the existing electrical supply must be assessed and a correctly rated dedicated circuit must be in place. Our electricians carry out the full process efficiently — assessment, any necessary circuit work, connection, and final testing — leaving the kitchen ready to use with no loose ends. Find out about our Electric Hob / Cooktops installation service.

⚡ Light Fittings / Fixtures

Cathays’ period properties have real architectural character — and the right lighting choices can make the most of original features while bringing a home firmly into the present. Whether it’s a set of warm LED downlights in a kitchen, a stylish pendant in a bay-windowed front room, or safe, IP-rated fittings in a bathroom that’s seen better days, our electricians install all types of light fixtures to a high standard throughout Cathays. Discover our Light Fittings / Fixtures service.

⚡ External Lights

Security lighting is a practical priority in a densely populated urban neighbourhood like Cathays. A well-positioned external light — whether a PIR floodlight at the rear of the house, a lantern above the front door, or pathway lighting in the garden — makes a property noticeably more secure and more welcoming at the same time. Our electricians install all types of outdoor lighting across Cathays, correctly wired and built to perform through every season. Explore our External Lights installation service.

Electrical Fault Finding

Older Cathays properties — many of which have been modified, extended, and rewired in parts over many decades — can present particularly complex fault-finding challenges. When something goes wrong with the electrics, the cause isn’t always obvious. Our fault-finding electricians use specialist diagnostic equipment to trace the source of any electrical issue accurately and resolve it at the root, so you’re not dealing with the same problem again next month. Learn about our Electrical Fault Finding service.

⚡ Jacuzzi / Hot Tub / Spa / Whirlpool

For Cathays homeowners with a rear garden who are investing in a hot tub or garden spa, getting the electrical installation done correctly is essential. A dedicated, weatherproof outdoor circuit with full RCD protection is a legal requirement under Part P building regulations, and must be installed by a qualified electrician. Our team carries out every hot tub and spa connection to the correct standard — safely, compliantly, and ready to enjoy. Read about our Jacuzzi / Hot Tub / Spa / Whirlpool electrical service.
