Gareth's service was excellent — he came on time, kept me updated via text of what time to expect him, installed the light fitting with the minimum of fuss and I feel was great value for money. No complaints, will use again.

Recently had a full rewire. Gareth and his team were professional from start to finish and kept you up to date at every opportunity. They tidied up at any given time, along with wearing coverings for their footwear, so much respect for our home.

We required electrics (plug sockets, lights, infrared heater, Ethernet) installing in our shed to office conversion, as well as installation of mains fire alarms and an EICR of the property. Cardiff Electrical professionally completed the work on time and on budget.

About Us

Gareth Birch

Owner & Rewiring Specialist

About Cardiff Electrical Home Rewire Ltd

At Cardiff Electrical Home Rewire Ltd, we believe homeowners deserve a specialist service when it comes to the safety and reliability of their home's electrical system.

My name is Gareth Birch, and I founded Cardiff Electrical Home Rewire Ltd with a simple goal: to provide professional, high-quality rewiring services across Cardiff and South Wales. After working in the electrical industry for many years, I saw that complete house rewires were often treated as just another job. In reality, a rewire is one of the most important investments a homeowner can make, affecting the safety, functionality, and future value of their property.

Rather than offering every electrical service under the sun, I chose to focus on what I do best — house rewires, consumer unit upgrades, electrical inspections, and electrical installations that bring older properties up to modern standards.

As a homeowner, it can be difficult knowing who to trust. That's why I built this business around honesty, clear communication, fair pricing, and quality workmanship. From the initial survey through to completion and certification, I aim to make the process as straightforward and stress-free as possible.

Over the years, I've helped homeowners across Cardiff, Newport, Caerphilly, Pontypridd, Barry, Penarth, Bridgend and the surrounding areas modernise their electrical systems and improve the safety of their homes. Every project is approached with the same attention to detail and care that I would expect in my own property.

As a NICEIC Approved Contractor, all work is carried out to current BS 7671 Wiring Regulations and fully tested and certified upon completion. Whether you require a full house rewire, partial rewire, consumer unit replacement, or an Electrical Installation Condition Report (EICR), you can be confident that your project is in safe hands.

My reputation is built on customer satisfaction, quality workmanship, and delivering reliable electrical solutions that stand the test of time.

If you're looking for a trusted local electrician and rewiring specialist in Cardiff, I'd be delighted to discuss your project and provide honest advice with no obligation.

Why Choose a NICEIC Electrician for House Rewiring?

House rewiring is the most significant electrical work you can undertake in your home. It involves replacing all wiring, sockets, switches, lighting circuits, and often the consumer unit. Only a NICEIC-registered electrician can guarantee this work meets current safety standards, is properly certified, and carries an insurance-backed warranty. Non-certified rewiring can invalidate your home insurance, fail building control approval, and create serious safety risks.
