About 021 Electrician

 

021 Electrician was founded by Brian O’Sullivan in 2005 and has since grown into one of Cork and Munster’s most trusted electrical contractors. From its beginnings as a small operation, the company now delivers safe, reliable, and forward-thinking electrical solutions across the domestic and commercial sectors.

In 2024, Dylan Murphy joined as co-owner, bringing with him over a decade of experience in the electrical trade, including 10 years specialising in solar installations, as well as expertise in heat pump installation, servicing, and maintenance. His strong background in renewable energy systems and sustainable technologies has broadened the company’s capabilities and positioned 021 Electrician as a leading provider of renewable energy solutions in Cork and beyond.

Since Brian and Dylan came together at the helm, the company has doubled in size, a reflection of their shared commitment to innovation, high-quality workmanship, and customer trust.

Both directors hold QC Registration Numbers with Safe Electric and are dedicated to continuous professional development, having completed advanced training in smart home automation and solar PV system design and installation. Alongside their skilled team, they are also SEAI-approved Microgeneration (MicroGen) Registered Contractors, ensuring that all solar panel installations in Cork and Munster meet the highest safety and efficiency standards.

As of August 2025, 021 Electrician directly employs more than 20 full-time staff across Cork and Munster. The company also works in close partnership with Sean Richardson of Complete Plumbing Solutions and Anthony O’Leary of A. O’Leary Roofing & Renovations. Together, this alliance provides a combined workforce of over 40 full-time staff, with further access to a nationwide network of trusted subcontractors covering all trades — making 021 Electrician the go-to choice for full-service electrical and energy solutions in Ireland.

Over the years, 021 Electrician has built strong and lasting relationships with homeowners, housing bodies, commercial facilities, and national organisations, consistently delivering dependable, end-to-end solutions for projects of every scale.

A trip switch went off on Sunday night around midnight. All lights went out & burglar alarm went off. I tried to turn on relevant trip switch but it would not turn back on. I had to do something as next door neighbour had leaving cert exam next day. I knew it would be expensive to get an electrician in an emergency but had no choice. I googled “electrician cork emergency”. The first 24 hour service number I rang just rang out & nobody rang back. The second number I rang was 021 Electrician and Brian answered within a few rings. I explained problem & he said that if he had to call out he would have to charge so he would talk me through fix. First suggestion did not work so Brian kept going with more suggestions until lights came back on & alarm went off. I was very thankful & insisted on paying but Brian would not take any money. Unbelievable service!! I will definitely use 021 Electrician in future

A special thank you to all at 021 Electrician for their amazing work during a recent solar install and electrical upgrade. Very professional work done by Killian, Cian & Kian. These lads were a pleasure to have in our home. The whole experience was seamless due to their time, efforts and workmanship on the job. We could see care and attention taken which was reflected in the final results. Delighted to have our home retrofitted. Also, thank you to Brian in the office for being so kind and helpful.

We have just had 021 install Solar Panels for us. The process with them from start to finish was ultra professional. Dylan and Brian went through everything beforehand, they took care of installation, Grant Application and the BER cert. Dom, Pa, Cian and Luke are brilliant tidy electricians, Mark who mounted the panels was also excellent. For anyone thinking of getting Solar Panels installed or need any other electrical work done I highly recommend @021electrician. Pat & Helen O Sullivan

I had Luke the election out last Friday. Found him extremely helpful and professional in the work that he done. He went out of his to help with extractor hood I was installing. So I would highly recommend 021 as a service.

Got a solar pv panel and battery installation from 021 Electrician in April 2026. Good experience with this company - Dylan, Brian and the lads were great to deal with. Turned up on time when they said they would, did the work to Safe Electric and SEAI standards, sorted the SEAI grant for us and did the ESB Networks NC6 application for microgeneration export. 021 Electricians were great to deal with throughout. Will continue recommending them and best wishes to all working there.
