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.

Our electricity went in the house after 9pm on a Wednesday night — not ideal with a sick young child! Brian answered the phone immediately and had the issue resolved without any fuss at all. He was very thorough — quick to diagnose, clear on what was wrong, and had everything back up and running in no time. Amazing service from 021 Electrician — would thoroughly recommend.

Called late on a Saturday night after losing all electricity. Brian responded immediately and did basic checks over the phone to ensure a call out was needed. He arrived very quickly and was able to quickly diagnose and fix a burning mains wire which was a serious hazard. He was very thorough in doing additional checks and testing afterwards to ensure there was no additional immediate hazards. Would highly recommend for any issues!

We went with 021 Electrical through the community solar scheme for our estate, and they've been excellent from start to finish. Brian put the proposal together and it was clear and properly costed — including the remedial electrical work our house needed before the system could go in, all itemised up front with no surprises later. They handled the SEAI grant side without fuss. Killian was our electrician and he was absolutely brilliant — knew exactly what he was doing, explained everything as he went, and nothing was a bother. The whole crew were incredibly clean and tidy too. You genuinely wouldn't have known they'd been in the house — not a bit of mess left behind. The system was up and running as promised, and they took the time to walk us through the settings so we could make the most of night-rate charging. Would recommend them to anyone considering solar in Cork
