Fire Alarm Installation & Fire Alarm Maintenance

Emergency call out - couldn't recommend Brian and his service more. He was out to us within an hour and a half on a BH Sunday & issue rectified & made safe. Thank you Brian.

Honestly, an amazing service and Brian was so so lovely. From the minute I rang him he was so good to run through things with me before even calling out. 2 days before christmas at 7 in the evening and he came out to us in less than 2 hours and went through everything with a fine tooth comb! Turns out it was problem from ESB and he could have just left then but instead he rang them with us, spoke to the woman on the phone, explained everything and made sure we were good before he left. Just an overall lovely guy and he was so professional and thorough. Even gave us information on how to claim back the call out charge from ESB which he didn't have to do. Would highly recommend!! ⭐⭐⭐⭐⭐

Today after I made an emergency call to Brian on behalf of my parents, he was there within an hour to help them. Brian has been before and I cannot thank him enough for his professional and personal service, a gentleman. Thank you sincerely. From Ruth Breathnach

I would highly recommend Dylan, Brian and the team . I rang with a very urgent problem and it was handled straight away with the best quality and I am now at ease in my home thanks to them . Couldn’t be more grateful. Thanks again to ye all

Fantastic service, very helpful, knowledgeable & tidy - thanks a million !

Brian arrived exactly when he said he would. Very professional, got power on after finding fault very quickly. Would highly recommend this company. Excellent service.

This is the guy to have at your home. Explained everything that was going on and kept me up to date on approx pricing of everything. Genuinely couldn’t recommend highly enough. Clearly highly competent and enjoys talking about his work. A credit to the industry that often has a bad rep!

Thank you Brian for being so helpful and professional. After a local power cut Bryan talked me through instructions to restore power. Really appreciate your help. Would not hesitate in recommending Brian to anyone in need of a trustworthy electrician. Jacqueline

Thoroughly professional. Detailed and on time service. Thanks to Brian and Dylan that we could finish whole house re-wiring on time. Also special mention for Tristan the electrician who spent most hours doing the whole electrical work.

Great service...phone advice...

Fantastic service we have used several times. Always very quick to respond, professional and good value. Can’t recommend highly enough.

Great service. Fast and efficient.

Amazing experience! Called up during the night, and Brian was here in half an hour. He was so kind and really professional, went totally above and beyond for us. He was very patient and took the time to make sure I understood every step of what he was doing, while cracking jokes to put everyone at ease. I was thrilled with everything he did, and would highly recommend this service. Thank you Brian!

021Electrician provided an excellent, professional service. I am very impressed with their efficiency, reliability and the quality of service they have provided to our home in a time of need. I will certainly be using them again and would not hesitate in recommending them to anyone. Very happy with their service.

I was having a very stressful time with an Electrical issue. Had dealt with other electricians who were basically no help at all. Eventually I found 021 Electrician and they saved the day! Brian came round and solved the issue in about an hour! Himself and the lad he works with were extremely professional, efficient, informative and friendly. I am very thankful to them and will definitely use them again in future if any more issues pop up (fingers crossed that's not for a long time though! Haha). In summary... I highly recommend 021 Electrician!

Great service. Punctual and professional. Would highly recommend 021 Electrician.

This absolute hero saved me a lot of time, money, and stress with a simple phone call, he knew instantly what the problem was and what the solution was, didn’t even need to call out and was happy to help over the phone. I honestly couldn’t recommend this service any more and I wouldn’t even think about going to anyone else if I had any other problems in the future! 👍🏻👍🏻

We had work done in our own house and my father's house and we highly recommend 021 Electrician. Brian and Dylan and the team were a pleasure to work with. When they give you a time and day for work they will be there and on time. From changing light fixtures to wiring no job was too small. So my opinion and my father's opinion we would highly recommend them.

Excellent service. Would highly recommend.

Absolutely delighted with Brian and his team on a full rewire of our 100 year-old terraced house. We had no idea what we were getting in to but from start to finish Brian was a great communicator, going through everything with us that we needed and wanted, explaining everything really clearly and giving us great advice. He was super professsional, considerate and the work was immaculate. He made what could have been a very stressful process so much easier and enjoyable. We can't thank him enough for all he did for us! Thanks so much as well to Dylan, for his endless patience and answering all of our millions of questions! The whole team was amazingly helpful and accommodated our every need. I would highly recommend Brian and his team!

Brian and his team did excellent job in our house. Strongly recommend

Exceptional Service When We Needed It Most! Lifesavers During a Home Renovation Nightmare! It’s not often you feel a company truly earns a glowing review—but 021 Electrician absolutely has. My wife and I had funded the renovation of my mother-in-law’s house ourselves, upfront, pending reimbursement through a government grant once the work was complete. Unfortunately, we were left in serious financial difficulty after discovering the builder had used unqualified labour and couldn’t certify the electrical work—meaning no grant payout. That’s when Brian and the 021 Electrician team stepped in. They were professional, courteous, and totally transparent from the start. They condemned the faulty work, corrected every issue to the highest standard, and kept us informed at every step. They even tidied up after themselves each day and handled all the paperwork needed to issue the vital certificate. Their integrity, efficiency, and care made all the difference. My wife and I are beyond grateful and can wholeheartedly recommend 021 Electrician to anyone. Thank you, Brian and your team—you truly saved the day!

Had a power cut and contacted Brian (who's done previous jobs) early in the morning. He responded in minutes advising what the issue could be, and he was right. Saved us a huge amount of hassle and I could not recommend him highly enough. Prompt, great communication and feedback. I am happy to recommend Brian and his team, again, to my friends and family. Thanks again Brian.

021 have worked in my home a number of times They are efficient, friendly and most importantly very knowledgeable and Safety conscious. They are also forward thinking and advise me on new products. I wouldn't trust anybody else and I highly recommend them.

Our electricity went out on Saturday 28th of December it was pandemonium left in complete darkness the kids were frightened. Did all the checked on the fuse board unplugged the item that blew the electricity out We rang 021 electrician Brian he very kindly talked us through the problem over the phone it was out was our outside switch had tripped he was extremely quick to respond to our dilemma as you could imagine we would have had no electricity until Monday it would have been awful We really appreciate your quick helpful service we could not recommend Brian highly enough thank you so much for your service

Very professional, helpful in emergency situation and very responsive. Can’t recommend anyone else but Brian!

Dylan, Brian & their team recently carried out a re wire of our home. They were professional, efficient, punctual & friendly. Always going the extra mile to ensure that all works were completed to the highest standard & always contactable. We are delighted with the job. Would highly recommend. Five star service. Thanks lads.

Mystery power outage on a Saturday night, googled emergency electrician and call was answered first time and a solution provided over the phone, with no charge. Very kind and professional. Will definitely use for work in the future

Highly, highly recommended. Brian was really quick to respond, incredibly professional and helpful. He and his team did an amazing job

Top class, efficient and professional

Contacted them late in the evening. Brian was very helpful and on time over the phone.

I had to rewire my house and Brian and his team took over the project. I can be happier with the job they did and how he managed the whole process, keeping me updated and being available all the time for questions and last minute requests. I would recommend Brian to anyone in Cork area, what it could have been an awful experience he made it easy and smooth. Thanks so much.

Brian O'Sullivan was very professional to deal with, going out of his way to help out on a bank holiday weekend. Fully recommend

Found Brian's details online after our electricity went at 9pm on a Sunday night. Brian was available to call but we chose to wait for ESB as we believed the fault was external. Brian offered very helpful advice over the phone while we were waiting. Great to know this service is available. Especially in the case of emergencies. Thanks Brian 😊

We had a powercut late at night, and given that we had a child with special needs it became an emergency. After calling a number of ‘24 hour services’ and getting nothing back, I contacted Brian and the call was answered immediately. He triaged what was going on to see if he could fix it over the phone and when that failed he was with us in less than an hour. Brian is knowledgeful, professional and had power back in 10 minutes. I can’t recommend this service enough.

Brian has come to fix different electricity issues and replace appliances in my apartment several times. Always good communication, fast response and never had any issue with the work he's done for me. Highly appreciated especially during the time when all the electrician are hard to book appointments. Recommended without any hesitation.

We recently hired 021 Electrician to handle all the electrical work for our new build, and the experience was nothing short of exceptional. From the first consultation to the final walkthrough, their professionalism, attention to detail, and deep technical expertise were evident at every stage. They ensured that all wiring, lighting, outlets, and safety systems were not only up to code but tailored perfectly to our design needs. What stood out most was their ability to offer smart, energy-efficient solutions without compromising on style or functionality. Clean, reliable, communicative, and clearly passionate about their craft, Dylan and his team delivered top-tier workmanship. We feel incredibly confident in the quality and safety of our home’s electrical system thanks to their outstanding work. Dylan and his team went above and beyond for us, we are very grateful to have such an amazing team work on our new build. Highly recommended for anyone looking for a skilled and trustworthy electricians.

Great service very professional, job well done.

Dylan and tram were great to deal with. Very prompt and professional. Highly recommend their services

Brian came out on the worst possible Saturday night, when there was the rugby world cup match between Ireland and New Zealand. We rang him because our electricity went off, the fuse box was stuck and there was no way to reactivate it. He arrived less than 2 hours after the call, which was great in such a night. Brian's service was very professional and quick. He changed the main switch box in 5 minutes while explaining everything to us and was very kind. We have found our trusted electrician for the future. Many thanks,Brian! Silvia and family

I had an emergency last Saturday night, and Brian had someone at my door literally within 45 minutes. Job completed very quickly by a polite & friendly young man who accomodated the fact that my autistic son would find his presence intrusive. I cannot recommend this service highly enough. Thank you so much for being immediately available during unsociable hours and for being so kind.

Absolutely first class response from Brian and 021 Electrician on December 28th, over the phone he advised us step by step what to do after our electricity went out and no response from the fuse board or main switch,we have 2 toddlers under 4 who couldn't understand why we had no lights or tv but in a matter of minutes he sorted the problem and saved our weekend, especially when it was just after Christmas. Much appreciated and top class service, a sound man. Couldn't recommend him and his team more highly. Thanks.

Emergency Call Out Thanks so much to Brian for sorting out our power outage. He clearly explained the cause and other issues that were wrong with the fuse board, that could have potentially resulted in more serious problems. Replaced main switch fuse & RCD, relocated and rerouted wiring, made safe previously installed fuses and switch units, all in all a safer fuse board that gives peace of mind. Speedy response and professional job done, very grateful for his service.

Brian, and team are electric wizards! Work extremely quickly, and efficiently and left the place in an immaculate state afterwards. Would highly recommend for big and small jobs. Not only is Brian very friendly and approachable, he’s willing to answer any other questions too that aren’t relating to the job at hand. We would 100% use 021Electrician again in the future.

Professional and efficient service

Called and spoke to Brian , he was there in less than an hour. Replaced and fixed everything and my mum was super happy with the work and thought Brian was a lovely man 5 stars ⭐️

The most perfect and professional job. Brian make sure that everything was perfectly working and completely safe before leaving. Highly recommended!

Awesome work done! Called this morning and they could come in the afternoon, very professional and could explain the cause of the issue and provide recommendation. We will definitely call them again if needed. Thank you!

Brian came out on a cold Sunday to fix our power. Arrived when he said he would, fixed the issue and gave great advice. Would highly recommend the service

Can't recommend Brian and his team highly enough. Very professional and a pleasure to deal with especially the 2 Jakes.
