“OSullivan Electrical rewired our whole house. Brilliant service - the team were tidy, professional, and the cert was ready before they left. Would recommend to anyone.”
“Had my EV charger installed last month. Sorted the SEAI grant paperwork, did a brilliant job, and explained everything clearly. Half a day and it was done.”
“Called them at 10pm when our power went out. They were there in under an hour, sorted the fault, and were gone before midnight. Lifesavers.”
