Dun-TecRECI-Registered Electrician in Castleknock, Co. Dublin

Dun-Tec is a RECI-registered electrical contractor (Safe Electric reg. A4309) based in Castleknock, Co. Dublin. Registration under the Safe Electric scheme is a legal requirement for notifiable electrical work in Ireland, so Dun-Tec can self-certify their work and issue completion certificates directly to homeowners.

Under Irish law, certain electrical works, including consumer unit replacement, new circuits, extensions and rewires, are classified as notifiable works and must be carried out by a RECI-registered contractor. Using an unregistered electrician for these jobs means you cannot get a valid completion certificate, which is required by insurers, mortgage lenders and when selling your home.

Dun-Tec holds a current Safe Electric registration and can carry out all notifiable works in Co. Dublin in full compliance with ET101, the National Rules for Electrical Installations. Landlords can request periodic inspection reports for rental compliance, and homeowners get a completion certificate with every notifiable job.
