When renovating your home, electrical safety should be one of your top priorities. In Ireland, all electrical work must follow strict rules set out in the National Rules for Electrical Installations (IS 10101:2020). These rules are overseen by the Commission for Regulation of Utilities (CRU) and monitored by Safe Electric to keep homes safe and up to standard.
Whether you’re rewiring a room, adding new sockets, or installing modern systems like EV chargers or solar panels, compliance is essential. Ignoring these regulations can lead to safety risks, failed inspections, or even insurance issues.
In this blog, we’ll explain how to comply with Irish electrical regulations when renovating your home and keep your project safe, legal, and up to standard.
Irish Electrical Rules and Who’s Responsible for Safety
Electrical safety in Ireland follows strict national standards to keep homes safe and prevent electrical risks. Before starting renovation work, it helps to know which organisations manage and monitor electrical safety across the country.
1. IS 10101:2020 Rules
These are Ireland’s main electrical standards. They cover how wiring is designed, installed, and tested. Every new or upgraded system must follow these rules to stay safe and reliable for daily use.
2. CRU
The Commission for Regulation of Utilities (CRU) is Ireland’s main energy regulator. It sets safety standards and ensures all contractors follow the correct electrical procedures. The CRU also oversees Safe Electric and deals with any issues related to unsafe or uncertified work.
3. Safe Electric
Safe Electric checks that electricians meet safety rules and carry out proper work. It handles inspections, provides guidance, and ensures contractors follow IS 10101:2020 at all times.
4. Registered Contractors
Only electricians registered under Safe Electric can legally carry out most domestic electrical work. They are trained to current standards and can issue certificates confirming the work meets Irish regulations.
Why Electrical Compliance Is Crucial During Renovations?
During home renovations, it’s easy to focus on design and decoration while overlooking the electrical side of the project. However, even the smallest changes to wiring or fittings must meet current Irish safety rules. Following proper regulations helps keep your home safe and ensures your renovation passes all inspections without issues.
1. Small Jobs Still Need Compliance
Adding a new socket, moving a light switch, or updating old wiring might seem simple, but these are all regulated electrical tasks. They must be completed by a Safe Electric–registered contractor who understands the latest Irish standards. This prevents faults and helps avoid hazards once the work is finished.
2. Safety Risks of Poor Electrical Work
Electrical work that is not carried out correctly can lead to serious safety problems. Faulty wiring or missing protection devices can cause shocks or fires, putting your home and family in danger. Compliance ensures every connection, wire, and fitting meets the required level of safety.
3. Insurance and Legal Problems
If electrical work is not certified by a registered contractor, your home insurance may not cover any related damage. In addition, uncertified work can cause legal problems when selling your property. Having the correct certification proves that your home meets national safety standards and protects you from future complications.
Key Electrical Rules You Must Follow
When renovating your home, following the right electrical rules is essential for safety and legal approval. These standards are in place to protect both homeowners and electricians while keeping every installation up to the latest Irish requirements.
Below are the main rules you should be aware of during your renovation project.
1. Hire a Registered Electrical Contractor
Only a Safe Electric–registered contractor is allowed to carry out or certify most domestic electrical work in Ireland. They are trained to work according to IS 10101:2020 standards and know how to complete installations safely.
Always check a contractor’s registration before work begins to make sure your project stays compliant.
2. Certification and Testing
After any electrical work, you must receive a Completion Certificate from your contractor. This document confirms that the installation has been tested and meets Irish safety standards.
Without this certificate, your renovation work is not legally recognised and could fail future inspections.
3. RCD Protection for Lighting Circuits
Under the latest rules, Residual Current Devices (RCDs) must be fitted on lighting circuits in domestic homes. These devices protect against electric shocks by cutting off power when they detect a fault.
Having RCDs installed is now a basic requirement for all new or upgraded lighting systems.
4. Arc Fault Detection Devices (AFDDs)
Arc Fault Detection Devices (AFDDs) are recommended in high-risk areas such as bedrooms, attics, or timber-frame houses. They detect faults that could cause electrical fires and automatically shut off the supply before damage occurs.
Including AFDDs in your renovation adds an important extra layer of protection.
5. EV Chargers and Solar Systems
If your renovation includes new technologies like electric vehicle (EV) chargers or solar PV systems, they must also follow IS 10101:2020 standards. These installations need correct wiring, earthing, and isolation to work safely.
A registered electrician will make sure your system is installed properly and meets all current Irish regulations.
Conclusion
Following Irish electrical regulations is essential for a safe and compliant home renovation. From hiring a Safe Electric–registered contractor to ensuring your wiring and fittings meet IS 10101:2020 standards, each step helps protect your home and family. Taking shortcuts with electrical work can lead to safety risks, insurance problems, and failed inspections.
