Every domestic solar PV system connected to the grid in Ireland needs an NC6 notification. For installers it is one of the most repetitive pieces of paperwork on every job, and one of the easiest to get wrong. Here is a clear guide to how the process works and how to keep it moving.
What is the NC6 form?
The NC6 is ESB Networks’ notification form for micro-generation. It tells ESB Networks that a small generator, such as a rooftop solar PV system, is being connected to the low-voltage network at a property.
Which systems qualify?
The NC6 route covers micro-generators of up to 25A on a single-phase connection (about 6kW) and up to 16A on a three-phase connection (about 11kW). Larger systems follow a different application process.
When must it be submitted?
ESB Networks asks for the NC6 to be submitted before installation. If ESB Networks tells you within its stated timeframe that the installation cannot proceed, work should not start.
What do you need?
- The completed NC6 form with customer, site and MPRN details.
- System details, including inverter make, model and rating.
- A type test certificate showing the inverter complies with IS EN 50549-1.
Applications are made online or by post. ESB Networks no longer processes emailed applications.
Who is responsible?
The installation must be carried out by a registered electrical contractor to Safe Electric standards. In practice, the installer’s registered electrician reviews and signs off the paperwork for each job.
Where NC6 paperwork goes wrong
- Missing or mistyped MPRNs and Eircodes.
- Inverter details that don’t match the type test certificate.
- Forms prepared late, after the install date is already booked.
- No clear record of which jobs are submitted, pending or complete.
How to take NC6 paperwork off your desk
WattScribe compiles each NC6 pack from the job details you already hold, flags anything missing before it reaches review, and sends it to your registered electrician to check, sign and submit. Every pack is stored against the job, so you always know where each one stands.
