Why Electrical Tails Matter for EV & Solar Installations
When it comes to EV home charger installation or solar panel installation in Ireland, most homeowners focus on the big equipment: the charger, the panels, the inverter. But there’s one small but critical part of your electrical setup that could hold everything back—the meter tails.
These insulated copper wires connect your home’s electricity supply to your main fuse board. If they’re too small, they can overheat, fail safety tests, or simply not carry the load required for modern electric car charging points or solar PV panels. In Ireland, especially in houses built before the mid-1990s, upgrading to at least 16mm² tails is often a must for safety and compliance.
What is a Tails Upgrade and Why Do You Need It?
A tails upgrade involves replacing or extending the cables that bring power from the ESB meter to your main fuse board. While they might look unimportant, they’re essential for safely delivering electricity from the grid into your home.
If you’re installing an EV charger or solar photovoltaic panels, the National Rules for Electrical Installations (I.S. 10101:2020 + A1:2024, Part 722) require tails of at least 16mm². Anything smaller risks overheating and doesn’t meet Irish electrical safety standards.
Stage 1: Site Visit & Insulation Resistance Test (IRT)
Before any upgrade, ePower carries out a home visit to test your wiring’s insulation. This Insulation Resistance Test ensures your electrical system is safe from faults that could cause shocks or fires.
During the visit, our Safe Electric-certified team reviews your full electrical setup and produces a detailed report. The quote you receive will reflect the amount of 16mm² cable required and any other upgrades needed—such as main fuse replacement, surge protection, or earth rod installation.
Cost: €205 + VAT for the Stage 1 site visit. If the IRT fails, faults must be fixed before proceeding with the tails upgrade.
Stage 2: Tails Upgrade & Certification
Once you approve the quote, we:
- Replace your meter tails with 16mm² cables.
- Fix any IRT-related issues.
- Carry out any additional safety upgrades.
- Perform a Post-Connection Test.
- Submit a Cert One to Safe Electric (you’ll get a copy).
You’ll then contact ESB Networks (1800 372 757) with your MPRN and Cert One details. ESB charges approx. €200 for the tails connection. Once your ESB appointment is booked, ePower schedules Stage 3.
Stage 3: Final Test & Certification
An ePower-partnered electrician will be on-site during the ESB visit to connect the new tails. We’ll then run a final safety check and issue your Completion Certificate.
This ensures your home is fully compliant and ready for home EV charging or solar panel installation—with no electrical bottlenecks holding you back.
Why a Tails Upgrade Future-Proofs Your Home
By upgrading your meter tails now, you’re not just making your home safe for today’s EV chargers and PV panels—you’re preparing for future energy demands, from heat pumps to battery storage systems.
It’s a small investment that avoids the frustration of failed inspections or last-minute delays during your electric car charger or solar power installation.

FAQ – Tails Upgrades, EV Chargers & Solar Panels in Ireland
You may need a meter tails upgrade first to meet Irish safety standards and SEAI grant requirements. This FAQ answers the most common questions about tails upgrades, electrical capacity, and how to prepare your home for electric car charging and solar PV systems.
Do I need a tails upgrade for an EV charger in Ireland?
Yes. If your meter tails are smaller than 16mm², you will likely need a tails upgrade before installing a home EV charger. This ensures your system can handle the higher current required for fast, safe electric car charging and meets Irish electrical standards (I.S. 10101:2020).
What size meter tails are required for solar panel installations in Ireland?
For most residential solar PV systems, the National Rules for Electrical Installations require meter tails of at least 16mm². This allows your system to safely handle the additional generation from solar panels without risk of overheating or electrical failure.
How much does a tails upgrade cost in Ireland?
Costs vary depending on cable length and any additional safety work required. At ePower, a Stage 1 site visit and Insulation Resistance Test costs €205 + VAT. ESB Networks charges approximately €200 for the connection. Final pricing depends on your home’s specific requirements.
Who is responsible for upgrading meter tails in Ireland?
Your Safe Electric-registered electrician (such as ePower) will install the new tails inside your property and issue a Cert One. ESB Networks then connects the upgraded tails from the meter to your fuse board. Homeowners are responsible for booking the ESB visit.
Can I apply for SEAI grants if I need a tails upgrade first?
Yes. As long as your EV charger or solar panel installation meets SEAI’s requirements, having a tails upgrade first won’t affect your eligibility. In fact, ensuring your system is compliant helps avoid grant payment delays.
What happens if I don’t upgrade my meter tails?
If your meter tails are undersized, your EV charger or solar PV installation may fail safety checks. This could result in project delays, extra costs, or even refusal of ESB connection until the upgrade is completed.
So, if you’re planning an EV charger installation in Ireland or fitting solar panels in Dublin or nationwide, talk to ePower first. We’ll check your electrical system, handle any tails upgrade, and guide you through SEAI grants—so your installation is safe, compliant, and future-ready.
