In practice, yes — if your home is eligible for a smart meter, you will not be paid for the electricity you export until ESB Networks has installed one. That is the rule set out by the Commission for Regulation of Utilities (CRU): smart-meter-eligible homes are paid on actual export readings, and payments only begin once the meter is in and your NC6 form has been processed. The only homes paid without a smart meter are those that cannot technically take one — they receive a “deemed export” estimate that almost always undercounts what the panels really send to the grid.
- Have a smart meter already? You're paid on actual half-hourly export readings once your NC6 form is processed — your supplier is told automatically
- Eligible but no meter yet? No export payments until it's installed. ESB Networks aims to fit one within four months of a valid NC6 form
- Home can't take a smart meter? You're paid on a CRU deemed-export formula — roughly 1,190 kWh a year for a typical 4 kWp system
- Don't have solar yet? You can request a smart meter from ESB Networks for free at any time using their sign-up form and your MPRN
Why the Smart Meter Decides When You Get Paid
Under the Micro-generation Support Scheme, every electricity supplier in Ireland must pay you for surplus solar electricity through the Clean Export Guarantee (CEG). Standard rates currently run from 15.89c to 25c per kWh depending on supplier, with one premium tariff paying 32c in Year 1. But the CEG only tells you the rate. The smart meter decides the volume you're paid for — and whether payments have started at all.
A smart meter records your import and export in half-hour intervals, and ESB Networks shares those readings with your supplier. That is the only way your supplier can see your actual exported units. Without one, there is nothing to bill against — which is why the CRU rules work the way they do.
The Rule, in Plain Terms
| Your situation | How you're paid |
|---|---|
| Smart meter already installed | Actual export, measured every half hour. Payments start once ESB Networks processes your NC6 form — if you have a smart meter, your supplier is notified automatically |
| Eligible for a smart meter, not yet installed | No export payments until the meter is in. ESB Networks aims to install one within four months of a valid NC6 form, and contacts you ahead of the exchange |
| Home technically can't take a smart meter | Deemed export: a CRU formula estimate paid at your supplier's CEG rate, no meter readings involved |
Note what's missing from that table: an option where an eligible home skips the smart meter and still gets paid. There isn't one. Eligibility for export payment is determined by the CRU, and for homes that can take a smart meter, actual-read payment through that meter is the route.
The Deemed Export Estimate — and Why It Pays Less
Homes that cannot take a smart meter are paid on a standardised estimate calculated by ESB Networks using a CRU formula: your system's registered capacity × 9.7% (an assumed capacity factor) × 35% (the assumed share of generation that gets exported) × the hours in the payment period. For a typical 4 kWp system, that works out at roughly 1,190 kWh a year.
Compare that with what a real 4 kWp system exports — typically around 1,400 kWh a year, and more in homes that are out during the day. The deemed estimate undercounts, and it pays the same whether your panels face south or north, so there is no upside to staying on it. If your home is eligible for a smart meter, the meter nearly always pays better — and for eligible homes it isn't optional anyway.
How to Get a Smart Meter
Route 1: You're installing solar — the NC6 form triggers it
When your installer submits the NC6 microgeneration form to ESB Networks (used for single-phase systems under 6 kW and three-phase under 11 kW — larger systems up to 50 kW use the NC7), the smart meter exchange is set in motion automatically. Where the home is eligible, ESB Networks aims to install a smart meter within four months of the valid form being processed, and they contact you in advance of the exchange — you don't need to chase it. There's no charge to connect a micro-generator up to 6 kVA single phase, and the meter exchange itself doesn't cost you anything.
Route 2: You don't have solar yet — request one directly
The national rollout is still working through the meter stock, and you can put yourself in the queue rather than waiting to be scheduled. ESB Networks runs a Smart Meter Sign Up Form where households can request a meter. You'll need your MPRN — the 11-digit Meter Point Registration Number on your electricity bill, starting with 10. ESB Networks then contacts you about next steps; the timing of the exchange still depends on the rollout in your area and whether your existing meter setup is ready for a straight swap. Requesting the meter before your panels go in means the export-payment clock can start as soon as your NC6 form is processed, rather than waiting on a meter exchange afterwards.
We match you with SEAI-registered installers in your county — they handle the NC6 form and the grant paperwork, and the smart meter exchange follows automatically. Free, no obligation.

Once the smart meter is installed and your NC6 form is processed, your supplier pays you their CEG rate on every kWh you export, based on the half-hourly readings. Export income generally appears as a credit on your electricity bill, though some suppliers issue a separate statement. Two things worth knowing about the money:
- Rates vary widely by supplier. The gap between the lowest and highest standard CEG rate is worth around €128 a year on a typical system — our CEG rate comparison tracks who pays what.
- The first €400 a year is tax-free. A Revenue exemption covers micro-generation income up to €400 per year until the end of 2028 — our guide to tax on solar export income covers what happens above that.
One thing the export payment does not depend on is the age of your home. The Clean Export Guarantee is open to all registered microgenerators — a new build qualifies just like an older house, and there's no minimum BER requirement. The built-before-2021 rule you may have read about applies to the €1,800 SEAI grant, not to getting paid for export — our guide to solar grants for new builds covers that distinction.
Frequently Asked Questions
If your home is eligible for a smart meter, yes — you will not receive export payments until ESB Networks installs one. Payments begin once the smart meter is in and your NC6 microgeneration form has been processed. Only homes that cannot technically take a smart meter are paid without one, on a deemed-export estimate set by the CRU.
ESB Networks aims to install a smart meter within four months of a valid NC6 form being processed, where the home is eligible. They contact you in advance to arrange the exchange — you don't need to apply separately once the NC6 is in. If you want to remove the wait entirely, you can request a smart meter through the ESB Networks Smart Meter Sign Up Form before your panels are installed.
Use the Smart Meter Sign Up Form on the ESB Networks website. You'll need your name, address, Eircode and your MPRN — the 11-digit Meter Point Registration Number printed on your electricity bill, beginning with 10. There is no charge for the meter exchange. ESB Networks contacts you about next steps; the installation date depends on the rollout in your area and your existing meter setup.
Payments don't start until the meter is installed, so export during a long wait is the main thing at stake. The practical answer is to get the NC6 form in promptly (your installer normally submits it as part of the job) and, if you don't yet have a meter, request one directly so the exchange isn't waiting on the rollout schedule. Your panels still cut your bills from day one — it's only the export payment that waits for the meter.
It records both the electricity you import from the grid and the surplus you export, in half-hour intervals. ESB Networks shares the export readings with your supplier, who pays you their Clean Export Guarantee rate per kWh. You can also see your own usage and export data through your ESB Networks online account.
Homes that are technically unable to take a smart meter are paid on a deemed estimate calculated with a CRU formula: registered system capacity × 9.7% × 35% × the hours in the payment period — roughly 1,190 kWh a year for a 4 kWp system, paid at your supplier's CEG rate. Real systems usually export more than the estimate assumes, which is why actual smart meter readings nearly always pay better.
