Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Does Onecall Electrical and Plumbing only do solar PV panel installation?
On the SEAI register they are listed for solar PV panel installation. They may well do other work, but solar PV panel installation is the measure their registration covers, so it is the one they can process a grant for.
Should anything be done before the installation?
Insulation comes first on any home energy upgrade. A well-sealed house needs a smaller system and runs at a lower cost, and attic and wall insulation carry SEAI grants of their own. Ask about the fabric of the house when you speak to Onecall Electrical and Plumbing.
What grant can I claim on work by Onecall Electrical and Plumbing?
Grants may be available for eligible homes. SEAI lists support of up to €1,800 for solar panels as of July 2026, and SEAI decides eligibility. Confirm how the application and payment work with Onecall Electrical and Plumbing and with SEAI before any work starts.
The Other Trades a Cork Retrofit Needs
A renewable heating upgrade rarely happens on its own, and the order the work goes in decides what it costs. These are SEAI-registered trades covering Cork on our sister sites, each one worth lining up before the heating work starts rather than after.
- While the scaffolding is up Roofers in Cork If external wall insulation is going on, the scaffolding is already up and paid for. That is the cheapest time to deal with the roof, and solar panels want a sound roof under them.
- Alongside the installation Electricians in Cork A heat pump needs its own supply and isolator, and solar panels need the inverter tied into the consumer unit and the ESB notification handled. Both are electrician work.
SEAI Heat Pump Grant for Work by Onecall Electrical and Plumbing
SEAI support for a heat pump is up to €12,500 (as of July 2026) for eligible homes. Ask Onecall Electrical and Plumbing how the grant application and payment would work for your job, and confirm the details with SEAI before any work starts.
It is worth knowing how the total breaks down before the survey. The heat pump itself carries €6,500, a Renewable Heat Bonus applies where you are replacing an oil, gas, solid fuel or electric storage system, and a further amount goes towards heating system upgrades such as new radiators. Asking for the quote to set those out separately makes the net figure clear rather than leaving it to be worked out later.
