What areas does Diarmuid Walsh Plumbing and Heating cover?
Diarmuid Walsh Plumbing and Heating is based in Galway and takes work across the county, including Galway city, Oranmore, Athenry, Tuam, Ballinasloe, Loughrea, Clifden and Salthill. Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Do I need to use an installer based in Galway?
No. SEAI registration is national rather than county by county, so a contractor listed under a neighbouring county can quote for your home and handle the grant the same way. Getting two or three quotes is the only reliable way to see what the work should cost.
Does Diarmuid Walsh Plumbing and Heating only do heat pump installation?
On the SEAI register they are listed for heat pump installation. They may well do other work, but heat pump 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 Diarmuid Walsh Plumbing and Heating.
The Other Trades a Galway 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 Galway on our sister sites, each one worth lining up before the heating work starts rather than after.
- Alongside the installation Plumbers and gas installers in Galway Taking out an old oil or gas boiler, reworking the heating circuit and fitting the hot water cylinder is usually done by a registered plumber, and a heat pump is usually commissioned by a qualified, registered professional.

SEAI Heat Pump Grant for Work by Diarmuid Walsh Plumbing and Heating
SEAI support for a heat pump is up to €12,500 (as of July 2026) for eligible homes. Ask Diarmuid Walsh Plumbing and Heating 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.
