You may be eligible for SEAI grants. The Sustainable Energy Authority of Ireland (SEAI) offers substantial financial grants to homeowners in County Donegal.


Peace of mind guaranteed

Fast relief for urgent issues
Upgrading your home to a modern, renewable heating system is a significant investment that pays dividends in comfort & reduced energy bills. To support this transition, the Sustainable Energy Authority of Ireland (SEAI) offers substantial financial grants to homeowners in Letterkenny & throughout County Donegal. As a fully registered SEAI contractor, McGahern Heating & Plumbing is qualified to install grant-aided systems, ensuring your project meets the rigorous technical standards required to secure your funding.
The Individual Energy Upgrade Grant route allows you to choose specific energy improvements that suit your budget & your home’s requirements. We specialise in the following grant-aided services:
Substantial grants are available to help replace old oil or gas boilers with high-efficiency heat pumps. This is the most effective way to future-proof your home & eliminate fossil fuel dependency.
If you are not yet ready for a full heat pump installation, you can secure funding to install modern, zoned heating controls. This allows you to heat specific areas of your home only when needed, significantly reducing wasted energy.
Before installing a heat pump, a technical assessment is required to ensure your home is “Heat Pump Ready” (meeting the required Heat Loss Indicator). We can guide you through this essential first step.
We aim to make the application process as straightforward as possible for our Donegal clients.
With many years of specialised experience in the heating and plumbing industry, we are a trusted Irish company.
