SEAI Grants for Heat Pumps in Ireland: The Complete 2026 Guide

If you are considering upgrading your home heating system, a heat pump is one of the most energy-efficient options available to Irish homeowners. Better still, the Sustainable Energy Authority of Ireland (SEAI) offers generous grants that can significantly reduce the upfront cost. In this guide, we break down everything you need to know about SEAI heat pump grants in 2026.

How Much Is the SEAI Heat Pump Grant in 2026?

As of 2026, the SEAI provides a grant of up to €6,500 towards the cost of installing an air-to-water heat pump in your home. This applies to both existing homes (built before 2021) and certain retrofit scenarios. The grant covers a significant portion of the total installation cost, which typically ranges from €8,000 to €14,000 depending on the size of your home and the system selected.

For ground-source (geothermal) heat pumps, the grant can be higher due to the greater installation complexity. Air-to-air systems, which function more like reversible air conditioning units, attract a lower grant as they do not provide hot water.

Who Is Eligible for the Grant?

To qualify for the SEAI heat pump grant, your home must meet several criteria:

• The property must have been built and occupied before 2021.
• You must use an SEAI-registered contractor (such as Riverside Plumbing & Heating) for the installation.
• The home should ideally have a BER rating of B2 or better after the heat pump is installed. If not, additional insulation works may be required first.
• The heat pump system must meet SEAI technical specifications and be on the approved product list.
• The grant must be approved before any work begins.

The Application Process Step by Step

Applying for the SEAI grant is straightforward, especially when you work with a registered contractor who handles much of the paperwork. Here is the typical process:

1. Get a BER assessment - A BER assessor surveys your home to determine its current energy rating and identify what upgrades are needed.
2. Choose your contractor - Select an SEAI-registered installer. At Riverside Plumbing & Heating, we are fully registered and handle the application on your behalf.
3. Submit your application - Your contractor submits the grant application through the SEAI portal. You will receive confirmation within a few weeks.
4. Installation - Once approved, the heat pump is installed. This usually takes two to three days for a typical three-bedroom home.
5. Claim your grant - After installation, the paperwork is submitted and the grant is paid directly to you or deducted from your invoice.

Which Type of Heat Pump Is Right for Your Home?

The most common type installed in Irish homes is the air-to-water heat pump. It extracts heat from the outside air (even in cold weather) and uses it to heat your radiators, underfloor heating, and hot water cylinder. Air-to-water systems work best with underfloor heating or oversized radiators, and they pair brilliantly with well-insulated homes.

Ground-source heat pumps are more efficient but cost significantly more to install because they require bore holes or ground loops. They are best suited to larger rural properties with sufficient garden space.

What Are the Running Costs?

Heat pumps are dramatically cheaper to run than oil or gas boilers. A well-installed air-to-water system can deliver three to four units of heat for every one unit of electricity consumed. For an average Irish home, this translates to annual heating bills of around €800 to €1,200, compared to €1,800 to €2,500 for oil.

When combined with the SEAI grant, the payback period for a heat pump is typically five to seven years, after which you are essentially saving money every year while reducing your carbon footprint.
