How to Qualify for the SEAI Heat Pump Grant in 2026

The SEAI heat pump grant changed significantly in 2026. The maximum support for a qualifying heat pump system can now reach €12,500, depending on the dwelling and system.

But the headline figure does not apply automatically to every home. The grant is a bundle of separate supports, and your home's construction, heating system and technical suitability matter.

How much is the heat pump grant?

For the common air-to-water heat pump route, the current maximum package is:

That gives a maximum of €12,500 for detached, semi-detached/end-of-terrace and mid-terrace homes for the applicable systems.

For apartments, the maximum for air-to-water and other water-based systems is currently €9,500.

Air-to-air heat pump systems have a separate maximum of €7,500.

Who can apply?

SEAI's current individual heat-pump grant guidance lists:

The property must have an MPRN and must have been built and occupied before 2021.

The most important issue: heat loss

A heat pump does not work like a traditional boiler.

Instead of generating heat by burning fuel, it moves heat from outside into the home. The efficiency of the system depends heavily on the home's heat demand and the design of the heating system.

SEAI therefore places specific emphasis on heat loss.

Your home needs to meet the scheme's heat-loss requirements.

Do I need a technical assessment?

It depends on the age and BER information for the home.

For homes built before 2007, a technical assessment is required if you do not have a valid BER assessment or if your BER indicates a high heat loss.

You do not need the technical assessment where your valid BER shows a Heat Loss Indicator of 2.3 W/(K.m²) or less.

For homes built from 2007 onwards, a technical assessment is generally not required because the dwelling is likely to meet the required heat-loss level, although the homeowner can still choose to have one.

A €200 grant is available for the technical assessment when it is connected with a heat pump application.

What is the self-declaration route?

For eligible homes, the self-declaration route can confirm that the property meets the heat-loss requirements without a technical assessment.

SEAI says you can qualify for this where:

Why insulation matters

A heat pump can be an excellent upgrade, but it should not be treated as a magic fix for a leaky building.

Before choosing a system, look at:

The better the building fabric, the easier it is to design a low-temperature heating system that can provide comfortable heat efficiently.

What is the Renewable Heat Bonus?

The €4,000 Renewable Heat Bonus is designed to support homeowners replacing certain existing heating systems with a heat pump.

SEAI currently identifies qualifying replacement of:

The bonus is subject to the scheme's detailed eligibility rules.

What are the central-heating upgrade costs?

A heat pump may require changes to the heat-distribution system.

The current grant package can provide up to €2,000 towards required upgrades to central-heating components, such as:

This does not mean every installation automatically receives €2,000. The amount depends on the eligible work and the scheme rules.

How to apply

Step 1: Assess the home

Start with your home's age, BER, insulation and heating system.

Step 2: Establish heat-loss suitability

Determine whether you need a technical assessment or can use the self-declaration route.

Step 3: Choose an SEAI registered contractor

Get more than one quotation and ask each contractor to explain:

Step 4: Apply for the grant

You must have grant approval before starting the work.

Step 5: Complete the installation

SEAI currently gives eight months from the grant offer to draw down the grant.

Step 6: Complete the post-works BER

A post-works BER is required for the grant drawdown process, with a €50 BER grant available.

Step 7: Submit the evidence

For heat pump installations, SEAI lists documents including the Declaration of Works, Request for Payment, and relevant technical/design documentation.

Is a heat pump right for every Irish home?

No.

The grant makes the economics more attractive, but suitability still depends on the building.

A home can be a poor candidate if it has:

This is why the technical assessment and system design matter.

A heat-pump quote checklist

Do not compare heat pumps only by the manufacturer's headline output.

Ask each installer for:

Common mistakes

Buying the biggest heat pump

Oversizing can be as problematic as undersizing. The system should be designed around the building's actual heat demand.

Ignoring insulation

If fabric improvements are needed, consider completing them before finalising the heating-system design.

Assuming €12,500 is guaranteed

€12,500 is a maximum combined support figure for qualifying circumstances and systems, not a universal payment.

Starting before grant approval

Grant approval must be in place before the eligible works begin.
