How the €12,500 Grant Is Structured

The Heat Pump System Grant is a bundle of three separate fixed-value grants: €6,500 for the heat pump unit itself, €2,000 for central heating distribution upgrades (radiators, pipework), and a €4,000 Renewable Heat Bonus paid after 12 months of verified operation when replacing a fossil-fuel or electric heating system. For system types, costs, and sizing, see the full heat pump installation guide.

The grant increased from €6,500 to €12,500 on 3 February 2026, the largest single increase in the scheme’s history. All open applications received the increased value automatically.

ComponentAmountWhen Paid
Heat pump unit€6,500On completion, with other components
Central heating distribution upgrade€2,000On completion
Renewable Heat Bonus€4,00012 months after verified operation
Total maximum€12,500

Apartments are capped at €9,500. Air-to-air heat pumps qualify for a different structure: up to €7,500 (€3,500 unit plus the €4,000 Renewable Heat Bonus, with no heating distribution component since air-to-air doesn’t use radiators).

Eligibility Requirements

  • Property must have an MPRN (electricity meter reference)
  • Home must have been built and occupied before 2021
  • Home must meet a minimum fabric standard: Heat Loss Indicator of 2.3 or better, or attic and wall insulation rated “Good” or “Very Good”
  • Existing fossil fuel boiler must be removed to qualify for the full Renewable Heat Bonus
  • Heat pump must be on SEAI’s approved product list
  • Installation must be by an SEAI-registered heat pump installer

The Application Process

From BER assessment to the Renewable Heat Bonus landing 12 months later.

Before applying

Get a BER Assessment

Confirms whether your home meets the fabric standard for approval. Cost €150–€300, partially offset by the separate €50 BER grant.

Before applying

Choose a Registered Installer

RetrofitIreland.ie connects homeowners with SEAI-registered heat pump installers across all 26 counties.

Day 1

Apply Online at hes.seai.ie

Before any work starts. You’ll need your MPRN, PPS number, and BER certificate number.

Minutes later

Receive Your Letter of Offer

Heat pump applications are typically approved within minutes. Valid for 8 months. Do not start work before receiving it.

8–12 weeks

Installation (Current Lead Times)

Heat pump installers are the busiest trade right now due to demand from the grant increase. Book early.

Before installer finishes

Book the Post-Works BER Assessor

A delayed BER assessment is one of the most common holdups in the payment process. Book early.

4–6 weeks

Payment Processed

After correct documentation (Declaration of Works, Request for Payment, post-works BER) is submitted.

12 months later

Renewable Heat Bonus Released

SEAI verifies correct operation and releases the final €4,000 component.

What Causes Rejection or Delay

Starting work before the Letter of Offer disqualifies the entire grant. This is the single most common reason applications fail, and there are no exceptions.

Cannot Combine With the Heating Controls Grant

The heat pump bundle already includes the €2,000 heating distribution upgrade component, so the separate €700 heating controls grant cannot be claimed on the same application.

Keeping the Old Boiler Forfeits the Renewable Heat Bonus

The existing fossil fuel system must generally be removed to qualify for the full €4,000 component.

Contractor Registration Mismatches

A contractor registered for insulation work cannot process a heat pump grant. The installer must be specifically registered for heat pump installation.

Changing Details Without Updating SEAI

Any change from what’s stated on the Letter of Offer, contractor, system size, or upgrade type, must be communicated to SEAI before proceeding, or payment will be held.

Random inspection adds time. SEAI inspects a percentage of completed works, which can add 2 to 4 weeks and isn’t something you can control or predict.

Timing Your Application

Apply Early

With 8–12 week installer lead times, get your Letter of Offer as soon as you have a survey and quote, so you don’t lose time within the 8-month window.

Sequence Fabric-First

Insulation before the heat pump is generally recommended, since it affects whether your home meets the Heat Loss Indicator threshold.

Self-Managed vs One Stop Shop

Applying directly means managing the paperwork yourself, though installers often assist. OSS handles the whole application, grant deducted upfront.

Heat Pump Grant Questions

Heat pump applications are typically approved within minutes when submitted correctly with a registered installer’s details.
The Letter of Offer is valid for 8 months. If the works aren’t completed and documentation submitted within that window, the offer expires and you’d need to reapply.
No. The heat pump grant bundle already includes a €2,000 heating distribution upgrade component, so the separate €700 heating controls grant cannot be claimed on the same application.
Common causes include a delayed post-works BER assessment, the property being selected for random SEAI inspection, or a mismatch between what’s on the Letter of Offer and what was actually installed. Booking your BER assessor before the installer finishes the job avoids the most common cause.
Keeping the old fossil fuel boiler forfeits the €4,000 Renewable Heat Bonus. The existing system generally needs to be removed to qualify for the full grant.
If you don’t already have one, yes. It confirms whether your home meets the fabric standard required (Heat Loss Indicator of 2.3 or better) and identifies whether insulation work is needed first. See our BER guide for the full detail.
