How to Apply for SEAI Grants

The correct process depends on your route. Individual Grants, One Stop Shop, and Warmer Homes each work differently — follow the steps for your route.

The most common — and costly — mistake

You can contact contractors, get quotes, and choose a SEAI-registered installer before applying — that part is fine and is often required to nominate a contractor on the application. What you cannot do is let any actual works begin before SEAI written approval. Individual Grants and One Stop Shop: get quotes freely, but works must not start before written SEAI approval. Warmer Homes is different — you must not arrange or pay for any works yourself at all; SEAI manages everything. There are no exceptions and no appeals process for works started early.

Individual Grants

Better Energy Homes

Suits: Most homeowners doing 1–3 specific upgrades

Who applies: You apply directly to SEAI — the homeowner manages the process

1

Check your likely route

Same day

Before doing anything, work out which SEAI route fits your home — Individual Grants, One Stop Shop, or Warmer Homes. This shapes everything that follows: who applies, what assessments you need, and which contractors are appropriate. Run the navigator if you’re unsure.

  • Run the HomeUpgrade.ie navigator for an indicative route
  • Check the SEAI overview pages for each scheme
  • Confirm whether your home meets basic criteria (year built, BER band, ownership)
Run the navigator
2

Get a BER or technical assessment if needed

1–2 weeks

A BER or technical assessment may be needed depending on the route and the upgrade type. For example, a heat pump usually needs a technical assessment; a Windows & Doors application requires evidence of insulation conditions. You may also already have a recent BER. Confirm what your specific route requires before you apply — don’t assume a BER is mandatory for every grant.

  • Check what assessment your specific upgrade requires (heat pump, windows, OSS, etc.)
  • Find a registered BER assessor or technical assessor if needed
  • Receive your assessment report — this can also help you choose the right contractor

Get quotes from SEAI-registered contractors

1–2 weeks

You can talk to contractors and get written quotes BEFORE you apply for a grant — there is no SEAI rule against this. The rule is that the works themselves must not start until SEAI gives written approval. Using a SEAI-registered contractor for the specific measure is mandatory; any work done by an unregistered contractor cannot be grant-funded.

  • Use SEAI's contractor register (hes.seai.ie) to shortlist registered installers
  • Request 2–3 written quotes specifying the proposed work
  • Verify each contractor's SEAI registration number for the relevant measure
  • Make clear up front that no work will start until SEAI approval is in place

4

Choose your contractor

Same week

For many individual grants, SEAI requires you to nominate a chosen contractor as part of your application. Pick the contractor whose quote, registration, and availability best fit your project — but do not authorise any work to begin yet.

  • Pick a SEAI-registered contractor for the specific measure
  • Confirm in writing that no works will begin before SEAI approval
  • Avoid paying any large deposit before approval is in place
5

Apply to SEAI BEFORE works start

2–4 weeks for approval

Submit your grant application online through the SEAI portal. Most individual grant applications include your nominated contractor. The critical rule is that no works may begin until SEAI has issued written approval. Starting work before approval permanently disqualifies that measure.

Critical: Do NOT let any work begin before receiving written approval from SEAI. Getting quotes is fine; starting works is not.

  • Apply online through hes.seai.ie
  • Upload required documents (proof of ownership, MPRN, PPS number, BER if required)
  • Confirm your nominated contractor on the application
Apply on hes.seai.ie
6

Wait for written SEAI approval

Typically 2–4 weeks

SEAI reviews your application and either approves, requests more information, or declines. Keep the written approval letter — your contractor and the SEAI completion process both rely on it.

  • Watch for SEAI correspondence (email + portal)
  • Respond promptly if SEAI requests further information
  • Save the written approval letter — you will need it for completion
7

Works begin

Varies by upgrade

Once SEAI written approval is in place, your chosen contractor can carry out the works. Typical durations: attic insulation (1 day), cavity wall insulation (1–2 days), external wall insulation (1–2 weeks), heat pump installation (3–5 days), solar PV (1–2 days).

  • Ensure works match the approved scope — do not agree to scope changes without notifying SEAI
  • Take photos during and after completion
  • Do not sign off until you are satisfied with the work
8

Completion documents, post-works BER (if required), and payment

4–8 weeks after completion

Your contractor submits a Completion Report to SEAI. Some routes (e.g. heat pump, OSS) require a post-works BER assessment to confirm the energy improvement before the grant is paid. Payment depends on the scheme — usually paid to the applicant, sometimes directly to the contractor.

  • Contractor submits the completion report to SEAI
  • Book a post-works BER assessment if your route requires one
  • SEAI reviews the documentation and issues grant payment
  • Keep all records for at least 3 years in case of audit

One Stop Shop

Deep Retrofit

Suits: Homes planning multiple major upgrades and targeting B2 BER or better

Who applies: A SEAI-registered One Stop Shop provider manages the assessment, application, works and grant claim — you choose the provider

1

Select a SEAI-Registered One Stop Shop Provider

1–2 weeks

Contact one or more registered One Stop Shop providers. They will explain their process and costs. Always verify current SEAI registration before signing any agreement.

  • Review SEAI's official list of registered One Stop Shop providers at seai.ie
  • Contact 2–3 providers for initial consultations
  • Ask for a breakdown of their management fees and scope of service
SEAI One Stop Shop list
2

Technical Assessment of Your Home

1–2 weeks

The One Stop Shop provider arranges a technical assessment of your home. This determines the upgrade scope, confirms BER improvement potential, and forms the basis for the grant application. You cannot specify or change the works in advance.

  • Allow assessor access to assess walls, roof, heating system, and windows
  • Receive a proposed scope of works from the provider
  • Discuss options if you have preferences or constraints
3

Provider Submits Application to SEAI

2–4 weeks for approval

The One Stop Shop provider submits the grant application on your behalf. You do not apply directly to SEAI under this route. Do NOT start any work until the provider confirms SEAI approval.

Do NOT start any work before your provider confirms SEAI grant approval. This applies under the One Stop Shop route just as much as Individual Grants.

  • Review and sign the application documentation your provider prepares
  • Do NOT arrange any work yourself — the provider manages this entirely
  • Wait for your provider to confirm written SEAI approval
4

Works Are Carried Out

Varies — weeks to months for full retrofit

The provider appoints and manages SEAI-registered contractors. You do not need to source or manage contractors yourself. A full home retrofit typically takes several weeks.

  • Works are managed and coordinated by your One Stop Shop provider
  • Confirm the scope and timeline with your provider before works begin
  • Keep records and raise any concerns directly with the provider
5

Post-Works BER and Completion

1–2 weeks after completion

After works are complete, a post-works BER assessment confirms the energy improvement. You must reach a minimum B2 BER rating for the grant to be paid. The provider manages this process.

  • Provider arranges post-works BER assessment
  • Confirm B2 BER or better has been achieved
  • Provider submits completion report to SEAI
6

Grant Applied and Costs Settled

4–8 weeks after completion

Under the One Stop Shop route, the grant is applied as a reduction to your project cost by the provider — you pay the net amount rather than the full cost. SEAI pays the provider directly.

  • Review final project cost statement from your provider
  • Grant value is applied as a deduction — you pay the net amount
  • Keep all documentation for at least 3 years

Warmer Homes Scheme

Fully Funded

Suits: Qualifying social welfare recipients in homes built before 2006 with BER C or lower

Who applies: You apply to SEAI, then SEAI manages everything — including appointing and paying the contractor

1

Wait — Current List is Approximately 24–26 Months

24–26 months (current estimate)

SEAI will contact you when you reach the top of the waiting list. You cannot expedite this process. While waiting, do not arrange any energy upgrade works yourself — doing so may affect your eligibility.

  • Keep your contact details up to date with SEAI
  • Do NOT arrange any works yourself while waiting
  • Your eligibility will be re-confirmed closer to the time of works
4

SEAI Technical Assessment

When you reach the top of the list

SEAI contacts you and arranges a technical assessment of your home. This determines what works are needed and will be carried out. You cannot choose or specify the scope of works in advance — SEAI and their appointed contractor decide based on the home's condition.

  • Allow SEAI assessor access to your home
  • Receive details of the proposed works from SEAI
  • Confirm your availability for the works
5

Works Carried Out at No Cost to You

Determined by SEAI

SEAI appoints a registered contractor and manages all works on your behalf. You do not pay anything. Typical works may include attic insulation, wall insulation, heating controls, and in some cases windows.

  • Allow contractor access to carry out approved works
  • SEAI pays the contractor directly — no cost to you
  • Contractor completes works and SEAI signs off on completion

Frequently Asked Questions

Can I combine Better Energy Homes grants with the One Stop Shop?

No — you cannot use Better Energy Homes grants for the same measures covered by a One Stop Shop grant. You must choose one route per measure. Individual grants and OSS can be used for different works at the same property.

Can a landlord apply for grants?

Landlords can apply for most Better Energy Homes individual grants. The Warmer Homes Scheme is for owner-occupiers only. The new Windows & Doors grant (March 2026) is also open to landlords and owner management companies.

What documents do I need to apply (Individual Grants route)?

You'll typically need: PPS number, MPRN (from your electricity bill), and proof of property ownership (or landlord consent for rental). A BER or technical assessment may be required depending on the specific upgrade and route — for example, heat pump applications usually need a technical assessment, and Windows & Doors require evidence of insulation conditions. Don't assume a BER is needed for every grant; check the requirement for your specific measure.

What if my home is a new build?

Homes built in 2011 or later are not eligible for most Better Energy Homes grants. They may qualify for the Solar PV scheme. One Stop Shop and Warmer Homes also require homes to have been built before 2011.

How long does the full process take?

Individual Grants: typically 3–6 months from application to payment. One Stop Shop: 6–12+ months depending on project size. Warmer Homes: approximately 24–26 months on the waiting list before works begin.
