Front Door 4 U is on the SEAI Registered Contractor list (ID 19913) for the Windows and Doors grant. You can verify any installer through the official SEAI page.
There are a handful of technical thresholds your project has to clear. Every Martom door we install is specified to meet them. If you are getting quotes from other installers, ask these questions before you sign anything.
Post works HLI of 2.3 or lower. This is the headline SEAI requirement. After the works, your Heat Loss Indicator needs to be 2.3 or below. In reality, your HLI is mostly driven by your existing wall and attic insulation, not the new windows. So if you are starting from poor insulation, new windows on their own probably will not get you across the line. A pre works BER tells you where you stand before you spend money.
U value. U value measures how much heat passes through a window or door. Lower is better. SEAI's technical specification calls for high performance units, typically 1.4 W/m²K or better for windows. Plenty of "energy efficient" products on the market do not actually meet it. Ask for the U value in writing on every quote you receive.
Glazing type. SEAI's spec generally calls for triple glazing on north facing windows (they get the least sun and lose the most heat) and high performance double or triple glazing elsewhere. A registered contractor will spec this correctly for your house orientation.
Adequate ventilation after install. This one catches almost everyone. Old, draughty windows and doors are ventilating your home without you knowing it. Replace them with airtight modern units and you can run into condensation and indoor air quality issues if you do not put proper ventilation in. We assess this on the home survey and factor it into the quote.
There are two routes. You can apply yourself (DIY) or use a One Stop Shop service.
A One Stop Shop is an SEAI approved provider that takes the whole project off your hands. They apply for the grant on your behalf, manage the works, and the grant gets deducted upfront from what you pay them. Useful if you are combining three or more measures (say insulation plus windows plus a heat pump). Overkill if you only want windows and doors.
For most window and door projects, the DIY route is faster and simpler. Here is what it looks like.
Here is a project profile from our recent work. Names anonymised, spec is real.
The home: Three bedroom semi detached in Dublin, built 1998. Walls and attic insulation rated "Good" on a 2024 BER. BER rating C2.
The project: Replace the front door and back door. Both were 1998 originals with single glazed panels and a noticeable draught. We fitted two Martom hybrid doors, both specified to meet the SEAI U value threshold.
The grant:
If the same family had also replaced their windows in the same project, the grant would have stacked. €1,600 on doors plus €3,000 on windows on a semi detached comes to €4,600 off the total.
If your home was built after 2011, or your insulation is not yet up to scratch, or you cannot manage the upfront cost, there are other routes worth knowing.
The Warmer Homes Scheme is a fully funded SEAI upgrade for homeowners who get certain welfare payments, most commonly the Fuel Allowance. It can include attic insulation, wall insulation, draught proofing, and sometimes windows. Doors are not a standard Warmer Homes measure, but draught proofing the existing doors is. Current waiting time is up to 24 months.
Housing Aid for Older People is a separate scheme run by local councils (not SEAI) that can cover doors and windows for homeowners over 66 in certain circumstances. Talk to your county council to apply.
0% VAT on certain energy efficient products can reduce the cost of grant eligible windows and doors. The installer applies it at point of sale where it qualifies.
We have been installing external doors across Ireland since 2015. We registered with SEAI for the Windows and Doors grant as soon as the scheme opened in 2026 (ID 19913), and we now do grant eligible installs nationwide.
Our doors come from Martom, a Polish manufacturer who has been making external doors since 1999. Hybrid construction (wood and steel core, optional aluminium thermal frame). Every Martom door we install is specified to meet the SEAI U value threshold. We handle the technical declaration that goes with your grant claim, and we will walk you through the SEAI portal if it is your first time using it.
"The lads did great job! We got new doors installed by them and the doors are very high quality and the service from start to finish is 5 stars! Highly recommended!" Aidas Boss
"Fair price, detailed breakdown of what you're paying for and to finish it off, top level service. Just had lads to fit the door today and they did brilliant job. Kept the house very clean while doing the work and I cannot recommend them high enough." Tomislav Džanak

Yes, but only retrospectively to 27 January 2026. The installer has to be on the SEAI registered list and the products have to meet spec. Anything done before 27 January 2026 is not covered.
The grant covers replacement of existing windows and doors in homes built and occupied before 2011, including extensions built before 1 January 2011. Extensions built after that date, and new builds, are not eligible.
No. SEAI only offers a once off grant for windows. Whatever you claim for in your first application is your one shot, so plan carefully. Same for doors. The €1,600 cap is a one time entitlement per home.
Yes. You can apply for windows only, doors only, or both. The values stack up to the combined max for your property type.
HLI is your Heat Loss Indicator. It measures how easily heat escapes from your home. SEAI requires an HLI of 2.3 or lower (lower is better) before they will pay out on the windows and doors grant. Your BER advisory report has it. If you do not have a recent BER, you will need one before applying.
No. Unlike the Warmer Homes Scheme, the standalone grant is open to any homeowner whose house meets the eligibility criteria, regardless of income.
0% VAT applies to certain energy efficient products that meet specific criteria. Your installer will confirm whether your products qualify. We apply 0% VAT to grant eligible Martom doors where it applies.
For a door only project, typically six to ten weeks from quote acceptance to the grant landing in your account. For a full set of windows, twelve to twenty weeks because manufacture takes longer. The grant payment itself usually arrives four to eight weeks after you submit the claim.
Yes. This is the single most common reason claims get refused. If your installer is not on the SEAI list, the application will not be accepted, even if the products and the install are spot on. Front Door 4 U is registered (ID 19913).
SEAI's technical specification calls for high performance units, typically 1.4 W/m²K or better. Lower is better. Every Martom door we install for grant projects is specified to meet the SEAI requirement.
Yes, two of them. A pre works BER is strongly advised so you know whether your home meets the HLI threshold before you spend money on works. A post works BER is required by SEAI as part of the claim, and is part funded by a separate SEAI grant.
