If you’ve ever stood beside a window on a cold morning in Ireland and felt a draught that shouldn’t be there, you’re not alone. Most older homes across Dublin – especially in places like Lucan, Clondalkin, Blanchardstown, Tallaght, and beyond – still have windows and doors that are well past their best.
The good news? The Government has just announced new grants that can put up to €5,600 back in your pocket for upgrading your windows and doors. And this time, the grants are much more accessible for everyday homeowners, not just people doing full-scale renovations.
So let’s break it all down in plain English. No jargon. No waffle. Just what the grants are, how much you can get, and whether it’s actually worth doing.
What’s Been Announced?
As part of Budget 2026, a record €558 million has been allocated to retrofitting and insulation grants across Ireland. That’s the biggest pot of money we’ve ever seen for home energy upgrades.
Within that, there’s a strong focus on windows and doors – because, quite simply, there’s no point pumping heat into a house if it’s leaking straight back out again.
The new grants are designed to help homeowners replace old, inefficient windows and doors with modern, energy-efficient alternatives that actually keep the heat in.
How Much Can You Get? (This Is the Bit Everyone Asks)
The amount you can claim depends on the type of property you live in. Here’s the breakdown:
- Detached houses: Up to €4,000 for upgrading windows
- Semi-detached & end-of-terrace homes: Up to €3,000
- Mid-terrace houses: Up to €1,800
- Apartments & duplexes: Up to €1,500
On top of that, there are also door grants:
- €800 per door
- Up to a maximum of two doors (€1,600 total)
That’s how homeowners can reach figures of €5,600 in total support when upgrading both windows and doors.
Why Windows & Doors Are Finally Getting the Attention They Deserve
For years, windows and doors were kind of the forgotten part of retrofitting. Insulation and heat pumps grabbed all the headlines.
But anyone who’s lived in an older Dublin house knows the truth: if your windows are rattling and your front door lets in a breeze, your heating bills are fighting a losing battle.
Modern uPVC windows and composite doors:
- Keep heat inside your home where it belongs
- Reduce draughts and cold spots
- Cut down on outside noise (huge bonus if you’re near a main road)
- Improve your BER rating
- Make your home feel more comfortable overall
And now, with these grants in place, it finally makes financial sense to tackle them.
Is This Only for Full Renovations?
No – and this is a big deal.
One of the best things about these new grants is that you don’t need to be doing a full house retrofit. You can upgrade your windows and doors as a standalone project.
That means:
- You don’t have to rip the house apart
- You don’t need to install a heat pump
- You can take things step by step
For many homeowners, especially families living in the house full-time, that flexibility is a game-changer.
Why uPVC Windows & Composite Doors Are So Popular Right Now
We get asked this all the time: “Are uPVC windows still the best option?”
Short answer: yes, for most homes in Dublin.
Modern uPVC windows:
- Are highly energy-efficient
- Require very little maintenance
- Don’t rot, warp, or need repainting
- Come in styles that suit both older and newer homes
Composite doors are another big favourite. They look solid, feel secure, and perform far better than older timber or hollow doors.

How This Fits Into Bigger Energy Upgrades
Replacing windows and doors is often the first step people take before moving on to bigger energy upgrades.
It makes sense. There’s no point insulating walls or upgrading heating systems if your home is still losing heat through old glazing.
If you’re thinking long-term, windows and doors work really well alongside:
- Attic insulation
- External or internal wall insulation
- General home energy improvements
You can explore those options on our Energy Upgrades Dublin page.
Is Now a Good Time to Do It?
Honestly? Yes.
Between rising energy costs, improved grant levels, and better product options than ever before, this is one of the best times we’ve seen to upgrade windows and doors.
Many homeowners put this kind of work on the long finger because it feels like a “big spend”. The grants take a lot of that pressure away.
And once it’s done, the difference is immediate. Warmer rooms. Quieter spaces. Less fiddling with the heating.
Talk to Someone Who Actually Knows the Job
Grants are great, but getting the installation right matters just as much.

Frequently Asked Questions
Do I need to apply for the grant before starting work?
Yes. Grant approval must be in place before any work begins, otherwise the claim won’t be valid.
Can I replace just some windows?
In many cases, yes. However, grant amounts are capped based on property type, so it’s best to plan the work carefully.
Are doors included in the same grant?
Doors are covered separately at €800 per door, up to a maximum of two doors.
Do I need to move out during installation?
No. Window and door replacements are usually completed with minimal disruption.
Will this improve my BER rating?
In most cases, yes. Modern windows and doors significantly reduce heat loss.
Is this only for older homes?
Older homes benefit the most, but eligibility depends on current efficiency levels and grant criteria.
Final Thoughts
If your home feels colder than it should, your heating bills are climbing, or your windows and doors have seen better days, these new grants are worth a serious look.
You don’t have to do everything at once. Even upgrading windows and doors alone can make a noticeable difference.
