Upgrading your windows and doors is one of the most effective ways to improve your home’s energy efficiency and reduce heating costs. Although there are no specific SEAI grants solely for windows and doors, Irish homeowners can benefit from a number of broader home retrofit schemes that include these essential upgrades.

This guide explains the available SEAI grants for window and door replacements in 2025, the benefits of making these energy-efficient upgrades, and what homeowners need to know when applying for grants.

Why Upgrade Your Windows and Doors?

Old, inefficient windows and doors can result in significant heat loss, which drives up energy bills and leaves your home feeling cold and drafty. Replacing them with modern, energy-efficient options can make your home more comfortable and lower your heating costs. According to SEAI, upgrading to double or triple-glazed windows can reduce your energy bills by up to €100 to €400 per year, depending on the type of window and your home’s insulation levels.

In addition to saving on energy costs, upgrading your windows and doors can also help your home meet SEAI’s Building Energy Rating (BER) standards, which are key to qualifying for grants under various home energy schemes.

SEAI Grant Schemes for Window and Door Upgrades in 2025

While there are no direct SEAI grants specifically for windows and doors, homeowners can receive funding for these upgrades as part of larger energy retrofitting programs. Here are the three main SEAI schemes that include support for window and door replacements:

1. The National Home Energy Upgrade Scheme (One-Stop Shop Scheme)
2. Better Energy Warmer Homes Scheme
3. Energy Efficiency Obligation Scheme (EEOS)


1. The National Home Energy Upgrade Scheme (One-Stop Shop Scheme)

The National Home Energy Upgrade Scheme, also known as the One-Stop Shop Scheme, is designed to help homeowners improve the overall energy efficiency of their homes. This scheme provides grants for multiple upgrades, including windows and doors, and aims to bring homes to a minimum BER rating of B2.


Grant Amounts for Windows and Doors:
Windows:
Apartment: €1,500
Mid-terrace house: €1,800
Semi-detached/end of terrace house: €3,000
Detached house: €4,000


Doors: €800 towards the installation of two external doors

Key Requirements:

2. Better Energy Warmer Homes Scheme

This scheme is specifically designed for homeowners who are considered vulnerable or who receive qualifying social welfare payments. It offers fully funded energy efficiency upgrades, including window and door replacements, to improve the living conditions of homes that are often the least energy efficient.

Eligibility Criteria:

3. Energy Efficiency Obligation Scheme (EEOS)

The EEOS requires large energy suppliers to support homeowners in completing energy efficiency projects, including replacing windows and doors. Under this scheme, you can apply to your energy provider for assistance with energy-efficient upgrades.

Who Can Apply?

Homeowners can reach out to their current energy supplier to check if they offer support under the EEOS. Major energy suppliers such as Bord Gáis, Electric Ireland, Energia, and SSE Airtricity are obligated to provide help under this scheme. If your provider doesn’t offer assistance, you can apply to another obligated party for support.

How to Apply for SEAI Grants

Christmas really is the most magical time of the year.

With so many of us putting up our trees by December 1st this year, you might be wondering what else can add a little extra Christmas cheer to your home.

Don’t forget the festive potential of decorating your windows and doors—they’re perfect for spreading holiday magic beyond just the tree and fireplace!

Read on for top ideas to bring Christmas charm to your windows and doors.

Take wreath inspiration from the US 

As you welcome more guests into your home this Christmas season, you’ll want to make a memorable first impression. While a wreath on the front door is a classic touch, why not take it a step further?

In the US, it’s popular to add wreaths to both windows and doors—The Irish are also known for their love of grand holiday decor, and Christmas is no exception.

Placing matching wreaths with red bows on each window creates a beautiful, coordinated look that shines from both inside and outside your home.

Add twinkling lights

Embrace the festive spirit by filling your home with all kinds of glowing lights.

Drape fairy lights, place lanterns, and arrange candles around your doors and windows. Lighting an advent candle each night can also become a fun, heartwarming tradition.

Decorating windows and doors with lights is an affordable way to bring the cozy warmth of the season into your home.

Add ornaments to windowsills

You’ve likely gathered a variety of festive knick-knacks, snow globes, and Christmas ornaments over the years.

From a handmade Father Christmas crafted by your children to a classic Nativity scene, adorning your windowsills with these decorations is always a great idea.

For an elegant touch, consider adding poinsettias to your windowsills. These beautiful plants are a symbol of Christmas and will brighten up your space beautifully.

The cold weather and longer nights make us spend more time indoors than in other seasons, so it’s essential to keep your home warm and comfortable.

Windows play a key role in keeping out the elements and creating a cozy atmosphere indoors. It’s important to inspect them carefully, as they could be letting in drafts and driving up heating costs.

Learn how to check if your windows are ready for winter or in need of replacement, explore options for window coverings, and get tips on choosing the right replacements.

Observe if they have gaps

Over time, small gaps can develop in older window frames, and even the tiniest opening allows cold air to seep in.

To check for drafts, run your hand along the edges of your windows to feel for cold spots, and carefully inspect the frames and seals for any gaps or cracks. You can also try the candle test: light a candle, hold it near the frames, and if the flame flickers, you’ve likely found a draft.

If you prefer to keep your existing windows, seal any gaps or cracks with caulking or draft excluders to keep the cold air outside.

Install window coverings

In addition to enhancing the look of your windows and improving light and privacy control, insulated window coverings help reduce heat loss and block cold drafts.

Thick thermal curtains are particularly effective at trapping heat from your heating system and blocking drafts. Cellular shades, with their honeycomb structure, are also excellent at insulating by trapping air. For added warmth, you can apply window film to further insulate less efficient windows.

Upgrade to energy efficient windows

If air leaks are severe, simply sealing windows or adding treatments will have limited effect. However, Sean Doyle’s energy-efficient UPVC or Aluminium windows could make a noticeable difference.

While upgrading windows requires a higher initial investment than sealing or adding coverings, the long-term benefits—in both comfort and savings—are far greater.

Sean Doyle’s window collections exceed standard energy ratings, thanks to their highly insulating frames and low-emissivity glazing, ensuring lasting warmth and efficiency.


Windows are constantly subjected to various environmental elements, including dust, soot, pollen, UV radiation, rain, heat, and cold. However, if you invest in high-quality windows, they will prove to be resilient and require minimal maintenance. To ensure that your windows and doors maintain their desired appearance and functionality for many years, it is crucial to provide them with regular care from the very beginning. By doing so, you can maximise their lifespan and enjoy their benefits for decades to come. Not only do long-lasting windows contribute to environmental protection, but they also offer financial advantages by reducing costs in the long run.

What to use for cleaning

When it comes to cleaning windows with aluminium clad frames, the most effective approach involves using a neutral cleaning agent along with a sponge or cloth. On the other hand, for timber frames, there are specialised cleaning and care products specifically designed for this natural material, ensuring gentle treatment. Many offers a dedicated care kit through paint suppliers, which are designed to facilitate maintenance and extend the repainting cycle.

To effectively clean the glass, follow these steps:

  1. Dampen a cloth with a few drops of methylated spirits.
  2. Gently wipe the surface of the glass.
  3. Polish the glass dry using a lint-free cloth.

Avoid using commercial glass cleaners as they can potentially damage the coatings on high-performance glass and the interlay of laminated glass. Ensure that the cleaning cloths you use do not contain any abrasive substances. Additionally, be cautious not to subject the glass to extreme temperature changes, as this may result in thermal fracture. Do not direct hot or cold water directly onto the glass.

Twice a year, it is recommended to clean all hardware to remove dust and dirt. Follow these steps:

  1. Apply a light spray of a corrosion preventative, such as WD40, to hinges, gears, and strikers.
  2. Wipe off excess spray with a dry cloth. Take care not to get these compounds on the timberwork, as they may cause staining.
  3. Clean exposed surfaces by wiping them down with warm soapy water and a soft rag.
  4. Rinse the surfaces thoroughly to remove any soap residue.
  5. Apply the corrosion preventative spray as mentioned earlier after the surfaces have dried.

By following these cleaning guidelines, you can ensure the cleanliness and longevity of your windows and hardware.

Seals need to be wiped regularly with a damp cloth only, chemicals should not be used.

When constructing a new home, the considerations are seemingly endless. Cost becomes a key player in decision-making—investing upfront to save in the long run. Windows and doors, crucial components, offer an opportunity for quality choices to pay off in the future.

Opting for high-quality windows and doors isn’t just about aesthetics; it’s an investment in longevity, beauty, and energy efficiency. Moreover, such choices can significantly enhance the resale value of your home. Let’s explore some guiding principles for making informed decisions.

PLACEMENT OF WINDOWS

The positioning of windows is influenced by factors such as environment, climate, and house design. If you’re blessed with a breathtaking view, large windows can help you fully embrace it. Conversely, if neighbors are in close proximity, skylights might be a consideration, allowing ample natural light without compromising privacy.

The orientation of windows matters too. South-facing windows, larger to capture winter sun, contrast with east and west-facing ones, which should be sufficient for natural light but smaller and well-insulated.

INSULATION

Energy-efficient windows are a smart investment, saving on heating and cooling expenses. On the flip side, poorly installed or inadequately treated glass can lead to future problems.

Double-glazed windows with sun-reflecting treatments act as effective heat barriers. Consider ‘broken’ aluminum frames, featuring a non-heat-conductive material between aluminum layers, for excellent insulation.

Proper installation of glass doors and windows is crucial to minimize ‘air leakage.’ Even top-quality glass or frames won’t suffice if the installation is subpar, leading to discomfort in extreme weather.

While installing aluminum windows and doors can be complex, consulting a professional is advisable. Many manufacturers offer installation services or provide detailed instructions for confident DIYers.

Given the myriad factors at play, exploring custom windows and doors for your new build is worthwhile. Tailored to your specifications, they not only enhance aesthetics but also contribute significantly to your home’s energy efficiency rating.

A Life Without Glass

The earliest windows were, unsurprisingly, made without glass. What may astonish you, however, is the materials used to construct windows back then. Initially, windows were simply openings in the wall to allow natural light to enter. Later, thin animal hides were stretched over these openings to offer some elemental protection while still permitting soft light to filter through. Shutters could be closed in bad weather to protect those inside.

Early Glass

During the Roman era, glassmaking was quite advanced. Panes of glassy pebbles were set in wooden frames that allowed some light through, though they were not transparent. The introduction of clear glass panes occurred in the late 3rd century, when blown glass cylinders were created and then thinly sliced to produce curvy pieces of transparent glass.

Back to Basics

Unfortunately, when the Roman Empire collapsed and history entered the Dark Ages, this technology was lost. Cathedrals continued to create stained glass windows using small pieces of glass, but for the general populace, this was no longer available. The return of wooden shutters and thin animal hides ensued. Windows had to remain small, and insulating the animal hide-covered openings was nearly impossible. People turned to the use of thinly sliced pieces of horn fastened together to provide better insulation, but these windows were costly to produce and saw little use among common homes.

Windows Make A Comeback

In the Middle Ages, glassmakers began to redevelop the glass window. The French developed crown glass – a hollow bubble spun into flattened discs and laced together in lead panes (the image above is a great example of crown glass). Other glassmakers also “rediscovered” the cylinder glass technique used by the Romans over a millennium earlier. This time, however, the technology was here to stay – and glass entered the homes of the wealthy – although it was still incredibly expensive. Nobles would often routinely take their glass panes down and store them carefully when they weren’t in their homes to ensure they were not broken.

Versailles – A Legacy in the Window Industry

In the late 17th century, the French continued improving glass technology, and the clear glass window pane was cast. The Palace of Versailles – built in the 1680s – used this new and expensive technology to create the long-latticed windows that French Doors and Windows are still known for today. Yet again, glass remained quite a luxury. Apart from the wealthy, the common person of this period could only dream of having a clear glass covering for their windows.

Glass for the Masses

Glass continued to be a luxury for many years, despite improved methods for its creation. England eventually repealed duties on windows, reducing its price by about 50% in the early 19th century. People had never seen so many glass windows and could finally afford them!

Later, the use of steel as load-bearing columns in architecture allowed for the installation of “curtain walls.” Large floor-to-ceiling windows could now be used in designs, as the wall no longer needed to support the weight of the structure. This led to the modern skyscraper look of the early 20th century.

The evolution of the glass window is surprisingly recent for an item we routinely take for granted. Many are aware of how much the automotive industry or the internet have revolutionised the lives of ordinary people, but the introduction of glass windows not only changed the designs possible for people – it completely transformed our indoor environment. Insulated windows make temperature control feasible, and large clear windows are shown to increase happiness and productivity! Imagine your office life with the wind, rain, smells, and noises of the outside world constantly pouring in through a hole in the wall, and take a moment to thank your glass windows for all that they contribute to our modern lifestyles.

When the summer heat kicks in, some conservatories can quickly become uncomfortable due to the excess heat. However, with a few simple tweaks, you can create a cool and enjoyable space in your conservatory.

Whether you already have a conservatory or are thinking about getting one, consider these tips to keep it comfortably cool.

Did you know that Ireland experiences less extreme temperature variations compared to other countries, making it an ideal place to enjoy your conservatory throughout the year?

SOLID ROOFS OR SOLAR CONTROL ROOFS

Putting a solid roof on your conservatory is a great way to keep it cool and comfortable during the warmer months.

Unlike traditional glass or polycarbonate roofs, solid roofs offer better insulation, reducing heat transfer and keeping the space more pleasant on hot summer days. They also help with energy efficiency, making them a smart choice.

BI-FOLDING DOORS

To improve airflow and temperature control, consider installing bi-folding doors in your conservatory.

These popular doors are designed to enhance natural ventilation, letting fresh air circulate throughout the space.

When fully opened, they create a wide opening that seamlessly connects your indoor and outdoor areas, providing a versatile and airy environment.

ADDITIONAL TIPS FOR COOLING

Ensure proper ventilation in your conservatory by installing ceiling fans or windows that can be opened. This promotes air circulation and helps keep the space cool.

Another effective strategy is to add potted plants or greenery. Plants naturally release moisture through transpiration, cooling the surrounding air and adding a touch of natural beauty to your conservatory.
