A Warmer Home and Lower Energy Bills: What Irish Homeowners Should Know in 2026

Energy bills are rising. But do you really have to put up with it?

For many homeowners, higher bills have become a reason to take a closer look at their home.

Older insulation, heat loss through the roof and walls, an inefficient heating system or older windows can all increase the amount of energy needed to keep a home at a comfortable temperature.

That is why energy efficiency is not just about saving money. It is also about how warm your home feels in winter, how comfortable it is to live in, and how much you may need to spend on running and maintaining it over the coming years.

Why energy efficiency becomes more important after 45

After the age of 45, many homeowners start paying more attention to the long-term costs of running their home.

If you have lived in your house for many years, the insulation, heating system, windows or doors may be much the same as they were a decade or more ago. At the same time, energy costs and expectations around home comfort have changed.

Something that seemed perfectly normal 10–15 years ago could now be contributing to unnecessary heating costs.

For homeowners aged 45 and over, the issue can be particularly relevant. The goal is often to maintain comfort, avoid unnecessary energy costs and gradually make the home more efficient for the years ahead.

Find out which options could be relevant to your situation.

A simple trick homeowners over 45 should know about

One of the simplest ways to start looking at your energy costs is not to rush into choosing specific equipment or carrying out expensive work.

First, it can make sense to understand where your home may be losing energy and which improvements could make the biggest difference.

For one home, this might mean improving attic insulation. For another, it could be upgrading the heating system, replacing windows or doors. In some cases, solar panels may also be worth considering.

The key is to look at the needs of the property first and then decide which improvements should take priority.

What can you change to make your home more energy efficient?

There is no single solution that will suit every home. It depends on the age and condition of the property, its construction, the heating system and where most of the heat is being lost.

Some of the most common areas for improvement include:

Attic and roof insulation

A properly insulated attic can allow heat to escape from the home. Improving this area can help reduce heat loss and make it easier to maintain a more consistent indoor temperature.

Wall insulation

For some properties, improving the insulation of the walls can be appropriate and can help the home feel more comfortable and reduce the amount of heating needed.

Modern heating

An older heating system may be less efficient than newer options. Depending on the property, homeowners may consider a heat pump or upgraded heating controls.

Windows and doors

Older windows and doors can contribute to heat loss. Upgrading them may form part of a wider home energy improvement project.

Solar panels

Solar PV can help a household generate some of its own electricity. Homeowners should also consider whether installation is eligible for available supports.

However, solar panels are just one possible option. For some homes, improving insulation or upgrading the heating system may be a more important first step.

Not every home needs the same upgrades

1. Two homes on the same street can have completely different energy-efficiency needs.
2. One homeowner may be losing most of their heat through the attic.
3. In another property, the main issue could be an older heating system.
4. For someone else, Solar PV could be a useful addition.

That is why it is worth understanding which improvements actually make sense for your home before starting work.

What financial support may be available?

Ireland has a range of schemes designed to support homeowners who want to improve the energy efficiency of their homes.

Depending on the particular scheme and the property, support may be available for:

• attic and wall insulation;
• heating upgrades;
• heat pump installation;
• windows and doors;
• solar panels;
• other energy-efficiency improvements.

Government grants are available for certain types of work, but the amount of support and the conditions will depend on the particular project and whether the property meets the relevant requirements.

So rather than simply asking, “Is there a grant?”, it can be more useful to ask:
“What types of support could be available for my home?”

Could you already be paying more than you need to?

If your home is older and very little has changed in recent years, it may be worth taking a closer look at its energy efficiency.

This may be particularly relevant if you notice that:

• your home cools down quickly in winter;
• you need to use a lot of heating to maintain a comfortable temperature;
• your electricity or heating bills seem unusually high;
• some rooms are noticeably colder than others;
• the insulation has not been upgraded for many years;
• your heating system is several years old;
• you plan to remain in your home for many more years.

This does not necessarily mean that you need a major renovation. But it can be a good reason to look at what options are available.

What are Irish homeowners changing in 2026?

Today, energy efficiency is seen as more than simply a way to reduce household bills. For homeowners, it is also about comfort and managing the long-term cost of running a property.

That is why a home upgrade can start with a simple step — identifying the areas of the property that may need the most attention.

From there, homeowners can consider different options:

01Insulation

02Heating

03Windows & Doors

04Solar Energy

05Whole-home upgrades

You do not necessarily have to do everything at once. In many cases, it may make more sense to identify the priorities and improve the home gradually.

Could your home qualify for support?

This depends on more than one factor. When assessing the available options, things such as the following may be relevant:

Type of property

Different types of homes may have different conditions and requirements.

Age of the property

Some schemes have requirements relating to when a property was built and occupied.

Ownership

The conditions may vary depending on who owns and lives in the property.

Current condition of the home

It is useful to understand which energy-efficiency improvements have already been carried out and what could still be improved.

Type of upgrade

Insulation, heating, Solar PV and other improvements may be covered by different schemes and have different requirements.

That is why the options available should be checked based on the individual property.

Don’t put off looking at your home

The longer a home goes without necessary upgrades, the longer its owner may continue spending money on heating and electricity.

If you plan to stay in your home for many years, improving energy efficiency can be a long-term investment in comfort and running costs.

You do not need to decide immediately which work should be carried out.

The first step is to understand what could be relevant to your home and which support options are worth checking.

Check the options available for your home

If you have been thinking about making your home warmer, reducing energy costs or finding out whether support may be available, you can start with a simple check.

Provide a few basic details about your home and select the area you are most interested in.
