What Is A Deep Retrofit?

A deep retrofit is a full upgrade to your home. It boosts energy efficiency and cuts down on heat loss. This means less drafts, more warmth, and lower bills! Typical upgrades include wall insulation, new windows and doors, efficient lights or appliances, heating system upgrades, and even solar panel installation.

The goal is to make your home greener by reducing carbon emissions while making it more comfortable for you to live in.

In a deep retrofit project, every feature of the house gets checked with an energy audit first. Your home’s use of light, heat, and power gets tested to see where improvements can be made.

Then comes the work: adding insulation to walls or roofs; replacing old boilers with eco-friendly ones; updating lights with LED bulbs; fitting solar panels on roofs. All these changes drive down your energy use, saving you money on bills too.

The Costs of Deep Retrofits in Ireland

For internal insulation (dry lining), you can expect to pay around €1,500 for an apartment, €2,000 for a mid-terrace house, €3,500 for a semi-detached house, and €4,500 for a detached house.

If you opt for external wall insulation (EWI), the costs may be higher. According to experts at the Superhomes organisation, deep retrofit costs can range from about €25,000 for smaller and newer homes to over €70,000 for older and larger homes.

Moreover, there are grants available from SEAI that can help bring down these costs to a range of between €15,000 and €45,000 for homeowners. The total cost will depend on various factors specific to your home’s situation.

Factors Influencing Deep Retrofit Costs

The age and size of your home, as well as the complexity of the project, will determine the materials and labour needed for deep retrofitting.

Age And Size Of Home

The age and size of your home can have an impact on the cost of a deep retrofit. Older and larger homes may require more extensive work to improve energy efficiency, which can increase the overall cost.

For example, Superhomes states that older, larger homes could cost over €70,000 for a deep retrofit. On the other hand, smaller and newer homes might need less work and therefore have lower costs.

It’s important to keep in mind that every home is different, so it’s hard to give an exact estimate without assessing your specific situation. However, by considering the age and size of your home when planning a deep retrofit, you can better understand the potential costs involved and make informed decisions about improving energy efficiency in your property.

Complexity Of Project

Deep retrofit projects can vary in complexity, depending on factors such as the age and size of your home. Older homes may require more extensive upgrades to meet energy efficiency standards, which can increase the complexity of the project.

Additionally, large or uniquely designed homes may involve more intricate installation processes.

Factors like insulation type and renewable energy system installations can also contribute to project complexity. For example, installing solar panels or upgrading heating systems requires careful planning and coordination with professionals.

Navigating the technical aspects of deep retrofitting can be challenging for homeowners. The process involves understanding building regulations, coordinating with contractors, and making informed decisions about materials and technologies.

However, despite these complexities, undertaking a deep retrofit is an important step towards improving energy efficiency and reducing carbon emissions in Ireland. With the right support from experts and organisations like SEAI (Sustainable Energy Authority of Ireland), you can successfully navigate through these challenges while creating a more sustainable home.

Materials and labour

When it comes to deep retrofits, the cost of materials and labour is an important factor to consider. The type of insulation you choose and the size of your home can influence these costs.

Internal insulation, like dry lining, can range from €1,500 for an apartment to €4,500 for a detached home. External wall insulation (EWI) may be more expensive. Overall, a deep retrofit can cost between €25,000 for smaller homes and over €70,000 for larger ones.
