Deep Retrofitting Your Home

Transform your entire property in one comprehensive project. Upgrade your insulation, heating, and ventilation to achieve the ultimate in energy efficiency, comfort, and sustainability.

Whole House Upgrades

What Is a Deep Retrofit?

A deep retrofit is a whole-house approach to upgrading your property’s energy performance. Rather than tackling single measures one by one, a deep retrofit integrates multiple upgrades—such as high-performance insulation, airtightness, advanced ventilation, and a renewable heating system like a heat pump—simultaneously. This comprehensive strategy is the most effective way to modernise an older, inefficient house into a highly comfortable, low-carbon home.

Why Choose a Deep Retrofit?

  • Transforms cold, draughty properties into exceptionally warm and comfortable homes

  • Drastically reduces heating bills and completely eliminates reliance on fossil fuels

  • Guarantees a jump to a B2 BER (Building Energy Rating) or significantly higher

  • Tackles the entire home’s energy needs in a single, coordinated project

  • Unlocks the most lucrative, all-inclusive SEAI grant funding available

The One Stop Shop Approach

Seamless Project Management

Undertaking a deep retrofit can seem daunting, which is why we offer a fully managed One Stop Shop service. We handle every single aspect of your project, from the initial Home Energy Assessment and technical design to the installation of all measures, final BER certification, and even the grant application process. You deal with one dedicated project manager from start to finish.

The Fabric-First Methodology

We always advocate for a ‘fabric-first’ approach. This means we first prioritise maximising your home’s insulation and airtightness to drastically reduce heat loss. Only once the building envelope is fully optimised do we introduce a highly efficient, low-temperature heating system, ensuring your new heat pump operates at peak efficiency and delivers maximum savings.

Unlocking Major SEAI Funding

One Stop Shop Grants

Up to €35,000+

Homeowners undertaking a complete deep retrofit can access substantial SEAI grant funding, often exceeding €35,000, depending on the measures installed.

To qualify for the fully managed One Stop Shop grants, your home must have been built and occupied before 2011, and the completed works must achieve a minimum B2 BER rating with a significant uplift in energy performance. Grant values are conveniently deducted upfront from the total cost of your project.

Benefits of a Deep Retrofit

Total Transformation

Completely revitalise an older, underperforming property into a modern, energy-efficient sanctuary.

Massive Energy Savings

By addressing all heat loss areas at once, you will see a dramatic and permanent reduction in your energy bills.

Ultimate Comfort

Enjoy consistent, even temperatures in every room, completely free from draughts and cold spots.

Fossil Fuel Free

Transition away from expensive oil or gas boilers to clean, renewable heating technologies like air-to-water heat pumps.

Healthier Air Quality

Integrated mechanical ventilation ensures a continuous supply of fresh air while expelling dampness and indoor pollutants.

Maximised Grant Funding

Access the highest levels of SEAI funding by bundling multiple upgrades through the One Stop Shop route.

Increased Property Value

Achieving a B2 or A-rated BER significantly boosts your home’s market value and overall desirability.

Hassle-Free Process

Our end-to-end project management removes the stress of coordinating multiple trades and managing grant paperwork.
