We can play a critical role in designing, evaluating, and coordinating energy upgrades throughout your project.

Our Service Includes:
- Pre-works BER.
- Design a whole house retrofit solution, including insulation, ventilation, heating systems (e.g., heat pumps), and solar PV.
- Ensure all designs and specifications comply with SEAI and NSAI standards.

- Post-works BER & Advisory report.
Retrofit Projects and Extensions are NOT exempt from Part L of the Building Regulations
Projects undergoing deep renovations and refurbishment that exceed 25% of the total surface area of the building’s envelope must reach a ‘B2’ Building Energy Rating.
The following are examples of measures that would trigger the regulations if the surface area being upgraded exceeds the 25% threshold:
- External wall insulation upgrades
- Internal wall dry lining
- Window and door replacement
- Replacement of the roof structure
- Replacement of floors
Extensions which affect more than 25% of the total surface area of the building would also be considered a major renovation and would be required to meet TGD Part L 2019.
You can still upgrade shallow measures in your home without triggering major renovations. This includes:
- Cavity wall insulation upgrades
- Attic insulation installed between the joists at ceiling level
- Painting or re-plastering
- Re-slating or re-tiling a roof
The cost optimal performance level for retrofit works is 125 kWh/m2/yr, or a B2 Building Energy Rating.
We are on hand throughout your project to provide advice and guidance.
