About the service
What is it:
A Commercial BER cert is an energy label for non-domestic buildings, rating them on a scale of A to G based on their energy performance. It measures how efficiently a building uses energy across its heating, cooling, lighting, ventilation and hot water systems.
The rating is calculated using NEAP, the government approved software for non-domestic buildings, and is required by law in a range of situations.
Who Needs it:
You'll need a Commercial BER cert if you are:
- Selling or leasing a commercial property
- Constructing a new commercial building
- Carrying out a major renovation or extension
- Managing a public building over 250m²
How it works:
- One of our assessors visits the property and carries out a detailed survey
- The building is modelled in NEAP software to estimate average energy usage
- We produce graphical illustrations of the major sources of energy use
- We prepare an advisory report outlining the most cost-effective ways to improve the rating
- The rating is submitted to SEAI for approval and the cert is published
What you get
- Your official Commercial BER certificate published to the SEAI register
- A detailed advisory report on improving your rating
- Both delivered within 48 hours

Home Energy Rating (BER)
A BER cert is essentially an energy label for your home, rating it from A to G so you know exactly how efficient it is and what it's costing you to run.

New Build Energy Compliance (Part L)
If you're building a new home or carrying out major renovation works, we make sure your project meets the energy efficiency standards required under Irish building regulations.

Deep Retrofit Design
From your pre-works assessment right through to your final cert, we take care of the technical side of your One Stop Shop retrofit.

Building Regulations Compliance (Part L)
We guide developers, architects and building owners through the energy efficiency requirements for new commercial builds and major renovations, making sure everything is compliant before sign-off.

Energy Certificates for Public Buildings (DEC)
If you manage a public building like a library, leisure centre or council office, we produce the Display Energy Certificate you're legally required to show on your premises every year.

Advanced Building Modelling (IES)
Using specialist simulation software approved by SEAI, we build a detailed digital model of your building to accurately calculate energy performance, carbon emissions and compliance.
