Commercial BER Certs in Cork, Sorted Fast

Selling or letting a commercial property in Cork? You need a valid Commercial BER cert before it goes on the market — and the rating has to appear in every advertisement.

A commercial BER certificate (also called a non-domestic BER) is a legal requirement under S.I. No. 243 of 2012. It applies to offices, retail units, warehouses, restaurants, pubs, hotels, gyms and industrial premises. No cert, no sale, no letting.

Commercial BERs are carried out by an SEAI-registered non-domestic assessor working with us, and we handle the whole thing for you from the first call to the published certificate. Site survey, energy assessment, certificate published on the SEAI National BER Register — plus an Advisory Report showing exactly how to improve your rating.

What Is a Commercial BER Cert?

BER stands for Building Energy Rating. It’s an energy label for a building, graded A to G — A is the most efficient, G the least.

A commercial (or “non-domestic”) BER covers everything that isn’t a home: offices, shops, warehouses, restaurants, pubs, hotels, gyms and industrial units. Every cert comes with an Advisory Report — a practical list of upgrades to improve the rating and cut your energy bills.

You need one if your property is:

  • Being sold — the cert must be in place before it’s advertised
  • Being let — including sub-lettings of individual units
  • Newly built — required before it’s occupied or used
  • Being sold off plans — a provisional BER is needed, valid for 2 years


The rating must also appear in every advertisement — property portals, agent listings, brochures and window displays. And where a property has multiple units offered separately, each one usually needs its own cert.

Commercial BER in Cork: What You Need to Know

Who needs a cert, how the assessment works, and what to watch out for before you go to market. Most commercial BER questions come down to timing and paperwork, get both right and the cert is a formality rather than a delay on your sale or letting.

You need a valid commercial BER cert if your property is being sold, let, newly built, or sold off plans.

  • Applies to offices, retail, warehouses, restaurants, pubs, hotels, gyms and industrial units
  • The rating must appear in every advertisement — portals, agent listings, brochures, window displays
  • Where units are let separately, each one usually needs its own cert


No cert means fines of up to €5,000 per offence under S.I. 243 of 2012.

  1. Quote — Send us the address, building type and floor area. Fixed price back the same day.
  2. Survey — We measure the building and record construction, heating, lighting and ventilation. Non-intrusive — drawings and spec sheets improve your rating.
  3. Certificate — Published to the SEAI register and emailed to you, with an Advisory Report showing how to improve the grade.


Small units take a couple of days. Larger sites, about a week. Working to a closing date? Tell us and we’ll prioritise it.

  • Valid 10 years — unless you carry out works that change the building’s energy performance
  • Only an SEAI-registered non-domestic assessor can issue one. A domestic BER won’t do
  • Provisional certs for off-plan sales are valid 2 years
  • Owners and agents must produce the cert on demand to an authorised officer


Already have a cert? Send us the address and we’ll check the SEAI register for you.

Some buildings don’t require a BER. The main exemptions:

  • Protected structures and national monuments
  • Places of worship
  • Temporary buildings with a planned use of two years or less
  • Certain industrial, workshop and agricultural buildings with low energy demand
  • Small standalone buildings under 50 m²


Exemptions are easy to misread. Talk to us before you advertise the property.

A Display Energy Certificate shows a building’s actual measured energy use, and has to be displayed publicly.

  • Over 500 m² with frequent public access
  • Over 250 m² occupied by a public body with frequent public access
  • Renewed annually — we look after these too
