Question 1

Do I need a commercial BER to sell or rent my property?

Accepted Answer

Yes. Since 1st January 2009, all existing commercial buildings in Ireland offered for sale or rent must have a valid BER certificate. The BER must be in place before you advertise the property.

Question 2

How much does a commercial BER cost?

Accepted Answer

Commercial BER costs vary from around €280 for small properties to €2,500+ for large complex buildings. Price depends on building size, type, and complexity. All prices include the SEAI registration fee.

Question 3

How long does a commercial BER assessment take?

Accepted Answer

The on-site survey typically takes 1-2 hours for small properties and a full day for large buildings. The certificate is usually ready within 48 hours for straightforward assessments.

Question 4

What's the difference between a domestic and commercial BER?

Accepted Answer

Commercial BERs use different software (NEAP vs DEAP), require higher assessor qualifications (Level 8 for complex buildings), and involve more detailed assessment of HVAC, lighting, and building management systems.

Question 5

How long is a commercial BER valid for?

Accepted Answer

A commercial BER certificate is valid for 10 years from the date of issue. You may want a new one sooner if you've made significant energy improvements.

Question 6

Are any commercial buildings exempt from needing a BER?

Accepted Answer

Yes — exemptions include protected structures, places of worship, buildings under 50m², and low-heated agricultural/industrial buildings. The exemptions are narrower than most owners expect.

Question 7

What do I need to prepare before the assessment?

Accepted Answer

Useful documents include building plans, heating system details, insulation information, window specifications, and access to all areas including plant rooms. Don't worry if you don't have everything — we work with whatever is available.

Question 8

Can I get a BER for a mixed-use building?

Accepted Answer

Yes. Commercial portions receive a commercial BER and residential portions receive a domestic BER. We can handle both through our residential and commercial assessment services.

Question 9

What happens if I don't have a BER when selling or renting?

Accepted Answer

SEAI can impose fines of up to €5,000. Practically, estate agents won't list your property without a BER and solicitors won't complete transactions without one.

Question 10

Do you cover all of Ireland?

Accepted Answer

Yes. We provide commercial BER assessments nationwide across all 26 counties with no additional travel charges for most locations.
