When You Need a Commercial BER

  • Selling - a valid BER must be in place before a commercial property goes to market, and buyers’ solicitors will ask for it up front.

  • Letting or lease renewal - landlords need a current certificate to advertise and to complete a letting.

  • Refinancing - lenders increasingly request an up-to-date BER as part of financing and energy-linked lending due diligence.

  • ESG reporting - a lodged BER gives you a verified, comparable measure of energy performance for sustainability reporting.

  • New builds and major renovations - projects must demonstrate Part L and NZEB compliance, which ties directly into the final BER.

Fast Turnaround Times

Most quotes are issued the same working day - larger or more complex sites may take a day or two. After the site survey, we build the energy model using the correct non-domestic methodology and lodge your certificate with SEAI without delay, so you can put your property on the market or complete your transaction as quickly as possible. Working to a sale, letting or refinancing deadline? Tell us the date and we will plan the survey and lodgement around it.

Projects

Straightforward Process

  1. Request a Quote
    The price of a commercial BER cert depends on the building type, floor area, location and layout. Send us a short description of your property and we will come back with a fixed, competitive quote - same day for most buildings. Fees start from €275 + VAT for small, simple properties.

  2. Building Survey
    One of our BER assessors will visit your property to carry out the survey. They will measure all the rooms in the building and take note of heating systems, lighting, hot water systems, ventilation, glazing etc.

  3. BER Cert emailed without delay
    The assessor will produce a computer model of your building and calculate the BER rating using the latest technology. The BER cert is then published on the SEAI database and we email you a copy of the BER cert and an advisory report.

Frequently Asked Questions

  • Because commercial BERs require detailed survey work and modelling, turnaround is longer than residential. Small, simple commercial properties can usually be completed within a day or two; large complex campuses can take a couple of weeks. We estimate turnaround when providing a quote, and urgent turnarounds for closing dates can usually be accommodated — contact us to confirm availability.

  • A commercial BER is valid for 10 years from the date of issue, provided no significant works are carried out that would affect the building's energy performance.

  • A commercial BER is required when a non-domestic building is sold, let, or newly constructed in Ireland. The rating must be available to prospective buyers or tenants and must appear on all sales and letting advertisements. Estate agents generally will not advertise a commercial property without one. In addition, banks now frequently require a BER when refinancing commercial property.

  • Fees depend on building size, use class (office, retail, warehouse, industrial, etc.) and complexity. The smallest and simplest commercial units start from around €275 + VAT, with larger, more complex sites going into the tens of thousands. Contact us with your building details for a same-day quote.

  • It generally depends on the purpose of the BER. If selling a block as a whole in one transaction, a single BER cert could suffice. If renting out a small portion of a large mixed-use building, it may be more appropriate to just assess that area. The general principle is that the BER cert should represent the area being offered for sale or let. We can advise on the right approach for your situation.

  • Commercial BERs can only be issued by SEAI-registered Non-Domestic BER Assessors. To register, an assessor must have a Level 7 degree or qualification in a discipline related to building construction such as architecture, mechanical engineering, quantity surveying, etc. The assessor must use accredited Non-Domestic Energy Assessment Procedure (NEAP) software. Net Zero is a registered SEAI Non-Domestic BER Assessor with experience across commercial use classes nationwide.
