• Residential BER Certs

BER Requirement

Since January 1st 2009, existing dwellings are required to have a BER certificate when offered for sale or let. New dwellings, where the planning permission was applied for on or after January 2007 also require a BER certificate.

At Net Zero we have a number of SEAI registered Residential BER Assessors on our team who are some of the most experienced in the industry.  We offer quick turnaround times from building survey to published certificate.

  • What Is Involved?

    In order to produce a BER certificate one of our assessors will need to survey the dwelling.  When you book a BER assessment with us we will schedule an appointment for a time that is most convenient for you.  It is important that the assessor has access to all areas of the house.

    During the survey, the assessor will sketch the layout of the dwelling and its measurements.  The survey is completely non intrusive.  The calculations are based purely on the materials and heating equipment that are present, it does not matter how well the equipment is working or how it is used.

    During the survey the assessor will be measuring the area of the rooms, measuring the windows, the thickness of the walls, the levels of insulation, the heating system, the number of flues, the floor types and the wall types.  The assessor typically collects approximately 80 pieces of data which describe your home. The survey itself usually takes about an hour but can vary with the complexity or size of the dwelling.  They will then use this data in their calculations when producing your building energy rating.

  • What Should I Provide?

    -The year of construction of the dwelling if known.

    -MPRN number (This is found on an electricity bill for the property).

    -Details of any upgrades, extensions or conversions e.g improving insulation.

    -Safe unobstructed access to all areas of the dwelling.

  • What Happens After the Survey?

    After the survey, the assessor will return to our office and perform all the relevant calculations using the data gathered at your home.  They will then enter this into the DEAP software provided by SEAI.  This software calculates the BER rating. The assessor then publishes the BER certificate and advisory report via the SEAI website.  We will then forward the BER certificate and advisory report on to you via email and or post you out a hard copy.  We can also send a copy to your solicitor or estate agent if you wish.
