The Building Energy Rating or BER is an indication of the energy performance of the dwelling. It covers energy use for space heating, water heating, ventilation and lighting, calculated on the basis of standard occupancy and a range of other factors.
A Building Energy Rating or BER is similar to the energy label on your fridge with a scale of A-G. A-rated homes are the most energy efficient and G the least efficient.
BER assessments performed on new dwellings will also help determine compliance to Part L of the Building Regulations.
If you are building a new house you shall produce a printed copy of the BER certificate and advisory report to the building control authority in whose functional area the building is situated, on demand being made by that authority for its production.
On the completion of construction of the building the Final BER certificate and related advisory report shall be issued, these will take account of any changes implemented during its construction relative to the plans, specifications or other data on which the provisional BER was based.
