What is a Thermal Performance Assessment?

A Thermal Performance Assessment by an ABSA Accredited Assessor is essential in reducing the ongoing running costs of your home with recommended guidance towards the orientation of your living spaces, building material & window options, as well as many other technical specifications. This includes information on design & construction, climate, all as common patterns of household use.

Nationwide House Energy Ratings Scheme Explained

Upon completion of a Thermal Performance Assessment, an ABSA Accredited Assessor will supply each home with a unique NatHERS certificate as confirmation of the star rating of their new home or renovation. This allows builders, certifiers and regulatory authorities to confirmation that a building has been built to the design on which the energy rating is based.

Further information on NatHERS certificates can be found here.
