Part L1b Assessments for extensions & conversion projects

A new extension or conversion to a residential property will more than likely require a Part L1b Assessment if the new glazing area is more than 25% of the new floor area.

Our experience energy assessors will be able to carry out early design stage calculations to determine the most suitable design by combining an efficient building fabric, services, and if required cost effective improvement to the existing house. Our design recommendations are based on an efficient design, as well as the economical benefits to give you and your building the most suitable solution.
