We can assist your architect / Engineer with specification to show compliance with Part L of the building regulations.
These specifications include, floor insulation, wall insulation, roof insulation, windows & doors, air tightness, Ventilation Systems, Primary and secondary heating systems.
We can then use these specifications in the Provisional building energy rating to show compliance with the building regulations.
It is important to get this done before you start building so you can use the specification for tenders to builders / Sub-contactors
