What is Part L?

The building regulations are coded by subject, and run from part A to P, Part L refers to thermal efficiency standards and affects insulation and heat loss. 

What’s New?

The amended regulations on energy efficiency are now in effect — and as Douglas Adams said, “Don’t Panic”.

 

Element 2006 U-value New value
Roof 0.16 0.15
Wall 0.3 0.2
Floor 0.22 0.15
Windows 1.8 1.6
Doors 1.8 1.8
Permeability 10m³/hr

7.5m³/hr

 

As with all Government documents, the paperwork surrounding the new Building Regulations is daunting – around 600 pages of it – but actually it all boils down to two main points: the method of measurement shifts from elemental U-values to actual CO2 emissions and all domestic buildings need to show a 25% improvement on CO2 emissions over the 2006 standard.
