A Brief Introduction to the
Code
Matthew Weatherill
Building Control Surveyor
The Code – What is it?
• Assessment of the environmental and social
sustainability of new homes.
• National standard covering 9 key areas:
•
•
•
•
•
•
•
•
•
Energy and CO2 emissions (36%)
Water use (9%)
Materials (7%)
Surface water run-off (2%)
Waste (6%)
Pollution (3%)
Health and well being (14%)
Management (10%)
Ecology (12%)
The Code – How is it Monitored?
• Administered (enforced) through the
planning (development control) process.
• Certificates are required in HIPs
• Produced By an Independently Accredited
Code Assessor (Accredited By BREEAM or
STROMA)
• Paid for by the applicant/developer
• Design Stage assessment
• Post Construction Review including site visit
and evidence gathering

The Code - Levels
Level 0 –
• Nil Rated Certificate for HIPs
• Mandatory April 2008
• Energy and CO2 as Building Regulations
part L 2006 standards
Level 1 –
• Energy and CO2 10% improvement over
Building Regulations
• Water usage equal to part G 2010 standards
Level 2 –
• Energy and CO2 18% improvement over
Building Regulations
The Code - Levels
Level 3 –
• Likely to be mandatory
October 2010
• Many planning
departments already
asking for this level
including Redditch BC
• Energy and CO2 25%
improvement over 2006
Building Regulations;
equal to 2010 part L
standard?
• Water usage 12% less
than part G 2010
standards
The Code - Levels
Level 4 • Likely to be mandatory 2013
• Energy and CO2 44% improvement over
2006 Building Regulations
Level 5 • Energy and CO2 100% improvement over
2006 Building Regulations
Level 6 –
• Likely to be mandatory 2016
• “Zero Carbon”
• 33% improvement in water efficiency
