Code for Sustainable Homes (CfSH) is an environmental assessment method for rating and certifying the performance of new homes.  

Since March 2016 CfSH is no longer a legal requirement, however many local authorities, London boroughs and planning officers still work to CfSH standards and may require it for proposed new developments.

CfSH has six different rating levels, each representing a decrease in carbon emissions and an increase in sustainability standards across nine categories. 

A ‘zero carbon home’ would receive the top rating of CfSH Level 6.

There are three difference phases to a CfSH assessment; pre-assessment, design stage and post construction stage.  

You will need to achieve credits within the nine different code categories and the number of credits will depend on the level required. The nine categories are:

  1. Energy and CO₂ Emissions (m)
  2. Water (m)
  3. Materials (m)
  4. Surface Water run-off (m)
  5. Waste (m)
  6. Pollution
  7. Health and Well-being (m)
  8. Management
  9. Ecology

Some of the categories have mandatory (m) elements that must be achieved relating to the CfSH level you are seeking to achieve.  With regards to Health and Well-being, the Lifetime Homes Category is also mandatory if you are undertaking a Level 6 assessment. 

How we can help:

Our experienced Assessors will provide you with a design consultation to ensure your project is designed to achieve your required CfSH standard.  We will break down the requirements for your project into easily understandable sections – no jargon, no complications. We work to keep things simple. We will keep you updated on your progress at all times.

Our CfSH service incorporates all the calculations, assessments and certificates required to take your project from design to completion. Our value-for-money package includes free site registration and free EPCs.

As part of our service we provide you with:

  • Materials Calculations 1, 2 & 3
  • Pol 1 & 2 checklist and information
  • Continually updated CfSH Evidence Tracker

We can also provide additional services that can complement your CfSH assessment:

We can support all different project sizes and CfSH levels from single units to large developments, from Code Level 1 to Code Level 6. We can assess your project at the design stage or at the post-completion stage. However, we would suggest that CfSH guidance is sought early to ensure that you get the best advice and guidance to enable your project to achieve the required standards.
