Lets Go Green Deal can advise build and architects on how to meet new Government codes for Eco or Sustainable Homes.

In April 2007 the Code for Sustainable Homes replaced Eco-homes for the assessment of new housing in England. The Code is an environmental assessment method for new homes based upon BRE’s Eco-homes and contains mandatory performance levels in 6 key areas.


The Code aims to protect the environment by providing guidance on the construction of high performance homes built with sustainability in mind.

BRE and CLG have worked closely together to ensure that the Code meets the latest regulatory requirements and addresses issues that emerged from an earlier industry wide consultation.


The Scope of the Code

Many house builders who currently use Eco-homes will find the credit system of the Code familiar. Users will notice that there are new mandatory minimum levels of performance that have been introduced across 6 key issues:

  • Energy efficiency /CO2
  • Water efficiency
  • Surface water management
  • Site Waste Management
  • Household Waste Management
  • Use of Materials



The Code Scoring System

The Code has a scoring system of six levels. The different levels are made up by achieving both the appropriate mandatory minimum standards together with a proportion of the flexible standards. Code Level 3 is approximately equal to the Eco-homes VERY GOOD score.

Further information regarding the Code including a copy of A step-change in sustainable home building practice can be downloaded from the CLG website.



Compliance with the Code

Code assessments are carried out in two phases:

An initial assessment and interim certification is carried out at the design stage

Final assessment and certification is carried out after construction see below:

Design Stage Review

Based on design drawings, specifications and commitments Results in interim certificate of compliance

Post Construction Review

Based on the design stage review Confirmation of compliance including site records and visual inspection.

Eco-homes is a version of BREEAM for homes. It provides an authoritative rating for new, converted or renovated homes, and covers houses, flats and apartments.

Eco-homes balances environmental performance with the need for a high quality of life and a safe and healthy internal environment. Many of the issues are optional, ensuring Eco-homes is flexible enough to be tailored to a particular development or market.

Eco-homes Assessments can be carried out at both the design stage or post construction for:

  1. New build
  2. Major refurbishment projects
