Code for Sustainable Homes
All new dwellings now require a mandatory rating against the Code for Sustainable Homes. Previously, this voluntary rating system was restricted to a handful of environmentally conscious developers. The introduction of this standard marks the start of a new era for residential architecture by aiming to make all UK homes carbon neutral by 2050. It is owned by CLG and has become a mandatory rating system as of 1st May 2008.
The code introduces minimum standards for energy and environmental factors affecting the sustainability of a home.
Ratings assess the dwelling on a scale of zero to six stars rating, level 6 being carbon neutral.
| The code is organised into the following categories: |
|
|
- Surface water run-off
- Waste (household and site construction)
- Pollution
|
- Health & Well-being
- Management
- Ecology
|
Ratings against the code will be mandatory for all dwellings from 2008 either in the form of a Nil or a 0-6 star rating, which may be assessed at design stage but must be assessed on completion of construction to obtain Final Certification.
The Government are committed to cutting carbon dioxide emissions by 60% by 2050, (relative to 1990 levels). Introduction of the Code for Sustainable Homes will have a significant impact toward achieving this target, the code also address’s other significant environmental issues relating to how we build and live in our homes.

“The training was carried out by Keith Ferguson and Steve Marriott who we felt were both knowledgeable and helpful in explaining the complexities of the Code and its implications on our projects.
Each section of the Code was explained in details and our questions were answered in a professional manner where we had concerns over certain areas. The three days which included the exam covered the topic in detail and has greatly assisted us in understanding the Code”

Nil-rated certificate: background and guide to completing the certificate
Background
The Code for Sustainable Homes (the Code) is an assessment and rating system for new homes. It aims to improve the overall sustainability of new homes by establishing a single national framework within which the home building industry can design and construct homes to higher environmental standards.
It is now compulsory for every new home in England to have a rating against the Code and for information on this rating to be provided to prospective purchasers through the HIP. This rating will make it clear whether the home has been built to the Code or not, and if it has, what standard it has achieved.
The HIP will either have to contain i) a certificate (or interim certificate) showing the rating that the home has received in respect of the Code or ii) a nil-rated certificate showing that the home has only been designed to meet current Building Regulations.
Where a home has been built to the Code, a Code certificate showing the star rating will be available from the licensed Code Assessor who carried out the assessment. Where the home has not been built to the Code, the nil-rated certificate, provided free of charge here, can be downloaded, completed and included in the HIP.
Completing the Nil-rated Certificate
The nil-rated certificate is available to download here in two forms: 1) a locked Word document and 2) a pdf file. There are three areas on the forms that will need to be completed before a certificate can be included in the HIP:
- the address
- the developer’s name
- the date the certificate was produced.
An example of a completed certificate can be downloaded here. The pdf file can be downloaded here. A word version is here.
