Code for Sustainable Homes

Our homes account for around 27% of the UK's carbon emissions, a major cause of climate change. The Department for Communities
and Local Government laid the foundations for greener housing when it launched the Code for Sustainable Homes in 2007. Since May 2008 all new homes are required to have a Code rating against the Code and for a Code certificate to be included within the Home Information Pack(HIP).

Code homes are built to the standards set in the Code for Sustainable Homes (the Code). They are more energy and water efficient, produce fewer carbon emissions and are better for the environment.

Code homes also encourage their owners to live a more sustainable lifestyle and are built in a more efficient way, using materials from sustainable sources. This creates less waste and also means Code homes have lower running costs.

There are nine categories in the Code covering energy, water, the materials used in the home through to health and well being and pollution with points assigned to each category.

When a builder chooses to incorporate a specific feature they are awarded points, which when added together, form the basis of a hotel-style star rating system.

The Code sets minimum standards for energy and water use.

How the Code works

The Code uses a 1 to 6 star rating system to communicate the overall sustainability performance of a new home. A home assessed as 6 stars will have achieved the highest sustainability rating. The results of the Code assessment are then recorded on a certificate assigned to the dwelling which can then be used as part of the Home Information Pack (HIP).

A Code assessment can only be carried out by a licensed and accredited Code assessor. This ensures the rating is independent and trustworthy. In order to build to the Code, a builder needs to hire the services of a Code assessor. They can advise what features need to be installed to achieve different levels of the Code.

Why we need the Code

We are committed to protecting and enhancing the environment and tackling climate change. We know that buildings contribute almost half of the UK's carbon emissions. Our long-term goal is to reduce carbon emissions by 60 per cent by 2050, and to achieve this we need to make sure new housing is much more sustainable.

The Code minimises the environmental damage from the construction process and offers an opportunity to revolutionise the design of new homes so that the housing market encourages people to live more sustainable lifestyles.

For housing industry members, adopting the Code is an important step towards our target that all new homes built from 2016 must be zero carbon rated.

Mandatory ratings

From April 2008, all new social housing must be built to a minimum of Code level 3. The Code is voluntary for privately built housing. However, also since May 2008 all new homes are required to have a Code rating in the Home Information Pack (HIP). This means that homes built to, and assessed against the Code, must include the Code certificate within the H IP.

Homes not assessed against the Code must include a nil-rated certificate of non-assessment in the HIP. These nil-rated certificates are available for free from the HIPs website www.homeinformationpacks.gov.uk

Building a home to the Code means that sustainability is designed in.
By building to Code standards, we can make Britain's homes more
environmentally friendly for the future.
