CSH (Code for Sustainable Homes)


The Code for Sustainable Homes seeks to substantially reduce the adverse environmental effects associated with the construction and habitation of new houses.

The Code required that by 2013 all new homes should be being built to Level 4 of the Code with Level 6 (carbon neutral) being achieved by 2016.

The materials section of the Code allows developers to gain points towards Levels 4, 5 and 6 by specifying known low carbon systems for the external walls, roof and floors (Mat1) with further points available for the responsible sourcing of Basic Building Elements (Mat2) and Finishing Elements (Mat3).

Until now maximum points for fascia and cladding under Mat2&3 could only be achieved by using FSC timber, and maximum points for guttering was not achievable. However Swish now holds BES6001 Responsible Sourcing Certification which allows developers the option of specifying products that will gain them maximum CSH points as well as lasting the lifetime of the building without the need for maintenance.


Swish Cellular PVC roofline products qualify for 3 points as a Tier 1 product under Mat3, the section dealing with Responsible Sourcing of Finishing Elements.


Swish low carbon guttering systems also qualify for 3 points as a Tier 1 product under Mat3 making the swish fascia and cladding combination the only fascia and gutter system to offer maximum CSH points.


PVC Cladding installed over timber framing now carries an A+ rating. This allows developers to claim the maximum three points available under the CSH for just such an external wall system.  In addition, under Responsible Sourcing of Basic Building Elements Mat 2, Swish PVC Cladding qualifies for 3 points as a Tier 1 product.


Tier 1 products are those where the manufacturer is certified to at least BES6001 “Very Good”. In order to achieve Very Good the manufacturer is also required to hold ISO9001, ISO14001 and OHSAS18001.
