BREEAM (Building Research Establishment Environmental Assessment Method) can be used to assess the environmental performance of any type of building (new and existing).

These versions all look at the same broad range of environmental impacts:

  • Management
  • Health and Wellbeing
  • Energy
  • Transport
  • Water
  • Material and Waste
  • Land use and Ecology
  • Pollution


Credits are awarded in each of the above areas according to performance. A set of environmental weightings then enables the credits to be added together to produce a single overall score.

The building is then rated on a scale of: PASS, GOOD, VERY GOOD, EXCELLENT or OUTSTANDING and a certificate is awarded to the development.

As part of our commitment to water conservation, we have assessed how our products can help a building design achieve BREEAM credits and hence a higher overall BREEAM rating. To achieve an OUTSTANDING rating for example, a building design will need to obtain 2 credits under the Wat 01 category.
