abstract:The Building Research Establishment (BRE) is a former UK government establishment (but now a private organisation) that carries out research, consultancy and testing for the construction and built environment sectors in the United Kingdom. The BRE is headquartered in Watford with regional sites in Glasgow and Swansea.
The BuildingResearchEstablishment says if builders were forced to achieve the "excellent" grading on its rating system, it would put around 1% on the cost of the average home.
