Stock condition data is the main starting point for the social housing sector seeking to implement strategies to meet the conditions standards of the Decent Homes Standard (DHS) by 2010. Focuses on the accuracy and consistency of surveyors' survey judgements and their potential impact on planning for the DHS. Covers: the nature of survey judgements; the benchmarking of an acceptable survey; survey client and surveyors' acceptability levels; an example of the impact of surveyor judgements; the reasons why surveyors' judgements differ and the impacts on the DHS. Concludes that survey judgement inconsistencies must be reduced with increased training being delivered to surveyors and survey managers so that they fully understand the requirements of the DHS. Tables cover the decent homes criteria, a survey of acceptable variability levels and the spread of repair costs. Figure shows risk utility functions. References.
