Frequency of Testing on Developments

As further properties on a development become ready for testing, district councils should indicate at what point(s) they wish any further set(s) of tests to be conducted. Assuming no tests are failed, district councils should stipulate at least one set of tests for every ten dwellings or rooms for residential purposes in a group or sub-group. Tests should be conducted more frequently at the beginning of a series of completions than towards the end, to allow any potential problems to be addressed at an early stage. However, on large developments testing should be carried out over a substantial part of the construction period.
