In order to ensure buildings meet the Part E Standards, Pre-Completion Testing is being enforced. An exception is when a building conforms to a Robust Detail (RD) document, which contains details of those constructions that perform consistently well and do not require on site testing.
The Regulations state that one in ten of each construction type requires testing (selected at the Building Inspector's discretion). If a failure occurs then the construction will need to be improved and re-tested.
