The original Denbigh School opened September 1964 where half of Wilton high's students were part of the initial intake for the school, which was located on land at the northern end of Cornwall Grove in Bletchley. In the 1980s, the Local Education Authority resolved to relocate either Denbigh or (nearby) Lord Grey School (Formerly Wilton) to Shenley Church End, a few miles to the north. Eventually Denbigh was chosen to move. In 1991-1992 term years 8 and 9 were located at the new school and other years located at the old one, the school was still in the process of being built at the time. All years moved into the new school in July 1992.
