The Feltham Skills Centre was officially opened in 2003 by future Prime Minister Gordon Brown, then Chancellor of the Exchequer.
Spring Grove House, a Grade II listed building which forms part of the college's Isleworth campus, was the main country residence of Sir Joseph Banks from 1779 to his death in 1820 (he purchased the freehold in 1808).
It is an excellent example of late Victorian architecture and interior design, with a fine Georgian room as an added bonus.
The following year Spring Grove Secondary School moved to the house, sharing the building with the Polytechnic who offered almost entirely evening classes.
It moved to new premises in Lampton in 1959 and Spring Grove House was taken over by Isleworth Polytechnic as a full-time college.
West Thames College also gained national Beacon Awards for Equality and Diversity in 2008 and 2009.
