The institution was formed by a merger of Crawley and Haywards Heath colleges, in Sussex.
Mr Blair confessed to his own limited DIY skills when a student (pictured above) showed him how to fix a tap. "I am always looking to learn but I am definitely not trying that," he said.
The college has nearly 1,000 staff and more than 3,000 full-time and 15,000 part-time students.
Russell Strutt, the principal, said: "It is wonderful for him to see at first-hand our newly formed college and our ambitious plans for the future."
Mr Blair said: "We have to recognise the importance of vocational skills for our future - education, training and skills are key. I wanted to come here to use this as a symbol of what we are trying to achieve countrywide."
