Got good offers, but want to defer (Web Development)

Hey,

So for the past two years instead of doing A-Levels/BTEC I completed an apprenticeship as a Web Developer. I received an unconditional offer from Hull for games development, unconditional offer from Portsmouth for Digital Media and an unconditional offer from Southampton Solent for Web Design and Development.

Southampton Solent is my main choice uni so I'm definitely looking towards that. However I'm due to start a new job at a national web design/development company which is an amazing opportunity. Will they let me defer for a year whilst I get more experience in the field which the degree is related to? I already have 2 years, plus this 1 year and also my placement year will give me 4 years professional experience (not including freelancing) before I even graduate.

thanks
