Understanding Society User Support

I work as a researcher at Centre for Cities and we're interested in using data from Understanding Society in one of our current projects looking at mobility across the UK. We'd need the data at LA level so would need to apply for a special license. I've looked at the information on your website and on the UK data service website but couldn't find any information on how much it’s likely to cost to get the data - can you give me an idea of the typical cost?

I did send this as a email to info@understandingsociety.ac.uk but was told to ask the question on here.

Thanks
