Kevin Firth has created some software to update the UK Airspace Boundaries using the data held in the UK Integrated Aeronautical Information Publication. http://www.nats-uk.ead-it.com/public/index.php%3Foption=com_content&task=blogcategory&id=165&Itemid=3.html
If anyone would like to try out this files then please download herehttp://www.uk2000scenery.net/files/UK_Airspace_Boundaries.zip
These files will both alter your default UK Airspace database and add new areas. So please read the README first showing you how to install and which files to backup. Users are welcome to post any feedback or report problems so the file set can be improved.
From my point of view I will be using these in combination with my own AFCAD alteration to try and ovoid pointless ATC transfers.
