Hello and Welcome
I took the liberty of emailing the DSA as I am interested, I have no idea how long it might take them to reply, you might want to call them.
email address for the DVLA and DSA are below
drivers.dvla@gtnet.gov.uk Telephone: 0870 240 0009
cbt@dsa.gsi.gov.uk Phone: 0115 936 6547
Hope this helps
Richard
