Kapri - I had a look at the thread about this on the NABD forum and had a reply on the NABD forum from Gary Seddon who I knew when I was a NABD rep .......
Get him to ring the office on 0844 415 4849 Bobbi.
I know the adaptions advisor Tracey Browne has been away for a couple of weeks on tour earning a crust but she's back in Madchester now so will be getting stuck into her emails.
Rick is probably the best to ask at the moment, the dispensation for trikes adapted for use by a disabled rider is still in effect so most of the information regarding that is still current. The forms and method will still be the same. I've done it twice myself and will be doing it again once my current project is finished so you could always give your mate my email addy as I wrote the original piece. I'll be contacting all the relevant authorities about my build in the next few weeks just to check.
I might even do a re-write with the updated info.
By the way the original thread is at
grumpygaz@gmail.com and I've PM'd you his email address.
Gary's reply was to my post suggesting some of it may be outdated now...
Hope this helps!
