have a look on this site and put in DVLA it gives the translation numbers from their rip off 0870 numbers.

Dial the normal number and pay standard rates.

At least when you call they wont be getting a big kick back for keeping you hanging on.

works for most 0870- 0840 numbers,
saved me a fortune in the last few months,
when i had to keep ringing pipex to sort my bills out
