I wasn't aware you could expedite the visa delivery, but we didn't, and it only took 7 days to get back to us.
At any rate, since the courier service is contracted, by SMS, you may want to contact them regarding expedition fees:
SMS on 08709 501 760 <-- this is the number for them I found on the London Embassy site.
Here is also a FAQ which has information regarding the interview and courier service:

Thanks for your reply. Seems the Courier service options only refer to the time the visa is delivered the next day. Before 8AM additional £20, before 10AM additional £10 up to 12 PM additional £5.It wont really expedite aything by much as the London Embassy processing can still take the 5 days from date of Interview.Thank you for replying and your help.Good Luck.Mike
