Harry Bingham from The Writer’s Workshop kindly guided me towards the answer of my question regarding novel length. Put briefly: I’ve got some serious cutting to do. Here’s what Harry has to say on average novel length:
A novel of average length is anywhere between 75 – 120,000 words. Romantic fiction tends to be at the shorter end of this spectrum. Most thrillers will be at the longer end.

Having had a search around, I also found some lists online of the word counts of books (which confirm the figures above):
