ETA: you can search phone directories online up to 1984 at ancestry.co.uk, but it's geared towards searching for people's names.
as well as the 'search' function, you can just browse and open up any directory and see each page as an image (like i got the met police listing above) of any page - you don't have to scroll through page by page, but it's a bit long winded jumping (for example) to page 200, seeing that's too far, then to 150, and going forward to 153 to get the right page, which for the 1984 London phone book (the latest they have) gets this -
