The UK has always run a system of "full cost recovery" for consular services. This means that things are expensive where they can charge and usually administered by locally employed staff. This contrasts with other countries who subsidise things a bit more. The result is that a Brit will feel a bit ripped off whilst a Kiwi might end up having a night on the town with a compatriot. I don't think this has changed over the years.
The general problem I was referring to is that a lot of people think consular services are akin to a get-out-jail card in monopoly. Unfortunately, they don't get you out of jail. At best, they are a phone a friend who doesn't want to talk to you service.
Separately, the other work they do in promoting the country has changed over the years because international communication has improved a lot.
