> unfortunately for me the DSL speed in my area is pretty bad due to being a few KMs from the exchange.

For VDSL the distance to an exchange shouldn't matter. The copper runs to a green box in the street, then another newer-looking green box nearby (or in some cases attached) with fibre in it takes the VDSL signal - and only old-school voice line conversations go to the exchange.

So definitely if previous ADSL speeds were poor it's time to check again. If you just meant that as shorthand then no worries, but I've run into way too many people who have the idea that all DSL is the same.
