Thanks for your email. Yes, I'm pretty sure that's how the locations 
have been derived in most cases and the comparison tool coalesces nearby 
establishments into a single marker position and displays a list in the 
popup for that reason.

If the FSA aren't able to solve the problem, I may add another stage of 
processing to the comparison tool and look up postcode centroids.
