Currently in the Coverage Map you can only search using the postcode. I think that two other possibilities would be useful
1: Search by town to find a general area quickly
2: Obtain details by location on a map by clicking on the location
The above would for instance enable you to quickly locate a general area (eg a town) and then look for details at various locations in the area by simply clicking on them (you may not know the postcode of a particular street).
I hope the above suggestion is helpful.
