The missing fountain

I have been trying to find this fountain for some while. It is Grade II listed. The address given on the British Listed Buildings site and the location pin there is completely wrong . Here is the listing if you are interested. The address given is 156 London Road. If you go to the pin on the website map you are at 156 Tonbridge Road and there is no sign of the fountain. I went to 156 London Rd and its not there either.
I have today found it in a side road called Mount Pleasant.  There is a facility to tell the LIsted Buildings people that the location on their website is wrong. Can I be bothered?
