Where was Lovejoy Filmed?
The reason that there is little or no information on the IMDB website for the filming locations for the TV series Lovejoy is that the production team did not disclose this information in the credits of the episodes. IMDB rely on the input from viewers and often they are not local to the area and as such have no way of recognising places that they see.
In addition, some of the information that you see on the IMDB website is just wrong. For example, while the last episode of Lovejoy, "Last Tango in Lavenham", was filmed close to Lavenham but I have yet to identify any locations. The church where the episode was filmed is that of St. Mary Belchamp Walter and is in line-sight of Felsham Hall. You can see this from the aerial shots from the Helicopter.
