I think there are Building Research Establishment guidelines for daylight impact which you might want to google for. In Scotland you can request a Daylight Impact Analysis so you may be able to request the same in your area. Without such an analysis being requested and the results failing the guidelines you won't have a leg to stand on, subjective analysis is just no good. Also, I don't think the demands are that onerous so you probably won't get far in any case, sorry.
