To be brutally honest, I have had nothing but trouble with them since I applied for my FAC, when I got my SGC they where great to deal with (albeit a bit slow). This variation has been an uphill battle, they contacted the one of the wrong landowners about my permission and then after I corrected their mistake, refused to add the other permission, and being TVP they still mandate closed licenses for five years, so I have to go through the whole thing again for the remaining permission!!!
I have to agree that their online system is quite nice and a breath of fresh air compared to other forces application systems though, that and most of the time you can actually get in contact with someone.
