I wanted the change of use and asked my landlord for the permission, he said yes so I paid the fee to my local council and the application went on the system. Then the landlord realised he needed he had to have the freeholders permission and when he asked them they said they wanted the £6000. If I'd been aware that someone wanted £6000 just to change a unit to A3 with no other alterations I very much doubt I'd still be there. I've paid my planning costs with no arguing. My lease states I need permission from my landlord to change planning use and to go through my local council. The landlord named on my lease is who I asked as I don't even know the freeholder and permission was given, therefore I followed my lease to the letter. Not sure why you think I'm trying to avoid planning costs? I've dealt with my local council on that plenty of times and it's nothing new to me. Having a £6000 bill thrown at me almost a month after planning has gone into the system is a new one for me though.
