That sounds like a bargain, with planning fees based on size of shed. My memory's not as good as it used to be but over 465 m2 planning fees rise by something like £365 for each additional 75m2. So assuming another 20 foot bay on an 80 foot wide shed that should have added over £700 to the planning fee.I rang planning and they said to do right I should apply for "amended application" but they were happy to leave me alone unless they got a complaint which they did due to an annoying neighbour so £80 later and my amended application and I'm squeaky clean

Sorry, just realised you're not the OP, don't know what size shed he's building.
