I've just visited Upnor Castle and thought I'd put down a few notes on its accessibility.
Arrival: as the English Heritage book warns, access is difficult. There is one disabled space, and you need to phone up to reserve it. The right-angle turn into the castle is tight, ensure you are happy with bumping up on curbs and shunting to-and-fro. Exit is by reversing out of the castle, shunting around at the gate, then reversing all the way up the hill.
Scooter access: there is a gravel path up to the castle which should present no problems for scooters or wheelchairs. If you wander around the grass beware of rabbit holes, stick your rear wheel down one and it spins uselessly!

To gain access to the courtyard there are three full size steps. A wheel chair with a strong carer might manage them, otherwise it is get out and carry your chair/scooter down. There is also a significant cill on the inside of the gatehouse, a large wheel wheelchair might manage it, but a small wheel scooter will need lifting over.
General access: there is wheeled access all around the courtyard, but if you have some mobility it is best to enter the two towers and central gunpowder store on foot. There is a decent exhibition about the Dutch raid on the ground floor of the gunpowder store. There are no lifts, so access to other floors and the riverside walkway is by foot only. I didn't attempt it this visit, but from past able-bodied visits the central building is well worth exploring if you are capable,
but some of the steps are steep/uneven/circular so care is required.
Suggestion: English Heritage and/or Medway Council (the property is in joint management of some description) might consider a wooden ramp down the three steps. No damage or alteration to the fabric would be required. Likewise some easing of the cill by a short ramp would help small wheeled scooters get in and out. The costs of both should be insignificant.
Finally: Thanks to the most helpful and friendly staff. I intentionally visited off season so that they would be less busy (and to get parking) and was well repaid. I hope this is of help to other visitors.
