Not sure you will need type approval. Registering as Invalid Carriage puts it in a rather vague grey area.

In percentage terms how much more efficient would you say a brushless dc motor is compared to a brushed one?
Also why are brushless not used more often in mob equipment?
Also didn't you try a pair of brushless when you were building your BM3 but couldn't get them to work properly with the Roboteq. Sorry in advance if I've got that all about cock.
Do the high tech lithium powered fold up scooters use brushless? Is it likewise for the lithium power add ons for manual chairs?
None of fold up scooters or add one are cheap. Several £1000s usually.
BM can do more details, but his first effort at a fancy 'do-everything' chair was an Invacare that used their 'Gearless-Brushless' motors - he found that they would draw several hundred amps trying to do zero-speed turns on grass or carpet.

I also had an EW-36 for 2 years and therefore I speak from my owne experience. In Germany, they called themselves „Engel 1000“. My Scooter has 60V - 1000W and a drum brake that does not brake. As the scooter has no electronic brakes, it gets faster and faster downhill. Top speed are real 25 Km/h and the acceleration is good. Unfortunately, the controller is kept very simple. It has no security features, such as those found in wheelchairs. Therefore, the scooter often jerky and goes up with his front. Also, it tilts slightly to one side because the controller does not slow down in turns.
Qualitatively, the scooter is badly processed. (China) The tires get after a short life Stands, so that the mobile has an imbalance. They also leave quickly. In Germany you get it already well under 2000,- Euro and in every shop.
(Sorry, it was Google Translation, not me)

what makes this not comply in the UK?

Thanks for that your real-world experience is really interesting
Do you feel they're not safe to use in a shopping centre? I would never get one, top speed isn't everything. Safety of the rider and pedestrians is more important.

I bet them large diameter wheels give a very comfortable ride.

i have also dropped the seat height by 75mm (3 inch) this makes a HUGE difference in stability
