Is there any electric scooter shops in London  that fix any type of electric scooters?

If there aren't then there should be.  

Yes. At least 8.  Open Now, Monday , 19 April;  at   12 PM BST, not brand-specific, at least, by their names. Perhaps 12 if you inquire (enquire)::

  IDK which End of London UR at.  Use the telly to reduce bus fares.  If U have a bad scooter; in my experience, it's battery(s) or controller. Some pulse-width-modulated controllers cost  too much to be worth it.  An unrepairable, epoxy Slab. Unless for  handicapped,  they Really sock it to ya on medical eqt.

 ref: Just got out of wheelchair/walker after my "mishap", used to fix switching power supplies professionally which utilize PWM tech.

  Exo; again, not  an "answer"  consistent with YA  philosophy. Like saying:" yes", it's reason the 15 character minimum enacted..

Call them to see.

Google is your friend.
