I have a blocked toilet - the bowl drains very slowly, suggesting a 90 -
95%
blockage.

Pumping up and down repeatedly with a large plunger has made a big
improvement
- estimated blockage now down to 10%

The blockage is either
in the u bend. Shoving your hand down there with a short length of hose
should eliminate that.
or outside in the vertical soil pipe. Unlikely, but there should be a
removable plate for rodding,
or outside and below ground (most likely) where you should have a manhole
cover. I'd start with the latter and work backwards.
Removing the bowl is pretty drastic for such an everyday event.
Chemicals are usually a waste of time. You need some kind of physical impact
to shift obstructions.
