I'm sorry, but you are incorrect.
YOU CAN SHOOT APPROACHES TO 200ft (300ft NP) WITH AN IMC RATING.
There is an ADVISORY for an IMC holder to add extra height, but IT IS NOT LAW. So many people misunderstand this. Please get your facts right. It's all in print in the AIP/ANO. I also have it in writing from the CAA.

Shooting precision approaches to <300ft perfectly legally with an IMC rating since 2006
3.3.2.1 Pilots with a valid Instrument Meteorological Conditions (IMC) Rating are recommended to add 200 ft to the minimum
applicable DH/MDH, but with absolute minima of 500 ft for a precision approach and 600 ft for a non-precision approach. The UK IMC
Rating may not be valid outside UK territorial airspace, therefore IMC Rated pilots should check the validity of their rating for the State
in which they intend to fly. If the rating is not valid pilots must comply with the basic licence privileges, subject to the regulations of that
State.
