The NHS are less strident about this these days (I haven't checked since my sons were born - they used to dissuade 5d scans entirely), but this guide gives a flavour of the caution they invoke around private scans:

Not sure if you actually read this document before posting it, but it is just a general cautionary statement, not about any specific test (and surely not about prenatal ultrasounds which have been proven safe).
All this says is effectively "all screening carries risks such as false results and overdiagnosis, so people should carefully assess benefits, harms, evidence, and costs before choosing private tests".
