There's explanatory notes on the RSGB website, including a spread sheet
you can fill in for your own situation and equipment. The spread sheet
can be saved in pdf format as a record.

In most cases showing compliance shouldn't be a problem.

Can I stick DANGER RF signs up facing the neighbours...would that go
down well?....OFCON should be sorting out the mess they have made of
amateur radio before starting box ticking exercises like this
one.....but it could be worse it only applies above 10Mc/s ....

The main political driver is probably the anti-cell tower lobby. It
probably particularly badly affects amateurs in that many probably
haven't been fulfilling their duty to design for safety before, so are
caught out when concrete figures are set on safe limits.
Amateur radio has been going for over a century. Some of the
installations have been pretty 'hairy' (especially in the early days),
but as far as I know, there have been absolutely NO reports whatsoever
of anyone being adversely affected by the effects of RF radiation from amateur stations.
At the risk of being considered irresponsible, I'm tempted to suggest
that it's a bit late in the day to start introducing safety precautions
when there is no evidence that we need them!

I wholeheartedly agree. However, the chance of these new >restrictions/impositions being retracted, or even moderated, is, I
think, from vanishingly-small to nil.
I pity the amateurs who know nothing of computers, and have been
happily and harmlessly operating on HF for the past half-century, using
100W of SSB and/or CW to a G5RV or a longwire at twenty feet AGL; how
will they fare, I wonder?

From what I have read elsewhere, OFCOM have essentially been obliged to enforce Public Health England's advice.

From what I have read elsewhere, OFCOM have essentially been obliged to enforce Public Health England's advice. OFCOM's document 'Guidance on
EMF Compliance and Enforcement' says "PHE's main advice is that EMF
exposure should comply with the Guidelines published by the
International Commission for Non-Ionizing Radiation Protection (ICNIRP)".
While OFCOM are incorporating the safety rules as a licence requirement,
it's interesting that document makes frequent use of the words 'advice', 'guidelines' and 'guidance'. But faced with three such august bodies, I
guess there will be few who will be bold enough and qualified enough to challenge the validity of the safety requirements.

Well in that case they can't have re-validated their licence in the past
five years and it will technically be invalid although not revoked by
OFCOM.
You can make an initial application on paper but you must set up an
on-line account to re-validate your licence.
ISTR that some other countries have less-restrictive limits on EMF for amateur stations; parity with them would not be an unreasonable request,
I'd have thought.

The Americans have had to comply with numerical limits that are similar
to, and sometimes more strict than, ICNIRP 2020, since 1997. The main difference is that there is a presumption of compliance below 50 W PEP,
so the calculations are not expected below that level, rather than below
10 W EIRP. On the other hand our 10W EIRP limit seems to be an absolute
get out, whereas the 50W PEP limit only removes the need to do
calculations; if the presumption of compliance proves invalid, it looks
like a US amateur would still be in trouble.
Given 100W PEP is a fairly common transceiver rating, I think a lot of
people would have to do the calculations, even on US rules.
In any case, I cannot see why something that is considered unsafe for commercial users, who typically have professionally installed equipment, could be ruled safe for amateur users. These rules are being applied
for all users, not just amateurs.

Is the whole exercise merely a paper tiger?
I wonder whether there might be room for a dB or two of easement in our limits, as AIUI the official separation distance calculator is said to
be very conservative. It could make the difference between being able to continue to operate or having to close down.

Most UK legislation is. It generally assumes that people are law
abiding, and actual enforcement has been underfunded in many areas of life.
I'm already (I believe) in breach of my licence as I haven't printed it
off. I just have a .pdf on the 'puter. Also when I built the station
many years ago I did so with emf in mind and I know I'm well within the
new regs. If any one comes to inspect my station I'll happily lend them
a tape measure and challenge them to prove I now exceed the regs. Then
I'll put the .pdfs of their calcs in the same directory as my licence. Basically I claim "they" need to prove I'm not compliant rather than I
have to prove I am every time I key up. (guilty until proved innocent)!

I don't see anything in the licence that says that it has to be printed, merely "kept" at the main station address.
The new regulation put the onus on you to prove that you meet the
required levels, and to document and keep a record of such.

OTOH, if by any mischance OFCOM did find out an amateur could face the local press accusing them of thoughtlessly frying the neighbours and passers-by by not checking. Could create local unpopularity. Would it be an offence under the Wireless Telegraphy Act, or successor legislation?

I fully realise that most ordinary amateurs are producing RF fields near their
homes several orders of magnitude too small to do any harm. I'm just saying that if the newspapers got hold of the fact that an amateur had failed to do a
compulsory risk assessment that it could make very bad publicity, for the amateur concerned and for amateur radio in general. They would spin it as ignoring terrible dangers!
The main difference is that there is a presumption of compliance below
50 W PEP, so the calculations are not expected below that level, rather
than below 10 W EIRP
