Disregard the class rating conditions in art 10.
Licence conversion does not require surrendering the original licence. The process will simply lead to a second licence independent of the original.
The form SRG2142 should be filed with UK CAA to verify your EASA licence and exam passes before applying for a UK licence.
The passes should count towards the UK FRTOL. Your ATO can organise an RT practical test if needed. The UK FRTOL privileges are normally endorsed on the flight crew licence although a separate licence document can be issued. Details at
https://www.caa.co.uk/General-aviati...rator-licence/
The SRG2142 verification is valid for the issue of a UK licence for 6 months:
Stage 3
Once we receive this verification it will be added to your records and
it will remain valid for 6 months from the date of issue. You can then
apply for the desired licensing service on the appropriate application
form(s).

The IAA may require your permission before sharing your licence details with the UK CAA.
Your knowledge exam passes will be accepted for the issue of a UK Part-FCL CPL or IR until the end of 2022. The validity periods specified in point (c) of FCL.025 should apply.
The CAA will continue to recognise EASA Theoretical Knowledge
certificates that were current (and within their validity dates) on 31
December 2020 for up to two years toward satisfying the requirements
for the issue of a UK CAA licence. Any exams completed under the
auspices of an EASA Member State’s competent authority after 31
December 2020 will not be recognised toward meeting the requirements
for the issue of a UK CAA licence.

It's unclear whether EASA ATPL exam passes will count for the issue of a UK Part-FCL PPL. The language proficiency demonstration required by point (2)(e) in art 9, quoted in post 7 above, can be done during the PPL/CPL skill test if you are at ICAO Level 6 (native speaker).
Language assessment during a skill test
You will probably be tested on your language skills during your skill
test and your level of ability will be recorded in the examiner’s
report form. As long as you are assessed as a Level 6 speaker, the
examiner’s report will count as proof of your language proficiency and
you will not need to send us anything else.
Only UK-registered examiners can assess your English language
proficiency during a skill test. When they do this, they can either
mark you as a Level 6 (an expert speaker) or recommend you are
assessed by a language school. They are not able to issue any other
Level.

The guidance on the UK CAA webpage for commercial pilots, quoted in post 4 above, isn't terribly clear. In the context of an EASA licence issued after 31 Dec 2020 the stated policy is that "
recognition will be given to any ... flight training conducted at an EASA ATO prior to 31 December 2022 and skill tests conducted by EASA examiners during this period" but the section which follows states that "
training undertaken in the European system before 31 December 2020 will be accepted when issuing a UK licence". Further down the page the guidance is that: "
After 31 December 2022, neither training in the EU system nor exams taken after 31 December 2020 will be accepted in the award of a UK licence."
Were the Part-FCL CPL and IR training courses done in the UK?
