All of the above is fine and dandy but.... If you are being offered another licence, then take it. The cost will be negligible and the potential benefit unknown but possibly worth having in these uncertain times.
For clarity, and as Whopity says, you are being offered an ICAO-compliant UK PPL, not an NPPL. ICAO-compliant licences of various flavours are valuable things and you can never have too many, especially in these uncertain times.
