Things may be different in the UK (after all, "traceability" is short 
for "legal traceability," and the law of legal metrology may be 
different there), but in the US one of the necessary criteria for 
traceability is "demonstrated competence."  There may be a 
philosophical question whether "competence" can be "demonstrated" in 
some manner other than by accreditation, but there is no practical 
question.  Universally (in the US), this is done by becoming 
accredited to the relevant ISO/IEC standard.

Best regards,
