I have to think that the very recent turnaround for "test and trace" more than doubling their results has something to do with QMC HealthID running alongside the NHS systems. They buried the following at the bottom of the article.

 A DHSC spokesperson said turnaround times had been steadily improving over recent weeks, and the latest performance figures showed that tracing had dramatically improved, now reaching 85.7% of contacts.
“As the Covid-19 vaccination programme is rolled out, we are determined to ensure that NHS test and trace plays an even more effective role in stopping the spread of the virus.”
• The headline on this article was corrected on 11 December 2020. The government’s test-and-trace programme is only used in England not the whole of the UK; the devolved nations have their own systems.
