It might be behind a paywall, but here's a bit of a rundown:

The article is written by a Dr. John Lee, a pathologist and NHS consultant. He says COVID-19 has been added to the UK's list of notifiable diseases. This may be for good reason, but it means that COVID-19 deaths are being reported differently than deaths from flu or other common infections not on the "notifiable disease" list.

From the article:

"Making COVID-19 notifiable might give the appearance of it causing increasing numbers of deaths, whether this is true or not. It might appear far more of a killer than flu, simply because of the way deaths are recorded. If we take drastic measures to reduce the incidence of COVID-19, it follows that the deaths will also go down. We risk being convinced that we have averted something that was never really going to be as severe as we feared. This unusual way of reporting COVID-19 deaths explains the clear finding that most of its victims have underlying conditions — and would normally be susceptible to other seasonal viruses, which are virtually never recorded as a specific cause of death."
