"Deaths that occur due to organ failure that may be related to Covid-19? No, don't mention them. Deaths outside of hospital, care homes etc - can't be sure leave them off the stats."
Overall population deaths are harder to hide and you can compare those to the 5-20 year averages.

It's MUCH harder to hide this kind of peak - and the ONS numbers trace a curve in the UK that shows that the "above normal" death figure was in excess of 40,000 people when the government was claiming 10,000 Covid fatalities (that was the most recent release, these things are necessarily a few days delayed)
