Ive ignored their figures in this all along, and used my own from the office of National Statistics.
They helpfully publish deaths this year every week, week by week, compared the average of that week over the last 5 years. Gives a decent insight into the real situation

There is also some Covid data in there but I ignore it in favour of the above, as they are absolute figures, not depending if someone thought covid was somehow involved.
