@Crosswithlifeatm "Excess deaths" are the extra deaths compared to the historical average for the same period in previous years
As pp have said, Germany has a much larger population than the UK and hence a larger annual number of deaths
So what matters on your charts are the sizes of the area of the red parts (COVID) and blue (Non-COVID)
which are much larger for the Uk than for Germany or most other European countries
btw, the excess "non-COVID" deaths dropped as COVID deaths dropped, so COVID is likely to have been a contributory factor to the blue area too.
The FInancial Times has calculated the excess deaths for the UK as 67,000 - a 49% increase over the historical average
and Germany's as about 9,000 - about 6% above the historical average
Their graphs make it easier to understand:
