In the entire UK, 8,974 deaths attributed directly to alcohol in the whole year of 2020 (18.6% higher than in 2019). Most are not acute "drinking yourself to death" but rather alcohol-related liver disease. Scotland and Northern Ireland fare worse than the other countries.

For London specifically, in 2020 it was ~800 deaths, or about 2.2 per day on average.
