Fwiw, Germany is also taking a big chunk ontop.
If you add taxes taken from your wage and VAT, forced social security payments etc all up, you'll end with a rough taxation of ~50% in UK. Of you do the same in Germany you end up over 60%, often nearing 70% unless you're a single income household with kids (they lower the tax burden a lot through deductions. Obviously still expensive, but your social contributions go down a lot.)
