I have spent the last 4 weeks in England and can confirm that normal life has almost fully resumed here.
I am still seeing some people wearing masks around shops and on public transport and even a few in the open air, but I would guess it is an average of about 10% and nobody is trying to force anyone to wear them.
All businesses (well, the ones that have survived the lockdowns) are fully open and most have no capacity restrictions or social distancing guidelines in place.
Of course, there are still the entry restrictions, such as quarantine if unvaccinated and day 2 testing for all. My own experience with this was reasonably seamless in comparison with many other countries. I arrived on the ferry from Hook of Holland to Harwich and was not asked for my proof of vaccination or my Passenger Locator Form. It was more of a minor irritation than any real obstacle.
Of course, if you are unvaccinated, it is an entirely different story
If anyone is looking for a destination with a high level of day-to-day freedom, the UK is a reasonable option, at least at the moment.
