How do you get tickets for sky garden?

It just says no tickets available

Keep looking at the website regularly. They update their website and release tickets a few weeks in advance.

Alternatively book a restaurant.

It seems a bit of a(free) lottery on there.
I think usually they are available 2-3 weeks in advance but sometimes the system doesn’t seem to be updated frequently enough.
I managed (about 10 days ago) to get tickets for next week. I wonder if due to the upcoming half term the tickets are gone but they haven’t updated the system for the weeks after.
I tried before to get tickets and at first the dates weren’t showing at all and then a day or two later all gone!

We went the first week of January and didn't have tickets. They let us and loads of other people in after the ticketed people went through.
