Since April 2024 it's all been simplified.

Simplified to what? Have you got a link?

It's covered by regulation 5DDB if you want Google it

If you want to use the flaxible aspect of your ISA you need to 1. Replace the withdrawn money into the same account that you withdrew it from and 2. Replace it in the same tax year that you withdrew it. Not much else to say.

Related question - Could I instead transfer the full balance to a new provider, and then withdraw just this year’s element as a flexible part? And then pay that back in later? I guess I’m asking whether this year’s balance remains flexible if you transfer it to another provider?

You can withdraw/replace any or all of it. Makes no difference whether it’s old money or new.

I’m confused! I thought you could only replace this year’s allowance with a flexible ISA? Is it possible to withdraw and replace previous year’s allowances too??

in my case I have £80k in an ISA. I have paid in nearly £20k of that this tax year. How much of that is flexible then? Just this year’s £20k? Or the entire £80k?

If you have £80k in a flexible ISA, you can withdraw £80k and as long as you return it to the same ISA and in the same tax year, you can put £80k back without using any more of your ISA allowance.
