Can I withdraw and replace ISA money UK?

Only if your ISA is flexible. With a flexible ISA you can withdraw money and replace it in the same tax year without it counting again towards your £20,000 allowance. Non-flexible ISAs treat any replacement as a fresh subscription, eating into your annual limit.

Full answer

Flexibility is an optional feature — providers decide whether to offer it, and the same product type can be flexible at one bank and not at another. Cash ISAs and innovative finance ISAs may be flexible; Lifetime ISAs and Junior ISAs cannot. Stocks and shares ISAs can be flexible too, but many platforms (especially low-cost ones) do not enable it. Worked example: in a flexible cash ISA you have already paid in £20,000 this tax year. You withdraw £5,000 in October. You can put that £5,000 back any time before 5 April without breaching the cap. In a non-flexible ISA the same withdrawal cannot be replaced — paying it back in would breach the £20,000 limit. Important rules: replacement must go to the same ISA you withdrew from (not transferred to a new one mid-year); the rule resets each tax year — unspent withdrawals do not roll over; and transfers between providers do not count as withdrawals. Always check the provider terms for the word ‘flexible’.
