## Quick answer

Transferring a cash ISA preserves tax-free status — your new provider arranges the move and must complete within 15 working days for cash ISAs under FCA rules.

Savers switch cash ISAs when bonus rates end or better deals appear. Never withdraw to your bank account yourself. This guide walks through the UK transfer process and partial moves.

## Key facts

- Cash ISA transfers must complete within 15 working days under FCA rules
- Use the new provider's transfer form — never withdraw cash to your current account yourself
- You can transfer all or part of previous years' ISAs while using this year's allowance elsewhere
- Transferring does not count as a new subscription — you can still pay into this year's ISA if allowance remains

## Starting a transfer

Apply to the receiving bank or building society with details of your existing ISA. They contact the old provider electronically or by post.

During transfer your money stays tax-free. Interest accrues according to old provider terms until completion.

## Partial transfers

You can leave some money in an old ISA and move the rest — useful if one account has a fixed bonus on part of the balance. Partial transfers let you keep a good rate on one portion while moving the rest.

This year's ISA subscription can stay in a stocks and shares ISA while older cash ISAs move — rules allow splitting years.

## When not to transfer

If your current ISA has an exit penalty or lost bonus that exceeds better rates elsewhere, waiting until the penalty ends may pay.

Fixed-rate cash ISAs may not allow partial withdrawal before term ends — check breakage charges. Breaking a fixed ISA early can cost many days of interest as a penalty.

## Frequently asked questions

### Can I transfer cash ISA to stocks and shares ISA?

Yes. The receiving stocks and shares provider completes the form — cash may be invested after arrival.

### Will I lose this year's allowance?

No. Transfers of previous subscriptions are separate from paying into the current year's £20,000 limit.

### What if the transfer is delayed?

Complain to the provider first, then the Financial Ombudsman Service if FCA timelines are breached.
