Transferring your ISA to a better provider is one of the simplest ways to earn more on your savings — but doing it wrong can cost you your tax-free allowance. Here’s exactly how to do it right.
The Golden Rule of ISA Transfers
Never withdraw ISA money and redeposit it. If you take cash out of an ISA and pay it into a new one, HMRC treats the redeposit as a new contribution, counting against your annual £20,000 allowance. Any excess is no longer tax-free.
Always use the formal ISA transfer process — you instruct the new provider to request the funds from your old provider.
ISA Transfer Rules at a Glance
| Rule | Details |
|---|---|
| Can you transfer? | Yes — any ISA, any time |
| Who initiates? | The new provider |
| Does it use your allowance? | No |
| Can you change ISA type? | Yes (cash → S&S, S&S → cash, etc.) |
| Current year partial transfer | Not allowed — must transfer full current year amount |
| Previous year partial transfer | Allowed |
| Maximum transfer time (cash → cash) | 15 working days |
| Maximum transfer time (involving S&S) | 30 working days |
| Maximum transfer time (LISA) | 30 working days |
Types of ISA Transfer
Cash ISA to Cash ISA
The most common transfer — moving to a provider offering a better interest rate.
| Step | What happens |
|---|---|
| 1 | Open a new cash ISA with the new provider |
| 2 | Complete their ISA transfer form (online or paper) |
| 3 | New provider contacts old provider |
| 4 | Old provider sends the funds |
| 5 | Funds appear in new ISA — tax-free status preserved |
Timeline: Must complete within 15 working days.
Watch out for: Fixed-rate ISAs may charge an early closure penalty if you transfer before the term ends. Check the terms before transferring.
Cash ISA to Stocks and Shares ISA
You can move cash ISA savings into investments:
| Consideration | Details |
|---|---|
| Your money will be invested | Capital at risk — your ISA value can go down |
| Transfer form required | Same process — new provider initiates |
| In-specie transfer | Not applicable (cash has no holdings to transfer) |
| Best for | Long-term savings (5+ years) where you want growth potential |
Stocks and Shares ISA to Stocks and Shares ISA
Two options here:
| Transfer type | How it works | Best when |
|---|---|---|
| In-specie | Investments transfer as-is (no selling) | You want to keep your current holdings |
| Cash transfer | Old provider sells holdings, transfers cash, new provider reinvests | You want to change your investments anyway |
In-specie transfers avoid selling and rebuying, meaning no time out of the market. However, they only work if the new provider supports the same funds or shares.
Stocks and Shares ISA to Cash ISA
Your investments will be sold and the cash transferred. Consider:
| Factor | Impact |
|---|---|
| Selling investments | You may crystallise gains or losses |
| Time out of market | Gap between selling and transfer completing |
| Best for | Moving to safety if you need the money soon |
Lifetime ISA Transfers
LISA transfers follow the same principle but with additional considerations:
| Rule | Details |
|---|---|
| LISA to LISA | Full transfer allowed, 25% bonus history preserved |
| LISA to other ISA type | Triggers 25% withdrawal penalty (unless buying first home or aged 60+) |
| Other ISA to LISA | Counts against your £4,000 annual LISA limit |
| Timeline | Up to 30 working days |
Never transfer a LISA to a non-LISA unless you’re buying your first home or are over 60 — the 25% penalty wipes out the bonus and more.
Current Year vs Previous Year Transfers
This is the most misunderstood rule:
| Scenario | Can you do a partial transfer? | Full transfer? |
|---|---|---|
| This year’s ISA contributions only | No — must transfer all | Yes |
| Previous years’ ISA savings only | Yes — transfer any amount | Yes |
| Both current + previous years | Current year must be all-or-nothing; previous years can be partial | Yes |
Example: You have £50,000 from previous years and £8,000 contributed this year. You can transfer £30,000 of the previous years to a new provider (partial). But the £8,000 current year contribution must either stay put or transfer in full.
Step-by-Step Transfer Process
| Step | Action | Who does it |
|---|---|---|
| 1 | Choose your new ISA provider | You |
| 2 | Open an account with the new provider | You |
| 3 | Complete the ISA transfer form | You (via new provider) |
| 4 | Specify full or partial transfer (previous years only) | You |
| 5 | New provider contacts old provider | Automatic |
| 6 | Old provider verifies and sends funds | Old provider |
| 7 | New provider receives and allocates funds | New provider |
| 8 | Transfer complete — you receive confirmation | New provider |
You can usually track the transfer through your new provider’s app or website.
Transfer Timelines
| Transfer type | Maximum allowed | Typical actual time |
|---|---|---|
| Cash ISA → Cash ISA | 15 working days | 5–10 working days |
| Cash ISA → S&S ISA | 30 working days | 10–15 working days |
| S&S ISA → Cash ISA | 30 working days | 10–20 working days |
| S&S ISA → S&S ISA (cash) | 30 working days | 10–20 working days |
| S&S ISA → S&S ISA (in-specie) | 30 working days | 15–25 working days |
| LISA → LISA | 30 working days | 15–25 working days |
If your provider exceeds the maximum, you can complain to the Financial Ombudsman.
Common Transfer Mistakes
| Mistake | Consequence | How to avoid |
|---|---|---|
| Withdrawing and redepositing | Lose tax-free status; uses annual allowance | Always use formal transfer |
| Transferring fixed-rate ISA early | Early exit penalty (often 90–180 days’ interest) | Check terms first; wait for maturity |
| Transferring LISA to non-LISA | 25% withdrawal penalty | Only transfer LISA to another LISA |
| Trying partial current-year transfer | Transfer rejected or delayed | Transfer full current year amount |
| Not checking new provider accepts transfers | Application rejected | Confirm transfer-in policy before starting |
Costs to Watch For
| Fee type | Typical amount | Who charges |
|---|---|---|
| Exit fee (old provider) | Usually £0 | Some older providers charge £25–£50 |
| Entry fee (new provider) | Usually £0 | Rare |
| Early closure penalty (fixed-rate ISA) | 90–180 days’ interest | Common on fixed-rate cash ISAs |
| In-specie transfer fee | £0–£25 per holding | Some S&S ISA providers |
| LISA withdrawal penalty | 25% of amount withdrawn | HMRC (if transferring LISA to non-LISA) |
Most modern ISA providers charge nothing for transfers in or out.
When to Transfer Your ISA
| Situation | Should you transfer? |
|---|---|
| Better interest rate available elsewhere | Yes — compare rates annually |
| Lower platform fees for S&S ISA | Yes — fees compound over time |
| Fixed-rate ISA matured | Yes — rates often drop to a poor variable rate |
| Want to consolidate multiple ISAs | Yes — easier to manage |
| Current provider has poor app/service | Yes — good reason to switch |
| Small rate difference (<0.1%) | Probably not worth the hassle |
| Near the end of a fixed-rate term | Wait for maturity to avoid penalty |
