How to Transfer an ISA

What is an ISA transfer?

ISA transfer vs withdrawal

An ISA transfer is the official process of moving money from one ISA provider to another without the funds ever leaving the ISA wrapper. The transfer is handled directly between the providers, and savings or investments remain tax-free throughout.

A withdrawal, by contrast, is where money leaves the ISA wrapper altogether. Once withdrawn, the money loses its tax-free protection. If you later re-deposit the withdrawn funds back into an ISA, it will usually count as a new contribution and use your annual ISA allowance.

Common reasons people transfer ISAs

As personal circumstances, market conditions or financial goals change, this may necessitate a ransfer to an ISA that’s better suited to their own individual situation. Common reasons why people might want to move funds to a different ISA include:

• Better interest rates or fees: There may be a provider offering higher returns on cash, or reduced platform and fund charges for investments
• Wider investment choice: Access to a broader range of funds, shares, ETFs, or ready-made portfolios that better suit your goals or risk appetite
• Consolidation: You have many ISAs currently open with small denominations within the accounts, or accounts that are not active, and you want to merge them into one ISA
• Moving between Cash and Stocks & Shares ISAs: Switching to cash for short-term certainty, or to a Stocks & Shares ISA for long-term growth potential, whilst keeping funds tax-free through the official transfer process

An ISA transfer gives you the flexibility to move funds to a more appropriate ISA type without sacrificing the tax-free status of the money in the account.

Does transferring an ISA affect your allowance?

Transfers do NOT use your ISA allowance

Transferring an ISA does not affect your annual ISA allowance, as it merely moves existing investments or ISA savings to another provider or account and is not considered a new contribution.

What does use your allowance

Your ISA allowance is only affected when money leaves the ISA wrapper and is later repaid as a new contribution. This could happen if people try to move or reuse ISA savings without using the official transfer process. Actions that can impact your allowance include:

• Manual withdrawals: If you withdraw money from an ISA into your bank account, it loses its tax-free status. Paying it back into an ISA later counts as a brand new contribution and uses up your allowance for that tax year.
• Closing an ISA and reinvesting: Closing an ISA and then opening a new one to redeposit the funds will be treated as a withdrawal. Even if the money was originally built up over many years, reinvesting it counts towards your annual limit.

Simple worked example

Let’s consider an example of how your money can be correctly transferred between ISAs, as well as an example of the wrong way to move your ISA savings

Correct transfer

• John has £40,000 in a Cash ISA, which he has built up over several years. He then finds a new provider who is offering a higher rate and decides to complete an official ISA transfer form with the new provider. The money is subsequently moved directly between the two providers, never entering John’s bank account.

Result

• His full £40,000 remains tax-free, and his current ISA allowance is untouched.

Incorrect transfer

• John withdraws £40,000 from his Cash ISA into his bank account, and later deposits those funds into another ISA himself.

Result

• When the £40,000 moves from his bank account into the new ISA it is treated as a new contribution and affects his ISA allowance. In addition to using his ISA allowance unnecessarily, because the £40,000 deposit exceeds the £20,000 annual ISA allowance, he would have to spread his transfers over 2 years as a provider would not allow a £40,000 contribution in a single year.

How long does an ISA transfer take?

ISA transfer speeds vary by account type.

Cash ISA transfers

Cash ISA transfers are usually the quickest and most predictable. In most cases, a Cash ISA transfer takes around 5 business days for an internal transfer with the same provider, and up to 15 days for an external transfer from the point your new provider receives a correctly completed transfer form.

Stocks & Shares ISA transfers

Stocks & Shares ISAs have a longer transfer time because investments usually have to be sold before the move can be completed (unless your ISA is being transferred ‘in specie’, which means your stocks, shares, and funds can be transferred from one provider to another without selling them first).

When investments are sold, trades must settle before cash can be transferred, and settlement times vary by asset type and can add several days to the overall process.

If your Stocks and Shares ISA isn’t being transferred in-specie, then you should expect a wait of up to 30 days before the transfer is fully completed, while in-specie transfers might take slightly longer.

Common reasons for delays

While most ISA transfers complete within the expected timeframe, delays are not unusual, especially for more complex accounts. Understanding the common causes can help set realistic expectations.

Some standard reasons for transfer delays include:

• Incomplete or incorrect forms: Missing details, mismatched account information, or unclear transfer instructions can pause the process until the provider receives clarification.
• Fixed-term restrictions: Fixed-rate Cash ISAs or notice accounts may prevent transfers until the term ends or require notice to be served before funds can be released.
• In-specie (re-registration) transfers: Moving investments without selling them is more complex than transferring cash. Some assets take longer to re-register, and not all providers support in-specie transfers for every fund or share.

Although delays can be frustrating, the official transfer process keeps your funds within the ISA system and preserves the funds' tax-free status.

Full vs partial ISA transfers

Some ISA providers will allow you to transfer part of your existing ISA to them, while others might only allow a full transfer.

Full transfers

A full ISA transfer moves the entire balance of your existing ISA to the new provider. Once completed, the old ISA is usually closed. Full transfers are typically done when you are switching to a provider with better rates or lower fees, want to consolidate ISAs into a single account, or no longer need the features of your existing ISA.

Partial transfers

A partial transfer occurs when only part of your ISA balance is moved to a new provider while leaving the rest in the original account. Whether this is possible depends on the provider and the type of ISA.

Partial transfers are useful if you want to test a new provider, access different investments, or avoid disrupting an existing fixed-rate or long-term savings strategy.

Key limitations

While partial transfers can offer flexibility to test new account features and other benefits, there are some restrictions to be aware of, particularly for fixed-rate ISAs.

Key limitations might include:

• Fixed-rate ISA restrictions: Providers often impose limits on transfers into fixed-rate ISAs. Full balance transfers are typically the only transfers allowed at the end of the fixed-term agreement. Partial transfers may be blocked altogether and incur penalties.
• Current year subscriptions: If you’ve paid into an ISA during the current tax year, some providers require you to transfer all of the year’s contributions together. Splitting current-year subscriptions across multiple providers is usually not allowed. 

Transferring different types of ISA

Transferring a Cash ISA

Transferring a Cash ISA is generally straightforward and follows a standard provider-to-provider process. Because the funds are already held as cash, there’s no need to sell or re-register investments, which helps keep transfer times relatively short. It’s worth noting that interest is typically paid by your existing provider until the transfer process is completed.

Transferring a Stocks & Shares ISA

When transferring a Stocks & Shares ISA, you might be given a choice between moving your investments as cash or transferring them in-specie, meaning the investments are re-registered without selling them. The right option depends on cost, timing, and your attitude to market risk.

With a cash transfer, the investments are sold, and the proceeds are transferred to the new provider in cash. This is usually a fast and simple process, but leaves you exposed to out-of-market risk since your money isn’t invested while the transfer completes, meaning you could miss gains if the markets rise during the transfer process.

However, this does have the benefit of shielding the investments from potential losses should the market dip during the transfer.

Transferring a Lifetime ISA

Transferring a Lifetime ISA (LISA) must be handled with care, as the rules for transfers can be stricter than for other ISA types. A manual withdrawal from a LISA triggers a withdrawal penalty, even if you intend to reinvest the money elsewhere. This penalty can leave you with less than you originally contributed, as it claws back the government bonus and adds an additional charge.

It’s critical to use the official transfer process when moving funds from one LISA to another, and it’s important to note that a transfer from a LISA to another type of ISA will be treated as a withdrawal and will be subject to a 25% withdrawal charge.

Transferring a Junior ISA

A parent or guardian can transfer between the providers of one Junior ISA (JISA) and another, but they can’t close the account or withdraw the funds manually. When the child turns 18, the JISA automatically converts into an adult ISA. At this point, the child gains full control of the account and can choose whether to keep it, transfer it, or start making withdrawals.

Flexible ISAs and transfers

How flexible ISAs normally work

A flexible ISA allows you to withdraw money and replace it within the same tax year without using up any additional ISA allowance, provided you replace the funds before the end of the same tax year.

What happens on transfer

Transferring a flexible ISA works in the same way as any other standard ISA transfer, and you can choose whether to move some or all of the funds. However, if you’ve created a flexible allowance in the ISA that you want to transfer, that flexibility only applies to that specific ISA account. This means that should you decide to transfer the original flexible ISA to another provider, you will lose the flexible ISA allowance you initially created.

It is also important to note that transferring the flexible ISA to a new provider may sometimes mean giving up the account's flexible status entirely. 

Why this matters

Losing the flexible ISA status can have real allowance planning consequences, particularly if you move money in and out of your ISA on a regular basis. Whether an ISA account allows you to retain its flexible status depends on the provider. If flexibility is important to you, then it’s crucial to check the rules on transferring to your chosen provider.

Common ISA transfer mistakes to avoid

Whilst ISA transfers are a relatively simple process, there are a few common ISA transfer mistakes to avoid:

• Withdrawing instead of transferring: Taking money out of an ISA and paying it back in later breaks the ISA wrapper for those funds while also using up additional ISA allowance unnecessarily.
• Ignoring fixed-term penalties: Fixed-rate ISAs often apply interest penalties for early exit, which can wipe out the benefit of a higher rate elsewhere.
• Losing flexible allowance unintentionally: Flexible ISAs don’t carry their replacement rights across to a new provider.
• Transferring during bonus-rate periods: Some ISAs pay temporary bonus rates that are clawed back if you leave early. Because of this, moving mid-bonus can result in a lower overall return than expected.
• Assuming all providers allow partial transfers: Partial transfers are often restricted, especially for fixed-rate ISAs and current-year subscriptions. Always confirm the rules before starting

Should you transfer an ISA or open a new one?

When transferring makes sense

Transferring an ISA is a good option when your main goal is benefiting from features offered by a different ISA while protecting your existing tax-free savings.

Transferring is also suitable if you’re keen to consolidate your ISAs into a single account with one provider.

When opening a new ISA may be fine

Opening a new ISA might be a suitable option if you have additional ISA allowance you haven’t used and are happy to manage both ISAs side by side.

What protection applies during an ISA transfer?

FSCS protection

The Financial Services Compensation Scheme (FSCS) covers an eligible person, per financial institution, up to £120,000 for Cash ISAs and up to £85,000 for Stocks and Shares ISAs. This protection also applies during the transfer process, ensuring that your funds are covered at all times with the ISA.

H3: What FSCS does not cover

FSCS protection is a vital safeguard, but it does come with some limitations.

Firstly, it does not cover provider rate changes, nor does it cover market losses associated with investments in Stocks & Shares ISAs.

The FSCS does enable protection during the transfer, but it does not safeguard against administrative delays.
