ISA transfer rules explained

How do ISA transfers work?

Investing in an ISA is a great way of growing your savings free of income tax and capital gains tax. However, how you invest the money within the ISA wrapper can have a significant impact on your long-term returns.

If your savings are held in a cash ISA then there is a wide choice of providers with a variety of interest rates on offer and it makes sense to shop around for the best ISA transfer rate deal. If your savings are in stock market-linked investments (via a Stocks and Shares ISA), there are now many providers offering a range of investment options to make the management of your Stocks and Shares ISA simple and cost-effective.

As the investment market is continually developing, your original choice of ISA provider, for either your cash ISA or Stocks and Shares ISA, may no longer be the best choice to meet your long term saving or investing goals. It may be that the interest rate on your cash ISA is no longer competitive (you can check our best buy tables), or your Stocks and Shares ISA provider doesn't offer the tools, research or fund range that could help improve your investment returns. If this is the case then it may make sense to transfer your ISA to another provider. Remember, inertia may increase the ISA provider's profits while diminishing your investment returns.

What are the ISA transfer rules?

Below is a roundup of the cash ISA transfer rules as well as the transfer rules for a Stocks and Shares ISA:

• You can transfer all or part of the funds in your ISA from one provider to another at any time, regardless of whether you made the deposits in the 2025/2026 financial year or a previous year (restrictions apply for Lifetime ISAs and Junior ISAs)
• As long as you make the ISA transfer through the proper channels, your £20,000 annual tax-free allowance will not be impacted
• ISA transfers can be made from a cash ISA to a Stocks and Shares ISA and vice versa and savings from previous years can be split between a cash ISA and a Stocks and Shares ISA
• Under current cash ISA transfer rules, providers must allow ISA transfers out of a cash ISA but are under no obligation to allow transfers in
• Look out for any ISA transfer penalties from your existing ISA provider, particularly if you are transferring from a fixed cash ISA before the end of the fixed term
• In addition, some Stocks and Shares ISA platforms apply transfer fees per ISA fund that you transfer. Make sure you check whether your investment platform applies these charges. If they do then you may be able to mitigate them by consolidating the number of ISA investment funds that you have ahead of any ISA transfer
• Aside from the nuances stated above, there is no ISA transfer limit and you can transfer an ISA at any time

How long do ISA transfers take?

There is no ISA transfer time limit but if you are transferring a cash ISA to another cash ISA then this process should take no more than 15 days, if it takes longer then under cash ISA transfer rules you should be compensated for loss of interest. If you are transferring in to or out of a Stocks and Shares ISA then the process should take no more than 30 days. If you are transferring from a Stocks and Shares ISA you need to be aware that there may be a charge for selling your investments with your current provider prior to the transfer (if an in specie ISA transfer is not possible)

If you feel your ISA transfer is taking too long then you can complain to your existing ISA provider and then ultimately to the Financial Ombudsman Service

How to transfer an ISA

An ISA transfer is a simple process:

• If you are looking to transfer an ISA, then firstly you should do your research to make sure your new provider will accept ISA transfers and give you the best ISA transfer rate or the most comprehensive investment service you require
• If you are looking to transfer into a Stocks and Shares ISA then read our article ‘The best Stocks and Shares ISAs‘
• Check our comprehensive guide to the Best easy access ISA rates if want to transfer into a cash ISA
• Once you have decided on your new provider then contact them to open an account and complete an ISA transfer form
• Once the account is opened and the ISA transfer forms are completed your new provider will contact your current provider to complete the transfer

Never withdraw money from an ISA in order to transfer to another provider, as you will lose the tax-free benefits of your investment. Instead, always use the transfer service ISA providers offer to carry out the transfer. This goes for both cash ISA transfers and Stocks and Shares ISA transfers.

If you accidentally withdraw money from an ISA before transferring you may be able to rectify the situation without impacting your allowance. You should consider the following steps:

• Contact Your ISA Provider: Reach out to your current ISA provider and explain the situation. They may have specific procedures in place for such cases.
• Reinvest the Withdrawn Amount: If you have already withdrawn the funds, you can reinvest them into a new Cash ISA, but this will count towards your annual allowance. Alternatively if the ISA from which you withdrew the funds is a flexible ISA then you may be able to pay the money back in to the ISA (as long as it's done in the same tax year as the withdrawal) and then make the transfer to a new provider without impacting your annual ISA allowance for the current tax year.

Can you transfer any type of ISA?

Yes, ISAs can be transferred to different types of ISAs, with the exception being Junior ISAs. Make sure that you check your paperwork as there may be exit fees. For example, fixed-term cash ISAs often charge a penalty if you withdraw or transfer your ISA before it matures. Transfer rules for Lifetime ISAs are a little more complex, check out our article ‘Can you transfer a Lifetime ISA (LISA)?‘ for more information.

Transferring your cash ISA to a Stocks and Shares ISA

If you are looking to transfer your cash ISA to a Stocks and Shares ISA, then you will need to decide where to invest your savings. Platforms like Hargreaves Lansdown will have ready-made portfolios or you can decide to choose the underlying ISA funds yourself. You could also consider transferring to one of a growing number of Robo-advisers, such as Wealthify, Nutmeg or Moneyfarm. Robo-advisers offer a range of off-the-shelf portfolios managed by their investment experts and computer algorithms which makes them attractive for investors (particularly novices) who want to invest while keeping costs low, yet who don't have the time or expertise to run their own portfolios.

Transferring your Stocks and Shares ISA to a cash ISA

You can transfer a Stocks and Shares or equity ISA to a cash ISA. While it is unusual to do so, you may want to if you no longer want the risk involved with investing in the stock market. It is worth remembering however, that many Stocks and Shares ISA providers pay interest on uninvested cash. Check out our article to find out the latest rates.
