No, there’s no requirement to invest cash held in your ISA. Once you’ve added funds to your ISA portfolio, they can remain as cash for as long as you like.
At InvestEngine, any cash in your ISA still counts towards your annual ISA allowance, even if you haven’t yet used it to buy ETFs.
Things to keep in mind
- ISA cash is not automatically invested, you need to choose when (and if) to invest
- Cash held in your InvestEngine ISA does not earn interest
- You can hold it temporarily if you’re planning to invest later, for example, using a Savings Plan or waiting for the right opportunity
Why might you keep cash uninvested?
Some clients hold ISA cash if they:
- Prefer to invest gradually over time (pound-cost averaging). Read more about this on our blog.
- Want flexibility while they explore ETF options
How to invest your ISA cash
If you’re using:
- A DIY portfolio: Click into your ISA portfolio and select iInvest, then choose how much cash to invest
- A Managed or LifePlan portfolio: Cash added before 2pm is typically invested the same day (or next business day if after 2pm)
-
