An ISA is just a tax wrapper — it doesn't have a religion. Whether it's halal depends entirely on what's inside it. Here's how to tell the difference, and which UK options are worth considering.
An ISA (Individual Savings Account) is a UK government scheme that lets you save or invest up to £20,000 per tax year without paying tax on any gains or interest. The ISA is a wrapper — it doesn't determine what you invest in, just how it's taxed.
There are several types: cash ISAs, stocks and shares ISAs, Lifetime ISAs, and Innovative Finance ISAs. Each works differently and carries different implications for whether it can be used in a halal way.
| ISA Type | Halal potential | Why |
|---|---|---|
| Stocks & Shares ISA | ✓ Can be halal | Depends on what funds are held inside |
| Cash ISA | ✗ Generally not halal | Pays interest (riba) |
| Lifetime ISA | ✓ Can be halal | If invested in Sharia-screened funds |
| Innovative Finance ISA | ✗ Generally not halal | Usually peer-to-peer lending with interest |
It can be — but only if the investments held inside it are Sharia-compliant. The ISA wrapper itself is neutral. What matters is whether your money is invested in permissible companies and funds.
Halal: A stocks and shares ISA holding Sharia-screened ETFs or funds — where stocks are filtered to remove alcohol, gambling, weapons, tobacco, and interest-based finance companies.
Requires care: A stocks and shares ISA holding a standard index fund like the S&P 500 or FTSE All World, which will include banks, insurance companies, and other prohibited sectors.
No — a standard cash ISA pays interest on your savings, which is riba and prohibited in Islam. Even though the interest is tax-free, it is still interest. Most Islamic scholars would consider a conventional cash ISA impermissible.
If you want a halal alternative to a cash ISA, look at halal savings accounts from Al Rayan Bank or Gatehouse Bank, which pay profit share rather than interest.
The fund or platform should apply a Sharia screening process to remove companies involved in alcohol, tobacco, gambling, weapons, pornography, and conventional banking and insurance.
A credible halal investment platform will have a Sharia supervisory board — a panel of Islamic scholars who independently oversee and certify the screening methodology.
Conventional bonds pay interest and are not permissible. A halal ISA should not hold conventional bonds. Sukuk (Islamic bonds) are the halal equivalent and are acceptable.
Some platforms offer a purification process — calculating and removing any small percentage of income that came from incidental non-halal activities, which is then donated to charity.
Wahed Invest — the most prominent halal investment platform in the UK, offering a stocks and shares ISA with fully Sharia-screened portfolios, overseen by a Sharia supervisory board. Available via their app.
Cur8 Capital — offers Sharia-compliant investment options in the UK, though their ISA wrapper availability should be confirmed directly with them.
It's worth noting the UK halal ISA market is still relatively small compared to conventional options. This is an area that's growing, so checking the latest options is worthwhile.
