Exploring Some of the Best ISA Providers as the New Tax Year Started

Using this period to look for new ISA providers is particularly important when it comes to individual savings accounts, as all ISAs act as a tax-free wrapper, which resets annually on the 5th April. 

Whether you’re a Cash ISA saver or a Stocks and Shares ISA investor, you’ll have a £20,000 allowance each tax year to subscribe to your accounts, whereby any profit you make can be claimed entirely free from capital gains tax (CGT) and income tax (however, Cash ISA allowances will be cut to £12,000 starting in April 2027). 

Reassessing your options can be a great way to get your allowance in check and begin using your new ISA with a full £20,000 to contribute throughout the year. 

But which ISA providers are the best for your needs? Let’s take a deeper look at the UK’s best platforms when it comes to individual savings accounts and why they could be a strong option when it comes to opening an account:

1. Wealthify

Owned and backed by Aviva, Wealthify is an ISA provider built around managed investing. A good fit for beginners and experienced investors alike who'd rather leave the day-to-day investment decisions to the experts.

Wealthify’s strength is that it features a simple and flexible approach to ISA saving and investing, whereby account holders can choose their level of risk when setting up a Stocks and Shares ISA, while also having the option of opting for an Easy Access Cash ISA for convenience in saving. 

Having won the Best Personal Finance Online Service accolade at the Personal Finance Awards 2025, Wealthify is a strong platform for ISA subscribers of all experience levels, and the platform’s helpful learning section is great for supporting customers on their journey. 

Wealthify operates a transparent fee structure, with no hidden strings or steep management costs. For Stocks and Shares ISAs, customers will pay a 0.6% management fee and 0.15% charge on investments for original plans. For its Cash ISA, there are no fees to open and maintain accounts. 

2. AJ Bell

Regularly recognised as a leading ISA provider for its high-level customer service and range of investment options, AJ Bell is a great choice for ISA subscribers looking for reliability and a wide range of choice for Stock and Shares ISAs. 

Listed as a ‘Recommended Provider’ with Which? for the past eight years, AJ Bell has worked best as a Stocks and Shares ISA provider, offering more than 4,000 funds as well as a range of high-quality research tools. 

Because of this extensive choice, the platform is particularly effective for investors who are looking for a more hands-on wealth management experience, and the freedom to pick and choose the stocks to add to their portfolio. 

AJ Bell’s fee structure is also relatively straightforward, with a 0.25% annual platform fee and a dealing charge from £1.50. The provider’s Cash ISA carries no fees for savers.

3. Trading 212

For ISA subscribers looking for competitive rates, Trading 212 takes some beating. Because of the platform’s status as a leading fintech broker, the provider’s ability to offer low-cost individual savings accounts is a particular advantage. 

Trading 212 operates as a zero commission provider with no annual platform management fees; however, users will pay 3.8% AER on their cash held within a Stocks and Shares ISA daily. On the other hand, the provider’s Cash ISA’s variable tracker rate of 3.6% is relatively strong and flexible withdrawals mean that subscribers can easily take their money out as and when it’s needed. 

One of the platform’s best features is its ‘pie’ structure for Stocks and Shares ISAs, whereby investors can buy into ready-made pies or have the freedom to pick and choose the stocks they want to add to their portfolio. 

4. Interactive Investor

Operating as a provider that’s particularly strong when it comes to managing larger portfolios, Interactive Investor is a great option for more experienced ISA subscribers. 

Unlike most providers that charge a percentage of your total savings, Interactive Investor operates using a flat monthly fee. If you have a portfolio worth more than £50,000, these monthly fees become far cheaper, offering an advantage over other providers. 

This unique structure means that investors can pay a monthly subscription starting from £4.99 to open an ISA. There’s also the choice of opening a managed Stocks and Shares ISA or opting for a more DIY-focused account. 

However, Interactive Investor offers no Cash ISA options, making this provider a strong choice for investors who would prefer Stocks and Shares ISA flexibility with a monthly subscription structure. 

5. Vanguard

Another ISA provider that exclusively offers coverage for Stocks and Shares ISAs is Vanguard, and the platform is a great option for competitively-priced investment options. 

Vanguard is a major global player when it comes to investing and has built a strong reputation for its low-cost index tracker funds. 

With a low cost 0.15% platform fee, which is capped at £375 each year, Vanguard’s Stocks and Shares ISA plan is a particularly strong option for investors who would prefer their accounts to be managed on their behalf. 

Vanguard features its own popular funds like LifeStrategy, making it an easy choice for passive investors who would prefer to ‘set and forget’ about their Stocks and Shares ISA over long periods of time. 

Choosing the Right ISA for You
