Savings platforms widen access to tax-free cash ISAs as savers hunt top rates

Savings platforms including Hargreaves Lansdown, Flagstone and Raisin are expanding their product ranges to include cash ISAs, giving savers a way to access competitive, tax-free rates with a single sign-up.

The move comes as the number of savings deals on the market reached a record 2,289, according to rates monitor Moneyfacts, though only about a quarter of those offers outpace the Bank of England base rate of 4 percent. Platforms allow customers to open one account with the platform, transfer funds in, and then allocate money across multiple provider products without completing separate application forms for each account.

Until recently, many platforms focused on fixed-rate bonds and easy-access accounts. The addition of cash ISAs brings tax-free options to customers who want to shield savings interest from income tax while avoiding repeated paperwork. Flagstone said it will add ISAs from ten providers ahead of the end of the tax year in April. Hargreaves Lansdown (HL) is offering 13 easy-access ISAs and several one- and two-year fixed-rate cash ISA options.

Some headline rates appearing on platforms are competitive with the best standalone deals. Hargreaves Lansdown lists an easy-access cash ISA from Paragon at 4.3 percent and a one-year fixed-rate cash ISA from Chetwood Bank at about 4.32 percent. Platform operator coverage varies: Flagstone lists roughly 68 banks and building societies, HL more than 20, and Raisin about 40. That breadth helps savers compare multiple providers through a single interface.

There are caveats. Customers cannot always transfer an existing cash ISA directly into a platform cash ISA. For example, HL requires some existing cash ISAs to be transferred into its stocks and shares ISA held in cash before being moved into its cash ISA product. Savers should check transfer rules and any limits or cooling-off periods before moving accounts to avoid inadvertently losing tax benefits or access to funds.

Industry observers say platforms can reduce the paperwork involved in switching or opening multiple accounts, making them particularly useful for customers who prefer convenience over hunting the absolute top rate. Moneyfacts noted that while a devoted rate-hunter might still find marginally higher offers by switching between numerous providers, platforms can deliver near-best rates without repeated application forms.

Analysts also point out that product availability, promotional rates and provider lists on platforms change over time, so customers should compare current rates across platforms and standalone offers. The platforms' expansion into cash ISAs follows consumer demand for simpler ways to manage savings amid a crowded market of branded deals and short-term offers.

For savers weighing options, the platforms present a trade-off between convenience and the potential marginal gains from manually switching accounts. Financial providers and comparison services advise reading product terms, transfer conditions and any fees before moving funds, and verifying that a platform's provider list includes the kinds of accounts a customer prefers.

As the market evolves, platforms' addition of cash ISAs is likely to remain attractive to customers who want tax-free savings with less administrative burden, while more persistent switchers may continue to shop around for the very top headline rates.
