Savers have been given a much-needed boost in a world of dire rates, after app-only bank Atom launched a raft of best-buy fixed savings accounts – including a one-year account offering 2% interest.

This fixed saver account, the first product of its kind to offer a 2% rate since March 2016, beats the next-best offering from Secure Trust Bank (1.61%) by 0.39 percentage points.

We're not saying this is a world-beater as by historical standards it's still low, but it is at least a rare boost to current rates, smashing the competition out of the water.

What new deals has Atom launched?

As well as the new 2% one-year account, Atom's launched three longer-term products as well – all of which offer the best rate on the market for that length of fix. These are:

  • Two-year fix – 2.1% (next best, Charter Savings Bank at 1.75%)
  • Three-year fix – 2.2% (next best, Secure Trust Bank at 2%)
  • Five-year fix – 2.4% (next best, Secure Trust Bank at 2.2%)

See Fixed savings accounts for a full rundown of how the accounts compare.

With all four Atom accounts, interest is paid annually or monthly. There's a minimum deposit of £50, while the upper limit is £100,000.

I've never heard of Atom – who are they?

It's essentially a challenger bank – the company doesn't have any high-street branches and operates via an app that customers can download to their Android or Apple smartphone.

Atom is UK-regulated, which means your savings are protected under the Financial Services Compensation Scheme for up to £85,000 per person – read more in our Are My Savings Safe? guide.

Atom unveiled its fixed savings products last year and has since launched a range of mortgages. It's preparing to launch easy-access savings and current accounts in the next few months.

Clare Framrose, Atom's head of customer propositions, said: "Savers have had a tough deal with traditional banks, and we are determined to offer something better. Being purely digital, we are able to operate a lower cost model and pass these savings back through great interest rates."
