Why aren't instant-access savings rates rising?

While fixed savings deals are hitting two-year highs, instant-access rates appear stuck in the slow lane. 

Moneyfacts data shows the average instant-access rate has been frozen at 2.53% AER since July 2026, with top deals struggling to break 5%. Meanwhile, fixed-rate bonds have surged to as high as 5.37%.

We investigate why instant-access rates aren’t budging and show you how to boost returns without locking money away for too long.

What's happening to instant-access rates?

Over the past few weeks, multiple providers have rolled out better fixed-term savings deals, with average interest on one year and longer-term bonds rising steadily since March 2026. You can now find an account paying as high as 5.37% AER.

Instant-access rates, on the other hand, appear more stubborn. Moneyfacts data shows the average rate has been stuck at 2.53% since July 2026 and the best deal has struggled to rise above 5%.

This graph shows how average interest rates on savings accounts have fared since August 2020:

What's behind the lack of momentum? 

Savings rates tend to track the Bank of England’s (BoE) base rate. After 14 consecutive hikes between December 2021 and August 2023, savings rates soared. When the BoE started cutting, savings interest fell too.

The base rate has been at 3.75% since December 2025, which helps explain why instant-access savings rates have stayed steady. But it’s not the whole story. 

Competition between providers and demand for particular accounts can also push rates up or down. 

Uncertainty is another reason instant-access rates lag behind fixed deals. Banks and building societies use savers’ cash to lend or invest for a profit, but money in instant-access accounts can be withdrawn at any time. That makes it harder for these institutions to manage their cash flow.

By contrast, fixed-term bonds give providers certainty over how long they can use the money, and they’re often willing to pay more for it.

Are better instant-access deals coming soon?

Instant-access rates may be stuck for now, but that could change on 5 November, when the BoE makes its next rate decision. With inflation jumping to 3.5% in September, a base rate hike could be back on the cards, potentially paving the way for higher savings rates.

But Rachel Springall, finance expert at Moneyfacts, warns people not to wait for that to happen: 'Savers should remember that returns across the savings market are not always tethered to rises or falls in the base rate. 

'Rather than trying to predict what comes next, consumers should regularly review their account and be prepared to switch if necessary. Loyalty does not pay when it comes to savings, and some of the best returns can often be found by looking beyond their main bank account provider.'

What are the best deals right now?

As the table shows, many of the top rates come from lesser-known brands – such as Cahoot, Tembo and Ford Money.

The absence of big high street names is partly because these challenger banks and platforms don't usually have physical branches. This means they have fewer overheads to worry about, so can offer higher rates while maintaining profit margins.

If you're nervous about saving with a bank or platform you've never heard of, find out whether it's covered by the Financial Services Compensation Scheme (FSCS). This protects up to £120,000 of a saver's pot if a bank goes bust.

3 ways to get a better deal without locking in

There are better variable-rate deals than some of those listed in our table, but be prepared to jump through a few hoops to get them.

Here are three of the most common caveats and restrictions you'll have to agree to if you want to boost returns without locking in:

1. Withdrawal limits

Some top-rate products limit the number of withdrawals that savers can make. In exchange, providers usually reward you with a higher rate of interest. 

Zopa currently offers 4.56% AER on its instant-access product (including a 1.05% bonus for 12 months), but only allows you take money out three times a year. If you go beyond the withdrawal limit, the rate drops to just 2%.

2. Existing customers only

Some of the top savings accounts on the market are often reserved for existing customers of the bank or building society. That usually means you need a current account, but you may also qualify if you have another financial product, such as a mortgage or investment account.

For example, Leeds Building Society currently offers the best instant-access account, with a rate of 5.5% AER. However, it's only available to people who have a Leeds Building Society shared-ownership mortgage.

Chase is also offering a 4.5% instant-access deal (with 12-month 2.23% bonus), but it's only available to its current account customers.

3. Notice periods

Notice savings accounts work in a different way to instant-access deals. Instead of being able to withdraw your money when it suits you, you'll have to tell your provider in advance that you want to take cash out. 

For some accounts, you'll need to inform the bank up to six months in advance. For example, Birmingham Bank's product offers 4.4% AER, but it requires 95 days' notice. GB Bank's 4.38% account requires 150 days' notice.

These accounts are unlikely to suit you if you may need to get at your savings unexpectedly. If you do make an emergency withdrawal from a notice savings account, you're likely to lose some interest.
