Best savings accounts 2025
Discover the top instant-access, fixed and regular savings rates on the market, plus the best banks and building societies to save with
Saving rates soared over the last couple of years, but they've now started to fall in the wake of the Bank of England cutting its base rate.
With lower returns likely to be a theme of the coming months, you'll need to shop around to ensure you're getting the best deal.
In this guide, we reveal the top rates across instant-access accounts, regular savings accounts and fixed-rate bonds. We also detail the best savings providers based on customer experiences and expert Which? analysis, so you can find the right home for your cash.
The best savings rates in May 2025
Our experts regularly scour the market for the best rates so you don't have to.
See our tables for the latest rates on everything from instant-access accounts to five-year fixes. The top rates are based on an initial deposit of £1,000 (instant-access accounts) or £5,000 (fixed-rate bonds).
Some providers offer a choice of how often interest is paid. Where this applies, we have listed all the options available in the 'Interest paid' column of each table.
The information in this article is for information purposes only and does not constitute advice. Please refer to the particular terms and conditions of the savings account provider before committing to any financial products. Please note that minimum and maximum deposit amounts vary, even across products with the same rate, so make sure you consider the full details before you opt for a new account.

The best regular savings accounts
Regular savings accounts can offer higher interest rates than other savings accounts, but some require you to have a current account with the same provider.
Unlike fixed-rate bonds or instant-access accounts, which allow you to deposit a lump sum, you'll be much more restricted on the amount you can pay into a regular savings account. Maximum monthly deposits are typically between £250 and £500.
What's more, the rates sometimes only apply for a limited time, often 12 months.
Minimum and maximum deposit amounts vary, even across products with the same rate, so check the full details before you choose an account.

The best savings providers
Customer service is an important factor for many people when choosing a savings account. But how do you find a bank or building society that combines great rates with top-notch service?
We asked thousands of savers to rate their bank or building society, enabling us to create unique customer scores for all the major providers.
We've also analysed thousands of savings products and given each provider an overall interest rate score, highlighting which companies offer consistently competitive rates. The full results from our most recent analysis are as follows:
RECOMMENDED PROVIDER Moneybox (76) | 83% | 83% | - |
Chase (161) | 81% | n/a | |
RECOMMENDED PROVIDER Marcus by Goldman Sachs (102) | 79% | 86% | - |
Coventry Building Society (102) | 78% | 78% | |
Monzo Bank (210) | 77% | n/a | |
Nationwide Building Society (506) | 77% | 76% | |
RECOMMENDED PROVIDER Yorkshire Building Society (99) | 77% | 88% |
The results are based on an online survey of 4,524 members of the public conducted in August-September 2024. The customer score is based on satisfaction with the brand and likelihood to recommend. Sample sizes in brackets. ‘-’ means not enough responses to include a star rating. The interest rate score is based on analysis of Moneyfacts data collected weekly, between 24 June 2024 and 9 September 2024. An interest rate score of 100 represents the market-leading rate. We only generated an interest rate score for providers that offer accounts without opening restrictions.
Which? Recommended Providers for savings
Each year, we name the best savings providers as Which? Recommended Providers (WRPs). To win this award, the bank or building society must:
- achieve a customer score of 75% or above
- achieve an interest rate score of 80% or above
- be fully covered by the UK Financial Services Compensation Scheme (FSCS)
- not have significant barriers to opening an account, for example high minimum deposit rules or opening restrictions.
- offer products that are available nationally and are not tied to the purchase of another product with the same provider.
This year, our WRPs (in customer score order) are:
Moneybox
Moneybox is a new addition to our customer satisfaction table. In its first year offering savings accounts, it achieved the top customer score in our survey. Customers were impressed with its mobile banking app, giving it five stars.
Moneybox offers an instant access savings account that pays 3.15% AER. It also offers a very competitive instant access cash Isa, with a variable rate of 4.85% (rate drops to 4% after twelve months).
Marcus by Goldman Sachs
Marcus by Goldman Sachs received a customer score of 79%. Savers gave it top marks for its application process and communication, as well as its mobile app and online banking service.
Marcus currently offers an instant-access savings account and cash Isa that both pay a competitive variable rate of 4.01% AER (3.94% gross), including a 0.49% (gross) bonus rate. This means the rate will fall to 3.5% AER (3.44% gross) after the first 12 months.
Yorkshire Building Society
Yorkshire Building Society earned a customer score of 77%. Savers gave it high ratings for its customer service, application process, regular communications, and online banking service.
It is the only WRP for savings with a branch network. Yorkshire also has the widest range of savings products out of WRPs.
Yorkshire Building Society restriction-free instant-access account offers 4.1% AER.
Zopa
Zopa achieved a customer score of 77%, with customers giving it top ratings for its application process and mobile banking app.
Zopa instant-access account offers 3.5% AER.

Which savings accounts beat inflation?
Inflation rose to 3.5% in April 2025, according to the Office for National Statistics (ONS), up from 2.6% in March 2025.
Which? analysis of Moneyfacts data conducted on 27 May found 1284 savings accounts offering rates higher than 3.5% (AER on £1,000). That's 58% of the market and includes accounts with opening restrictions.
For accounts anyone can apply for (including junior Isas and children's savings accounts), 60% (1,094) offered rates above April's inflation figure.
Could you earn more interest from a current account or investment?
Despite a series of rate cuts on popular interest-paying current accounts, many still offer meaningful returns, albeit only on small balances. You'll also need to make sure you pay in the required minimum monthly amount to qualify for interest.
For example, Nationwide's FlexDirect current account is the highest-paying. It currently pays 5% AER on balances up to £1,500, but only for the first 12 months, generating a maximum return of £75. The rate will drop to 1% AER after that. You're also required to pay in at least £1,000 a month.
You might also consider investing, which can - though doesn't always - earn you more than a savings or current account. Our guide to the best stocks and shares Isas explains more.

How to transfer your savings to your new account
Once you've selected and opened an account it's time to transfer your money.
If you're moving existing savings from elsewhere, you'll need to check what your options are with your current provider.
Some providers allow you to make a BACS transfer straight to your new account. Others will require you to transfer the money to a current account first.
It may also be possible for your new provider to initiate a Direct Debit from your old account.
Once you've switched savings accounts, don't rest on your laurels. If the new savings account has an introductory bonus, make a note of when it ends, as you may want to switch again to make sure you're still getting a good deal.
If it's a variable rate account, keep an eye on your rate to make sure it stays competitive.
