Nationwide Building Society offers 'attractive' 6.5% interest savings account

Nationwide is offering an "attractive" 6.5% interest rate on a savings account. The lender's Flex Regular Saver account allows savers to put aside up to £200 per month for a year before the balance gets moved to an instant access savings account.

Caitlyn Eastell, Personal Finance Analyst at Moneyfactscompare.co.uk, told the Daily Express that January is the ideal time for savers to set new financial goals.

She added: "Regular savers can be a great first step towards maintaining a healthy savings habit. These accounts typically pay more generous returns than typical savings options, which allows for savers' hard-earned cash to grow even while inflation remains tricky."

Prices in Britain rose by 3.4% in the year to December 2025, up from 3.2% in November, according to the Office for National Statistics.

Given Britain's stubborn inflation rate, Nationwide's Flex Regular Saver is one of the better options out there at the moment, according to Moneyfacts' expert.

Ms Eastell said: "[It] sits among the best in its category, with an attractive headline rate well above the Moneyfacts Average Savings Rate at 3.32% and higher than most top easy-access accounts, which sit around 5%."

She said the account is variable, meaning the rate could rise or fall, so savers should keep a close eye on the top tables.

The expert added: "It's available to both existing and new current account holders, and those not already banking with Nationwide Building Society could earn an extra £175 when they switch to a qualifying current account using the Current Account Switch Service (CASS) and meet the basic criteria."

However, Ms Eastell said the regular saver has some limits. She explained that despite savers only being able to deposit £200 per month, this would still allow savers' cash to grow by around £40 more in a year compared to an "average" account earning 3.32%.

The market-leading regular saver pays 7.50% AER, but this is fixed for six months and savers won't be able to access their cash until it matures.

However, Ms Eastell said while Nationwide's account offers a slightly lower rate it offers more flexibility.

She explained: "The account offers three penalty free withdrawals a year which may give savers some peace of mind.

"However, it's crucial that savers remember that if they exceed this limit the rate drops significantly to just 1.05%."

While Nationwide's offer is among the best buys identified at the time of writing by Moneyfactscompare.co.uk, it sits below the top-placed Principality Building Society's 7.50% AER fixed rate six-month bond.

Principality is followed by Zopa's 7.10% AER and The Co-operative Bank's 7.00% AER 12-month bond. Both rates are variable.
