Best savings account of the week: Banks offering 'new market-leading rates' of 7.5% in boost for savers

Experts are saying "review and switch" bank accounts before providers begin to slash interest rates later this year.

Moneyfactscompare have published a list of the best savings accounts for the week beginning June 30, 2025, with Nationwide Building Society, NatWest and Royal Bank of Scotland being featured in the ranking.

Rachel Springall, Finance Expert at Moneyfactscompare.co.uk said: "Savers looking to secure a guaranteed return on their cash will be delighted to see some much-welcomed competition across fixed rate bonds and ISAs in the top rate tables over the past week. Several challenger banks made rate hikes which has led to a new market-leading rates, across varying terms.

"Picking the right savings account does come down to someone’s individual circumstances, and aside from chasing the top rates, it’s important to ensure they stay within their Personal Savings Allowance (PSA) and take advantage of their ISA allowance to protect their hard-earned cash from tax.

"Loyalty does not pay, so it is essential for savers to proactively review and switch their savings pots. Some of the best rates on the market come from challenger banks and mutuals, which should not be overlooked.

"Taking time out to check any old pots against the latest competition is wise, as is signing up to rate alerts or newsletters to keep in the know."

Springall continued: "GB Bank also jumped into the fray with its two, three and five-year fixed rate bonds, but didn’t quite grab the top spot from their competition.

"The fixed rate cash ISA market was much more heated, with numerous brands improving rates and securing market-leading positions.

“One area of the savings market that might get overlooked is notice accounts, where in fact, there has been some exciting rate competition over the past week.

"Several challenger banks have increased rates, propelling them towards the top of the sector, including RCI Bank UK, Oxbury Bank and GB Bank.

"These accounts are great for savers who don’t want commit to a fixed rate bond and have a good idea on when they might need access to their cash. However, these do pay variable rates, so its wise to keep that in mind should rates come down in the months ahead.

“Those who want to instil a regular savings habit may want to grab a regular savings account, and thankfully, the top rate deal has held firm over the past week. Principality Building Society continues to pay a rate of 7.50 per cent AER fixed for six months on its regular savings account, ideal for those want to carefully plan towards a specific goal."
