An expert has explained her current top deals across the market
A cash ISA paying 4.57 per cent has been singled out as the “market leader” by a financial expert as she highlighted her “pick of the week” as ISA season draws to a climax. The HMRC tax year ends tomorrow, Sunday, April 6, 2026, and with it this year’s tax-free ISA savings allowance.
Each year savers can put up to £20,000 into ISAs, but anything unused is lost when the new tax year comes around on Monday and the allowance resets. This year is arguably even more important, as from April 2027 people under the age of 65 putting money into cash ISAs will be limited to £12,000 – although the overall ISA limit will remain at £8,000, with the difference having to be put into a stocks and shares ISA.
With all that in mind, anyone with last-minute cash to drop into an ISA before 11.59pm on Sunday to make the most of this year’s limit could score a win if they take up an account recommended by Caitlyn Eastell, personal finance analyst at Moneyfactscompare.co.uk. She recommended the Plum Cash ISA as her top pick right now, although she did also offer a note of caution.
Caitlyn said: “This week Plum has increased the rate on its Plum Cash ISA for new money only, maintaining its position as the market-leader when compared to its peers. The account pays 4.57 per cent AER and savers can invest as little as £1.
“However, as is the case with many flexible ISAs, savers should note the generous 2.03 per cent AER bonus rate, which expires after 12 months, so it’s crucial they review the deal once this expires. This account may be best suited for savers who may need to dip into their deposits frequently, as they have unlimited withdrawals without penalty.
“Investors who wish to transfer into this account should note that they will receive a lower headline rate of 4.07 per cent AER. Overall, this deal takes a position as a Moneyfacts ‘Best Buy’ and earns an Excellent Moneyfacts product rating.”
Caitlyn also highlighted a few other financial products around the market. Firstly, the MBNA Fixed Saver One Year.
She said: “MBNA has increased the rate on its Fixed Saver One Year. The boost improves its appeal when compared to other fixed-rate bonds with similar terms and now pays an attractive 4.52 per cent.
“This account may entice those looking to receive guaranteed returns over the next year. Savers will need to deposit at least £1,000 but, adding to its appeal, further additions are permitted for 14 days from account opening via a nominated account.
“As is common with fixed bonds, savers must be comfortable locking away their cash as no earlier access is permitted, so careful planning is a must. Overall, this deal earns an Excellent Moneyfacts product rating.”
Caitlyn also looked at the mortgage market, highlighting one residential mortgage and one buy-to-let deal.
Speaking about the Hinckley & Rugby Building Society two-year discounted variable rate mortgage at 75 per cent loan-to-value, she said: “Hinckley & Rugby Building Society has added a few two-year discounted variable rate products for remortgage customers to its range. The deal is now priced at 4.34 per cent, with a 2.55 per cent discount, for borrowers with a 25 per cent share.
“This may be a tempting option for borrowers as the initial pay rate is lower compared to equivalent fixed rate deals, however, as it’s variable this can quickly change and so should be carefully considered. Adding to its appeal, remortgage customers can benefit from a £250 cashback incentive which can help offset some of the already reasonable £800 product fee.
“Another thing borrowers will need to consider is this deal has a maximum borrowing limit of up to £500,000. On assessment, the deal earns an Outstanding Moneyfacts product rating.”
In terms of buy-to-let, Caitlyn highlighted the NatWest two-year fixed rate mortgage, at 60 per cent loan-to-value.
She said: “The latest change from NatWest sees it increase rates for landlords by 0.28 per cent. One deal to see the rise is the two-year fixed rate at 60 per cent loan-to-value for house purchase customers.
“The deal now charges 5.21 per cent until June 30, 2028, however, this may still be an enticing option for landlords looking to minimise costs as there are no payable fees and it includes a free valuation incentive. However, this deal is only available online which some may want to consider. When assessed as a whole, this product remains at the top of its sector despite the rise and earns an Outstanding Moneyfacts product rating.”
