Cynergy Bank changed its Online ISA to Issue 5 and upped the rate by 0.10% to 1% on 21 September, Moneyfacts data revealed.

But savers will now have a choice of two easy access ISAs paying 1% AER as Skipton Building Society launches its eISA tomorrow.

The Cash eISA Saver Issue 6 pays interest monthly or annually and has a minimum £1 deposit amount. There are no restrictions and no notice is required on withdrawals. It also allows transfers in.

Skipton is also relaunching its fixed rate range, including a 15-month fixed rate bond paying 1%, and these products are available in branch, by telephone, post and online.

The launch and re-launch come after Skipton last week unveiled its Online Bonus Saver (issue 7), paying 1.20% AER/gross. However, due to unprecedented demand, it was pulled just days after going live.

Skipton said the message for its eISA is to “get yours while it lasts”.

Maitham Mohsin, Skipton Building Society’s head of savings, said “We were delighted that thousands of people were able to take advantage of our Online Bonus Saver.  We are now delighted to offer our new market-leading eISA Saver, which goes straight to the top of the Best Buy easy access ISA tables.

“We hope this will not only be of interest to customers who haven’t yet utilised their current year ISA allowance, but also to those who have built up ISA balances over time elsewhere which they can transfer to Skipton Building Society and take advantage of the market leading rate.

“We will support our customers who continue to put money aside to save for their future. We know everyone is finding the current situation difficult but we’re proud to continue our commitment to offer customers great value savings products.”
