This is available up to 75% LTV for home buyers and remortgage and tracks the base rate plus 2.49%, while it comes with a £995 fee and a maximum loan size of £1m.
Abbey is also launching a three year fixed rate deal for home buyers and remortgage at 4.49% which is available up to 85% LTV and comes with a £495 fee and a maximum loan size of £550,000.
The deals will be withdrawn at midnight on June 30.
Miguel Sard, managing director at Abbey, says: “We are pleased to support the intermediary market with the launch of these market leading Key Account exclusives.
“Our flexible offset mortgage offers a fantastic rate to borrowers looking for the flexibility of an offset deal, while our three-year fix at 4.49% is designed to support borrowers with a higher LTV.“
Aaron Strutt, head of communications at Trinity Financial Group, says: “Brokers really appreciate these seven-day mortgages and the 1.99% tracker was great.
“It will be interesting to see how many more seven-day mortgages we get access to as I didn’t think the last limited offer would be extended. It’s normally HSBC who extend their special offer end dates.”
