The new individual savings account (ISA) also allows access to up to 25% of the initial amount invested at any time, without notice or penalty, added Leeds.

Kim Rebecchi, director of sales and marketing at Leeds Building Society, said: This is a simple, straightforward tax-free product paying 0.75% above bank base rate and complements our existing ISA range which includes a five-year Escalator ISA, an Inflation Buster and instant branch and online ISAs. This tracker also allows an unlimited number of withdrawals of up to 25% of the initial amount invested, without notice or penalty, providing additional flexibility and peace of mind.
