Here’s more information about the product.

Online Single Access (Issue 3)

Interest rate if 1 or fewer withdrawals are made per calendar year: 4.06% Gross PA/AER* variable.

Interest rate if 2 or more withdrawals are made per calendar year: 1.35% Gross PA/AER* variable.

Interest is calculated on a daily basis and added to your account annually on 31st December.

When will I get the higher interest rate?

The interest rate on your account will be the lower rate. However, if 1 or fewer withdrawals are made during the calendar year, the interest rate applied to your account on the 31st December will be the higher rate instead. From the 1st January your interest rate and withdrawals will reset.

* The gross rate (PA) is the rate before deducting tax at the rate applicable to savings income. The annual equivalent rate (AER) is a notional rate which illustrates what the gross interest rate would be if the interest was paid and added to the account annually.

The information contained in this table forms part of the terms and conditions of the account and should be read in conjunction with our General Savings Account Terms and Conditions for Retail Savings Accounts.

For our members

How can we help you today?

Exceptional telephone Staff. I would like to express how extremely helpful the staff members were on the telephone when dealing with Cash ISA questions, namely Jane, Laura and Catherine. They were all very knowledgeable with an excellent manner, and a credit to Harpenden Building Society which I highly recommend.
