The estimated interest is for illustrative purposes only and is intended to help you compare accounts. It doesn’t take account of individual circumstances. All interest rate information should be read in conjunction with the full product information and the general terms and conditions for savings accounts. The figures below are based on your initial deposit entered and monthly deposits entered over a 12‑month period, using current interest rates. This projection assumes that the initial deposit is made when the account is opened, that each monthly deposit is made on the first day of each calendar month, that no further money is paid in or withdrawn, and that the funds are held for the full interest period with no change to the interest rate. For products with tiered interest rates, the calculation shown is based solely on the highest interest rate available within the product. Please refer to the individual product terms and conditions for full details, including how tiered interest rates and withdrawals apply.

Our Story

Read Mutual magazine

It was much easier than I anticipated to open the Trust account and then register to manage this online. The application and accompanying documents were submitted via email and registration was managed online. There are a limited a number of banks and societies offering these products and services and Harpenden Building Society made it a stress-free process.

Couple planning finances and budget in home office

This is a short note to express our gratitude for the warm and helpful assistance we received when trying to set up our Savings ISAs at the Harpenden store. We were particularly grateful for the way the staff patiently took us through the paperwork with such good humour.
