Welcome to Whistletree

About us

Let us introduce ourselves

Hello and welcome to Whistletree. On 2 May 2017 we became the new managers of your Airdrie Savings Bank account, which includes your mortgage or loan, or even both. You should have received a letter from Airdrie Savings Bank to tell you about this and will also receive a letter from Whistletree letting you know about a few things that have changed in relation to your account. Depending on how you make your monthly payments you may also need to take some actions.

Please see our FAQs page for the answers to some questions you may have in relation to your account.

Whistletree is a trading name of TSB Bank plc. We'll be providing a safe home for your account.

We're really pleased to have you on board.

We are committed to providing products and services of the very highest standards. If you feel that we haven't lived up to your expectations in any way, we'd like to know so we can put things right for you.

We take all complaints seriously. Many issues can be dealt with straight away, but some do take a little time to investigate thoroughly. If this happens, we will get a specialist from our Customer Services team to resolve the issue. The Financial Conduct Authority (FCA) gives us eight weeks to resolve complaints - though we will aim to get your complaint resolved well before this deadline.
