Update: Following the recent announcements by the Welsh First Minister and UK Prime Minister, our branches will be providing a counter service, available for deposits and withdrawals only.

We ask all customers visiting our branches or agencies to wear protective masks on entering. Following a review of the government guidance, all Principality colleagues will wear a face covering when in the banking hall, any public area or behind a counter not protected by a Perspex screen. Social distancing will be in effect as normal. 

You can find out more about guidance on face coverings on the government website

Treharris Agency:

We are sorry to tell you that our Treharris partner agency, Weathersby Estate Agents, has decided to close their operation as of 4 February 2021. These circumstances are unfortunately beyond our control, but we’re grateful to the staff for their support over the past eight years. 

This means from 5 February 2021, Members who use our Treharris agency will need to visit another Principality branch to make any face-to-face transactions. 

Your nearest Principality branch 

You’ll be assured of the same friendly hello and helpful service from your nearest local branch which is in Blackwood, you can find us at 129 High Street, Blackwood, NP12 1AB, telephone number: 01495 224687.

In our branches:

To help ensure the safety of both our Members and colleagues, during lockdown we will be unable to offer branch appointments. We will aim to re-book all appointments booked during this period when safe to do so, depending on the guidance available at the time.

We offer many of our services by phone and online. To avoid leaving your home, you can contact your local branch directly or call our Contact Centre on 0330 333 4000.
