Is Principality Building Society legit?
LegitOwned by its members, Principality Building Society is a real Welsh lender, but savers need to watch the date a fixed bond or ISA ends. The rates in its maturity pack are not guaranteed, and if you do nothing the money moves to the account named in that notice, which may pay less.
What we checked
- Head office in Cardiff city centre
- Mortgages in England and Wales only
- Website in English and Welsh
- Ratings on other review websites: 3/5
Watch out for
- Exclusive member rates at maturity that you must apply for within 14 days of the end date.
- An online-only account, where money can only be sent out to the linked account it has verified as yours.
- A savings account left untouched for 15 years, which counts as dormant and stays locked until you prove your identity.
Maturity rate lower than your pack suggested?
We help you write it, it gets its own public page, and you can have it sent to Principality Building Society as a formal letter.

What is the Principality Building Society complaints procedure?
Principality Building Society either settles a complaint quickly and confirms it in a Summary Resolution Letter, or sends a formal acknowledgement and investigates. While it investigates, Principality sends progress updates, and it ends with a final response, in writing or by email, explaining the outcome and the reasons for it; staff may phone you first to talk it through. You can complain in a branch, by phone, by email, by freepost letter or through its social media accounts. Give your account or mortgage number, the dates and the outcome you want.

Does Principality Building Society lend on homes in England?
Yes. Principality Building Society lends on properties in England and Wales, but not elsewhere in the UK, and its products are only for UK residents. Its branches and agencies are in Wales and the border areas, so members further away use its online and phone services. For a mortgage application or product switch, keep the application reference, the date you sent each document and every letter or email from Principality.
Can I take a Principality Building Society complaint to the Financial Ombudsman Service?
Yes: the Financial Ombudsman Service settles disputes between consumers and financial businesses in the UK, and that covers complaints by Principality members about its savings, mortgage and other financial products and services. The Financial Ombudsman Service generally expects Principality to have had the chance to put things right first, so keep a record of every call, branch visit, email and reference number.
