Principality Building Society: Savings, Mortgages & Online Services

Principality Building Society customers usually need one of a few practical things: compare a savings account, manage a Cash ISA, log in to an online profile, change a linked account, switch or move a mortgage, find a branch, report a scam or speak to the right support team.

This guide puts those routes in one place. It is written for UK customers, with particular attention to Principality’s Welsh branch network, savings services, online-profile system and mortgage support.

What Principality Building Society Does

Principality is a mutual building society founded in Wales. It focuses mainly on savings and mortgages rather than trying to operate as a full-service current-account bank.

Its services include easy-access savings, regular savers, fixed-term accounts, Cash ISAs, residential mortgages, existing-mortgage management and customer support through online, telephone and face-to-face channels.

500,000+ Members according to Principality’s current corporate information.
6th Principality’s stated position among UK building societies by size.
165 years Principality highlights more than a century and a half of building-society history.
Welsh roots Head office in Cardiff with a substantial physical presence across Wales and the borders.
Do not choose a product only because Principality is a mutual. Member ownership is an important organisational difference, but savings rates, access conditions, mortgage fees and service needs still need to be compared product by product.

Principality Savings Accounts: Choose by Access, Not Just AER

Principality offers several savings structures. Before looking at the live rate, decide whether the money is an emergency fund, regular monthly saving, a fixed lump sum or tax-efficient ISA saving.

Savings type
May suit
Check before opening
Easy access
Money you may need during the year.
Withdrawal limits, bonus periods, variable rate and whether the account is online-only or branch-based.
Regular saver
Customers building savings gradually.
Maximum deposits, account term, withdrawal restrictions and what happens at maturity.
Fixed term
Money you can leave untouched for the agreed period.
Deposit window, maturity date and whether withdrawals are allowed.
Cash ISA
Tax-efficient saving within current ISA rules.
Annual allowance, withdrawal flexibility, transfer rules and whether the product accepts transfers in.
Branch savings
People who prefer face-to-face account service.
Whether the exact product is branch-exclusive and which branches or agencies provide the service.
Rate warning: Principality’s savings rates and bonus rates can change. Use the live comparison page for the AER applying when you open an account rather than treating a rate quoted in an older article as permanent.

Official savingsPrincipality Savings Accounts

After opening this link:

  1. Choose the savings category that matches how often you need access.
  2. Compare the current AER and whether it is fixed or variable.
  3. Check the minimum opening deposit and maximum permitted balance.
  4. Read withdrawal limits and bonus conditions carefully.
  5. Check whether the account is online-only, branch-only or available through more than one channel.
  6. Download the account terms and FSCS information before placing a large balance.

What Is a Principality Linked Account?

Principality uses a linked account for some online-only savings products. This is an account with another bank or building society that Principality has verified belongs to you.

The linked account helps reduce fraud risk when money is transferred out of an eligible Principality savings account electronically.

Use your linked account for

  • Supported electronic withdrawals from eligible online savings accounts.
  • Moving savings to an account Principality has verified as yours.
  • Reducing the chance of money being sent to an unverified third-party account.

Need to change it?

  • Log in to your online profile.
  • Send Principality a secure message where supported.
  • Or call 0330 333 4000.
  • Do not send full account-security information through ordinary email.
Online-only account: do not assume a branch can complete every transaction for an account specifically designed to be operated online. Check the product terms or call Principality before travelling.

Principality Cash ISA Transfers: Keep the Tax-Free Wrapper Intact

If you want to move an existing ISA, use the receiving provider’s formal transfer process. Withdrawing the balance to an ordinary current or savings account can remove the ISA status of that money.

Transfer another Cash ISA to Principality Choose a Principality Cash ISA that accepts transfers and follow the official transfer instructions during or after application.
Transfer a Stocks & Shares ISA Principality provides a dedicated transfer process for moving eligible Stocks & Shares ISA money into a Principality Cash ISA.
Move between Principality ISAs Principality currently requires an internal transfer between its own Cash ISAs to move the entire balance.
Transfer away Ask the new ISA provider to arrange the transfer rather than withdrawing the savings yourself.
£20,000 Current overall ISA allowance for the 2026/27 tax year.
15 business days Principality’s stated typical timescale for a Cash ISA transfer.
30 calendar days Principality’s stated typical timescale for a Stocks & Shares ISA transfer.

Official ISA transferPrincipality ISA Transfer Guidance

After opening this link:

  1. Choose whether you are transferring into Principality, between Principality ISAs or away to another provider.
  2. Check whether your chosen Principality ISA accepts transfers.
  3. Use the online transfer form or the correct paper transfer form.
  4. For current-tax-year money, read the full-transfer requirements carefully.
  5. Check whether the existing ISA has a notice period or loss-of-interest condition.
  6. Keep the transfer confirmation and wait for the providers to move the ISA money directly.
Common ISA mistake: do not withdraw ISA money to your current account simply to move it to another provider. A formal ISA transfer is normally the safer route for preserving its tax treatment.

Principality Mortgages: Pick the Correct Journey First

Principality’s mortgage route depends on whether you are buying your first home, moving, remortgaging, already have a Principality mortgage or need help with payments.

First-time buyer Review deposit, affordability, buying costs and suitable mortgage types before committing to a property budget.
Moving home Check whether your existing mortgage product can be ported and whether additional borrowing is required.
Remortgage Compare the total cost after fees, valuation, legal work and any Early Repayment Charge from your existing lender.
Existing customer Check product-switch, overpayment, term-change, redemption and porting options before starting a full new mortgage application.
0330 333 4002 Principality’s published telephone number for new mortgage enquiries.
0330 333 4000 General and existing-customer mortgage support route for many account queries.
Mortgage warning: compare the rate, product fee, Early Repayment Charge, term and total repayment cost. Your home may be repossessed if you do not keep up repayments on your mortgage.

Official mortgagesPrincipality Mortgages

After opening this link:

  1. Choose first home, moving home, remortgage or existing-customer support.
  2. Review the mortgage range and eligibility applying to your journey.
  3. Compare fees as well as the displayed rate.
  4. Check whether advice or another application route is more appropriate for your situation.
  5. Keep the mortgage illustration and offer documents if you proceed.

Switching or Porting an Existing Principality Mortgage

A product switch keeps your borrowing with Principality but moves to another available mortgage product. Porting is different: it involves applying to transfer an existing mortgage deal to a new property.

Why use it
Important check
Product switch
Stay with Principality and choose another eligible mortgage product.
Deal-end date, new rate, product fee, effective date and any restrictions.
Port mortgage
Move home while applying to retain the existing mortgage deal on the new property.
A new application and lending assessment are still required.
Borrow more
Increase borrowing when eligible.
Affordability, loan-to-value and the rate applying to additional borrowing.
Remortgage elsewhere
Access another lender’s product range.
ERC, legal work, valuation, affordability and completion timing.
Principality porting rule: its current guidance says an eligible existing rate can be portable to another property in England or Wales, subject to a new application, current lending criteria and the terms of the existing mortgage.

Common Principality Mistakes to Avoid

Creating another online profile If the real problem is a forgotten user ID, password, locked account or old mobile number, use the matching recovery route instead.
Withdrawing an ISA to move it Use the formal ISA transfer process when you want to preserve the tax-free ISA wrapper.
Ignoring withdrawal limits Some higher-rate savings accounts limit withdrawals. Read the access rules as carefully as the AER.
Assuming online-only means branch-managed Some accounts have specific digital operating rules. Check the product terms before visiting a branch.
Assuming mortgage porting is automatic A new property and borrower assessment still applies even when the existing deal is described as portable.
Waiting after a missed mortgage payment Contact the payment-support team early. Delaying can make the situation harder to resolve.
Trusting an unexpected login link Open Principality directly rather than entering account details after following an unsolicited email or text link.
Sending sensitive data through a contact form Principality specifically warns customers not to place account or transaction information in its general enquiry message field.
