How to Notify Principality Building Society After a Death in the UK
If the person who died had savings, an ISA or a mortgage with Principality Building Society, you should tell Principality as soon as you can. The process is manageable, but it is easier if you understand from the start which forms matter, what documents are needed and which issues can be dealt with before probate is complete.
This guide explains how to notify Principality Building Society after a death in the UK and what families or personal representatives usually need to think about next.
The short answer
To notify Principality Building Society after a death, you normally need to send an official copy of the death certificate and a bereavement registration form. Principality says documents can be taken to a branch, emailed to bereavement@principality.co.uk or posted to its bereavement team in Cardiff.
Before you contact Principality
Gather:
- the full name of the person who died
- their address and date of birth
- the date of death
- any account or mortgage numbers you can find
- an official copy of the death certificate
- your own identification documents if you are not already a Principality member
If you are acting as executor or administrator, say so clearly. If you are the surviving joint account holder or surviving spouse or civil partner, mention that too, because it may affect the path for savings or ISA questions.
How to notify Principality Building Society after a death
Principality's bereavement guidance says you can send the information in three main ways:
- in branch
- by email to bereavement@principality.co.uk
- by post to Principality Buildings, PO Box 89, Queen Street, Cardiff, CF10 1UA
The building society also asks for a Bereavement Registration Form, and its guidance says that form needs a wet signature.
That matters because many families assume everything can be handled fully online. With Principality, it is worth checking exactly which documents can be scanned and emailed and which may still need a signed original.
What documents may be needed
Principality's published bereavement guidance points to several common documents, depending on what you need to do.
These can include:
- the death certificate
- the bereavement registration form
- ID documents for the personal representative or other person dealing with the account
- a bereavement withdrawal request form if money needs to be released for specific expenses
- an account closure form if a savings account is to be closed
If you are not already a Principality member, the society says it may need one name document and one address document. That is routine, but it is worth preparing for so your case does not stall.
What happens to savings accounts
Principality says that once it is notified, a deceased person's savings account will usually be frozen. In practice, that means normal access stops while the building society checks the position and confirms who has authority to act.
That sounds alarming, but it is standard. The important point is that a frozen account does not always mean nothing can be paid out before the estate is fully wrapped up.
According to Principality's bereavement guidance, personal representatives may be able to withdraw money for:
- funeral payments
- inheritance tax
- probate fees
- solicitor certification fees
If you need money for one of those purposes, ask specifically which form Principality wants and whether it pays the amount directly or needs supporting evidence such as an invoice.
ISAs and the Additional Permitted Subscription
If the person who died had an ISA, do not close it blindly without asking about the surviving spouse or civil partner's position.
Principality's bereavement documents mention the Additional Permitted Subscription (APS) process. In simple terms, APS can allow a surviving spouse or civil partner to inherit an extra ISA allowance based on the deceased partner's ISA value.
That does not mean every family will use it, but it is important enough to ask about before the ISA is closed and the paperwork disappears into the wider estate file.
A good question is: Does anyone here need to preserve or apply for APS before we finalise closure?
What happens if there is a mortgage
A mortgage needs more careful handling than a simple savings account.
Principality says interest continues to accrue until the mortgage is repaid, and it says it will write to the personal representative explaining the next steps. It also notes that the route may differ depending on whether the property was owned as joint tenants or tenants in common.
Tell Principality early if:
- the surviving family wants to stay in the property
- the property will be sold
- there is likely to be trouble meeting monthly payments
- there is life insurance that may repay some or all of the balance
These facts change the practical next step. Silence creates delay.
Questions worth asking on the first contact
When you notify Principality Building Society after a death, ask:
- Which products did the person hold with you?
- Which forms do you need for this case?
- Do any forms require a wet signature?
- Can funds be released for funeral or tax costs before probate?
- Is probate required for closure in this case?
- Does the ISA position create an APS option?
- What happens to the mortgage while the estate is being administered?
That list will save time later.
Common mistakes families make
Sending the death certificate without context
A death certificate on its own may not be enough. Include a short covering note explaining who you are, how you can be contacted and what you need done.
Missing the ISA question
Families sometimes focus on closing accounts quickly and overlook the surviving spouse or civil partner's APS position. Ask before anything irreversible happens.
Ignoring the mortgage while dealing with probate
Probate takes time. Mortgage interest does not stop just because the estate paperwork is underway.
Assuming email alone will solve everything
Email is useful, but because Principality highlights a wet-signature requirement on its registration form, always check whether originals are still needed.
A practical checklist
Use this order:
- identify all Principality products
- send death certificate and bereavement registration form
- confirm whether any urgent payments need to be made from the account
- ask about probate requirements
- ask about APS if there is an ISA and a surviving spouse or civil partner
- deal with any mortgage issues immediately
- keep copies of every form and email
If you are handling several organisations at once, put everything in one tracker. A service like GetPassage can help reduce the admin fog by keeping the tasks, documents and next actions together.
The bottom line
To notify Principality Building Society after a death in the UK, send the death certificate and bereavement registration form, confirm what products are involved and ask the society to spell out the next steps for savings, ISAs and mortgages. The process is easier when you ask about urgent payments, probate requirements and APS early rather than discovering them halfway through the estate administration.
