Newcastle Building Society is a member-owned UK mutual with a strong regional presence across the North East, Cumbria and North Yorkshire. Its core consumer services include savings, Cash ISAs, Lifetime ISAs, residential mortgages and face-to-face branch support.
Unlike a shareholder-owned bank, a mutual is owned by its qualifying members. Most Newcastle Building Society share-account holders have membership rights under the Society’s rules.

Newcastle Building Society Passbook Accounts
Newcastle remains one of the building societies where passbooks still form part of the savings experience. That matters for members who prefer a physical record and branch-based service rather than managing everything through an app.
Passbook may suit you if
- You prefer face-to-face branch transactions.
- You want a physical savings record.
- You do not need app-based account management.
- A suitable branch-based Newcastle savings product meets your needs.
Check before choosing one
- Only qualifying branch-opened accounts can be issued with a passbook.
- The product rate may differ from online savings alternatives.
- Branch opening times become more important.
- The Newcastle savings app does not currently support branch-only/passbook members without an online savings account.

Newcastle Building Society Mortgages
Newcastle offers residential mortgage routes for first-time buyers, home movers and people remortgaging from another lender. The right product depends on affordability, deposit or equity, loan-to-value, property type and the Society’s current lending policy.
Official mortgagesNewcastle Building Society Mortgages

- Use the affordability and Decision in Principle guidance before making a full application.

Newcastle Decision in Principle: What to Prepare
A Decision in Principle gives an indication of how much Newcastle Building Society may be willing to lend based on an initial affordability assessment. It is not the same as a formal mortgage offer.

Existing Newcastle Building Society Mortgage Customers
