Who are Bath Building Society?
As a mutual organisation, Bath Building Society is owned by its saving and borrowing members, not by shareholders. This structure allows it to focus on delivering long-term value and personal service. They are known for their manual, common-sense approach to underwriting, where each application is assessed by a person rather than a computer. This enables them to consider the individual story behind each application, making them a key player in the specialist mortgage market.
What types of mortgages does Bath Building Society offer?
Bath Building Society offers a diverse range of mortgage products, many of which are designed to solve specific borrowing challenges that mainstream lenders may shy away from.
-
Standard Residential Mortgages: For purchasing or remortgaging a primary home, with a focus on individual assessment.
-
Buy for Uni Mortgages: A standout product that allows a student, supported by their parents, to purchase a property for residential use while at university. The parents act as joint borrowers, and the student can rent out spare rooms to generate income.
-
Parent Assisted Mortgages: Designed to help first-time buyers get onto the property ladder by allowing a parent or family member to be a joint applicant on the mortgage, using their income to boost borrowing power.
-
Holiday Let Mortgages: For individuals looking to purchase a property to be used as a short-term holiday rental.
-
Retirement Interest-Only (RIO) Mortgages: Aimed at older borrowers, these mortgages allow applicants to pay just the interest each month, with the capital being repaid when the property is sold, usually upon death or moving into long-term care.
-
Self-Build Mortgages: Providing funding in stages for individuals looking to build their own home.
Bath Building Society's Lending Criteria: Who do they lend to?
The Society's key strength lies in its flexible and pragmatic lending criteria. They have built a reputation for considering applicants with unique circumstances.

Individual Assessment: They do not use automated credit scoring. Their underwriting team reviews every application individually to understand the full picture.
