flatmate

A flatmate is a person who shares a flat or apartment with one or more others. The term is commonly used in British English and contrasts with roommate in American usage. A flatmate typically shares common areas such as the kitchen, living room, and bathroom, while retaining a private bedroom.

Flatmates may live under a joint tenancy, where all tenants are equally responsible for the rent and obligations, or under a master tenancy with sub-lets. Rent is often split evenly, but arrangements can vary based on room size or access. Tenants usually sign a tenancy agreement and may pay a security deposit, which is protected in a government-approved deposit scheme. Utilities, internet, and sometimes council tax are shared costs, and a written bill-splitting plan is common.

Flatmates have rights to quiet enjoyment and safe, well-maintained housing. Landlords or letting agents are generally responsible for major repairs and compliance with safety regulations. When conflicts arise, clear communication and a written agreement on chores, bills, and privacy can reduce friction. Subletting arrangements should be reviewed to ensure they comply with the tenancy agreement and housing laws.

Changes in flatmate arrangements can occur with new tenants, sublets, or tenancy renewals. The term "flatmate" is more common in the UK and Ireland, while "roommate" is more common in the US; in Australia the term "housemate" is also used.
