Bernwy is a UK software brand helping people who own multiple properties understand their overall financial position. Its platform brings together a user’s home, other properties and related mortgages, showing estimated values, outstanding debt and income in one place. Rather than relying on scattered bank records, agent emails and personal estimates, users can build a clearer picture of what they own and owe.

Bernwy’s tools let users test scenarios using assumptions they choose, such as changes in mortgage rates, a property remaining empty or making mortgage overpayments. The platform can also model longer-term questions, including whether rental income and property equity could support a chosen retirement date. Its calculations are presented as estimates, not forecasts or recommendations, and Bernwy does not advise users to sell, provide financial advice or sell financial products.

The service is designed to help property owners prepare for conversations with brokers, accountants and advisers by understanding their own numbers first.
