Questions about the calculator
How accurate are the savings figures?
Every figure comes from a fixed model built from cited public sources and checked to the penny. Results are shown as a range (low, base, high) because outcomes vary property to property. They are estimates to support a decision, not a promise or financial advice. Read the full methodology
Where does the rent data come from?
Monthly rents are official Office for National Statistics medians for your local authority and bedroom count, covering 342 local authorities across England. How the rent lookup works
Are the savings and risk figures added together?
No. Direct savings are cash you keep each year. The risk figures show what is at stake if something goes wrong. They are kept separate and never combined into one headline number. Why we keep them separate
