What the Data Shows
First-home deposit years are measured for England and Wales using a 15% deposit assumption and a 10% annual saving-rate assumption. The data shows England at 11.5 years of saving and Wales at 8.9 years under the same rule. England’s implied deposit is £45.0k, compared with £32.0k for Wales. The result is a MarketStats affordability denominator based on ONS house prices and earnings, not an official ONS deposit-years measure.

Data notes & caveats
This is a transparent affordability measure, not an ONS official deposit metric. Default headline uses a 15% deposit and 10% annual saving rate.
Methodology
Use ONS 2025 median house prices and median full-time workplace earnings. Deposit years = house price × deposit share ÷ (annual earnings × assumed annual saving rate).
Source consistency notes
House prices and earnings come from the same ONS release; the deposit and savings-rate assumptions are MarketStats calculations.
