Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 40 Mill Road is modelled from its 101 m² EPC floor area, its 7 recorded sales and recent sales of comparable homes in CF15 7JP. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 7 sales are recorded for 40 Mill Road. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 40 Mill Road was lodged in February 2021 at band C and is valid until February 2031. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. None is matched to 40 Mill Road. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
