- How the estimate is made
- The estimate for Mill House is modelled from its 215 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in RH13 8GR. 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. 3 sales are recorded for Mill House. 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 Mill House was lodged in April 2019 at band D and is valid until April 2029. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to Mill House. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 15 months, which places each incident at an approximate point. The 2 schools and 16 stops listed are measured in a straight line from RH13 8GR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- Mill House is in council tax band F. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
