Between certificates, lighting went from Very Poor to Very Good; while roof efficiency dropped from Average to Poor and hot-water efficiency dropped from Very Good to Good.

Start your researchHow to read this page
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 20 Ash Grove is modelled from its 97 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in HP3 9TL. 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 20 Ash Grove. 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 20 Ash Grove was lodged in February 2012 at band C and expired in February 2022, so a new one is needed to sell or let. 2 certificates are on record, which shows how the home has changed.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 3 applications are matched to 20 Ash Grove. 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 13 months, which places each incident at an approximate point. The 23 schools and 30 stops listed are measured in a straight line from HP3 9TL, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 20 Ash Grove is in council tax band E. 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.
