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
- We don't publish an estimate for 20 Claystones because there is no EPC to tell the model the home's size and specification. The full report sets its records against recent comparable sales in NN4 9UY.
- 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 Claystones. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- There is no Energy Performance Certificate on the public register for 20 Claystones. A valid EPC is needed to sell or let a home in England and Wales, and lasts 10 years.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 20 Claystones. 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 18 schools and 30 stops listed are measured in a straight line from NN4 9UY, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 20 Claystones 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.
