About 23 Castle Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
23 Castle Street is a two-bedroom mid-terrace house in Southampton (SO14 6GZ). It has a recorded floor area of 77 m² (around 824 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (October 2010) shows a D (score 65), on the cusp of jumping into the C band. When first surveyed in October 2010 the rating was E, the property has climbed 1 band since. The recommended improvements would push it to C (score 74). The latest certificate is from October 2010, so improvements made since then won't be reflected.

One planning record on file: an extension approved in 2013. Past consents include an extension, meaningful when judging how the property has evolved.

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 23 Castle Street is modelled from its 77 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in SO14 6GZ. 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. 4 sales are recorded for 23 Castle Street. 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 23 Castle Street was lodged in October 2010 at band D and expired in October 2020, 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. 1 application is matched to 23 Castle Street. 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 19 months, which places each incident at an approximate point. The 38 schools and 30 stops listed are measured in a straight line from SO14 6GZ, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 23 Castle Street is in council tax band C. 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.
