Overview

About 21 Blakesley Lane

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

21 Blakesley Lane is a one-bedroom mid-terrace house in Portsmouth (PO3 5UG). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to 1991-1995 and council tax band B. The latest certificate (January 2019) shows a C (score 69), just inside the C band. The rating has held steady at C across 2 certificates since December 2008. Between certificates, lighting went from Good to Very Good. The recommended improvements would push it to B (score 91).

Held since February 2007 — that's 20 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2000–2007, sale prices on this property compounded at 12.5% per year. Today's modelled estimate of £209,000 sits 60.8% above the 2007 sale of £130,000. On a £-per-square-foot basis, the last sale (£302/sq ft) was about 31% above the typical sold price in the postcode. At 40 m² it sits well below the postcode median (63 m² across 20 EPCs), making it one of the more compact homes locally.

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 21 Blakesley Lane is modelled from its 40 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in PO3 5UG. 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. 2 sales are recorded for 21 Blakesley Lane. 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 21 Blakesley Lane was lodged in January 2019 at band C and is valid until January 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. None is matched to 21 Blakesley Lane. 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 18 months, which places each incident at an approximate point. The 26 schools and 30 stops listed are measured in a straight line from PO3 5UG, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Blakesley Lane is in council tax band B. 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.
