Overview

About 18 Allison Grove

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

18 Allison Grove is a detached house in Southwark, London, London (SE21 7ER). It has a recorded floor area of 153 m² (around 1644 sq ft), construction records dating it to 1930-1949 and council tax band G. The latest certificate (March 2009) shows an F (score 27), near the bottom of the EPC scale. The recommended improvements would push it to E (score 54). The latest certificate is from March 2009, so improvements made since then won't be reflected.

Held since May 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £1,647,000 sits 153.4% above the 2009 sale of £650,000. On a £-per-square-foot basis, the last sale (£395/sq ft) was about 19.5% below the postcode norm. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, a loft conversion and new windows, meaningful when judging how the property has evolved.

Method

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 18 Allison Grove is modelled from its 153 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SE21 7ER. 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. 1 sale is recorded for 18 Allison 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 18 Allison Grove was lodged in March 2009 at band F and expired in March 2019, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. 3 applications are matched to 18 Allison 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 18 months, which places each incident at an approximate point. The 63 schools and 30 stops listed are measured in a straight line from SE21 7ER, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 Allison Grove is in council tax band G. 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.
