Overview

About 21 Balgowan Street

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

21 Balgowan Street is a three-bedroom mid-terrace house in Greenwich, London, London (SE18 1EB). It has a recorded floor area of 12 m² (around 129 sq ft), construction records dating it to 1900-1929 and council tax band C. At 12 m² this is the smallest unit on EPC record across the building (12–125 m²). The building's EPC ratings span E to C, with this unit at the top. Period features are noted in the property record. Our model identifies extension potential, subject to local planning policy. The latest certificate (June 2026) shows a C (score 69), just inside the C band. When first surveyed in April 2010 the rating was E, the property has climbed 2 bands since. Between certificates, window efficiency dropped from Average to Very Poor and hot-water efficiency dropped from Good to Very Poor. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.

At 12 m² it sits well below the postcode median (79 m² across 12 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the top 10% of properties in this postcode. Across 2012–2015, sale prices on this property compounded at 26.3% per year. Today's modelled estimate of £345,000 is 13.1% above the 2015 sale price. On a £-per-square-foot basis, the last sale (£2,361/sq ft) was about 1736.8% above the typical sold price in the postcode. Last sold in September 2015, so it's been off the market for around 11 years.

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 21 Balgowan Street is modelled from its 12 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in SE18 1EB. 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 Balgowan 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 21 Balgowan Street was lodged in June 2026 at band C and is valid until June 2036. 3 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 Balgowan 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 17 months, which places each incident at an approximate point. The 51 schools and 30 stops listed are measured in a straight line from SE18 1EB, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Balgowan 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.
