Overview

About 21a

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

21a is a detached house in Southwick, Brighton, Brighton (BN42 4AD). It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (December 2018) shows a D (score 66), on the cusp of jumping into the C band. Earlier certificates rated it C (August 2012); the latest reading is one band lower. Between certificates, wall efficiency dropped from Good to Poor and window efficiency dropped from Poor to Very Poor. The recommended improvements would push it to C (score 74). At 96 m² this is the 4th smallest of 11 units on EPC record in the building, where floor areas span 42–232 m². The building's EPC ratings span F to C across 11 units on file.

Today's modelled estimate of £307,000 is 38.6% below the 2016 sale of £500,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look.

How 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
The estimate for 21a is modelled from its 96 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in BN42 4AD. 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 21a. 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 21a was lodged in December 2018 at band D and is valid until December 2028. 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 21a. 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 14 months, which places each incident at an approximate point. The 15 schools and 30 stops listed are measured in a straight line from BN42 4AD, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21a 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.
