Overview

About Flat 1

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

Flat 1 is a mid-terrace house in Worthing (BN11 3NR). It has a recorded floor area of 20 m² (around 215 sq ft), construction records dating it to before 1900 and council tax band B. At 20 m² this is the smallest unit on EPC record across the building (20–92 m²). The building's EPC ratings span E to C across 5 units on file. The latest certificate (March 2016) shows a D (score 61), on the cusp of jumping into the C band. Earlier certificates rated it C (February 2016); the latest reading is one band lower. Between certificates, wall efficiency dropped from Poor to Very Poor and hot-water efficiency dropped from Good to Very Poor. The recommended improvements would lift it to B (score 85), a 2-band jump. Main heating runs on electricity. The latest certificate is from March 2016, so improvements made since then won't be reflected.

Across 2006–2021, sale prices on this property compounded at 6.9% per year. Today's modelled estimate of £410,000 is 11.8% below the 2021 sale of £465,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£2,160/sq ft) was about 896.2% above the typical sold price in the postcode. 3 planning records sit against the property, 2 approved, 1 refused. The record references listed-building consent, which constrain future alterations. At 20 m² it sits well below the postcode median (86 m² across 54 EPCs), making it one of the more compact homes locally. Most recent transfer: July 2021 at £465,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.

Valuation method in detail

How the estimate is made: The estimate for Flat 1 is modelled from its 20 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in BN11 3NR. 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. 3 sales are recorded for Flat 1. 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 Flat 1 was lodged in March 2016 at band D and expired in March 2026, 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. 3 applications are matched to Flat 1. 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 16 months, which places each incident at an approximate point. The 20 schools and 30 stops listed are measured in a straight line from BN11 3NR, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band: Flat 1 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.
