Overview

About Flat 1

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

Flat 1 is a three-bedroom end-of-terrace house in London (SE1 1DB). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1950-1966 and council tax band C. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. At 66 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 61–66 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (August 2015) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 81), a 2-band jump. The latest certificate is from August 2015, so improvements made since then won't be reflected.

At 66 m² the property is well over the postcode median (33 m² across 19 EPCs), placing it in the larger end of the local stock. Last sold in March 2016, so it's been off the market for around 10 years. Across the public record there are 4 sales, relatively high churn for a single property. Across 1998–2016, sale prices on this property compounded at 10.2% per year. On a £-per-square-foot basis, the last sale (£985/sq ft) was about 74.7% above the typical sold price in the postcode.

Valuation method in detail

How the estimate is made: The estimate for Flat 1 is modelled from its 66 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in SE1 1DB. 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. 4 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 August 2015 at band D and expired in August 2025, 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. None is 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 17 months, which places each incident at an approximate point. The 97 schools and 30 stops listed are measured in a straight line from SE1 1DB, 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 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.
