Overview

About 17 Blenheim House

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

17 Blenheim House is a property in Southwark, London, London (SE1 2SF). It has a recorded floor area of 52 m² (around 560 sq ft). The latest certificate (August 2016) returns a high B (score 86), putting the home a stone's throw from an A rating. The latest certificate is from August 2016, so improvements made since then won't be reflected. At 52 m² this is the 2nd smallest of 32 units on EPC record in the building, where floor areas span 40–416 m². The building's EPC ratings span C to B, with this unit at the top.

Today's modelled estimate of £418,000 is 60.2% below the 2017 sale of £1,050,922, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£1,878/sq ft) was about 30.5% below the postcode norm. At 52 m² it sits well below the postcode median (121 m² across 31 EPCs), making it one of the more compact homes locally. Last sold in June 2017, so it's been off the market for around 9 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 17 Blenheim House is modelled from its 52 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SE1 2SF. 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 17 Blenheim House. 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 17 Blenheim House was lodged in August 2016 at band B and expired in August 2026, 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 17 Blenheim House. 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 104 schools and 30 stops listed are measured in a straight line from SE1 2SF, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
