About 20 Blenheim House
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
20 Blenheim House is a two-bedroom property in Southwark, London, London (SE1 2SF). It has a recorded floor area of 92 m² (around 990 sq ft). There is a swimming pool on the plot, uncommon for the area. Other recorded features include a balcony. At 92 m² this is the 12th 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. The latest certificate (August 2016) returns a high B (score 85), 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.
Today's modelled estimate of £1,109,000 is 64.1% below the 2017 sale of £3,090,000, below the original sale price, which typically signals condition or completion-status changes worth verifying. On a £-per-square-foot basis, the last sale (£3,120/sq ft) was about 18.3% above the typical sold price in the postcode. Last sold in April 2017, so it's been off the market for around 9 years. At 92 m² it's 24% smaller than the typical home in the postcode (121 m² median across 31 EPCs).

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 20 Blenheim House is modelled from its 92 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in SE1 2SF.

- 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 20 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 20 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.
