Overview

About 20a

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

20a is a mid-terrace house in London (SE18 1RL). It has a recorded floor area of 16 m² (around 172 sq ft) and construction records dating it to 1930-1949. At 16 m² this is the 3rd smallest of 4 units on EPC record in 20a, where floor areas span 15–21 m². The building's EPC ratings span D to C, with this unit at the bottom. The latest certificate (July 2026) shows a D (score 65), on the cusp of jumping into the C band. Earlier certificates rated it C (August 2020); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Good; while lighting dropped from Very Good to Good and main heating dropped from Average to Poor. The recommended improvements would push it to C (score 77). Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.

At 16 m² it sits well below the postcode median (65 m² across 76 EPCs), making it one of the more compact homes locally.
