About 37b
37b is a detached house in Southwark, London, London (SE15 4HX). It has a recorded floor area of 112 m² (around 1202 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (November 2010) shows an E (score 47), well below the UK norm with real room to improve. Earlier certificates rated it D (December 2008); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The latest certificate is from November 2010, so improvements made since then won't be reflected.
At 112 m² the property is well over the postcode median (60 m² across 31 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs). One planning record on file: new windows approved in 2021. Past consents include new windows, meaningful when judging how the property has evolved.
