About 23a
23a is a semi-detached house in London (SE3 7EU). It has a recorded floor area of 91 m² (around 980 sq ft), construction records dating it to 1900-1929 and council tax band C. At 91 m² this is the 18th smallest of 20 units on EPC record in the building, where floor areas span 22–98 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (May 2012) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 78), a 2-band jump. The latest certificate is from May 2012, so improvements made since then won't be reflected.
At 91 m² the property is well over the postcode median (44 m² across 37 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 84% of similar EPCs). One planning record on file: an extension approved in 2022. Past consents include an extension and new windows, meaningful when judging how the property has evolved.
