About Flat 3
Flat 3 is a mid-terrace house in London (SE1 1DB). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (May 2022) shows a D (score 60), on the cusp of jumping into the C band. When first surveyed in August 2010 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Poor. The recommended improvements would push it to C (score 79). At 66 m² this is the 3rd smallest of 4 units on EPC record in the building, where floor areas span 61–66 m². The building's EPC ratings span D to C, with this unit at the bottom.
It hasn't traded since August 1998, a hold of 28 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 66 m² the property is well over the postcode median (33 m² across 19 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £509,000 sits 297.7% above the 1998 sale of £128,000. On a £-per-square-foot basis, the last sale (£180/sq ft) was about 71% below the postcode norm.
