Get startedFlat 4 is a one-bedroom mid-terrace house in Islington, London, London (N1 3EE). It has a recorded floor area of 46 m² (around 495 sq ft), construction records dating it to 1967-1975 and council tax band C. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Period features are noted in the property record. At 46 m² this is the 2nd smallest of 6 units on EPC record in the building, where floor areas span 37–49 m². The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (February 2026) shows a C (score 77), near the top of the C band. Earlier certificates rated it B (February 2011); the latest reading is one band lower. Between certificates, wall efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Good. This certificate was lodged in the last six months, so the rating reflects current condition.
