Get started17 North Street is a detached house in Mears Ashby, Northampton, Northampton (NN6 0DW). It has a recorded floor area of 166 m² (around 1787 sq ft), construction records dating it to 1950-1966 and council tax band F. The latest certificate (May 2021) shows an E (score 41), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 74), a 2-band jump.
At 166 m² it sits well below the postcode median (248 m² across 8 EPCs), making it one of the more compact homes locally.
