About 1b
1b is a detached house in Northampton (NN1 4SF). It has a recorded floor area of 268 m² (around 2885 sq ft), construction records dating it to 1900-1929 and council tax band F. The latest certificate (April 2017) shows an F (score 28), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 70), a 3-band jump.
