3 Cottesbrooke Gardens, Northampton, NN4 0DE

3 Cottesbrooke Gardens is a four-bedroom detached house in Northampton (NN4 0DE). It has a recorded floor area of 98 m² (around 1055 sq ft), construction records dating it to 1996-2002 and council tax band C. The latest certificate (July 2015) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (September 2009); the latest reading is one band lower. Between certificates, lighting went from Very Poor to Very Good; while wall efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 81), a 3-band jump. The latest certificate is from July 2015, so improvements made since then won't be reflected. Other recorded features include a conservatory.

It hasn't traded since February 2000, a hold of 26 years that's notably long for the area. Across 1997–2000, sale prices on this property compounded at 9.1% per year.
