Get started41 Ecton Lane is a detached house in Sywell, Northampton, Northampton (NN6 0BA). It has a recorded floor area of 256 m² (around 2756 sq ft), construction records dating it to 1950-1966 and council tax band E. The latest certificate (November 2025) returns a B (score 82), comfortably above the UK average. When first surveyed in August 2021 the rating was E, the property has climbed 3 bands since. Between certificates, wall efficiency went from Poor to Good, window efficiency went from Average to Good and hot-water efficiency went from Poor to Good. This certificate was lodged in the last six months, so the rating reflects current condition.
At 256 m² the property is well over the postcode median (176 m² across 32 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 81% of similar EPCs). Today's modelled estimate of £864,000 sits 85.8% above the 2021 sale of £465,000. On a £-per-square-foot basis, the last sale (£169/sq ft) was about 21.5% below the postcode norm. 5 planning records sit against the property, 3 approved, 1 refused. Past consents include an extension and partial demolition, meaningful when judging how the property has evolved. Last sale on file: £465,000 in October 2021. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
The EPC has just been inspected, so the rating reflects current condition.
