6 Semilong Road is a two-bedroom mid-terrace house in Northampton (NN2 6BQ). It has a recorded floor area of 33 m² (around 355 sq ft), construction records dating it to before 1900 and council tax band A.

On EPC score it ranks last in the building (56 versus a best of 78). The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal.

Between certificates, wall efficiency went from Average to Good; while window efficiency dropped from Very Good to Average and hot-water efficiency dropped from Poor to Very Poor. The recommended improvements would push it to C (score 71). Main heating runs on electricity.

It hasn't traded since October 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 33 m² it sits well below the postcode median (69 m² across 11 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs). One planning record on file: subdivision approved in 2011. Past consents include subdivision, meaningful when judging how the property has evolved. Across 2002–2007, sale prices on this property compounded at 10.3% per year. Today's modelled estimate of £128,000 is 21.9% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£296/sq ft) was about 187.6% above the typical sold price in the postcode.
