About Clarendon House
Clarendon House is a one-bedroom mid-terrace house in Northampton (NN1 1NS). It has a recorded floor area of 48 m² (around 517 sq ft) and construction records dating it to 1976-1982. At 48 m² this is the 6th smallest of 19 units on EPC record in Clarendon House, where floor areas span 46–64 m². The building's EPC ratings span D to B, with this unit at the bottom. The latest certificate (April 2016) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 77). Main heating runs on electricity. The latest certificate is from April 2016, so improvements made since then won't be reflected.
Held since June 2002 — that's 24 years off the open market, well above the local norm. Across 2001–2002, sale prices on this property compounded at 11.2% per year. Today's modelled estimate of £120,000 sits 86% above the 2002 sale of £64,500. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs).
