Get started1a is a five-bedroom detached house in Great Harrowden, Wellingborough, Wellingborough (NN9 5AF). It has a recorded floor area of 222 m² (around 2390 sq ft) and construction records dating it to 1991-1995. The latest certificate (December 2015) shows a D (score 63), on the cusp of jumping into the C band. When first surveyed in July 2013 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Good to Very Good, hot-water efficiency went from Very Poor to Poor and lighting went from Very Poor to Poor. The recommended improvements would push it to C (score 74). Main heating runs on oil. The latest certificate is from December 2015, so improvements made since then won't be reflected. The home occupies a corner plot.
Held since February 1997 — that's 29 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £641,000 sits 292% above the 1997 sale of £163,500.
