Get started20 Chilbolton Avenue is a four-bedroom detached house in Winchester (SO22 5HD). It has a recorded floor area of 226 m² (around 2435 sq ft), construction records dating it to 1950-1966 and council tax band G. The latest certificate (December 2011) shows a D (score 65), on the cusp of jumping into the C band. The latest certificate is from December 2011, so improvements made since then won't be reflected.

It lags the bulk of the postcode on energy efficiency (less efficient than 86% of similar EPCs). 3 planning records sit against the property, 3 approved, 0 refused. Past consents include tree works and an extension, meaningful when judging how the property has evolved. The record references listed-building consent, which constrain future alterations.
