21 Sinclair Drive, Basingstoke, RG21 6AF

21 Sinclair Drive is a two-bedroom mid-terrace house in Basingstoke (RG21 6AF). It has a recorded floor area of 64 m² (around 689 sq ft), construction records dating it to 1996-2002 and council tax band C. The latest certificate (December 2025) returns a B (score 81), comfortably above the UK average. The rating has held steady at B across 3 certificates since June 2009. Between certificates, lighting went from Average to Very Good; while window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Good. This certificate was lodged in the last six months, so the rating reflects current condition. At 64 m² this is the 57th smallest of 83 units on EPC record in the building, where floor areas span 49–122 m². The building's EPC ratings span C to B, with this unit at the top. Other recorded features include a balcony.

It hasn't traded since June 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £208,000 is 40.5% above the 2009 sale price.
