About 21 Brill Close
21 Brill Close is a three-bedroom semi-detached house in Maidenhead (SL6 3EJ). It has a recorded floor area of 119 m² (around 1281 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (February 2009) shows an E (score 52), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump. The latest certificate is from February 2009, so improvements made since then won't be reflected.
Held since September 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £497,000 sits 80.7% above the 2009 sale of £275,000. On a £-per-square-foot basis, the last sale (£215/sq ft) was about 37.8% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs).
