About 18 Windsor Road
18 Windsor Road is a semi-detached house in Cosham, Portsmouth, Portsmouth (PO6 2TG). It has a recorded floor area of 121 m² (around 1305 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (August 2009) shows an F (score 32), near the bottom of the EPC scale. The recommended improvements would push it to E (score 43). The latest certificate is from August 2009, so improvements made since then won't be reflected.
It hasn't traded since December 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. At 121 m² the property is well over the postcode median (86 m² across 46 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs). Across 1999–2009, sale prices on this property compounded at 9.5% per year. Today's modelled estimate of £329,000 sits 64.5% above the 2009 sale of £199,995.
