Get started18 Stewart Avenue is a three-bedroom semi-detached house in Shepperton (TW17 0EH). It has a recorded floor area of 97 m² (around 1044 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (December 2021) shows an E (score 43), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 81), a 3-band jump. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The home occupies a cul-de-sac position.
One planning record on file: an extension approved in 2022. Past consents include an extension and a porch, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).

That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
