Get startedTrevia is a three-bedroom detached house in Gressenhall, Dereham, Dereham (NR20 4DT). It has a recorded floor area of 86 m² (around 926 sq ft) and construction records dating it to 1967-1975. The latest certificate (March 2022) shows an F (score 31), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 80), a 3-band jump. Main heating runs on oil. Other recorded features include a conservatory. Records show the property has been extended at some point in its history.
At 86 m² it sits well below the postcode median (147 m² across 9 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 89% of similar EPCs). 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. Today's modelled estimate of £523,000 is 23.1% above the 2022 sale price. On a £-per-square-foot basis, the last sale (£459/sq ft) was about 140.7% above the typical sold price in the postcode. Sold August 2022 for £425,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
Trevia's carbon output runs well above what efficient homes in the postcode produce.
