About 21 Dolphin Court
21 Dolphin Court is a two-bedroom property in Frinton On Sea (CO13 9PB). It has a recorded floor area of 61 m² (around 657 sq ft), construction records dating it to 1950-1966 and council tax band C. Tenure is freehold. At 61 m² this is the smallest unit on EPC record across the building (61–88 m²). The building's EPC ratings span D to C, with this unit at the bottom. Other recorded features include a balcony and notable views. The latest certificate (December 2025) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 78). This certificate was lodged in the last six months, so the rating reflects current condition.
It hasn't traded since January 1997, a hold of 29 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £245,000 sits 315.3% above the 1997 sale of £59,000. On a £-per-square-foot basis, the last sale (£90/sq ft) was about 61.2% below the postcode norm. At 61 m² it's 19.3% smaller than the typical home in the postcode (76 m² median across 13 EPCs).
