The building's EPC ratings span C to B, with this unit at the bottom. The latest certificate (July 2026) shows a C (score 78), near the top of the C band. Earlier certificates rated it B (August 2016); the latest reading is one band lower. Between certificates, window efficiency dropped from Good to Average and hot-water efficiency dropped from Very Good to Average. This certificate was lodged in the last six months, so the rating reflects current condition.

Today's modelled estimate of £839,000 is 24.5% below the 2017 sale of £1,111,000, an unusual pattern given regional price growth and worth checking against the EPC condition.

At 57 m² it sits well below the postcode median (121 m² across 31 EPCs), making it one of the more compact homes locally. Last changed hands 9 years ago, in April 2017.
