About 23a
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
23a is a two-bedroom semi-detached house in Birkenhead (CH42 1PH). It has a recorded floor area of 71 m² (around 764 sq ft) and construction records dating it to 1900-1929. At 71 m² this is the 6th smallest of 19 units on EPC record in the building, where floor areas span 42–205 m². The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (April 2020) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump.
Held since March 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £116,000 sits 78.5% above the 2009 sale of £65,000. At 71 m² it sits well below the postcode median (140 m² across 18 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).
