28 Regency Apartments, Citadel East, Killingworth, Newcastle Upon Tyne, NE12 6DL

28 Regency Apartments is a two-bedroom mid-terrace house in Killingworth, Newcastle Upon Tyne, Newcastle Upon Tyne (NE12 6DL). It has a recorded floor area of 55 m² (around 595 sq ft), construction records dating it to 2003-2006 and council tax band A. The latest certificate (February 2012) shows a C (score 77), near the top of the C band. The rating has held steady at C across 2 certificates since February 2009. Between certificates, main heating went from Very Poor to Poor. The recommended improvements would push it to B (score 82). Main heating runs on electricity. The latest certificate is from February 2012, so improvements made since then won't be reflected. At 55 m² this is the 41st smallest of 50 units on EPC record in the building, where floor areas span 40–64 m². The building's EPC ratings span D to B across 50 units on file.

Today's modelled estimate of £103,000 is 24% below the 2005 sale of £135,500, an unusual pattern given regional price growth and worth checking against the EPC condition. Held since June 2005 — that's 21 years off the open market, well above the local norm.
