18 Marine Gate Mansions, Promenade, Southport, PR9 0AU

18 Marine Gate Mansions is a two-bedroom mid-terrace house in Southport (PR9 0AU). It has a recorded floor area of 89 m² (around 958 sq ft), construction records dating it to 1996-2002 and council tax band E. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. At 89 m² this is the 2nd smallest of 31 units on EPC record in the building, where floor areas span 81–297 m². The building's EPC ratings span D to B across 31 units on file. The latest certificate (June 2014) shows a C (score 77), near the top of the C band. The recommended improvements would push it to B (score 81). The latest certificate is from June 2014, so improvements made since then won't be reflected.

At 89 m² it sits well below the postcode median (159 m² across 30 EPCs), making it one of the more compact homes locally. Across 2019–2022, sale prices on this property compounded at 2.6% per year. Today's modelled estimate of £188,000 is 17.5% above the 2022 sale price. Most recent transfer: February 2022 at £160,000. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend.
