Overview

About 20 Allerton Road

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

20 Allerton Road is a six-bedroom detached house in Southport (PR9 9NJ). It has a recorded floor area of 358 m² (around 3853 sq ft), construction records dating it to 1900-1929 and council tax band G. The latest certificate (June 2016) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 72), a 2-band jump. The latest certificate is from June 2016, so improvements made since then won't be reflected. The home occupies a corner plot.

At 358 m² the property is well over the postcode median (221 m² across 14 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). 6 bedrooms is on the larger side for this postcode, where 4 is the typical count. Across 1997–2019, sale prices on this property compounded at 4.8% per year. Today's modelled estimate of £723,000 sits 58.9% above the 2019 sale of £455,000. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 22.1% below the postcode norm. One planning record on file: an extension approved in 2021. Past consents include an extension, meaningful when judging how the property has evolved. Sold June 2019 for £455,000.
