Overview

About 45a

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

45a is a one-bedroom end-of-terrace house in Northampton (NN1 4LW). It has a recorded floor area of 186 m² (around 2002 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (May 2026) shows an E (score 51), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since November 2008. Between certificates, hot-water efficiency went from Very Poor to Good; while roof efficiency dropped from Very Good to Average and window efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 71), a 2-band jump. This certificate was lodged in the last six months, so the rating reflects current condition.

At 186 m² the property is well over the postcode median (132 m² across 38 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). On the market in August 2017 and unlisted since — roughly 9 years. Today's modelled estimate of £374,000 is 29% above the 2017 sale price.
