Overview

About 4 St Johns Road

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

4 St Johns Road is a two-bedroom semi-detached house in Watford (WD17 1PT). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (September 2022) shows an F (score 36), near the bottom of the EPC scale. Earlier certificates rated it E (May 2017); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Good and roof efficiency went from Very Poor to Average; while hot-water efficiency dropped from Good to Very Poor and main heating dropped from Good to Very Poor.

At 107 m² the property is well over the postcode median (45 m² across 22 EPCs), placing it in the larger end of the local stock.
