Hamilton House is a semi-detached house in King's Lynn (PE32 1QJ). It has a recorded floor area of 167 m² (around 1798 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (March 2023) shows an F (score 34), near the bottom of the EPC scale. The rating has held steady at F across 2 certificates since March 2013. Between certificates, roof efficiency went from Good to Very Good; while hot-water efficiency dropped from Average to Poor and main heating dropped from Poor to Very Poor. The recommended improvements would lift it to C (score 73), a 3-band jump. Main heating runs on electricity.
At 167 m² the property is well over the postcode median (102 m² across 34 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). One planning record on file: an annexe approved in 2021. Past consents include an annexe, meaningful when judging how the property has evolved.
