About 390 Mill Road
390 Mill Road is a four-bedroom mid-terrace house in Cambridge (CB1 3NN). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to before 1900 and council tax band C. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include a loft. Period features are noted in the property record. The latest certificate (February 2014) shows an E (score 51), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since February 2009. Between certificates, window efficiency went from Poor to Good and main heating went from Average to Good; while lighting dropped from Very Good to Good. The recommended improvements would lift it to B (score 87), a 3-band jump. The latest certificate is from February 2014, so improvements made since then won't be reflected.
Last sale on file: £623,500 in October 2023. Across the public record there are 5 sales, relatively high churn for a single property. 3 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension and a loft conversion, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 90% of similar EPCs). Across 2001–2023, sale prices on this property compounded at 6.8% per year.
