It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs.

The latest certificate (November 2023) shows an E (score 43), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since September 2011. Between certificates, window efficiency went from Very Poor to Poor and main heating went from Poor to Average. The recommended improvements would lift it to C (score 69), a 2-band jump. Main heating runs on electricity.

Untraded for 18 years, with the last transfer in May 2008. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 79 m² the property is well over the postcode median (49 m² across 11 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £133,000 is 26.7% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£123/sq ft) was about 36.5% below the postcode norm.
