Get started140 Gloucester Avenue is a two-bedroom mid-terrace house in Camden, London, London (NW1 8JA). It has a recorded floor area of 113 m² (around 1216 sq ft) and construction records dating it to before 1900. The latest certificate (February 2026) shows a C (score 80), near the top of the C band. When first surveyed in April 2009 the rating was G, the property has climbed 4 bands since. Between certificates, wall efficiency went from Very Poor to Good, roof efficiency went from Very Poor to Good and window efficiency went from Very Poor to Good. The recommended improvements would push it to B (score 84). This certificate was lodged in the last six months, so the rating reflects current condition. Other recorded features include a basement.
Held since November 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 113 m² the property is well over the postcode median (80 m² across 21 EPCs), placing it in the larger end of the local stock. 5 planning records sit against the property, 4 approved, 1 refused. Past consents include an extension, a basement excavation and change of use to residential, meaningful when judging how the property has evolved. Today's modelled estimate of £1,063,000 is 24.3% above the 2009 sale price.
The EPC has just been inspected, so the rating reflects current condition.
140 Gloucester Avenue has been extended on multiple sides of the property across separate planning applications.
