About 1a
1a is a detached house in Monmouth (NP25 3BR). It has a recorded floor area of 79 m² (around 855 sq ft) and construction records dating it to before 1900. The latest certificate (March 2010) shows an F (score 34), near the bottom of the EPC scale. The recommended improvements would push it to E (score 47). Main heating runs on electricity. The latest certificate is from March 2010, so improvements made since then won't be reflected. At 79 m² this is the 13th smallest of 18 units on EPC record in the building, where floor areas span 38–142 m². The building's EPC ratings span G to C across 18 units on file.
At 79 m² the property is well over the postcode median (50 m² across 17 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
