About Boundary House
Boundary House is a detached house in Elstree, Borehamwood, Borehamwood (WD6 3JP). It has a recorded floor area of 96 m² (around 1039 sq ft) and construction records dating it to 1967-1975. The latest certificate (February 2009) shows an F (score 27), near the bottom of the EPC scale. The recommended improvements would lift it to D (score 64), a 2-band jump. Main heating runs on electricity. The latest certificate is from February 2009, so improvements made since then won't be reflected.
