About Hillside
Hillside is a detached house in Clayton, Hassocks, Hassocks (BN6 9PJ). It has a recorded floor area of 145 m² (around 1561 sq ft) and construction records dating it to before 1900. The latest certificate (February 2011) shows an F (score 28), near the bottom of the EPC scale. Main heating runs on electricity. The latest certificate is from February 2011, so improvements made since then won't be reflected.

Past consents include a garage conversion, an annexe, an extension and a loft conversion, meaningful when judging how the property has evolved. The record references listed-building consent, which constrain future alterations. It lags the bulk of the postcode on energy efficiency (less efficient than 73% of similar EPCs).
