Get started100a is a four-bedroom detached house in New Barnet, Barnet, Barnet (EN4 9QS). It has a recorded floor area of 172 m² (around 1851 sq ft), construction records dating it to 2007 onwards and council tax band G. The latest certificate (June 2015) shows a C (score 73). Earlier certificates rated it B (March 2010); the latest reading is one band lower. Between certificates, hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The latest certificate is from June 2015, so improvements made since then won't be reflected.

At 172 m² the property is well over the postcode median (81 m² across 13 EPCs), placing it in the larger end of the local stock. 8 planning records sit against the property, 7 approved, 1 refused. Past consents include a garage conversion, an extension, solar panel installation and a conservatory, meaningful when judging how the property has evolved.
