About 20 Lakeside
20 Lakeside is a four-bedroom detached house in Irthlingborough, Wellingborough, Wellingborough (NN9 5SW). It has a recorded floor area of 99 m² (around 1066 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (May 2012) shows an F (score 24), near the bottom of the EPC scale. Earlier certificates rated it D (October 2010); the latest reading is 2 bands lower. Between certificates, window efficiency went from Average to Good; while hot-water efficiency dropped from Very Good to Average and main heating dropped from Very Good to Very Poor. The recommended improvements would lift it to B (score 81), a 4-band jump. Main heating runs on to be used only when there is no heating/hot. The latest certificate is from May 2012, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.
