Get startedMiddle Flat is a one-bedroom end-of-terrace house in Highworth, Swindon, Swindon (SN6 7AH). It has a recorded floor area of 54 m² (around 581 sq ft), construction records dating it to 1967-1975 and council tax band A. The latest certificate (October 2019) shows a G (score 18), near the bottom of the EPC scale. Earlier certificates rated it B (October 2008); the latest reading is 5 bands lower.
