Get started3 Bayldon House is a one-bedroom detached house in York (YO23 1PZ). It has a recorded floor area of 46 m² (around 495 sq ft), construction records dating it to 2012-2021 and council tax band B. At 46 m² this is the smallest unit on EPC record across the building (46–48 m²). The building's EPC ratings span C to B, with this unit at the bottom. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (December 2025) shows a C (score 79), near the top of the C band. Earlier certificates rated it B (October 2015); the latest reading is one band lower. Between certificates, roof efficiency went from Good to Very Good; while wall efficiency dropped from Very Good to Good and window efficiency dropped from Very Good to Average. This certificate was lodged in the last six months, so the rating reflects current condition.
