Get started7 Marine Crescent is a three-bedroom semi-detached house in Seaford (BN25 1DA). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (November 2020) returns a B (score 84), comfortably above the UK average. When first surveyed in September 2009 the rating was D, the property has climbed 2 bands since. Between certificates, wall efficiency went from Good to Very Good, roof efficiency went from Average to Very Good and window efficiency went from Average to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would push it to A (score 94). The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal.
