The property is a Victorian terrace house built in about 1890 which is located in a local conservation area and has three floors, with 5 double bedrooms, bathroom and 2 shower rooms, 2 reception rooms, a breakfast/dining room, a kitchen and a conservatory. It also has three gardens with a summer house and a garage. Many of the Victorian features have been retained, for example, the original sash windows, doors and bannisters.
When the owners moved into the house in Dec 2009, it had an Energy Performance Certificate in band F with an energy efficiency rating of 30. It now has a D 61 rating with the potential for a C 73 rating, although this would require external wall insulation to be fitted along with floor insulation.
Between 2010 and 2013 the lofts were insulated to current standards, a new central heating system and boiler installed, secondary glazing and draft preventers fitted by CosyHomes, and solar panels fitted by GD Electrical Services. The secondary glazing allowed the sash windows to be retained while at the same time reduce heat loss by about a quarter. This, combined with the solar panels has reduced the owners gas and electricity usage by a third compared to previous usage. Because of the size and configuration of the house roofs the solar panels have had to be fitted in a rather novel way. 4 panels are on the kitchen roof , 3 panels on each of the roofs of the summer house, and 6 panels are on the garage roof which is located on the other side of our private lane away from the house, making a total of 16 panels. All the panels conform to building regulations and the rules pertaining to a conservation area, and are interlinked to create a single entity. The solar PV system includes a solar immersion device which uses excess electricity generated by the PV system to heat the water in the hot water tank, thereby reducing gas usage.
