Energy Performance Certificates in Chislehurst

Common property types

• Large Victorian and Edwardian detached houses: The streets around Chislehurst Common, particularly Bromley Road, Manor Park Road, and the roads off Bickley Park, contain substantial Victorian and Edwardian detached houses with solid brick construction, multiple storeys, and period features. These properties typically score E or F on EPC assessments. Solid walls, sash windows, and older heating systems are the main factors limiting energy efficiency. Internal wall insulation is possible but disruptive in large properties with high ceilings and period detail.
• 1920s and 1930s detached: The interwar period brought a wave of large detached houses to roads between Chislehurst and Petts Wood. These have cavity walls and larger plots, making them more treatable than the Victorian stock. Four and five-bedroom properties are common. Some have had significant extensions, loft conversions, and modernisations, which can affect their energy profiles. Cavity fill and boiler upgrades are typically the main recommendations.
• Detached bungalows: A number of bungalows exist on the Chislehurst periphery, particularly toward Elmstead Woods and on quieter residential roads. These are often easier to assess than multi-storey properties. straightforward loft access, single-storey heat loss calculations, and frequently large south-facing gardens that make solar panels a viable recommendation.
• Converted period properties: Some of the larger Victorian and Edwardian houses in Chislehurst have been converted into flats. These conversions inherit the challenges of the original building. solid walls, high ceilings, older glazing. and add the complication of shared communal areas that individual leaseholders cannot easily improve.
• 1950s-60s houses on the Elmstead border: Toward Elmstead Woods and Mottingham, there are pockets of postwar housing including some ex-council stock. These cavity wall properties are more straightforward to assess and improve than the period houses closer to the Common.
• Modern executive houses: Some infill and redevelopment has produced modern executive homes within the BR7 postcode. These typically achieve B ratings from new, though older new-builds from the 1990s and early 2000s may have benefited from updated efficiency standards and can score D or C.

Typical EPC issues we find in Chislehurst

• Solid walls in Victorian properties: The large solid-brick Victorian detached houses around the Common are difficult to improve without significant work. External wall insulation is rarely appropriate on a detached property of this character, and internal insulation is disruptive in high-ceiling rooms.
• Oil-fired heating on larger plots: Some of the more rural-edge properties in Chislehurst, particularly on larger plots toward Green Street Green and Elmstead, still use oil-fired central heating. Oil boilers score lower than gas in RDSAP assessments. Converting to mains gas or a heat pump system is often recommended but is capital intensive.
• Older boilers in 1930s stock: The interwar detached houses often have older gas boilers that have never been replaced. Upgrading to a modern condensing boiler is frequently the single most impactful recommendation on these assessments.
• High ceilings in period properties: Victorian and Edwardian houses in Chislehurst often have ceiling heights of 3 metres or more. This increases the volume of air to heat and worsens the SAP calculation. It is a structural feature that cannot be changed without affecting the character of the property.
• Electric storage heaters in converted flats: Where large houses have been divided into flats, some retain electric storage heating rather than gas central heating. Economy 7 storage heaters score significantly worse than gas in RDSAP. Converting to a gas or heat pump system is the most impactful upgrade available.
