Common property types

• 1930s semi-detached houses: The defining property type in West Wickham. Streets such as Wickham Court Road, The Avenue, Highfield Drive, and Links Way are lined with three-bedroom semis built between 1928 and 1938. These houses have cavity brick walls, front bay windows, hipped roofs with ridge tiles, and suspended timber ground floors. Most have had replacement uPVC double glazing fitted over the years. The cavity behind the front bay is a well-known EPC weak spot, as it is narrower than the main walls and was often missed when cavity wall insulation was installed elsewhere in the property.
• Detached houses on larger plots: Bigger detached properties are found along Corkscrew Hill, Wickham Way, and in the Coney Hall area. These four and five-bedroom houses from the 1930s sit on generous plots with long gardens. Many have been extended at the rear or into the loft over the years. Mixed construction types from different building phases need to be recorded carefully during an EPC. The larger heated volume of these properties means they are more sensitive to insulation gaps.
• Coney Hall estate: The Coney Hall development to the south of West Wickham was built in the late 1930s and features a mix of semi-detached and detached houses, many with tile-hung or rendered upper storeys. The distinctive design of these properties means that construction details can vary from house to house. Tile-hanging and render need to be assessed to determine whether there is a cavity behind them or whether they sit on solid walls, as this significantly affects the EPC rating.
• Post-war infill housing: Some smaller developments from the 1950s and 1960s fill gaps between the main 1930s estates. These include short terraces, semi-detached pairs, and occasional bungalows. Construction is typically cavity brick with concrete tile roofs. These properties tend to have simpler layouts than the 1930s stock and can score slightly better on EPCs where cavities are filled and heating systems are up to date.
• Modern apartment blocks: A small number of newer apartment developments have been built near West Wickham station and along the High Street. These are constructed to modern building standards and typically achieve B or C ratings. They still need an EPC for every sale or letting.

Typical EPC issues we find in West Wickham

• Unfilled cavity walls: Many 1930s semis in West Wickham have never had their cavity walls filled. This is the single most impactful improvement available for most properties and can shift a rating by one or two bands on its own.
• Bay window cold bridges: The front bay window is a feature of almost every 1930s semi in West Wickham. The narrower cavity behind the bay was frequently skipped when the main walls were insulated, creating a cold bridge that reduces the overall wall insulation score on the EPC.
• Suspended timber floors: The ground floors of 1930s semis have airbricks and ventilated voids underneath. Very few properties in West Wickham have had underfloor insulation fitted, and it is one of the most consistently recommended improvements on local EPC reports.
• Loft conversions without certification: West Wickham has a high rate of loft conversions. Where building control documentation cannot be produced to verify insulation levels between the room and the roof slope, the assessment must assume minimal insulation, which pulls the rating down.
• Ageing boilers: Some properties still have boilers from the early 2000s or older. Replacing a boiler over 15 years old with a modern condensing model improves both the EPC rating and the actual running costs of the property.
