Energy Performance Certificates in Wandsworth

Common property types

• Victorian terraces: Found throughout Earlsfield, Southfields, and between the commons. These 1880s-1900s properties have solid brick walls, bay windows, and original features. Many have been extended into loft conversions or rear extensions that may not meet modern insulation standards.
• Battersea mansion flats: Large purpose-built apartment blocks from the late Victorian and Edwardian period, particularly around Battersea Park and Lavender Hill. Thick solid walls, communal entrances, and often communal or district heating systems that require specific EPC assessment.
• Riverside apartments: Modern developments along the Thames from Battersea Power Station to Putney Wharf. These achieve B or C ratings as standard, with efficient construction, double glazing, and modern heating systems.
• 1930s semis in Earlsfield: Pockets of inter-war housing around Earlsfield and Southfields with cavity walls and more conventional construction. These score better than the Victorian stock and respond well to cavity wall insulation and loft insulation.

Typical EPC issues we find in Wandsworth

• Solid walls in period properties: Most of the pre-1919 housing stock has solid brick walls. In terraced streets where houses share party walls, external insulation is rarely practical, and internal insulation reduces room sizes in already compact London homes.
• Communal heating in mansion blocks: Some older mansion blocks have shared boiler systems or district heating. The EPC methodology assesses these differently from individual boilers, and aging communal systems often score poorly.
• Loft conversions without adequate insulation: Many Victorian terraces in Wandsworth have had loft conversions, but older conversions may not have insulation to current standards. The converted loft room scores poorly if the roof slopes are uninsulated.
