Energy Performance Certificates in Knightsbridge

Common property types

• Victorian Townhouses around Trevor Square: Trevor Square and the adjoining Trevor Place and Trevor Street contain Victorian terraced and semi-detached townhouses built in the 1840s and 1850s. These solid brick properties have been modernised to varying degrees, with some fully refurbished to luxury standards and achieving C ratings, while unrenovated examples with original windows and older boilers typically sit at D.
• Pont Street Red Brick Mansion Flats: The distinctive red brick mansion blocks on Pont Street and Pont Street Mews were built in the 1880s and 1890s in the 'Pont Street Dutch' style. These buildings have solid brick construction with terracotta detailing, and their large, high-ceilinged flats are typically assessed with attention to the roof construction and communal heating arrangements where applicable.
• Egerton Crescent and Egerton Gardens Conversions: Egerton Crescent and Egerton Gardens contain mid-Victorian stucco terraced houses typical of this part of the Chelsea/Knightsbridge boundary. Subdivided into flats of varying sizes, they are within the Knightsbridge and Brompton Conservation Area and are subject to the standard restrictions on window replacement and external insulation.
• Modern Luxury Apartments near Harrods: The streets immediately adjacent to Harrods on Hans Road and Basil Street have seen development of high-specification residential buildings. These contemporary apartments with triple glazing, air source heat pumps and high levels of insulation frequently achieve B ratings and provide a clear contrast to the Victorian stock a few streets away.

Typical EPC issues we find in Knightsbridge

• Conservation Area Restrictions near Brompton Road: Much of the residential stock in Knightsbridge falls within the Knightsbridge and Brompton Conservation Area or the Hans Town Conservation Area. Permitted development for window replacement and external wall insulation is restricted, and assessors note where improvement measures require prior approval.
• High-Specification Heating Systems: Luxury refurbishments in Knightsbridge frequently incorporate multi-zone underfloor heating, smart home integration and combination heat pump and boiler hybrid systems. Correctly recording these systems in RDSAP requires assessors to identify the primary heat generator and fuel type, which can be less straightforward in complex installations.
• Roof Terraces and Altered Roof Structures: High-value property in Knightsbridge has frequently been extended upward, with mansard additions and roof terraces altering the original roof geometry. The insulation status of these additions significantly affects heat loss from upper floors, and assessors must record the construction type and insulation of altered roof sections separately.
• Basement Extensions in Victorian Terraces: The past decade has seen substantial basement excavation beneath Knightsbridge townhouses. New basement floors may have high-quality insulation under their concrete slabs, which can improve the EPC rating compared to an older suspended timber ground floor. Assessors record the floor construction type as observed or as documented.
