Sash window prices
New sash windows in Chelsea typically start from around £2,650 plus VAT for a standard box sash window. The final price will depend on the window size, timber, glazing, ironmongery, finish and any additional detailing required.
Our windows are made using premium timber, including hardwood and Accoya, with double glazing and draught proofing included in the specification. Traditional features such as glazing bars, architraves and ironmongery can be matched to suit the property.
We provide a free survey and a clear written quotation explaining what is included. There is no obligation and no hidden installation charge.
Planning and conservation
Many properties in Chelsea are within conservation areas, so replacement windows must preserve the appearance and character of the building. This usually means paying close attention to the timber, frame proportions, glazing bars and opening style.
The Royal Borough of Kensington and Chelsea allows certain residential windows to be replaced without a separate planning application where the new windows are of a similar appearance and meet the relevant conditions. Different rules apply to listed buildings, so homeowners should check the status of their property before work begins.
We design new timber sash windows to suit period properties, with careful attention to the original style and detailing.

Whether new sash windows are a better option than repairing existing windows in Chelsea depends on the condition of the current frames. Many original sash windows can be repaired where the timber remains structurally sound. However, where decay is extensive or long-term performance is a priority, new sash windows often provide better value, improved insulation, and smoother operation.
