Window count and total cost vary by property type. Detached homes typically have 10 or more windows, semi-detached 7 to 8, terraced 5 to 6, and flats 3 to 4.
Why homeowners in Greenwich replace their windows
Energy efficiency. Older double glazing can lose performance as seals, frames and spacer bars age. Modern A-rated units can improve comfort and reduce heat loss when fitted correctly.
Noise reduction. Homes near main roads, rail routes or busy junctions may benefit from acoustic glass or laminated panes. Ask installers to quote the noise-control upgrade separately.
Kerb appeal. Matching the right frame colour, opener pattern and sightlines can make a large difference to the front elevation, especially on terraces, bays and period-style homes.
Window options available in Greenwich
uPVC
Best value for most replacements, with low maintenance and good thermal performance.
Aluminium
Useful for slimmer frames, darker finishes and larger modern openings.
Timber
Best for period character, listed homes or conservation-sensitive replacements.
Composite
A premium option when you want timber style inside with a tougher exterior finish.

Common questions about windows in Greenwich
Do I need planning permission to replace windows in Greenwich?
Most window replacements in Greenwich are permitted development and need no planning permission. The exceptions are listed buildings, homes in a conservation area, and properties under an Article 4 direction, where like-for-like styles or timber frames may be required. Your installer checks this during the free home survey before any work is quoted.
