Sash windows for Kensington homes

Around Kensington you will mostly find stucco terraces, mansion blocks, mews houses and converted period flats. Victorian and Edwardian terraces often have two-over-two or one-over-one sashes with horns, and matching that pattern exactly keeps the front elevation consistent with neighbouring houses.

In mansion blocks, sash replacement is often controlled by the freeholder or managing agent, so get written approval of the glazing pattern and material before ordering. In conservation areas and on listed buildings, councils may insist on timber sashes or repair rather than replacement, so check with the planning team before choosing materials.

We plan access, parking and building-management requirements before fitting day so the work runs smoothly in busy streets.

Sliding sash windows open vertically and give period homes their familiar look, with balanced sashes, horns and glazing bars. We make replacement sash windows to match original proportions, suiting owners of Victorian, Edwardian and Georgian properties who want better insulation and security without losing traditional character.

  • Traditional look with modern weather sealing
  • Matched to original proportions and glazing bars
  • Smooth vertical sliding operation

Questions from Kensington

Do I need planning permission for sash windows in Kensington?

Large parts of Kensington are covered by conservation areas and many buildings are listed, so we confirm requirements with Kensington & Chelsea Council and the freeholder before quoting. Replacement sash windows on a house are usually permitted development if they look similar, with FENSA covering Building Regulations, but conservation areas with Article 4 directions, listed buildings and flats often need consent.

How soon can you fit sash windows in Kensington?

Lead times vary by product and workload — confirmed with your quote. Being about 10 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.

Will the council allow replacement sash windows in Kensington?

It depends on the property. Houses outside conservation areas usually have permitted development rights for similar-looking windows. In conservation areas with Article 4 directions, on listed buildings and for flats, you may need permission, and some councils require timber. Checking with the planning department before ordering avoids problems later.

Can I see samples before I decide?

Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 10 miles from Kensington. We can also bring samples to your home in Kensington at the free survey.
