Sash windows for N6 homes
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.
On larger period houses with many sashes, prioritise the most draughty or damaged windows first, and record the glazing bar layouts so later phases match exactly. 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.
Window changes in Highgate are closely scrutinised, so we focus on designs with the correct proportions and glazing bars. Archway Road carries the A1 along the eastern side. Our Edmonton factory is about 5.2 miles away.
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.

Questions from N6
Do I need planning permission for sash windows in N6?
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 N6?
Lead times vary by product and workload — confirmed with your quote. Being about 5.2 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Will the council allow replacement sash windows in N6?
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 5.2 miles from N6. We can also bring samples to your home in N6 at the free survey.
