Triple glazed fixed and picture windows in Chelsea
Looking at triple glazed fixed and picture windows for a home in Chelsea? We survey, quote and fit across Greater London, and the SW10 postcode district is part of that.

The best energy performance of any window type: no opening gaps. A fixed or picture window does not open; it is one large pane in a slim frame, used to frame a view or bring in light.
Winter light and glass choice in Chelsea
Winter days in Chelsea are short: about 7 h 50 min of daylight on 21 December, with the sun peaking near 15°. That low angle reaches deep into south-facing rooms, so we match the glass to each elevation rather than using one spec for the whole house.

Rules for fixed and picture windows in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a Window Energy Rating of band B or better. Replacement windows are a controlled fitting. A competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council within 30 days; otherwise a building control body approves it.
Before ordering: Replacing windows on a house is normally permitted development if the new ones look similar. New upper-floor windows in a side wall must be obscure glazed and fixed, or open only above 1.7 m. Flats and maisonettes have no householder permitted development rights, so a change that alters their appearance needs planning permission. An Article 4 direction in a conservation area may mean permission is needed, and listed buildings need listed building consent.
How it works
You will know exactly what you are buying: the quote states the unit build-up, frame, finish, fitting work and how Building Regulations compliance is handled. On fitting day each opening is replaced and closed up before the team moves on.

Questions from Chelsea
How heavy is a large triple glazed pane?
Roughly 30 kg per square metre with 4 mm glass, more with thicker or laminated panes. A 3 m by 2 m unit can weigh around 180 kg.
Is a picture window worth triple glazing?
Big panes lose a lot of heat and can feel cold to sit near. Triple glazing keeps the inner pane warmer, which makes the space by the window more comfortable.
Do I need permission for triple glazed fixed and picture windows in Chelsea?
In England, like-for-like replacements on a house are normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
How long does it take to get triple glazed fixed and picture windows fitted in Chelsea?
After the survey, typical manufacture time is 4 to 8 weeks, and most homes are fitted in 1 to 4 days.
