Triple glazing for period homes and conservation areas in Heston
We arrange surveys and fitting of period-style triple glazing in Heston and the TW5 area, with a written, fixed quote after a free survey.
Warmth for period homes without losing their character. In a conservation area, replacing windows on a house is often permitted development if the new windows look similar to the old ones, but councils can remove those rights with an Article 4 direction.
Winter light and glass choice in Heston
In Heston, midday sun in late December sits around 15° high, with roughly 7 h 50 min of daylight. For windows facing north or shaded by neighbours, cutting heat loss matters more than solar gain; on open south-facing glass, ask about a higher solar-gain unit.

Rules for period homes and conservation areas in England
In England, replacement windows must meet 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
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.

Questions from Heston
Can I put triple glazing in a listed building?
Usually not as a replacement. Listed building consent is needed and is often refused for original windows. Secondary glazing is the common alternative.
Can I have triple glazing in a conservation area?
Often yes, if the new windows match the look of the old ones and there is no Article 4 direction. Check with your council first.
How long does it take to get period-style triple glazing fitted in Heston?
After the survey, typical manufacture time is 6 to 10 weeks, and most homes are fitted in 1 to 4 days.
