Triple glazing for period homes and conservation areas in Thamesmead
If you live in Thamesmead (SE28) and want period-style triple glazing, start with a free survey: every opening measured, then a written quote that fixes the price.
Flush casements and sashes that councils tend to accept. 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 Thamesmead
On the shortest day, Thamesmead gets about 7 h 50 min of daylight and the midday sun reaches only about 15° above the horizon. Low winter sun means north-facing rooms here gain little solar heat, which is where triple glazing’s lower heat loss helps most.

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.
Planning: 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.
