Triple glazing for period homes and conservation areas in Berkhamsted
We arrange surveys and fitting of period-style triple glazing in Berkhamsted and the HP4 area, with a written, fixed quote after a free survey.

Heritage-style frames and plain advice on consents. 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 Berkhamsted
By midsummer Berkhamsted has about 16 h 41 min of daylight, but in December only around 7 h 47 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for period homes and conservation areas in England
England requires replacement windows to achieve 1.4 W/m²K, or a Window Energy Rating of band B or better, which good triple glazing passes comfortably. 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.
