Warmer front rooms on 1930s and Victorian homes. A bay window projects out from the wall in angled sections; a bow window curves in more, shallower sections.

Winter light and glass choice in Bow

Winter days in Bow are short: about 7 h 49 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 bay and bow windows 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

The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
