Winter light across Greater London

Our 79 local town pages in Greater London run from Coulsdon in the south to Hadley Wood in the north. On the shortest day, daylight ranges from about 7 h 48 min in Enfield to 7 h 52 min in Coulsdon, and the midday sun reaches between 15° and 15°.

Islington sits in the milder south of the UK, so the heating season is shorter than further north, but winter days are still short: about 7 h 49 min of daylight on 21 December. Triple glazing pays back most here on north-facing and shaded rooms.

Rules 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.

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.
