Winter light across Hertfordshire
Our 18 local town pages in Hertfordshire run from Rickmansworth in the south to Letchworth Garden City in the north. On the shortest day, daylight ranges from about 7 h 44 min in Letchworth Garden City to 7 h 48 min in Watford, and the midday sun reaches between 15° and 15°.
Watford 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 48 min of daylight on 21 December. Triple glazing pays back most here on north-facing and shaded rooms.

Rules 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.
