Winter light across Kent
Our 23 local town pages in Kent run from Folkestone in the south to Dartford in the north. On the shortest day, daylight ranges from about 7 h 50 min in Dartford to 7 h 54 min in Folkestone, and the midday sun reaches between 15° and 16°.
Maidstone 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 52 min of daylight on 21 December. Triple glazing pays back most here on north-facing and shaded rooms.

Rules in England
The rules for replacement windows in England are set by Approved Document L (2021 edition, with 2023 amendments): 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
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.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
