Winter light in Corby
In Corby, the shortest day brings around 7 h 39 min of daylight, with the midday sun near 14°. Over a heating season of several months, lower heat loss through the glass adds up.
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.
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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Free survey and a written quote fixed for the specification
- Glass build-up and whole-window U-value on every quote

Questions

Most homes are fitted in 1 to 4 days once the windows are made; manufacture takes about 4 to 12 weeks depending on the frame.
Which frame is best for a house in Corby?
It depends on the house rather than the town: uPVC for value, aluminium for slim frames and big panes, timber for period homes, alu-clad timber for low upkeep. Our surveyor will talk through the options.
