Triple glazed composite front doors for homes in Derby: measured on a free survey, made to order and fitted by installation teams working for us across Derbyshire.

Winter light and glass choice in Derby
By midsummer Derby has about 16 h 55 min of daylight, but in December only around 7 h 34 min, with the noon sun at about 14°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for composite front doors in England
England sets replacement door limits through Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.
Planning: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.
How it works

Questions from Derby
Can I have a different colour inside?
Yes, most ranges offer one colour outside and white or another colour inside.
Is triple glazing worth it in a front door?
The glass is the weakest part of a composite door for heat loss, so triple glazing the panels helps most when the door has large glazed areas or side panels.
Do I need permission for triple glazed composite front doors in Derby?
In England, a replacement door on a house that looks similar is normally permitted development; flats need permission if the change alters their appearance, Article 4 areas may need permission, and listed buildings need listed building consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
