French door quotes for Derby homes and gardens
Interwar semis in Allestree, Chaddesden and Littleover typically have narrow openings to the rear garden — French doors fit where bifolds would be too wide. Derby’s Victorian terraces in Normanton also suit French doors, replacing a former sash-and-door back access. Our comparison service pulls three quotes from FENSA or CERTASS installers who work across DE1 to DE24.

Frequently asked questions
Do French doors need planning permission in Derby? For most unlisted homes outside conservation areas, French doors replacing an existing window or door fall under permitted development. Listed and conservation properties (Little Chester, historic centre) need consent from Derby City Council.
Are aluminium French doors worth the extra cost? Aluminium frames are slimmer, stronger and lighter than UPVC, so they suit larger openings without sagging. Expect to pay 30 to 50 percent more than an equivalent UPVC pair. On standard 1,500mm openings, UPVC is often the better value.
Can I replace a rear window with French doors? Yes. If the new opening is the same width or narrower than the existing window, this is usually permitted development. Wider openings that require lintel changes may need building notice under Part A structure regulations.
