Light and sun in Mill Hill
In Mill Hill the shortest day has roughly 7 h 48 min of daylight and the longest about 16 h 40 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
From guide price to fitted door in Mill Hill
Start with a guide price online or by phone. A surveyor then measures your opening in Mill Hill, checks levels and the lintel, and you receive a fixed written quote. After you approve it, the door is made to measure and fitted, with the compliance certificate sent to you.
Approvals in England
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
