Daylight in Forest Hill and what it means for your glass
In Forest Hill the shortest day has roughly 7 h 50 min of daylight and the longest about 16 h 38 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.
How it works in Forest Hill
Start with a guide price online or by phone. A surveyor then measures your opening in Forest 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
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
