Rear slope Velux windows within permitted development limits do not require planning permission on most Kings Worthy properties. Principal elevation (street-facing) windows and any Velux on listed buildings require consent. We confirm the planning position at the free survey visit.

The correct Velux size depends on your rafter spacing, the available roof height between eaves and ridge, and what the window is for. We survey and recommend the appropriate size for your specific Kings Worthy property. Most Kings Worthy 1970s–80s chalk ridge estates properties suit CK02 or FK06 as the primary size.

A single Velux on an accessible pitch: 3–5 hours. Two windows same day on most Kings Worthy properties. Where structural trimming is required (opening spanning more than one rafter), allow 1–2 hours additional.

Incorrect flashing is the most common cause of Velux leaks. We always use the manufacturer-specified tile flashing kit for the specific tile profile on your Kings Worthy property — not a generic kit. This is the single most important quality variable in Velux installation.

Yes — Velux supplies tile-specific flashing kits for all common tile profiles including the 1970s–80s chalk ridge estates tiles typical in Kings Worthy. We confirm the correct kit at survey stage before ordering.

Yes — where the Velux opening requires a structural trimming header, we carry out this work as part of the installation. The structural requirement is confirmed at survey and included in the written quote.

For habitable room loft conversions in Kings Worthy, building regulations require minimum window area (1/20th of floor area) and Part L thermal performance compliance. For non-habitable loft windows, building regulations do not typically apply. We confirm the specific requirements for your Kings Worthy project at survey.

Modern Velux GGL and GGU windows pivot 180° for external glass cleaning from inside. This is the correct method — we do not recommend accessing the tile surface around the window for cleaning.

Velux manufacturer warranty: 10 years on the window and 20 years on glazing. Our workmanship guarantee covers the installation including flashing and tile redress for 10 years. Both warranties apply to your Kings Worthy installation.
