How we approach skylight replacement in Andover
Thinking about skylight replacement in Andover? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for skylight replacement include older extensions due a modern rooflight.

Planning and building rules for Andover
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
