Skylight replacement for Harlow: the essentials
Our skylight replacement service in Harlow covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. In Harlow, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
We work across Essex, including Harlow, and in neighbouring towns such as Hoddesdon and Bishop's Stortford. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for skylight replacement in Harlow
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.
