Skylight installation for Chester-le-Street: the essentials
Thinking about skylight installation in Chester-le-Street? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Think of skylight installation for new extensions, new openings and fit-only jobs.
We work across Durham, including Chester-le-Street, and in neighbouring towns such as Washington and Houghton-le-Spring. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for skylight installation in Chester-le-Street
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
