How we approach loft conversion skylights in Islington
Thinking about loft conversion skylights in Islington? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Loft conversion skylights suit loft conversions and rooms in the roof.
Jobs in Islington are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning, building control and Islington
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
