What do frameless structural rooflights in Bow involve?
Our frameless structural rooflights service in Bow covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
From Bow to Stratford, Hackney and Leytonstone, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Low-iron extra-clear glass
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Shadow-gap or plastered reveal
- Solar-control coatings
- Double or triple glazed structural units
- Solar-control and low-iron glass options
Things we check at survey
- The internal finish (plaster, shadow gap) is agreed before order
- Large panes need lifting gear and access planning
Do you need permission in Bow?
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Frameless structural rooflights in Bow: questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Will I need planning permission in Bow?
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.
Can you work alongside my builder in Bow?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
