How we approach frameless structural rooflights in Rickmansworth
We handle frameless structural rooflights across Hertfordshire, including Rickmansworth. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Frameless structural rooflights suit rooms where you want sky without a visible frame.
We work across Hertfordshire, including Rickmansworth, and in neighbouring towns such as Watford and Chalfont St Peter. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Rickmansworth
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. 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.
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.

Common questions
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.
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 the survey in Rickmansworth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Rickmansworth?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
