How we approach sun tunnels & tubular skylights in Kensington
Our sun tunnels & tubular skylights service in Kensington covers light pipes that bring daylight to halls and bathrooms with no window. 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. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
We work across Greater London, including Kensington, and in neighbouring towns such as Notting Hill and Shepherds Bush. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Kensington?
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. 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.

Questions about sun tunnels & tubular skylights in Kensington
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Can you work alongside my builder in Kensington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Kensington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
