Sun tunnels & tubular skylights in Isleworth: what is involved?
For Isleworth homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.
Isleworth sits about 1 km from Hounslow and 3 km from Richmond, and we cover the whole TW7 postcode district and the roads in between.

Planning and building rules for Isleworth
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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sun tunnels & tubular skylights in Isleworth
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.
Can it work at night?
Some models include a light fitting in the diffuser.
Do I need to be at home for the survey in Isleworth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Isleworth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
