How we approach sun tunnels & tubular skylights in Northolt
Thinking about sun tunnels & tubular skylights in Northolt? The short answer: light pipes that bring daylight to halls and bathrooms with no window. 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. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
We work across Greater London, including Northolt, and in neighbouring towns such as Greenford and Harrow. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Insulated tube sections
- Rigid (brighter) or flexible tubes
- Ventilation adaptor
- Pitched or flat-roof flashings
- Diffusers in several sizes
- Low maintenance
- Optional ventilation or lighting kit on some models
Things we check at survey
- Not a substitute for a habitable-room window
- Tube runs need insulation in cold lofts to limit condensation
Planning and building rules for Northolt
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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