What do sun tunnels & tubular skylights in Chalfont St Peter involve?
We handle sun tunnels & tubular skylights across Buckinghamshire, including Chalfont St Peter. In short: light pipes that bring daylight to halls and bathrooms with no window. 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. Sun tunnels & tubular skylights suit small internal rooms where a full rooflight will not fit.
Jobs in Chalfont St Peter are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Diffusers in several sizes
- Insulated tube sections
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Ventilation adaptor
- Low maintenance
- Daylight where no window is possible
Before you order: points to check
- Tube runs need insulation in cold lofts to limit condensation
- Gives light, not a view
Do you need permission in Chalfont St Peter?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Do I need to be at home for the survey in Chalfont St Peter?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
