Sun tunnels & tubular skylights for Penzance: the essentials
Our sun tunnels & tubular skylights service in Penzance 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Penzance, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
From Penzance to Camborne, Redruth and Falmouth, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Penzance
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Insulated tube sections
- Diffusers in several sizes
- Integrated electric light
- Daylight where no window is possible
- Optional ventilation or lighting kit on some models
Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation
- Not a substitute for a habitable-room window
Consents for sun tunnels & tubular skylights in Penzance
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. 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.

Questions about sun tunnels & tubular skylights in Penzance
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
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.

Yes. We survey and fit sun tunnels & tubular skylights in Penzance and across Cornwall. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Penzance?
