What do sun tunnels & tubular skylights involve?
Sun tunnels & tubular skylights in Surrey means light pipes that bring daylight to halls and bathrooms with no window. Every quote follows a survey of the roof and the room below.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. 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.

Planning and building rules in England
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.

How the job runs

- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can it work at night?
Some models include a light fitting in the diffuser.
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.
Will I need planning permission in Surrey?
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.
