What are sun tunnels & tubular skylights?
Our sun tunnels & tubular skylights service in Hertfordshire covers light pipes that bring daylight to halls and bathrooms with no window. We survey every job before fixing the price.
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
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
What do sun tunnels & tubular skylights cost in Hertfordshire?
These are typical supply-and-fit ranges. For an address in Hertfordshire, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- 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
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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 Hertfordshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
