What do sun tunnels & tubular skylights involve?
Sun tunnels & tubular skylights in Buckinghamshire 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. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

Planning and building rules in England
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. 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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

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
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.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Can it work at night?
Some models include a light fitting in the diffuser.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do I need to be at home for the survey in Buckinghamshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
