Sun tunnels & tubular skylights for Gainsborough: the essentials
For Gainsborough homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Gainsborough is around 23 km from Lincoln, and we survey and fit throughout that part of Lincolnshire, including the DN21 district.
Specification options
- Pitched or flat-roof flashings
- Insulated tube sections
- Rigid (brighter) or flexible tubes
- Diffusers in several sizes
- Ventilation adaptor
- Optional ventilation or lighting kit on some models
- Works on pitched and flat roofs
Things we check at survey
- Tube runs need insulation in cold lofts to limit condensation
- Gives light, not a view
Planning and building rules for Gainsborough
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sun tunnels & tubular skylights in Gainsborough
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.
Is the survey in Gainsborough free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Gainsborough?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
