Sun tunnels & tubular skylights in Grantham: what is involved?
We handle sun tunnels & tubular skylights across Lincolnshire, including Grantham. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Grantham sits about 21 km from Newark-on-Trent and 23 km from Melton Mowbray, and we cover the whole NG31 postcode district and the roads in between.

Do you need permission in Grantham?
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.
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.

Questions about sun tunnels & tubular skylights in Grantham
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 it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Can it work at night?
Some models include a light fitting in the diffuser.
Is the survey in Grantham 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 Grantham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
