What do sun tunnels & tubular skylights in Grimsby involve?
Thinking about sun tunnels & tubular skylights in Grimsby? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we price.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.

Do you need permission in Grimsby?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Will I need planning permission in Grimsby?
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.
Do I need to be at home for the survey in Grimsby?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
