Sun tunnels & tubular skylights in Towcester: what is involved?
Sun tunnels & tubular skylights in Towcester means light pipes that bring daylight to halls and bathrooms with no window. We cover the NN12 district and the rest of Northamptonshire, with a survey before any price is fixed.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. In Towcester, as anywhere, sun tunnels & tubular skylights are the usual choice for windowless hallways, landings and bathrooms.
Towcester is around 15 km from Northampton, and we survey and fit throughout that part of Northamptonshire, including the NN12 district.

Planning, building control and Towcester
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sun tunnels & tubular skylights in Towcester
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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Do I need to be at home for the survey in Towcester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Towcester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
