Sun tunnels & tubular skylights in Harrow: what is involved?
Thinking about sun tunnels & tubular skylights in Harrow? 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Harrow is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the HA2 district.

Do you need permission in Harrow?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 Harrow
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.
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.
