Sun tunnels & tubular skylights in Flitwick: what is involved?
Thinking about sun tunnels & tubular skylights in Flitwick? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Flitwick, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.

Planning and building rules for Flitwick
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. 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.
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. 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.
Read the planning permission guide before you commit to a design.
