Conservation rooflights for Dunstable: the essentials
We handle conservation rooflights across Bedfordshire, including Dunstable. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
From Dunstable to Luton, Leighton Buzzard and Flitwick, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Dunstable
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. 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.
