Loft conversion skylights for St Albans: the essentials
We handle loft conversion skylights across Hertfordshire, including St Albans. In short: roof windows planned for loft rooms — light, headroom and escape. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In St Albans, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
Neighbouring towns include Harpenden (8 km) and Hatfield (8 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for St Albans
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Loft conversion skylights in St Albans: questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
