Rooflights for Welwyn Garden City homes and buildings
Looking for skylights in Welwyn Garden City? We handle survey, supply and fitting for homes and businesses across AL8 and nearby Hatfield and Hertford.
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.
Jobs in Welwyn Garden City are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules in England
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.

Skylight questions: Welwyn Garden City
Will I need planning permission in Welwyn Garden City?
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.
Is the survey in Welwyn Garden City free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do you fit skylights and rooflights in Welwyn Garden City?
Yes. We survey and fit skylights and rooflights in Welwyn Garden City and across Hertfordshire. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Welwyn Garden City?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
