How we approach loft conversion skylights in Winchester
Thinking about loft conversion skylights in Winchester? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
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. Loft conversion skylights suit attic bedrooms, offices and en-suites.
Winchester is around 19 km from Southampton, and we survey and fit throughout that part of Hampshire, including the SO23 district.

Do you need permission in Winchester?
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
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.
Will I need planning permission in Winchester?
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.
