How we approach loft conversion skylights in Sidcup
Our loft conversion skylights service in Sidcup covers roof windows planned for loft rooms — light, headroom and escape. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of loft conversion skylights for loft conversions and rooms in the roof.

Consents for loft conversion skylights in Sidcup
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about loft conversion skylights in Sidcup
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.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Can you work alongside my builder in Sidcup?
