Loft conversion skylights for Hornchurch: the essentials
We handle loft conversion skylights across Greater London, including Hornchurch. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Hornchurch, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
Hornchurch is around 24 km from central London, and we survey and fit throughout that part of Greater London, including the RM11 district.

Consents for loft conversion skylights in Hornchurch
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. 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.
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.

Common questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
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.
Is the survey in Hornchurch free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Hornchurch?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
