How we approach loft conversion skylights in Chiswick
Loft conversion skylights in Chiswick means roof windows planned for loft rooms — light, headroom and escape. We cover the W4 district and the rest of Greater London, with a survey before any price is fixed.
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 attic bedrooms, offices and en-suites.
Neighbouring towns include Hammersmith (2 km) and Acton (2 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Chiswick?
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.
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. 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 I add blinds later?
Yes — most manufacturers make blinds for each window size.
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.
Do I need to be at home for the survey in Chiswick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Chiswick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
