Loft conversion skylights for Kingston upon Thames: the essentials
Our loft conversion skylights service in Kingston upon Thames 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for loft conversion skylights include loft conversions and rooms in the roof.
From Kingston upon Thames to Twickenham, Richmond and New Malden, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Kingston upon Thames
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.

Yes — most manufacturers make blinds for each window size.
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 Kingston upon Thames?
