Loft conversion skylights for Slough: the essentials
Thinking about loft conversion skylights in Slough? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
From Slough to Windsor, Maidenhead and Gerrards Cross, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Slough
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do I need to be at home for the survey in Slough?
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 Slough?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
