Sliding rooflights for Slough: the essentials
Sliding rooflights in Slough means box rooflights whose glass lid slides back for walk-out roof access. We cover the SL1 district and the rest of Berkshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Sliding rooflights suit staircases that rise to a roof terrace.
Neighbouring towns include Windsor (3 km) and Maidenhead (9 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Slough
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sliding rooflights in Slough
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
Do you fit sliding rooflights in Slough?
Yes. We survey and fit sliding rooflights in Slough and across Berkshire. Send your postcode and we will offer a survey date when we reply.
