What do sliding rooflights in Canterbury involve?
Sliding rooflights in Canterbury means box rooflights whose glass lid slides back for walk-out roof access. We cover the CT1 district and the rest of Kent, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of sliding rooflights for walk-out access where a hatch would feel cramped.
From Canterbury to Whitstable, Herne Bay and Faversham, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Canterbury
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
Do I need to be at home for the survey in Canterbury?
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 Canterbury?
Yes. We survey and fit sliding rooflights in Canterbury and across Kent. Send your postcode and we will offer a survey date when we reply.
