Sliding rooflights for Horley: the essentials
For Horley homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Sliding rooflights suit staircases that rise to a roof terrace.
We work across Surrey, including Horley, and in neighbouring towns such as Crawley and Redhill. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Horley project
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Rain sensor

- Electric operation with safety stops
What to check first
- Electric units need a dedicated supply and commissioning
- Weight and point loads need a structural check
Planning and building rules for Horley
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.

Sliding rooflights in Horley: questions
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
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.
Will I need planning permission in Horley?
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.
Can you work alongside my builder in Horley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
