What do sliding rooflights involve?
Across Oxfordshire, our sliding rooflights work covers box rooflights whose glass lid slides back for walk-out roof access. Survey first, fixed price second, fitting third.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement.

Planning and building rules in England
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.
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.
What do sliding rooflights cost in Oxfordshire?
These are typical supply-and-fit ranges. For an address in Oxfordshire, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.
| Option | Guide price inc VAT | Ex VAT |
|---|---|---|
| Large box slider with electric drive | £11,995 – £20,395 | £9,995 – £16,995 |
| Standard box slider Typical | £8,995 – £13,195 | £7,495 – £10,995 |
| Flat sliding lid | £7,195 – £9,595 | £5,995 – £7,995 |
How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common 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.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Do I need to be at home for the survey in Oxfordshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
