How we approach sliding rooflights in Bicester
Our sliding rooflights service in Bicester covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Bicester, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
From Bicester to Oxford, Banbury and Aylesbury, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options

Do you need permission in Bicester?
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. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about sliding rooflights in Bicester
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.
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 Bicester?
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.
Do I need to be at home for the survey in Bicester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
