How we approach sliding rooflights in Bexley
Thinking about sliding rooflights in Bexley? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Bexley, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Jobs in Bexley are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Double or triple glazing
- Rain sensor
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Anthracite, black or RAL frames
- Glazed box sides keep the headroom open
- Electric operation with safety stops
Before you order: points to check
- Weight and point loads need a structural check
- The stair opening and headroom must meet Building Regulations
Consents for sliding rooflights in Bexley
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.
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.

Common questions
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.
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.
Will I need planning permission in Bexley?
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.
Is the survey in Bexley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
