Bespoke & shaped rooflights in Egham: what is involved?
For Egham homes and buildings we offer bespoke & shaped rooflights: triangular, angled, curved and multi-pane rooflights made to measure. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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 bespoke & shaped rooflights for openings that standard sizes do not fit.
Jobs in Egham 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.

Consents for bespoke & shaped rooflights in Egham
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.
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.
Read the planning permission guide before you commit to a design.

Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Do I need to be at home for the survey in Egham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Egham?
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.
