Bespoke & shaped rooflights in Catford: what is involved?
We handle bespoke & shaped rooflights across Greater London, including Catford. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for bespoke & shaped rooflights include angled ceilings, corners and architect-designed extensions.
We work across Greater London, including Catford, and in neighbouring towns such as Lewisham and Blackheath. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for bespoke & shaped rooflights in Catford
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. 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.

Common questions
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Will I need planning permission in Catford?
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 Catford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
