Bespoke & shaped rooflights in Greenwich: what is involved?
Our bespoke & shaped rooflights service in Greenwich covers triangular, angled, curved and multi-pane rooflights made to measure. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Bespoke & shaped rooflights suit openings that standard sizes do not fit.
Greenwich is around 9 km from central London, and we survey and fit throughout that part of Greater London, including the SE10 district.
Options we can specify in Greenwich
- Corner and wrap-around glazing
- Multi-pane butt-jointed runs
- Triangular and trapezoid panes
- Solar-control and low-iron glass

What to check first
- Large panes need a lifting plan
- Longer lead times and no returns on made-to-measure glass
Do you need permission in Greenwich?
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Read the planning permission guide before you commit to a design.
What do bespoke & shaped rooflights cost in Greenwich?
These are typical supply-and-fit ranges. For an address in Greenwich, 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 |
|---|---|---|
| Multi-pane or corner run | £9,595 – £17,995 | £7,995 – £14,995 |
| Single shaped pane, large Typical | £5,395 – £9,595 | £4,495 – £7,995 |
| Single shaped pane, small | £4,195 – £5,395 | £3,495 – £4,495 |
The process, step by step
- Tell us what you have. Send the SE10 postcode, a rough size and a couple of photos.
- Survey. We measure the opening, check the roof build-up and agree the options.
- Agree the quote. You approve the specification and price before anything is ordered.
- Fit and make good. We fit, seal, test and finish the reveal, then hand over the paperwork.

Bespoke & shaped rooflights in Greenwich: questions
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Will I need planning permission in Greenwich?
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.
Can you work alongside my builder in Greenwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
