Bespoke & shaped rooflights for Portsmouth: the essentials
We handle bespoke & shaped rooflights across Hampshire, including Portsmouth. 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of bespoke & shaped rooflights for openings that standard sizes do not fit.
Portsmouth is around 25 km from Southampton, and we survey and fit throughout that part of Hampshire, including the PO1 district.

Consents for bespoke & shaped rooflights in Portsmouth
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
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.
How do I book a survey in Portsmouth?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
