Bespoke & shaped rooflights in Grantham: what is involved?
Bespoke & shaped rooflights in Grantham means triangular, angled, curved and multi-pane rooflights made to measure. We cover the NG31 district and the rest of Lincolnshire, with a survey before any price is fixed.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. In Grantham, as anywhere, bespoke & shaped rooflights are the usual choice for angled ceilings, corners and architect-designed extensions.
Grantham is around 36 km from Lincoln, and we survey and fit throughout that part of Lincolnshire, including the NG31 district.

Consents for bespoke & shaped rooflights in Grantham
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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