What does skylight installation in Corby involve?
Skylight installation in Corby means survey, supply and fit — new openings, extensions and fit-only work. We cover the NN17 district and the rest of Northamptonshire, 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. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
From Corby to Uppingham, Kettering and Oundle, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Corby
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.

Skylight installation in Corby: questions
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Is the survey in Corby free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Corby?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
