How we approach skylight installation in Prescot
Thinking about skylight installation in Prescot? The short answer: survey, supply and fit — new openings, extensions and fit-only work. The longer answer depends on your roof, which is why we survey before we price.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Think of skylight installation for new extensions, new openings and fit-only jobs.
From Prescot to Huyton, St Helens and Halewood, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight installation in Prescot
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.

Common questions
Is the survey free?
Yes, for new installations. Repair visits are charged.
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.
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.
Can you work alongside my builder in Prescot?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Prescot?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
