What does skylight installation in Bolton involve?
Thinking about skylight installation in Bolton? 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for skylight installation include builders' projects and retrofits into finished roofs.
Neighbouring towns include Farnworth (4 km) and Westhoughton (7 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Supply and fit
- Internal plaster reveal
- New openings with joist trimming
- Fit only (customer-supplied units)
- Upstands and flashings
- New openings in existing roofs
- Fit-only for units you have bought
What to check first
- Structural changes may need an engineer's check
- Work at height is planned with suitable access
Consents for skylight installation in Bolton
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about skylight installation in Bolton
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.
Is the survey free?
Yes, for new installations. Repair visits are charged.
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.
Do I need to be at home for the survey in Bolton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Bolton?
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.
