Skylight installation in Westhoughton: what is involved?
Skylight installation in Westhoughton means survey, supply and fit — new openings, extensions and fit-only work. We cover the BL5 district and the rest of Greater Manchester, with a survey before any price is fixed.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Skylight installation suits new extensions, new openings and fit-only jobs.
We work across Greater Manchester, including Westhoughton, and in neighbouring towns such as Atherton and Hindley. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Westhoughton
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
What does skylight installation cost in Westhoughton?
These are typical supply-and-fit ranges. For an address in Westhoughton, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.
| Option | Guide price inc VAT | Ex VAT |
|---|---|---|
| New opening in an existing roof, supply and fit | £2,395 – £5,395 | £1,995 – £4,495 |
| Supply and fit into a new extension Typical | £1,435 – £3,595 | £1,195 – £2,995 |
| Fit only, customer-supplied unit | £595 – £1,195 | £495 – £995 |
The process, step by step
- Tell us what you have. Send the BL5 postcode, a rough size and a couple of photos.
- Survey. We measure the opening, check the roof build-up and agree the options.
- Written price. You receive a fixed price listing the unit, the work and the lead time.
- Installation day. Usually one day into a prepared opening, longer for new openings.

Questions about skylight installation in Westhoughton
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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 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.
