Skylight installation in Wallington: what is involved?
Thinking about skylight installation in Wallington? 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Skylight installation suits new extensions, new openings and fit-only jobs.
From Wallington to Carshalton, Sutton and South Croydon, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Electrics coordination
- Internal plaster reveal
- New openings with joist trimming
- Upstands and flashings
- Fit only (customer-supplied units)
- New openings in existing roofs
- Free survey for new installations
Before you order: points to check
- Building Regulations approval (a building warrant in Scotland) may be needed
- Fit-only work relies on the product being suitable and complete
Consents for skylight installation in Wallington
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
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.

Can you work alongside my builder in Wallington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
