Skylight installation for Marlborough: the essentials
Skylight installation in Marlborough means survey, supply and fit — new openings, extensions and fit-only work. We cover the SN8 district and the rest of Wiltshire, with a survey before any price is fixed.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of skylight installation for new extensions, new openings and fit-only jobs.
Neighbouring towns include Swindon (16 km) and Devizes (20 km). We offer a survey date when we reply to your enquiry.

Consents for skylight installation in Marlborough
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Is the survey free?
Yes, for new installations. Repair visits are charged.
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 in Marlborough free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Marlborough?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
