How we approach skylight installation in Sandy
Skylight installation in Sandy means survey, supply and fit — new openings, extensions and fit-only work. We cover the SG19 district and the rest of Bedfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of skylight installation for builders' projects and retrofits into finished roofs.
From Sandy to Biggleswade, St Neots and Bedford, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Sandy
- Fit only (customer-supplied units)

Planning and building rules for Sandy
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. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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.
Can you work alongside my builder in Sandy?
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 Sandy?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
