Sliding rooflights for Sandy: the essentials
For Sandy homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Sandy, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
From Sandy to Biggleswade, St Neots and Bedford, the same survey-first process applies: measure, specify, fix the price, then fit.

Things we check at survey

Planning and building rules for Sandy
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.
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.

Questions about sliding rooflights in Sandy
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Is the survey in Sandy 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 Sandy?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
