What do loft conversion skylights in Tonbridge involve?
Our loft conversion skylights service in Tonbridge covers roof windows planned for loft rooms — light, headroom and escape. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
Jobs in Tonbridge are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Planning and building rules for Tonbridge
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.

Questions about loft conversion skylights in Tonbridge
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Can you work alongside my builder in Tonbridge?
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 Tonbridge?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
