Hinged roof access rooflights for Tonbridge: the essentials
Our hinged roof access rooflights service in Tonbridge covers hinged glazed hatches over a stair or ladder for roof terrace access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for hinged roof access rooflights include occasional roof access that also lights the stair.
From Tonbridge to Tunbridge Wells, Sevenoaks and Crowborough, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for hinged roof access rooflights in Tonbridge
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.

Common questions
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
Electric or manual?
Gas-strut hatches are simple and reliable. Electric hatches suit heavier lids, wider openings and anyone who would struggle to push a lid up.
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.
Do I need to be at home for the survey in Tonbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
