Glass balustrade for decking in Greater London
In England, Approved Document K sets minimum guarding heights. In a single-family home, stairs, landings and internal floor edges need at least 900mm, while external balconies, Juliet balconies and roof edges need at least 1100mm. Wales, Scotland and Northern Ireland publish their own guidance, so we check the figure that applies.
Under the guidance used in England, guarding is generally expected where there is a drop of more than 600mm in or around a dwelling, or more than 380mm in other buildings. Below those drops a glass screen is a design choice rather than a requirement, though the glass still has to suit its position.
Toughened glass cannot be cut, drilled or shaped once it has been toughened, so every hole, notch and corner is made before processing. That is why we template on site and order each panel to exact sizes. A panel made to the wrong measurement has to be remade, not trimmed.
Toughened glass can occasionally break without impact because of tiny nickel sulphide inclusions. Heat soak testing to BS EN 14179 reduces that risk by breaking flawed panels in the factory, but it does not remove it entirely, which is one more reason laminated glass is used in guarding.

What applies in Greater London
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
Approved Document K sets minimum guarding heights in England, typically 900 mm for internal stairs and landings and 1100 mm for balconies and external edges of homes. Glass guarding must be designed to resist the loads set out in BS 6180 and the loading standards it refers to.
Parts of Greater London are within about 15 km of the coast, where exposure to wind and salt air is worth planning for. Salt air attacks lower-grade metal fittings and leaves deposits on glass, so balustrades near the coast need hardware and finishes suited to marine exposure, well-drained channels and regular rinsing. Strong onshore wind on exposed balconies also affects the glass and fixing specification.
Flats and town houses often mean carrying long panels through stairwells or lifting them by hand to upper balconies, so panels may need splitting. Parking and loading limits, building management rules and leaseholder consents can all affect when we fit.

Choosing your glass balustrades
Frameless channel system
Laminated toughened glass held in a continuous floor channel, giving a clean edge with no posts. Suits balconies, terraces, decks and modern stairs.
Post and clamp
Glass panels clamped between stainless steel or powder-coated posts. Often uses thinner glass and suits long runs, decking and simpler budgets.
Side-fixed standoffs
Glass fixed to the face of a slab, stair stringer or balcony edge with round standoffs through drilled holes, keeping the walking surface completely clear.
Low-iron glass
Glass with less iron, which removes the green tint seen on the edges of standard glass, most noticeable in thick laminated panels.
Glass Balustrades in Greater London: questions
What happens if a balustrade panel breaks?
With laminated glass, the broken panel is held together by its interlayer and should stay in place until it is replaced. With toughened-only glass, the panel breaks into small pieces and the handrail becomes the barrier. Either way, keep people away from the edge and contact us so we can make the area safe and remake the panel to size.
Does a new glass balustrade need building control approval?
New guarding that forms part of wider building work, such as a new balcony, loft conversion or staircase, is normally checked by building control as part of that project. Whether a standalone replacement needs its own application depends on the work and on the nation, because England, Wales, Scotland and Northern Ireland have separate systems. We can advise at survey.
How thick does the glass in a balustrade need to be?
Glass thickness depends on the fixing system, the panel height and the load the barrier must resist, so there is no single answer. Frameless channel systems commonly use thick laminated toughened glass, such as 21.5mm, while post and clamp systems often use thinner glass. The system maker's tested data sets the minimum, and we specify from that.
How high does a glass balustrade have to be?
In England, the minimum height in a single-family home is 900mm for stairs, landings and internal floor edges, and 1100mm for external balconies, Juliet balconies and roof edges. Other building types have their own heights in the same guidance. Wales, Scotland and Northern Ireland publish separate guidance, so we confirm the figure that applies to your property.
