Glass Verandas — UK Starting Prices for 5 Models

What is a glass veranda?

A glass veranda is a covered outdoor structure with a transparent glass roof, supported by aluminium posts and fixed to the side of your home or freestanding in the garden. It creates a sheltered outdoor room that protects you from rain, UV, frost and bird droppings while letting natural light through almost as if the roof weren't there. Unlike a conservatory — which is fully enclosed and treated as part of the habitable home — a glass veranda is typically open-sided, so air circulates freely and heat doesn't build up in summer.

Glass verandas have become the UK's fastest-growing premium alternative to conservatories. They install in days rather than weeks, rarely require planning permission, and genuinely look good in a way that a polycarbonate-roof veranda never quite matches. Our range covers five glass verandas — from the versatile British-built Haven through to the architectural Vista at the top of the range — all with live UK pricing by size above.

Why choose glass over polycarbonate?

The roof material is the biggest single decision on any veranda. Both glass and polycarbonate will keep rain off, but the experience and finish are very different:

• Sound — glass is virtually silent in rain. Polycarbonate is audibly noisy, which matters if you plan to use the space for dinner or conversation.
• Clarity — glass is genuinely transparent. Polycarbonate is translucent (light passes through, but detail doesn't) and can yellow slightly over decades of UV exposure.
• Finish — glass produces a premium architectural look that increases property value. Polycarbonate is functional rather than decorative.
• Lifespan — toughened safety glass doesn't degrade in UV. Polycarbonate panels typically need replacement after 20–30 years.
• Cost — glass is typically 10–40% more expensive than polycarbonate on the same footprint, with the gap widening on larger builds.

Polycarbonate is the right pick when budget is the primary constraint or the veranda is a purely functional cover (e.g. for a side passage). Glass is the right pick for everything else. For the full comparison, read our Glass vs polycarbonate veranda roof guide.

What glass is used in a glass veranda?

Not all glass is the same. Here's what sits above your head in one of our glass verandas:

• Toughened safety glass (standard) — 8 to 10 mm thick, heat-treated to approximately 5× the strength of untreated glass. Engineered to break into small, blunt cubes rather than sharp shards if ever damaged. This is the BS EN 12150-1 standard and is what every reputable UK glass veranda uses on its roof.
• Laminated glass (optional upgrade) — two layers of toughened glass bonded with a PVB interlayer. Used when extra impact resistance is required (e.g. heavy tree cover, overhead risk) or when acoustic damping is a priority. If ever broken, the PVB holds the fragments in place so nothing falls.
• Solar-control glass (optional) — a micro-thin metallic oxide coating reflects infra-red radiation while letting visible light through. Reduces summer solar gain without making the glass look tinted. Worth considering on south- or west-facing verandas that get strong afternoon sun.
• Self-cleaning glass (optional) — titanium-dioxide coating uses UV to break down organic dirt, which then rinses off in rain. Reduces the frequency of manual cleaning on harder-to-reach roofs.

Unless you specifically upgrade, every glass veranda we install comes with toughened safety glass as standard. Glass spec upgrades are priced transparently at the survey stage and folded into the installed price.

Glass veranda styles

UK glass verandas split broadly into two style families:

• Pitched-roof glass verandas (Haven, Sanctuary, Pavilion) have a traditional sloped roof. They read more classical and tend to suit Victorian, Edwardian and traditional new-build homes. The Haven additionally offers Victorian-style decorative posts — unique to that model — for period properties.
• Flat-roof glass verandas (Horizon, Vista) have a modern cubist look. Zero pitch, clean horizontal lines, often paired with chunky aluminium posts for architectural presence. Flat-roof glass verandas also suit bungalows and other low-eaves properties where a pitched roof physically can't fit. Both our flat-roof models are glass only.

Style is ultimately a personal and architectural choice — and the right one depends on your property rather than any abstract best. During the free survey we'll show you how each model looks against a photo of your actual house.

Benefits of a glass veranda

Beyond the obvious "it looks better than polycarbonate", a glass veranda gives you:

• Year-round usable outdoor space — silent in rain, protected from UV and bird droppings, and unaffected by the heat issues of fully-enclosed conservatories. Most homeowners use the space for roughly 10 months of the year.
• Property value — industry sources suggest a premium glass veranda adds 5–7% to property value, with some installations adding more. It counts as covered, usable floor area in valuations.
• Maximum natural light — glass lets full daylight through, which also brightens the room behind it. Particularly valuable on north-facing elevations that would otherwise feel darker.
• Low-maintenance longevity — toughened glass doesn't yellow, doesn't need replacement, and cleans with standard window-cleaning products. Aluminium frames don't rust, rot or need repainting.
• Flexibility — every model is designed to accept glass walls, sliding doors or louvred panels at install or retrofit. Start open-sided and close it in as budget and use evolve.

Do I need planning permission for a glass veranda?

In most cases, no — the rules for glass verandas are the same as for any modern aluminium veranda, and most installations fall under Permitted Development rights. The usual exceptions apply: listed buildings, conservation areas, raised platforms, front-elevation installations, and certain height or boundary constraints. We check your specific property during the free survey and advise before you commit. For the full rules, see our detailed Veranda planning permission UK guide or our all verandas hub.

How much does a glass veranda cost in the UK?

UK glass veranda prices depend on size, glass specification, post count and any side options. Indicative starting prices at 4m × 3m (the smallest standard configuration), installed and VAT-included:

• Haven — from around £6,000 (glass, British-built, 60-year lifespan)
• Sanctuary — from around £6,400 (glass, Dutch-built, widest post spans)
• Pavilion — from around £6,000 (glass, British-built, up to 6m deep)
• Horizon — from around £9,200 (glass, Dutch-built, flat roof, bungalow-friendly)
• Vista — from around £11,800 (glass, British-built, chunky 150mm posts, flat or apex)

Starting prices are shown on each card above — tap Get My Quote for a written price for your exact dimensions. Every quote includes installation, VAT, and standard glass spec with no hidden add-ons. For a detailed breakdown including side options, LED lighting and heating, read our Veranda costs pricing guide.

Is there a maximum size for a glass veranda?

Per-unit limits range 4–6 metres depth and 4–7 metres post span depending on the model. But overall width is not capped — multiple glass verandas can be installed side-by-side as one continuous run with a shared gutter line, which is how we cover 10m+ elevations or L-shaped corners. Extra-large glass roof spans also benefit from the laminated-glass upgrade covered above.

How long does glass veranda installation take?

Physical installation is usually 1–3 days on site; total end-to-end timeline from enquiry to installed glass veranda is typically 4–8 weeks. British-built models (Haven, Pavilion, Vista) ship faster than Dutch-built (Sanctuary, Horizon). Your survey confirms the exact lead time before you pay any deposit.
