In the UK, tempered glass typically costs between £25 and £55 per square foot for standard thicknesses (4mm–6mm), including basic fitting. Premium options such as low-iron, extra-thick, or specialist coated glass can range from £50 to £90+ per square foot. Labour accounts for roughly 35–50% of the total installed cost, with material prices varying by thickness, finish, and regional supplier rates.
If you are planning a renovation, replacing a glass panel, or installing a modern frameless balustrade, understanding how much tempered glass costs per square foot is essential for accurate budgeting. Tempered glass—also known as toughened glass—is widely used across the UK for shower screens, doors, tabletops, balconies, and commercial shopfronts. This guide provides realistic UK market estimates for material, labour, and full installation costs, along with regional comparisons, practical examples, and expert tips to help you make informed decisions and avoid overspending.
The table below summarises the average installed cost of tempered glass in the UK, combining both material and labour. Prices reflect market averages collected from contractor quotations and supplier pricing across England, Scotland, Wales, and Northern Ireland.
| Glass Type | Thickness | Material Cost (per sq ft) | Installed Cost (per sq ft) |
|---|---|---|---|
| Standard Clear Tempered | 4 mm | £12 – £22 | £25 – £40 |
| Standard Clear Tempered | 6 mm | £18 – £30 | £35 – £55 |
| Thick Tempered | 8 mm | £28 – £42 | £50 – £70 |
| Thick Tempered | 10 mm | £35 – £55 | £60 – £85 |
| Thick Tempered | 12 mm | £45 – £68 | £75 – £100 |
| Low-Iron Tempered | 6 mm | £28 – £42 | £50 – £70 |
| Tinted / Coated Tempered | 6 mm | £25 – £40 | £48 – £68 |
Note: All prices are estimated market averages and exclude VAT unless stated otherwise. Always request a written quotation before proceeding.
The cost of the glass itself depends primarily on thickness and any specialist treatments. Below is a breakdown of supply-only material prices from UK glass suppliers and trade counters.
| Thickness | Clear Tempered (per sq ft) | Low-Iron (per sq ft) | Tinted (per sq ft) |
|---|---|---|---|
| 4 mm | £12 – £22 | £20 – £32 | £18 – £28 |
| 6 mm | £18 – £30 | £28 – £42 | £25 – £40 |
| 8 mm | £28 – £42 | £40 – £58 | £35 – £50 |
| 10 mm | £35 – £55 | £50 – £72 | £44 – £62 |
| 12 mm | £45 – £68 | £62 – £88 | £55 – £76 |
Low-iron glass costs approximately 50–70% more than standard clear glass because it offers superior clarity with minimal greenish tint—ideal for frameless balustrades and high-end shopfronts. Tinted glass adds roughly 15–25% to the base material cost.
Labour for tempered glass installation in the UK is typically charged on a per-square-foot basis for larger projects or a day rate for smaller jobs. Below are the estimated labour ranges.
| Labour Type | Cost Range | Typical Scenario |
|---|---|---|
| Per Square Foot Rate | £15 – £30 | Balustrades, large glazing projects |
| Day Rate (per tradesperson) | £180 – £280 | Small installations, shower screens |
| Hourly Rate | £25 – £45 | Minor repairs, single-pane replacement |
Labour costs are higher in London and the South East, where day rates can exceed £300 for specialist glaziers. Most installations require two people for safety when handling large panes, which can increase the overall labour charge.
Where you live significantly impacts the total cost. Below is a regional comparison of average installed prices for 6 mm clear tempered glass.
| Region | Installed Cost (per sq ft) | Typical Day Rate |
|---|---|---|
| London | £45 – £60 | £260 – £320 |
| South East | £40 – £55 | £240 – £300 |
| Midlands | £32 – £45 | £200 – £260 |
| North England | £28 – £42 | £180 – £240 |
| Scotland | £30 – £44 | £190 – £250 |
| Wales | £28 – £40 | £180 – £230 |
| Northern Ireland | £26 – £38 | £170 – £220 |
Prices in London can be 40–60% higher than in Northern Ireland or Wales, largely due to higher labour rates, congestion charges, and elevated business overheads.
Several variables influence the final cost of tempered glass per square foot. Understanding these helps you compare quotations accurately.
Use the following formulas to estimate your project cost. These are estimation guides, not a substitute for professional quotations.
Total Estimated Cost = (Material Cost per sq ft × Area in sq ft) + (Labour Cost per sq ft × Area) + Waste Allowance + Any Additional Charges
While DIY installation may appear cheaper upfront, tempered glass is heavy, brittle on edges, and dangerous if mishandled. For small, low-risk jobs—such as replacing a shelf or a small cabinet door—a competent DIYer may save £100–£250 in labour. However, for structural applications like balustrades, floor-to-ceiling partitions, or external glazing, professional installation is strongly advised. Incorrectly installed glass can shatter, cause injury, and fail building regulations, leading to far higher rectification costs.
| Project | Glass Type | Area | Estimated Labour | Estimated Total (excl. VAT) |
|---|---|---|---|---|
| Bathroom Shower Screen | 6 mm clear tempered | 10 sq ft | £200 – £280 | £420 – £550 |
| Frameless Balustrade | 8 mm low-iron tempered | 40 sq ft | £900 – £1,200 | £2,600 – £3,500 |
| Shopfront Window | 10 mm clear tempered | 25 sq ft | £600 – £800 | £1,700 – £2,200 |
| Glass Door Panel | 6 mm clear tempered | 8 sq ft | £160 – £240 | £320 – £480 |
| Tabletop (Round, Polished Edge) | 10 mm low-iron tempered | 6 sq ft | £80 – £140 | £350 – £520 |
Most UK glazing contractors quote prices exclusive of VAT. Standard-rated VAT at 20% applies to the majority of installations. However, if the work is part of a larger residential renovation or new-build project, a reduced VAT rate of 5% may apply. Always confirm the VAT status before accepting a quotation to avoid unexpected costs.

The average cost of tempered glass in the UK ranges from £25 to £55 per square foot for standard 4 mm to 6 mm thickness, including basic fitting. Thicker or specialist glass such as low-iron can cost between £50 and £90 per square foot.
Most UK contractor quotations exclude VAT at 20%. Always confirm whether the quoted price includes VAT before accepting. Domestic installations may qualify for a reduced VAT rate of 5% under certain energy-saving or accessibility schemes.
Labour costs for tempered glass installation typically range from £15 to £30 per square foot, depending on the complexity of the job, access requirements, and your location within the UK. London and the South East tend to be at the higher end.
DIY installation is possible for small, simple projects such as replacing a single shelf or a small pane. However, for balustrades, shower screens, doors, or large windows, professional installation is strongly recommended due to safety risks, building regulations, and the risk of breakage.
Key cost factors include glass thickness (4 mm, 6 mm, 8 mm, 10 mm, or 12 mm), edge finishing, cut-outs for handles or hinges, whether the glass is clear, tinted, or low-iron, the size of the pane, and any specialist coatings such as anti-glare or self-cleaning treatments.
A typical tempered glass installation for a small to medium project such as a shower screen or a few balustrade panels can be completed within half a day to one full day. Larger projects may take two to three days. Glass toughening at the factory usually adds three to five working days of lead time.
Yes, tempered glass is typically 40% to 70% more expensive than standard annealed glass of the same thickness. However, it is up to five times stronger and shatters into small, blunt pieces rather than sharp shards, making it the safer option for most residential and commercial applications.
