Safety glass in shopfronts
Shopfront glass in doors, near doors and at low level needs to be safety glass or otherwise protected, and large glazed areas need manifestation. England uses Approved Document K, Wales Approved Document N, Scotland its Technical Handbook and Northern Ireland Technical Booklet V.

Where do shopfronts need safety glass?
A shopfront needs safety glass in doors, in side panels beside doors up to 1500 mm above the floor, and in walls up to 800 mm above the floor. These are the critical locations, where people are likely to walk into glass. The rules are in different documents in each nation, and the figures below are the ones we have read.
| Nation | Document | Where it applies |
|---|---|---|
| England | Approved Document K, requirement K4, Diagram 5.1 | Critical locations in doors, side panels and walls, with the 800 mm and 1500 mm heights and the 300 mm zone beside a door |
| Wales | Approved Document N, requirement N1 | Floor to 800 mm in walls and partitions. Floor to 1500 mm in a door, or in a side panel close to either edge of the door |
| Scotland | Technical Handbook, Non-domestic, clause 4.8.2 | Within 800 mm of the floor, part of a door leaf, or within 300 mm of a door leaf and within 1.5 m of the floor. Refers to BS 6262-4 |
| Northern Ireland | Technical Booklet V | Check the current booklet. Your building control officer can confirm the zones |
Workplace law applies on top of this. Regulation 14 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires transparent surfaces in walls, partitions, doors and gates to be of safety material or protected against breakage where needed for health or safety, and to be marked so that they are apparent.
What counts as safety glass?
Safety glass breaks in a way that limits injury, and in England it should meet Class 3 of BS EN 12600 or Class C of BS 6206 in a critical location. For a door or side panel with a pane wider than 900 mm, the English guidance raises this to Class 2 of BS EN 12600 or Class B of BS 6206.
Two types of glass do most of the work in shopfronts:
| Toughened | Laminated | |
|---|---|---|
| How it is made | Heat treated to make it stronger | Two or more panes bonded to an interlayer |
| How it breaks | Into small, relatively blunt pieces | Cracks but stays in the frame on the interlayer |
| After breaking | The opening is left clear | The opening stays closed until replaced |
| Can it be cut after making | No | Yes, by a glazier |
| Good for | Doors, frameless fronts | Security, large panes, overhead glass |
Safety glass normally carries a permanent mark, usually in a corner. Ask to see it, and keep the supplier's details with your premises file. Approved Document K also allows thick annealed glass in some large panes supported on all four edges, and a permanent protective screen as alternatives.
Does laminated glass count as security glass?
Not automatically, because safety and security are tested differently. BS EN 356 classifies security glazing against manual attack, from P1A to P8B. In Group A, P1A to P5A, a 4.11 kg steel ball is dropped onto the glass. In Group B, P6B to P8B, hammer and axe blows are counted until an opening is made.
A laminated pane can pass as safety glass and still have a low attack rating. Ask for the rating and not just the word laminated. A shutter does the same job for the rest of the frontage, so read our security guide before setting a glass specification.
What is manifestation, and when do I need it?
Manifestation is a permanent mark on glass that shows people it is there, and shops need it on large uninterrupted areas of transparent glazing. In England, requirement K5.2 and Section 7 of Approved Document K set out how it works, at two levels:
- Between 850 mm and 1000 mm above the floor.
- Between 1400 mm and 1600 mm above the floor.
- As a logo or sign at least 150 mm high, repeated on glazed screens, or a decorative feature at least 50 mm high.
- With contrast from inside and outside in all lighting conditions.
Clause 4.8.2 of the Scottish handbook gives the same two height bands. In Wales, requirement N2 of Approved Document N covers it, and in Northern Ireland, Technical Booklet V.
Some glazing does not need it. Approved Document K lists these examples: glass less than 400 mm wide between frames, glazing with a rail in both height bands, a single pane door with a substantial frame, and a door with a large handle or push plate on each pane. Window lettering can count if it sits at the right height, so plan your vinyls with this in mind.
What does safety glass cost?
Laminated security glazing has a guide price of £195 to £495 per m² plus VAT, supplied and fitted. One pane, measured, made and fitted, has a guide price of £295 to £1,495 plus VAT.
Worked example: a pane 3 m wide and 2.4 m high has an area of 7.2 m². At guide price that is £1,404 to £3,564 plus VAT. On a new shopfront or package, the laminated upgrade has a guide price of £695 to £1,495 plus VAT.
A broken pane needs care too. Replacing the same glass in a critical location may leave you with glass that falls short of today's rules. Regulation 14 of the Workplace Regulations applies whatever the age of the shopfront, so ask for safety glass as the replacement.
How do I check the glass in my shop?
Start by looking in the corner of each pane for a permanent mark. Then walk the frontage with this list:
- Check the door glass for a safety mark.
- Check the panes beside the door, up to 1500 mm.
- Check low panes, up to 800 mm.
- Note any stallriser or rail protecting low glass.
- Look for manifestation on large panes, at the two heights.
- Ask whether any pane has been replaced with plain glass after damage.
If you find plain glass in a critical location, ask for a price to replace it. Contact us or start with the quote tool for a new frontage. A free survey applies to new work.
Common questions
Is all shopfront glass required to be toughened?
No. Safety glass can be toughened or laminated, and it is needed in critical locations. A high level pane away from doors may not need it.
Is toughened or laminated better for a shopfront?
Toughened suits doors and frameless fronts. Laminated stays in place when broken, so it suits security and large panes.
Do window stickers count as manifestation?
They can, if they are permanent, contrast well and sit at the right heights.
Do the same glass rules apply in Northern Ireland?
Northern Ireland has its own Technical Booklet V, published by the Department of Finance. Ask building control there.
