After the Break: A Shopfront Glass Repair Playbook for UK Retailers

A shopfront break is rarely discovered at a convenient hour. It is found by a keyholder at 6.40am, with glass across the pavement, stock visible from the road, and a full day of trading ahead. The decisions taken in the following two hours — board, repair, replace, or wait — determine both the security of the premises and the shape of the insurance claim.
What follows is a practical sequence for independent retailers and facilities managers, including the regulatory and evidential detail that is easy to overlook under pressure.
The first hour: make safe, record, do not tidy
- Do not enter if the structure is uncertain. Toughened glass fragments; laminated glass leaves shards held in place; a distorted aluminium frame may still be carrying load.
- Cordon the frontage. Pedestrians, and particularly children, are the main risk after a break. Barrier tape placed inside the shop protects nobody; secure the pavement side first.
- Photograph before you clear. Wide shots, close shots and a scale reference, with date and time recorded. Insurers and loss adjusters work from images, and a swept floor proves nothing.
- Do not clear up alone. Use cut-resistant gloves, a rigid container, and never a general waste bin.
- Obtain a crime reference for malicious damage. Insurers frequently require one before a claim is processed.
Boarding up: what good looks like
Boarding is a temporary measure, not a repair, and the quality of it affects both security and how quickly you can reopen.
Plywood is cheap, quick and widely available; 18mm exterior grade is a sensible minimum for a ground-floor frontage. Polycarbonate costs more but transmits light and resists impact better, which matters if the board will remain for more than a few days. Whatever the material, it must be fixed into the frame or the masonry — never taped over remaining glass — and it must not obstruct a means of escape. Fire-retardant board is the correct choice where the frontage forms part of a protected escape route or a fire separation.
Two practical points. If the shop is trading, a clear board with opening hours displayed retains custom and deters opportunists. If it is closed, the board should not advertise that stock is inside.
Reading the glass: markings, standards and safety
Every pane in a commercial frontage should carry a permanent mark, usually etched into a corner. The common ones are:
- BS EN 12150 — toughened safety glass, breaking into small blunt-edged fragments.
- BS EN 14449 — laminated safety glass, which holds together when broken and is generally the better choice for full-height or overhead glazing and for security.
- BS EN 14179 — heat-soak tested toughened glass, specified where spontaneous breakage is a concern.
- BS EN 1279 — the standard for sealed insulating glass units.
Design and safety requirements derive from Approved Document K and BS 6262-4, which identify critical locations — doors, side panels, glazing within 800mm of floor level and areas subject to human impact — where safety glass is required. If a broken pane in one of those locations was not safety glass, raise it with your insurer: it is a liability question as well as a repair.
Repair, reglaze or replace
| Situation | Usual course |
|---|---|
| Single cracked pane, frame intact, marking present | Replace the pane. Toughened glass cannot be cut, so it is a full unit. |
| Cracked pane with damaged beading or gasket | Reglaze and renew the bead; water ingress will otherwise recur. |
| Distorted or bent frame, failed fixings | Replace the affected section. Boarding over a failing frame invites further loss. |
| Multiple panes and an aged system | Consider full replacement; patching rarely pays on a frontage over twenty years old. |
| Damage to an automatic door or its glazing | Isolate the door and use a manual alternative until a specialist attends. |
Lead times matter. A toughened unit is usually made to order and may take several working days; laminated glass and standard sizes are often quicker. Ask for a realistic date in writing, and plan temporary security around the repair rather than the reverse.
Evidence for insurers
Keep one folder: photographs, crime reference, dated invoices, the glazier's report, and a note of stock lost or trade interrupted. Business interruption cover is frequently overlooked by small retailers and depends on records made at the time rather than reconstructed later. Where the premises are leased, establish who is responsible for the frontage under the lease before authorising work; recovering the cost from a landlord after the event is rarely straightforward.
Trading through the disruption
The temptation is to reopen as quickly as possible. The safer sequence is to secure, then reopen. Consider a temporary counter set back from the opening, a manual door where a powered one is out of action, additional staff on the frontage at opening and closing, and a reviewed alarm and CCTV position while the frontage is abnormal. If the opening cannot be made genuinely secure, do not trade behind it.
A short checklist
- Make safe and cordon the pavement.
- Photograph everything before clearing.
- Obtain a crime reference where relevant.
- Board securely into the frame or masonry.
- Record all glass markings.
- Obtain two written quotations with lead times.
- Check the lease and notify the insurer.
- Trade only if the frontage is secure.
A broken shopfront is a disruption, not a catastrophe — provided the first few hours are handled in the right order.
