What is formwork contractors insurance?
Formwork contractors insurance is cover for firms that design, erect and strike the temporary moulds and supports that hold concrete while it sets. It combines employers' and public liability with cover for formwork systems, falsework and plant, and can add professional indemnity where the firm designs its own temporary works.
The big losses in this trade happen in minutes. A shutter that bursts or a falsework that buckles during a pour can injure a crew, wreck the reinforcement and leave tonnes of setting concrete to break out, so insurers look closely at how your temporary works are designed, checked and signed off before concrete arrives.

Pour failures
Third party damage and injury when shuttering bursts, ties fail or falsework collapses under wet concrete, subject to how the policy treats damage to the works themselves.
Owned formwork systems
Panels, beams, props, table forms, climbing systems and timber shuttering in your yard, in transit and on site.
Hired-in formwork and plant
Formwork systems, props and access hired from suppliers, where the hire terms charge you for loss, damage and the hire running until replacement.

Temporary works design
Errors in drawings, calculations or checks for formwork and falsework your firm designs, covered by professional indemnity rather than liability.

Contract works
The concrete frame, reinforcement and materials you are responsible for, where your subcontract places that risk on you rather than the main contractor.

Tools and site equipment
Saws, drills, vibrating pokers, power floats and hand tools in containers, on site and in vehicles.
Extras formwork contractors consider
- Fleet insurance: crew vans and flatbeds moving formwork between sites
- Group personal accident: set payments for operatives injured on site
- Legal expenses cover: disputed valuations, contra charges and retentions
- Commercial combined insurance: a yard and workshop where shutters are made and stored
Which firms is formwork contractors insurance for?
It suits established firms whose work is forming, supporting and casting concrete. Typical buyers include:
Digging and drainage too? Excavation, foundations and drainage work are covered on our groundwork contractors insurance page, and roads and bridges by civil engineering insurance.
- Reinforced concrete frame contractors: formwork, rebar and concrete placing for multi-storey frames under main contractors
- Shuttering carpenters on housing sites: foundation, slab and retaining wall shuttering for house builders and groundworkers
- Falsework specialists: propping and support systems for slabs, bridge decks and transfer structures
- Climbing and slip forming contractors: cores, lift shafts and stair towers rising floor by floor ahead of the frame
- Infrastructure formwork contractors: bridges, culverts, abutments and water treatment structures for civil engineering firms
- Basement and retaining wall specialists: below-ground concrete next to existing buildings, often with propping and waterproofing
- Steel fixing contractors: cutting, bending and fixing reinforcement ahead of the pour
- Formwork hire firms with erection crews: supplying systems and labour, which blends hire and contracting risks in a similar way to plant hire with operators
How much does formwork contractors insurance cost?
Formwork is rated as a heavy construction trade. Underwriters build the premium mainly from these points.
Wage roll and labour-only crews
Insurers rate employers' liability against the pay of carpenters, fixers and labourers, including labour-only gangs counted as employees.
Height and structure type
Multi-storey frames, cores and bridge decks carry more risk than ground-level slabs and foundation shuttering.
Design responsibility
Firms that design their own temporary works need professional indemnity, priced on fees or turnover and the complexity of the structures.
Value of formwork equipment
Owned and hired systems are rated on their replacement value and how they are stored and moved.
Contract terms
Subcontracts that make you responsible for the works, or require high liability limits, increase the cover you need.
Claims and procedures
Past collapses or pour failures weigh heavily, while documented checks and permits to load show good control.
What formwork contractors insurance excludes
Formwork claims are often disputed over the points below.
- Breaking out and recasting concrete that is out of tolerance, honeycombed or poorly finished because of your own workmanship
- Design errors in temporary works, unless professional indemnity has been arranged
- Damage to the works themselves when the subcontract leaves that risk with the main contractor's policy
- Wear and tear to panels, plywood and props from normal use
- Liquidated damages and programme delay costs passed down by the main contractor
- Loss of hired formwork that cannot be accounted for at the end of the hire, depending on the policy terms
- Cranes used under a hire rather than a contract lift, unless declared and covered
- Gradual pollution, such as washout water repeatedly entering drains, which most liability policies exclude; see environmental liability insurance
Temporary works or permanent works: where formwork claims land
Formwork sits between two kinds of construction risk. Knowing which side a loss falls on shows which policy, and whose policy, is likely to respond.
| Feature | Temporary works (formwork and falsework) | Permanent works (the concrete) |
|---|---|---|
| What it is | Shutters, props and supports removed after the pour | The slab, wall or frame left behind |
| Typical loss | A burst shutter or buckled prop | Cracked, misaligned or collapsed concrete |
| Usually insured by | Your equipment cover or the hire terms | The contract works policy named in the contract |
| If the design was wrong | Your professional indemnity, if you designed it | The designer's professional indemnity |
| Not covered by either | Normal wear to panels and props | Recasting concrete purely because of poor workmanship |

How much does formwork contractors insurance cost?
It is priced on your wage roll, turnover, the heights and types of structure you build, whether you design temporary works, the value of your formwork and your claims record. A frame contractor working on high-rise cores pays a different rate from a firm shuttering house foundations.
Is a formwork collapse during a pour covered?
Injury and damage to other people's property are covered by your liability sections. Damage to the concrete and reinforcement depends on who insures the works under the contract, while correcting your own faulty work is normally excluded.
Do formwork contractors need professional indemnity?
Yes, if your firm designs or checks temporary works. Liability policies usually exclude design errors, so professional indemnity is needed for a claim that a formwork or falsework design was wrong. Firms that only build to others' designs may not need it.
Does formwork contractors insurance cover shuttering and formwork hire?
Hired-in shuttering and formwork can be covered under a hired-in plant section. Formwork suppliers usually charge for loss, damage and continuing hire, so it is worth checking the limit covers the largest system you hire at any one time.
Who is responsible for a crane lift of formwork?
It depends on the arrangement. Under a standard crane hire, even with an operator supplied, the hirer usually plans the lift and carries responsibility for the operator's actions and damage to the crane, while under a contract lift the crane company does. Declare any crane hire so the insurer can confirm cover.
Are steel fixers covered under the same policy?
Usually, if reinforcement fixing is declared as part of your work. Employed and labour-only steel fixers are counted in your wage roll, and bona fide steel fixing subcontractors should hold their own cover, which you check before they start.
Is concrete that fails its strength tests covered?
Generally no. Concrete that does not reach strength because of the mix or placing method is treated as a defect, not accidental damage. If a supplier's concrete was faulty, the claim is usually against the supplier rather than your policy.
Can I get cover after a previous formwork failure?
Usually. Insurers will want the cause, the cost and the changes made since, such as independent design checks, permits to load or new inspection routines. Setting this out clearly helps the broker present the risk well.
