Civil Engineering Contractors Insurance
Two numbers decide how this trade is priced, and neither is turnover. How deep you go, and what is buried where you are going.
The reason is the shape of the loss. Put a bucket through a fibre trunk route and the repair is trivial next to what the network operator claims for the customers who lost service. It is one of the very few construction risks where the claim has no relationship at all to the size of the contract, and insurers price accordingly.
If your work is closer to landscaping and shallow drainage than to infrastructure, our landscaping and groundworks page is written for that instead and will fit you better.
How Much Is Civil Engineering Contractors Insurance?
Cover for a sole trader groundworker with up to £2m of public liability typically starts at about £16.88 a month, roughly £203 a year. That is the entry point rather than the average: one person, liability only, with nothing for tools, employees or the job itself. Employ anyone and employers' liability becomes a legal requirement, and from there the price is driven by wageroll and by the work you take on rather than by the trade.
What moves the price is the same in every trade: turnover, how many people work under your direction, the work you take on, and your claims record. We are a broker, so we take it to several insurers rather than quoting one. Call 02382 000820 for a realistic figure.
What Civil Engineering Contractors Insurance Covers
Public Liability Insurance
Injury and damage to other people's property, which here means struck services, neighbouring land and the buildings alongside your dig. £5m is common on housing work and £10m where utilities, highways or rail are anywhere near.
Employers' Liability Insurance
Required by law and included as standard. Excavation is high hazard work, so shoring practice, banksman use and operator tickets carry real weight in how it is rated.
Contract Works Cover
The dig, the drainage, the concrete and the materials on site. Storm water filling an open excavation and washing out new work is the claim that turns up every winter.
Contractors Plant
Excavators, dumpers, rollers and attachments, owned and hired. Hired plant needs the continuing hire charges included, because they run separately from the value of the machine.
Professional Indemnity
Where you design temporary works. Shoring and propping design is the piece most contractors forget they are doing, and it is where the serious claims sit.
What Your Policy Expects Before You Dig
Most wordings on this class say something about establishing where services are before breaking ground, using drawings and detection rather than one or the other. Where that cannot be shown afterwards, a strike claim becomes an argument.
The practical answer is unglamorous: keep the scan record, the permit to dig and the utility drawings with the job file. It takes a couple of minutes per excavation and it is the difference between a claim that is paid and a claim that is negotiated.
The Three Metre Line
A depth restriction, most often three metres, sits in a lot of standard construction wordings, and civils work goes past it routinely.
The danger is not that a deeper claim gets reduced. It is that going beyond an undeclared limit can put the whole excavation outside cover, turning something manageable into something uninsured. Tell us your genuine maximum rather than your usual, because writing it in costs less than people assume.
Contractors With A Service Strike On Record
A struck main is the claim that follows this trade around, partly because the numbers are large and partly because insurers read it as a procedural failure rather than an accident.
That is exactly why it is worth explaining. A contractor who has since introduced permits to dig, mandatory scanning and trial holes has removed the cause, and an underwriter who is told that will treat the history differently from one who is handed a loss run.
We would rather build that submission than let you take a rate set by a system that never read it. Call 02382 000820.
What We Need To Quote
- Turnover by discipline: drainage, highways, earthworks, structures, utilities
- Your genuine maximum working depth
- How you establish where services are before digging
- Whether you work near railways, motorways or watercourses
- Plant values, and the split between owned and hired
- Whether temporary works design is done in house
- Five years of claims, particularly strikes and plant theft

Common questions
How much is civil engineering and groundworks insurance?+
A sole trader groundworker typically pays from about £16.88 a month, roughly £203 a year, for up to £2m of public liability. Note that is already three times what a carpenter pays, and it is the floor rather than the average, because excavation is rated on what you might hit and how deep you go. Add plant, a wageroll and depths past three metres and it moves again. Call 02382 000820 with your maximum working depth and plant values and we will price it properly.
Am I covered if I hit a cable or a water main?+
Public liability normally answers for damage to third party services and anything that follows from it. The qualification is that many wordings expect you to have established where services were beforehand using drawings and detection equipment, and where that cannot be evidenced the claim gets argued. Keeping the scan record and permit to dig with each job file is what protects it.
Does my policy cover digging deeper than three metres?+
Not automatically. Three metres is the restriction that appears most often in standard wordings, and civils work passes it routinely. Going beyond an undeclared limit can take the entire excavation exposure outside cover rather than just reducing what is paid, so declare your real maximum depth rather than your typical one.
Do I need professional indemnity for temporary works design?+
If you design shoring, propping or falsework yourself, yes. That is design, and a failure is both a safety event and a design liability. Public liability pays for the injury and the damage; it does not pay because the design was wrong. Plenty of contractors carry professional indemnity for permanent works and never think about temporary works, which is where the more frequent claims are.
Can I get cover after a service strike claim?+
Yes, and the way you present it matters more than the claim itself. Insurers read a strike as a process failure, so showing the process changed is what shifts the conversation: permits to dig, mandatory scanning, trial holes. Handed a bare loss run, a rating system will just load you. Call 02382 000820 and we will put the explanation in front of somebody who reads it.
