Confined Space Contractor Insurance
Confined space work carries a feature almost no other trade has: the incident frequently injures more than one person, and the second is the one who went in to help.
One Event, More Than One Casualty
A sewer, a tank, a silo, a chamber or an unventilated void can hold an atmosphere that is oxygen deficient, flammable or toxic, and none of that is visible. The first worker goes down and collapses. A colleague follows without equipment because that is the human response, and now there are two casualties and nobody above ground who can retrieve either. That pattern is why the fatality statistics for this work are shaped the way they are.
For insurance it means two things. The limit has to contemplate multiple serious injuries from a single event rather than one. And the policy will be written around your permit system, gas testing and rescue arrangements as conditions, because those are the only things that interrupt the sequence.
What Confined Space Insurance Covers
Public liability at a limit that fits the event
Written to include confined space entry rather than excluding it. £5 million is the floor and £10 million is normal on industrial and utilities contracts, driven by the prospect of multiple casualties from one incident.
Employers' liability
Compulsory at a £5 million statutory minimum and the section most likely to be tested. Underwriters will ask about training, permits and rescue rather than about wageroll, because that is what determines whether an entry goes wrong.
Gas detection, breathing apparatus and rescue equipment
Detectors, airline and self-contained breathing apparatus, tripods, winches and harnesses. Specialist kit with calibration and inspection intervals attached.
Pollution and clean-up
Tank and sewer work puts you alongside contents nobody wants released. A spill during cleaning or removal brings clean-up cost and often a regulator, and sudden release is treated differently from gradual seepage on most wordings.
Property damage to the structure entered
Tanks, chambers and linings are frequently fragile and frequently old. Damage to the asset you entered to clean is a different question from damage to the surrounding property.
Professional indemnity where you inspect or certify
Where your report states that a vessel or chamber is sound, or safe to enter, somebody relies on it. That is advice rather than labour.
Business interruption for the client
Worth checking rather than assuming. A process plant that cannot restart because a vessel was damaged during cleaning is claiming lost production, which is consequential loss rather than physical damage.
Where The Cover Stops
Wordings differ between insurers, so treat these as the usual position rather than as universal fact. Where one of them matters to you, it is worth checking on your own schedule before you need to.
Confined space excluded as standard
As with rope access, most general trades wordings exclude it outright, so the policy can appear adequate and answer none of your work. The permission has to be explicit.
Permit to work as a condition
Insurers routinely make a permit system a condition of cover. An entry made without one, however routine the job felt, can breach the policy as well as the regulations.
Atmospheric testing and monitoring
Pre-entry testing and continuous monitoring are commonly conditions, with calibration records expected. An incident following an untested entry is among the cleanest declines an insurer can make.
Rescue arrangements
Where cover requires a rescue plan and equipment, having neither is a breach. In practice a top man with a tripod and a retrieval harness is the difference between an incident and a fatality, and insurers know it.
Gradual pollution
Many wordings cover a sudden and accidental release and exclude gradual seepage. On tank and sewer work that distinction decides a great many claims.
Hot works inside a vessel
Cutting or welding inside a space that has held flammable product is a separate and much larger risk, usually requiring gas freeing, certification and specific agreement.
The Rescue Plan Is The Policy
If there is one document that determines both the outcome of an incident and the response of an insurer, it is the rescue arrangement, and it is the one most often treated as a formality.
A plan that says emergency services will attend is not a rescue plan. Ambulance and fire crews take time to arrive and longer to prepare an entry, and an unconscious casualty in a toxic or oxygen deficient atmosphere does not have that long. What works is a top man who never enters, a tripod and winch already rigged, a retrieval harness already fitted, and breathing apparatus on the surface ready for a trained rescuer.
It is also the thing to have exercised rather than written. A team that has practised a retrieval knows how long it takes and how awkward it is; a team that has only read the plan does not. Insurers ask whether it has been exercised, and the answer changes the conversation.
Why The Limit Is Set Differently Here
In most trades the limit is sized against a building or a household. In confined space work it is sized against the realistic prospect of several serious injuries arising from one entry.
That is not a theoretical concern. The characteristic incident involves an initial casualty and at least one would-be rescuer, and a multiple fatality claim moves through a £5 million limit without difficulty once dependency claims and costs are included. Which is why industrial and utilities contracts specify £10 million routinely rather than exceptionally, and why accepting a £2 million quote because it was cheaper is a false economy of the most expensive kind.
The practical approach is to start from what your contracts require, treat £5 million as the absolute floor regardless, and look at £10 million the moment you have more than one person entering.
Tank And Vessel Work Brings Pollution With It
Cleaning something out means taking the contents somewhere, and that is where a second class of claim comes from.
An interceptor, a fuel tank, a slurry store or a process vessel holds material that is a pollutant the moment it leaves containment. A failed hose, an overfilled tanker or a damaged lining during cleaning can put product into a drain, a watercourse or the ground, and the cost is clean-up and remediation rather than repair. A regulator is likely to be involved, and the clean-up bill frequently exceeds the value of the contract many times over.
Check how your policy treats pollution, and specifically whether gradual seepage is excluded while sudden release is covered, because the distinction is standard and consequential. Then control it operationally: bunding, hose inspection, and not relying on a single valve.
Standby Rescue For Other Contractors
A growing part of this trade is providing the rescue cover rather than doing the entry, and it is a different exposure that policies often have not been told about.
If you are engaged as standby rescue for somebody else's entry, you have taken on a service obligation with a performance element: to be present, equipped, competent and able to retrieve. A failure there is not merely a contractual problem, because the consequence is a casualty who was not recovered. Expect the contract to pass liability towards you and expect to be asked for a higher limit than the size of the fee suggests.
Make sure the schedule describes it. A policy written for confined space entry does not automatically contemplate being paid to rescue somebody else's employees, and that is a conversation to have at renewal rather than afterwards.
How To Choose A Broker For Confined Space Work
Most trades policies exclude this work, so the first question is whether it can be placed at all. We are an FCA regulated broker and will not tell you we are the best choice. These are the questions that decide it.
Does the wording explicitly permit confined space entry?
Not silence, and not a height limit. An explicit permission. Ask to see it, because a policy that excludes the work can still be sold to you as trades cover.
Is the limit set against a multi-casualty event?
A broker quoting £2 million has sized it against a single injury. The characteristic incident here involves a casualty and a rescuer, which is a different number entirely.
Have permits, testing and rescue been discussed as conditions?
They will appear on the schedule as conditions, so you need to know exactly what is required of you. A broker who has not raised them has not read the wording either.
How is pollution treated, sudden against gradual?
On tank and sewer work this decides claims. Most policies cover a sudden release and exclude gradual seepage, and you should know which side your likely incident falls on.
Is standby rescue for others covered?
If you provide rescue cover for other contractors, that is a service obligation rather than an entry, and the schedule has to say so.
Will it go to an underwriter who reads the submission?
Your permit system and rescue arrangements are what make this placeable. A rating engine cannot see them, which is why an instant decline tells you nothing.
Factually, here is what we do against those questions. We confirm in writing that confined space entry is permitted rather than relying on silence, we size the limit against a multi-casualty event rather than a single injury, we tell you exactly what the permit, testing and rescue conditions require of you, we establish how pollution is treated both ways, and we put your procedures in front of an underwriter who reads them. We are a broker, so it goes to several insurers rather than one.
This work is named in the appetite of one of the insurers we deal with, which is why it can be placed rather than declined. We also insure drainage contractors and industrial cleaners, so the adjacent work is familiar ground.
What Moves The Price
Every policy is priced on the business behind it. These are the things that move the premium:
- The limit of indemnity, sized against a multi-casualty event
- Your permit to work system and who authorises entries
- Atmospheric testing, monitoring and calibration records
- Rescue arrangements, and whether they have been exercised
- The spaces you enter, and what they have contained
- Whether any hot works take place inside a vessel
- Whether you provide standby rescue for other contractors
- Training records and claims history
We are a broker, so we take it to several insurers rather than quoting one. Call 02382 000820 for a quote.

Common questions
What insurance do confined space contractors need?+
Public liability written to permit confined space entry explicitly, at a limit sized for a multi-casualty event: £5 million as an absolute floor and £10 million routinely on industrial and utilities contracts. Employers' liability is compulsory at a £5 million statutory minimum and will be underwritten on your permits, testing and rescue arrangements rather than on wageroll. Then specialist equipment cover for detection and breathing apparatus, pollution and clean-up for tank and sewer work, and professional indemnity if you certify that a space is sound or safe to enter.
Why does confined space work need such a high limit?+
Because the characteristic incident produces more than one casualty. The pattern is well established: an entrant is overcome by an atmosphere that cannot be seen, a colleague follows to help without equipment, and there are two casualties and nobody able to retrieve either. A claim involving multiple serious injuries or fatalities moves through £5 million without difficulty once dependency claims and costs are included. That is why industrial and utilities contracts specify £10 million as a matter of routine rather than as an exception.
Is a permit to work a condition of my insurance?+
Very commonly, yes, and that makes it materially different from good practice. Where a permit system appears on your schedule as a condition, an entry made without one can breach the policy irrespective of how routine the job felt or how experienced the team was. The same applies to pre-entry atmospheric testing and continuous monitoring, with calibration records expected. An incident following an untested entry is among the cleanest declines an insurer can make, so the paperwork is doing two jobs at once.
Does my policy cover a rescue going wrong?+
It depends on whether rescue was part of what you declared. For your own entries, a rescue attempt by your own team is within the work, and your rescue arrangements will usually be a condition of cover rather than an extra. Where you are engaged by somebody else as standby rescue, that is a different proposition: you have taken on a service obligation to be present, equipped and able to retrieve, and a failure has a casualty at the end of it. That needs declaring on the schedule, because a policy written for entry work does not automatically contemplate being paid to rescue another firm's employees.
Am I covered if we cause a spill cleaning out a tank?+
Usually yes if it was sudden and accidental, and often not if it was gradual, and that distinction is standard across the market so it is worth knowing which way yours falls. A failed hose or an overfilled tanker putting product into a drain or watercourse is the realistic incident, and the cost is clean-up and remediation rather than repair, frequently many times the value of the contract, with a regulator involved. Check the pollution wording specifically, then control it operationally with bunding and hose inspection rather than relying on a single valve.
Who insures confined space contractors in the UK?+
A small market, because most standard trades wordings exclude the work outright and a rating engine will decline it instantly without assessing anything. The insurers who write it do so deliberately, generally through brokers, and confined space contracting is named in the appetite of one of the insurers we deal with. What makes a placement work is the submission: your permit system, testing regime, rescue arrangements and training records in front of an underwriter who reads them rather than scores them.
