If my licence has no insurance condition, can a client still lawfully require me to hold cover?

Yes. A contract requirement does not depend on a licence condition existing — it is a term the parties agree to, and it binds as a matter of contract regardless of what the licence itself says.

Can I refuse a contract clause on the basis that my licence does not require it?

That is a negotiating position, not a legal exemption. The clause is a term of the specific agreement being offered, and whether to accept, question or decline it is a commercial decision rather than one the licence settles.

Whose insurance clause wins if a contract and a licence condition genuinely conflict?

A licence condition is a regulatory floor and cannot be contracted below. A contract asking for more than the licence condition requires is enforceable as agreed, so in practice the stricter of the two ends up being the one that has to be met.

Contract requirements vs licence requirements

In short

A licence condition, where one exists, is set by a regulator and applies to that licence class. A contract requirement is set by whoever a business is dealing with and applies only to that agreement.
A business can hold a fully compliant licence and still fail a contract’s insurance clause, because the contract can ask for more — a higher limit, a different class, a specific notation.
The reverse also happens: a contract can ask for less than a licence condition already requires, in which case the licence is the binding floor regardless of what the contract says.

A business that holds a licence in good standing sometimes assumes that settles the insurance question for any job it takes on. It does not. A licence condition, where one even exists, is a floor set by a regulator for that class of work generally. A contract can set its own, separate requirement on top of it, and the two are checked differently, by different people, for different reasons.

Understanding the difference matters most for the licences that carry no condition at all — the majority — because for those, the contract is not adding to a regulatory requirement. It is the only requirement in the room.

Two different tests, two different sources

A licence condition is written by the licensing body and applies uniformly to everyone holding that licence class in that state — demolition’s public liability certificate wording is an example, and it does not vary between one demolition contractor and another.

A contract requirement is negotiated or imposed for one relationship: a head contractor’s subcontract, a landlord’s lease, a client’s onboarding pack. It can name a class, a limit, a notation or an insured entity that has nothing to do with what any regulator asks for, because it is answering the other party’s own risk question rather than a public licensing one.

Where a compliant licence still fails a contract

A demolition contractor holding a licence with a fully compliant public liability certificate can still fail a specific principal’s contract clause if that clause asks for a higher limit, an interested-party notation, or a class of cover the licence condition never required in the first place. Passing the licence check settles nothing about the contract check.

This is the more common failure mode for licences that carry no condition at all: there is no regulatory floor to point to, so the contract clause is being measured against whatever cover the business happens to hold, not against anything the licence guaranteed.

What to do when a certificate falls short of a contract

Where a licence condition is the higher bar

The relationship can run the other way too. A contract that asks for a modest, generic level of cover is not a reason to think a stricter licence condition can be relaxed to match it — the licence condition binds regardless of what any one contract asks for, because it is a regulatory requirement rather than a negotiated term.

Where the two conflict in substance rather than just in wording, the licence condition is the one that cannot be negotiated away by agreement between two contracting parties.
