Bonded and insured is one of those phrases that appears on every contractor’s van and website, and most homeowners treat it as a single reassurance. It is two separate things, they do different jobs, and understanding the difference changes how you evaluate a contractor.
What the bond is
A surety bond is not a pot of the contractor’s money sitting in reserve. It is a guarantee purchased from a surety company. If a valid claim is established against the contractor and they do not satisfy it, the surety pays out — and then pursues the contractor for the amount.
That last part matters. The bond is not a benefit the contractor receives; it is an obligation that costs them if used. A contractor with a history of bond claims will find bonding harder and more expensive to obtain, which is part of why the system works.
What it is not
It is not liability insurance. Insurance covers damage caused during the work — a foot through a ceiling, a vehicle into a fence, a fire started by a tool. The bond covers claims arising from the contractor’s failure to meet their obligations, such as work abandoned or not performed as agreed.
It is also not unlimited. The bond is a defined amount, and if multiple claimants pursue the same contractor, earlier successful claims reduce what remains for later ones. A contractor in trouble may have several claims against a single bond.
Why the expiry date matters more than its existence
Homeowners who check the bond at all tend to check whether one exists. The more useful question is when it expires.
A bond that lapses partway through your project leaves you without recourse for the remainder of it, which is precisely the period during which problems tend to surface. If you are commissioning work spanning several weeks or months, check that the bond covers the whole span, and raise it if it does not.
How a claim actually works
Claims against a contractor’s bond follow a formal process with specific requirements and time limits. The details matter and the deadlines are real, which is a good reason to seek proper advice promptly rather than working it out slowly on your own.
What you can do from the outset is keep the documentation that any claim will depend on: the written contract, the agreed scope, the payment schedule, receipts for what you have paid, dated photographs of the work, and any written exchanges about problems. A claim supported by a paper trail is in a materially different position from one supported by recollection.
What this means practically
Treat the bond as real but finite protection. It is a genuine reason to prefer a registered contractor over an unregistered one, and a genuine reason to check the expiry date rather than the checkbox.
It is not, however, a substitute for the more basic protections: not paying large sums upfront, tying payments to progress rather than dates, and getting the scope in writing. Recovering money through a bond claim is always harder than not having handed it over prematurely.
