Security
A retention bond instead of retention: is it worth it?
Retention is you lending the client money interest-free for two years as proof you will fix your own snags. A retention bond buys the same reassurance from a surety and leaves the cash in your account. Whether the swap pays depends on three numbers, and only one of them is the premium.

The swap is simple to state: instead of the client deducting retention from each payment, a surety issues a bond promising the client the same money if you fail to return and make good. You get paid in full through the job; the client keeps security; the surety takes a premium for standing in the middle.
What it actually costs you
- The premium, an annual percentage of the bonded amount, priced on your covenant, no honest figure fits every firm, so get quotes rather than folklore. Compare it with what conventional retention costs you: 5% of turnover permanently outstanding, financed at your overdraft rate, plus the chasing that stranded releases demand. For many small firms the financing cost alone exceeds a plausible premium, which is why the question is worth asking at all.
- The counter-indemnity. The surety does not take your risk, it takes the client’s: if the bond pays out, the surety recovers from you, and the facility may want security. A bond changes who holds the cash meanwhile, not who ultimately answers for your defects.
- Facility headroom: bonded amounts sit on your surety line, and a firm running several bonds finds the line itself becomes the constraint.
The wording, same two questions as every bond
As with the advance payment bond, the danger lives in two clauses. On-demand or conditional: a conditional bond pays on established default, an on-demand one pays on request, argue later; on-demand retention bonds hand a disgruntled client a lever conventional retention never gave them, since deducted retention at least required notices to raid. Reduction and expiry: the bond should step down at the events retention would have released on, practical completion and making good, and expire on the second, with the release chased like any other, because sureties do not cancel their own exposure unprompted.
When it genuinely pays, and when it does not
Pays best: bigger jobs where 5% is serious working capital, clients with a record of stranding releases, and firms whose covenant prices well. Pays worst: small jobs where the premium’s minimum eats the saving, one-off domestic clients, for whom a surety product is an alien document, on a homeowner job the practical alternative is simpler, a modest defects holdback written into the quote instead of percentage retention, and firms whose real problem is that they fund retention down the chain while paying to escape it upwards: fix the chain first, the whole cash picture is measurable.
What to do this week
1. Measure your retention exposure: total held across all jobs, and what financing it costs you a year. That number decides if this page matters to you.
2. If it is serious, get an indicative premium from a broker, and compare like with like: premium plus counter-indemnity terms against financing plus chasing.
3. Raise it at the next tender, not mid-job: a retention bond offered in the contract negotiation is a term; proposed in month six it reads as a cash flow confession.
Where the information stops
Bond wordings move real risk in single sentences, and the counter-indemnity is a personal-guarantee-adjacent document deserving the same caution: both go past a broker or solicitor before signature, and this page’s arithmetic is a reason to ask the question, not a substitute for the quote.
