Bob · Retention recovery
Get your retention released when it is due
For subcontractors and main contractors whose retention is still held. Bob dates each release from your contract, works out what is due and chases each release in the right order.
- Set and forget
- A QS in the loop

Use Bob when
- Practical completion has passed and the first share of retention is still held.
- The defects period has ended and the rest has not been paid.
- You are not sure when your retention should be released.
What Bob works out
How much retention is held, and the share due at each release.
When each release falls due: practical completion, then the end of the defects period, plus any period your contract adds.
The final date for payment of each release, counted under section 116.
Whether your release application stands as the sum due, or a default notice is needed.

- The practical completion date
- The defects period
- Any release application you made
When Bob hands the case to a Quantsurv QS
Bob stops chasing and hands the case to a Quantsurv QS for release tied to the main contract, any notice from the payer about the retention, a claim to keep it for defects, possible insolvency, or a release more than six years old.

Questions
When should retention be released?
Usually half at practical completion and the rest at the end of the defects period, but your contract decides. Bob works it out from your terms.
Can they hold my retention until the main contract is finished?
Tying release to another contract may not comply with section 110(1A) of the Construction Act. Bob flags it and hands it to a Quantsurv QS to check.
What if they are keeping it for defects?
Bob hands the case to a Quantsurv QS, because that needs judgement on the facts.
Taking the pain out of payments.
