The problems with retention
Retention is a percentage (often 5%) of the amount certified as due to the contractor on an interim certificate, that is retained by the client. Half of the amount retained is released on certification of practical completion and the remainder is released upon certification of making good defects.
The purpose of retention is to ensure that the contractor properly completes the activities required of them under the contract.
Retention may als be held by the main contractor on subcontracts, and so on down the supply chain.
In January 2018, following the collapse of Carillion, several main contractors backed a call to put an end to retention payments. Build UK, the Civil Engineering Contractors Association and the Construction Products Association provided a joint submission to the ongoing government consultation, stating that; 'The industry is fully committed to achieving zero cash retention and we believe that Government must introduce legislation to ensure there is zero cash retention within the industry by no later than 2025.'
The construction supply chain payment charter also proposed abolishing retention by 2025.
So what are the problems with retention?
Retentions can be large amounts of money and may cause cash flow problems for parties throughout the supply chain. It has even been suggested that retention clauses do not comply with the Housing Grants, Construction and Regeneration Act (Construction Act), which sets out requirements for the withholding of payments.
Before the amendments were introduced in the 2011 version of the Construction Act, a problem that was particularly prevalent for subcontractors was that the release of the retention monies could be delayed by an act or event that occurred within a different contract, for example, the main contract as opposed to the subcontract. The Act changed this so that the release of retention to subcontractors could not be linked to an occurrence within a main contract that was unrelated. It held that a specific occurrence related to the subcontract is what must trigger the non-release of the monies.
Despite this, some contractors have tried to exploit loopholes to continue delaying retention payments. Contractors have been known to hold onto the retention money for so long that the subcontractor decides to write it off completely and move on to current work. There have even been reports of contractors who have adopted this as their standard operating procedure and consider retention as contributing to their profit margin.
This can be very problematic for subcontractors’ cash flow, especially when a contractors have been reported to retain up to around 2.5% of their turnover for a year or more after a project is complete. It can also create administrative problems for subcontractors in terms of having to maintain records of monies still outstanding and chasing up payment release over a long period of time.
While there are appropriate legal remedies available for such circumstances, they may be judged as being too unwieldy for the sums that are sometimes involved, as well as being time consuming, leading to a break down in relationships which may affect possible future work.
In addition, the risk of non-payment due to contractor insolvency also increases the longer payment is delayed. Retention monies that are held when a contractor fails often end up going to creditors instead of subcontractors, even though the failure is often unrelated to the subcontractor.
Retention can also pose problems for main contractors. For example, when trying to recover retention monies from the client, perhaps in a situation where the client has incorrectly identified something as a defect.
