It seems only fair that a party should be paid a reasonable amount for the work it performed. But the courts have taken a nuanced approach to quantum meruit claims

Anyone dealing with construction disputes will be familiar with claims based on 鈥渜uantum meruit鈥. This means roughly 鈥渁 reasonable amount for work performed鈥. The claim is usually made when there is no contract 鈥 for example, because the parties were unable to agree key terms. It can also arise where there is a contract, but no agreement on price.

If such a claim is made out, how does the court then assess the amount due? A recent talk to assorted construction lawyers called 鈥淨uantum meruit: right or remedy?鈥 organised by TECBAR, the construction barristers鈥 association, contained useful guidance. The talk was given by Professor Graham Virgo of Cambridge University. It covered some areas that are of interest for lawyers only. However, the clear summary of where the law is at the moment was helpful for anyone in the construction industry dealing with this type of claim.

As a typical construction-related example (not one of Virgo鈥檚), suppose that a contractor enters into a two-stage tender arrangement, by which it is to work up an employer鈥檚 outline design, price the works packages, prepare invitations to tender and then assess the tenders. Assume that the employer is impatient, so that the parties never agree the scope of the services or the sum that the contractor is to be paid.  When the tenders are back, the employer is unhappy about the prices. He accuses the contractor of overengineering and of ignoring his need to cut costs. So he ends the contractor鈥檚 involvement and later proceeds with a much cheaper version of the scheme 鈥 and a different contractor.

In this scenario, the contractor undoubtedly has a claim for services performed. But how is the value of those services assessed? Should one look at the cost to the contractor of providing the services, or the benefit to the employer of receiving them 鈥 or a bit of both? 

Can the amount of the benefit be reduced to take into account the fact that the particular employer values the services at less than their market value? Yes, said the court

As Virgo explained, claims for quantum meruit are based nowadays on the principle of unjust enrichment. Applying this to the above scenario, the employer has been 鈥渆nriched鈥 by, or has benefitted from, the services carried out for him, and it would be unjust for him to retain the benefit without paying. Quantum meruit is merely the remedy, not the right or cause of action in itself.

The leading case is now Benedetti vs Sawiris (2013) a decision of the Supreme Court. Here, the claimant, Benedetti, provided services for an employer by way of searching for suitable co-investors in an Italian telecommunications company that was being sold. The original agreement between the parties was abandoned when the co-investors lost interest, but the employer decided to go it alone and eventually acquired the company. The question then arose as to what he should pay the claimant for his work.

The court said that unjust enrichment is primarily about assessing the amount by which the benefitting party has been enriched, not the costs incurred by the party performing the services (though such costs could be relevant in quantum meruit claims where there is a contract, but no agreement about price). The starting point was the objective market value of the services. So in the scenario above, the cost to the contractor might be some evidence of market value, but nothing more.

Claims are often prepared with the contractor simply printing off a schedule of his costs and expecting payment. That now looks wrong

Can the amount of the benefit then be reduced to take into account the fact that the particular employer values the services at less than their market value? Yes, said the court.

As a judge put it in Benedetti: 鈥淚 see no reason why a court should not take into account a defendant鈥檚 subjective opinion of the value of the claimant鈥檚 services in order to reduce the value of them to him, provided of course that the court is satisfied that it is his genuine opinion.鈥 So, returning to the two-stage tender example, the employer might be able to prove that he would not have chosen to pay for some of the over-engineered services, had the parties discussed them at the outset.

Quantum meruit is sometimes the only way for a contractor to get paid. Yet claims are often prepared making no reference to unjust enrichment, and with the contractor simply printing off a schedule of his costs and expecting payment. That now looks wrong. Market value, with potential 鈥渄evaluation鈥 to account for the actual position of the particular employer, appears to be the more correct legal approach.
